Accurate air conditioner mounting size 9. All about the outer air conditioner unit

Updated 09/23/2017

Typically, the width of the inner unit of the air conditioner is more than one meter. This is the standard. However, if the unit has a width of less than a meter, about 70 centimeters, it can already be called small. There are also models with a width of about 50 centimeters, but they are completely unpopular, so we cannot say, they are good or not. We also amounted to the ranking of the best and the smallest air conditioners, which buyers are positively opposed.

The smallest split systems

1st place - Ballu BSWI-09HN1 (396 dollars)

However, its dimensions are primarily worthy - 70 × 28.5 × 18.8 cm. Consequently, he perfectly fit into small premises. As for the functional, it is all right: there is an anion generator, a system against ice formation, an inverter! Of course, one of the best compact split systems.

2nd place - Ballu BSWI-12HN1 (440 dollars)

Approximately 440 dollars you can buy Ballu BSWI-12HN1 air conditioning - wall split system with an inverter compressor. Productivity The device is 7.5 m3 / min, cooling 3.3 kW cooling and 1 kW energy consumption. This is more powerful compared to the previous model system, which is also reliable and high-quality.

Despite higher performance, the dimensions remained the same - 70 × 28.5 × 18.8 cm. Having a width of only 70 cm, this model logically fits into our rating. And second place it occupies partly due to the fact that buyers respond about it as an efficient and reliable air conditioner. Of course, the device is worthy of attention.

3rd place - Supra US410-07HA (267 dollars)

Excellent high quality split system. The performance of this air conditioner is 6.33 m3 / min when energy consumption is 850 W.

The internal unit has the following dimensions: 68x25x18 cm, and its width is 2 cm less than the width of the previous ones in the air conditioner rating. At the same time, there are many positive feedback about him in which many buyers first mark its compactness. Also, the model copes well with its direct appointment, - air cooling - so we can recommend it.

4th place - Pioneer KFR20IW (250 dollars)

In just 250 dollars you can buy a compact and very good air conditioner from the Pioneer manufacturer. Productivity model 8 m3 / min, energy consumption with 685 W.

The size of the indoor unit is as follows: 68 × 26.5 × 19 cm. Also deserves the presence of a deodorizing filter and anon generator. Of course it is not chief CriteriaBut a very solid advantage.

In general, it is an excellent budget air conditioning: it is quiet, it has good performance, filters and small sizes.

5th place - Zanussi ZACS-07 HPR (292 dollars)

Wall split-system designed to use 20 squares in room. Its capacity is 7 m3 / min, capacity when cooling 2100 W, energy consumption is 650 W.

There is a fine filter, a deodorizing filter, as well as an anions generator, which makes the model good decision For allergies. In the rating of compact air conditioners, it was allowed to place dimensions - 70 × 28.5 × 18.8 cm.

Air conditioner has a modern and beautiful appearance, it works very quietly and at night does not interfere. It is also reliable that only confirms the 3-year warranty from the manufacturer.

Small mobile air conditioners

Usually mobile air conditioners are small a priori. However, there are rather large models with a width of more than 60 cm. We selected the best compact mobile air conditioners with a width of up to 50 cm. Only those models about which buyers are positively opposed to the rating.

1st place - ELECTROLUX EACM-10DR / N3 (412 dollars)

A great mobile air conditioningwhich will cost the buyer at 412 dollars. This is a very productive mobile block designed to use indoors with an area of \u200b\u200b24 square meters.

Its dimensions are as follows: 45 × 74.7 × 38.7 cm, and one of its main advantages is small dimensions. It is worth noting that this is a pretty serious model. Here are two separate air contours, thanks to which it is produced on cold heavily rises. About the model positive reviewsSo we put it in the first place.

2nd place - Electrolux EACM-12EZ / N3 (447 dollars)

Mobile block with a capacity of 8.167 m3 / min and 3500 W in cooling mode. Compared to the previous model, this is a more compact air conditioner with dimensions of 43.6 × 74.5 × 39 cm.

This is a wonderful model with good quality Assembly, plastic and high performance. Standing, however, note: some buyers complain about noise and the lack of opportunity to regulate the air flow is its shortcomings. Perhaps the only ones.

3 place - Electrolux EACM-12EW / TOP / N3_W (342 dollars)

Mobile monoblock costs 342 dollars and the following dimensions: 43.6 × 79.7 × 39 cm. Its performance is lower compared to previous and is 4.83 m3 / min. Perhaps that is why the cost of the model is lower. However, air conditioning will provide a comfortable microclimate indoor area up to 25 square meters.

High-quality assembly I. good materials, Low noise when working and complete equipment is its advantages. Perhaps the most compact this model will not call, however, it still deserves attention as a small mobile air conditioner for the house.

4th place - Zanussi ZACM-09 MP / N1 (370 dollars)

The Zanussi manufacturer in the development of mobile air conditioners does not lag behind and offers us a Zanussi ZACM-09 MP / N1 model worth $ 370. The performance of this model is small (5.4 m3 / min), but it is quite enough to create a coolness in a room with an area of \u200b\u200b25 square meters.

The dimensions are as follows: 35x70x32.8 cm. The very same air conditioner collects positive feedback, which is not surprising. This is a high-quality and reliable device from the Japanese manufacturer, who has already proven himself from a good side.

5th place - Zanussi ZACM-07 MP / N1 (335 dollars)

The only difference between this model from the previous one - performance. This mobile air conditioner creates an air flow with a power of 4.9 m3 / min and is intended for use in a room of 20 square meters. Otherwise, there are no differences. This is a compact and good mobile block that will serve for many years.

The introduction of new technological solutions into household equipment is often coming against practical expediency. Example climate machinery The most indicative in this sense. So, recently the market is actively filled that are designed to operate indoors. The peculiarities of such systems include the complete elimination of dirty installation operations, which attracts a considerable audience of consumers. But with all the convenience of installation and further content, such models are not capable of approaching the operating characteristics that provide an external air conditioner unit as part of a split system. Another thing is that the owners of external installations have to face troublesome tasks, but already of another kind.

What is an external unit?

The exterior segment included in the Split system complex includes a capacitor, valve interchanges, pipes, dehumidifier filters and a fan. Depending on the modification and structural design, the internal "filling" may vary, but the traditional air conditioner kit with the remote block has exactly such a set of elements. By the way, the most notable differences are observed in the so-called winter systems that provide for the presence of special controllers to control the fan. IN modern air conditioners Multifunctional power switching relays are also used. Such devices are designed for non-standard compressor operation in conditions of elevated or reduced temperatures. Unlike the inner segment, outdoor block No electronic modules - its work is completely subordinated to the mechanical function.

Block dimensions

The outdoor unit is presented on the market in different configurations and forms. And although manufacturers in order to simplify segmentation seek to unify model rules, the choice of sizes is still quite wide. If we talk about the average parameters, it has a width of 770 mm, a height of 450 mm and the thickness has 245 mm. In this case, the radius of the fan is on average varies from 200 to 250 mm. Of course, there are aggregates whose sizes have deviations from these indicators. Thus, in the Mitsubishi line, an external air conditioner unit is presented with an almost square shape, which has 880 mm wide, and in height is 840 mm. As for the parameters of the internal segment, they are not so impressive. These are usually long narrow medium-sized modules - 700 x 200 x 200 mm.

Choosing a place to install the block

Usually, when choosing an optimal point for mounting air conditioners, users are faced with the problems of combining the convenience of operation and protection of the module. For example, the location of the block at the height is best option From the point of view of its safety, but in this case it is complicated and access to the air conditioner with the goal of care. A good solution can be the placement of the module on the wall near the window opening or loggia. It is necessary to take into account other nuances, among which the lack of direct sun rays and permission to install by neighbors, since the noisy unit can deliver the inconvenience to people living at the same level of the building.

In addition, it produces condensate, which will be dripped down. Accordingly, you will have to negotiate with the neighbors on lower floors. In case of successful harmonization of the installation location with other tenants, you can proceed to immediate mounting operations. By the way, another condition for installing an outdoor unit is the possibility of laying communications in the wall.

Installation of an external air conditioner unit

When installing air conditioners, special mounting setswhich includes pipes with flex, brackets with sets of fixing hardware, drainage communications, etc. The physical installation of the segment is carried out using carrier components that are embedded in the walls using anchor elements. At the same stage, brackets are used, the power potential of which is focused on a mass of a particular module. Also installing an external unit of the air conditioner provides its communication connection with the internal segment. To do this, the wall is performed in the wall of the desired diameter, which will allow to organize, except for the main wiring, also laying the vacuum pump and the pressure gauge manifold. At the final stage, it is directly connecting communications between two blocks.

Features of the installation of the indoor unit

When installing evaporative, that is, the internal module of the air conditioner system, it is especially important to comply with the correct position of the unit. Usually this block is mounted directly under the ceiling surface with a small indent. Mechanical fixation is also performed using the brackets suitable according to the characteristics. True, B. this case The mass of the equipment is not so great that simplifies the workflow. After performing markup, the wizard installs the anchor elements and, if necessary, crucial profiles. Next, an internal air conditioner unit is installed with a clear observance of horizontal position. Also, some models of such segments according to the instructions should have a small bias towards the passage of drainage.

Maintenance and care

In the standard operation mode, the air conditioner must be serviceed every six months. Most of The works are performed precisely with the external unit that is most susceptible to pollution. Experts typically check the condition of filters, the refrigerant level, the operating pressure of the module's highway, etc. The most difficult operation is the replacement of the working fluid. The refrigerant refers to chemically unsafe substances, so his refueling is better to trust experimental masters. But care for the other components is quite accessible and ordinary users. For example, it is quite simple to answer the question of how to clean the external air conditioner unit. First of all, it should be disassembled, after which, with the help of a vehicle or a vacuum cleaner, to save the inner surface of the module from dust and dirt raids. In the process of such a care, outer filters and heat exchange radiators are cleaned, which extends the service life of the air conditioner.

External block in multi-systems

The concept of the technical implementation of the split system provides for the possibility of using several internal modules in one complex, which are served by one outer block. In contrast to standard configurations, the external module of such a system has engineering differences. To integrate into the multi-system, it is equipped with an additional thermostat that allows you to efficiently control the fan and compressor settings. In turn, the internal unit of the air conditioner acts as a source of information signals that determine the control of the outer module. That is, the user using the remote control refers to the panel of the indoor unit, and the one, in turn, digital canal Regulates the system of overhead communications on the freon highway.

Question price

In modern modifications, air conditioners such as split-systems are not suiced, which is largely due to the complexity of the design. Even in the initial segment, the cost of the air conditioner with the removal unit is rarely less than 20 thousand rubles. Of course, you can find options for 15 thousand rubles. From little-known brands, but their quality is doubts about specialists, and the users themselves often complain about malfunctions.

Decent models offer Fujitsu, Daikin, Mitsubishi, etc. average cost The air conditioner from the data range of firms varies in the range of 30-40 thousand rubles. At the same time, the most technological and productive kits may be estimated at 70-80 thousand rubles.

Conclusion

The use of air conditioners with a design involving the installation of the remote block gives a lot of problems during installation and further maintenance. And this is excluding difficulties in the transportation of equipment. These factors allow us to talk about such aggregates as morally obsolete. Especially against the background of the spread of mobile devices with modest sizes. However, the external air conditioner unit retains its relevance on the market. It is explained by its high performance, functionality and safety during operation, since the main working components are outside the residential premises. And if for household use You can find a low-power replacement of a split system in the form of a monoblock, then in the context of the maintenance office premises, public buildings and institutions multifunctional complexes are still not equal.

The power consumption of split systems is determined by two factors: cooling / heating time and compressor rotation frequency. In the case of inverter, the compressor operates at one speed, the speed of the compressor remains unchanged throughout the entire work until the machine is turned off. Power consumption is determined by the time of the device in the clock, multiplied by its power.

The power consumption of inverter split systems can be monitored in real time, comparing the temperature of the thermostat and reduce the frequency of rotation of the compressor, thereby reducing energy consumption immediately.

Household air conditioners are equipped with EER rating. Eer means Energy Efficiency Ratio. EER is the ratio of cooling power to power consumed. Thus, 24,000 BTU split with Eer 10 consumes 2400 W (24000/2400). Air conditioners with Eer 10 and higher are very common in the market, so Kuban Comfort does not recommend purchasing blocks with EER less than 10.

Because of the exceptionally high power consumed air conditioners, they are striving to do with the EER rating above 11. Such models are easy to find.

Influence of block size on consumption. Air conditioners and power.

In some cases, very large blocks have a little lower EER (this means that they use more energy) than the average blocks. However, small air conditioners may end up exit for you more expensive. Small split systems or air conditioners for cooling rooms work longer, and sometimes without stopping. In order to avoid permanent operation of small devices, people often buy larger units (9000 BTU for 20 square meters of room, for example). It is worth considering the shadow and sunny strand of the building if the room is on sunny side, It is worth taking split more powerful, the shadow - suitable (7000 BTU for 20 square meters of the room, for example).

The power consumption of air conditioners and the block size (ERR is calculated relative to the BTU indicators, and not kW).

Split system and air conditioning 5000 BTU (5)

5000 BTU (Five) Air conditioners are not the smallest on the market, but they are rare and Kuban comfort does not recommend them. 5000 BTU air conditioners or splits are recommended for rooms less than 20 square meters (ideally less than 15 square meters). Most often "five" do not have functions of heating, but only cooling, consider it.
For rooms up to 24 square meters, 7000-8000 BTU split (seven, eight) suitable.
The power consumption is 5000 BTU air conditioning on average from 446 to 580 W (statistics more on the window, since the splits of such power are rarity).

Split systems and air conditioners 7000 BTU (7)

7000 BTU Split system (seven), most popular in Russia, most often intended for rooms 20-25 square meters, if you take on large squarethen expected more high flow Electricity and approximately 15-25% reduced service life (for example, for 25-35 square meters).
Power consumption 7000 BTU air conditioners (split) ranges from 600-800 W. Also, read the difference in the cheap and more expensive air conditioner.

Split systems and air conditioners 9000 BTU (9)

Power consumption 9000 BTU air conditioners ranges from 800-900 W (if 9000 BTU block consumes more than 900 W, it is ineffective and you better find another model). Splits of nine are recommended for rooms with an area of \u200b\u200b26-35 square meters (this average applies to the window and split system).
If you are interested in buying a 9000 BTU block for 35-40 square meters, you better look at the 12000 BTU splits, as they will cool your room faster and better. They will consume less energyThe smaller units because they will not work constantly, the smaller (in this case, Kuban Comfort means inverter).
You can find air conditioning with the highest EER, call us and we will tell you the most effective.

Split system and air conditioners 12000 BTU (12)

12000 BTU Split system consumes from 1061 (Eer: 11.3) to 1333 W (Eer: 9, which is a bit low to today's standards). Eer 11.3 medium for modern splits 12000 BTU, translating 1061 W. Do not buy less than 11.3 (in other words, do not buy with consumption over 1061 watts). Splits with Eer 11.3 are so frequent that you will not have any problems with their search. Your wallet will be grateful to you later.
12000 BTUs are recommended for rooms, ranging from 35 to 50 square meters.

Split system and air conditioners 18000 BTU (18)

Split systems and air conditioners 24000 BTU (24)

24 000 BTU Split is slightly less effective than their smaller counterparts, with an EER range from 8.5 to 9.6 for modern blocks. They usually consume from 2500 to 2823 watts. Despite their relatively low efficiency, these units are one of the most widely used because they cooled the rooms very quickly. For this reason, they are still a good option.

In Russia, the capacity consumption of 24,000 BTU household air conditioner is on average 228 kW / h per month, and these blocks are recommended for premises, ranging from 72 to 120 square meters, but it is not mandatory requirement. These devices can be used in small rooms.

Reducing electricity during air conditioning. Use, Cooling on the budget.

After viewing the data on power consumption above, you can be concerned about the high use of air conditioners energy, but do not worry, Kuban Comfort will tell how to save.

Service

Air conditioners must pass the air through a variety of tiny cells in order to work efficiently. Make sure that the filters are clean, as well as cells of the condenser and evaporator. If any of the listed attributes are dirty, cooling will be low-quality.

The scored capacitor with an insufficient air flow can lead to overheating, reducing its ability to dispel heat outside (efficiency decreases), as well as damage the compressor. The dirty evaporator can freeze, which significantly reduces efficiency and rendering. The same applies to filters. No longer cleaned, call the wizard for cleaning.

Use white curtains

White curtains can reflect a significant amount of hot sunlight back out. sunlight turns into heat after it enters your room.

The difference is cheap from more expensive split systems

What do they differ and is it worth overpaying? Cheap splits are cheaper due to the use of a thinner metal in tubes and radiators, due to cheaper electronics, plastic and due to a cheaper compressor. Now in order: Electronics in this case has the least discrepancy with expensive models and is about 2-3 years of the difference in the operation of this block, the electronics are expensive in expensive splits longer. Next, we have a compressor, today even cheap compressors make a qualitative and difference in terms of the same as the electronics. Cheap plastic turns yellow, no expensive. But the use of fine metal will lead to more frequent leaks and require more frequent maintenance. Kuban Comfort recommends buying more expensive and famous brandsFrom which you will enjoy.

During the operation of the household split system you can feel nasty smell rot together with air flows from the device. He indicates the need preventive cleansing Block. In addition to repulsive amber, the clogging of nodes can cause the rapid wear of the power part, an increased consumption of electricity and the occurrence of allergic reactions in humans.

Perform this procedure can be entrusted to the employee service Center. But if you use a split system for a long time, you can cope with the works yourself, saving money. It is only necessary to familiarize yourself with the procedure for disassembling and conducting preventive cleaning.

Dimensions of the inner block

Before installing the internal unit of the air conditioner, you must ask him with sizes. This is especially important when repairing, because modern technologies Quite often include the installation of suspended ceiling systems that can affect the height of the ceiling, as well as the parameters of the device described.

You can find non-standard models that have unique sizes. The block length is usually varied from 700 to 800 mm. Several less often are products up to 900 mm. Experts recommend to take into account in the middle length of 770 mm.

As for height, it is usually 250-290 mm. Averaged value is 270 mm. The depth is not much interested in consumers, but it reaches 240 mm. The minimum value is equivalent to 170 mm. From this we can conclude that the average sizes of the indoor unit of the air conditioner are 770 x 270 mm.

Knowing these parameters allows you to determine at what distance from the ceiling and walls to hang equipment. The contradictions on this issue are a great set. In some instructions minimum distance It is 50 mm, whereas in others it reaches 300 mm. The optimal value is equal to a digit from 60 to 150 mm.

Experts are usually installed air conditioning with 100 mm remoteness. Before mounting the indoor unit of the air conditioner, it is important to consider whether the curtains will be indoors. The step between them and the split system is usually 150 mm. You can increase this value up to 250 mm. The average distance from the block to the wall is 400 mm.

Classification of internal blocks

In order to disassemble, it is necessary to determine the type of the inner unit of the air conditioner, which can be presented:

• wall split system;
• channel air conditioning;
• cassette device.

The most common are wall-mounted models that are more accessible at cost and are sometimes called domestic. Its installation can be carried out in the room of any destination, and the power within 7 kW allows you to cool up to 70 m 2 area. Such blocks are usually installed in the upper part of the wall, close to the window, as the design involves the presence of an outer unit, and the nodes must be interconnected.

Wall-mounted air conditioners are not able to serve fresh air, as this requires a separate ventilation system. If you wondered how to disassemble the internal unit of the air conditioner, you can read this information below. It is for such a device that recommendations are provided in the article.

In addition to household air conditioners, some manufacturers deliver the semi-industrial instruments to the market, the power of which reaches 10 kW. Externally, they come to traditional split systems, but by parameters are semi industrial equipment.

Channel air conditioners are installed with suspended ceilings that hide them completely. The chilled air distribution is provided by heat-insulated ducts, which are located in the interporal space. Such structures can cool several rooms at once. The capacity of the equipment reaches 25 kW, which allows to ensure the cooling of the cottage or several rooms of the apartment. As the main feature channel systems It is possible to feed fresh air In volume that is guaranteed by the functioning of full ventilation.

Cassette air conditioners require a suspended ceiling when mounting. When compared with channel structures, cassette distribute cooled air through the bottom of the block. It closes with a decorative lattice and usually has the following dimensions: 600 x 600 and 1200 x 600 mm.

Demolition and cleaning conditioner

To clean the indoor unit of the air conditioner, it is necessary to make it disassembly. For this, screwdrivers are prepared different configuration and sizes. You should take care of the presence of a box for collecting fasteners. It will take the electrical and functional diagram of the device. In some models, they are applied to inner side top cover.

To clean the internal elements, you will need:

• pure rag;
• detergent;
• a vacuum cleaner.

At the first stage, it is necessary to make air conditioning. This corresponds to the rules of electrical safety. You should remove the plug from the outlet. The top cover of the block is removed. Unscrew bolts that can be two or three. Usually they are closed with decorative plugs. The top cover of the inner block is extracted. If it is covered with a layer of mold and dirt, it should be washed into the bathroom with detergents And brushes.

Viewing the internal air conditioner unit, you will need to remove air filters. They are made of plastic and are designed for coarse air purification. Sometimes they are fixed on the lid or inside the air conditioner. Filters are washed under an intensive jet of water. This will help the brush.

Airflow guides should also be removed. Blinds are extracted from the grooves. To facilitate the process, it is necessary to be slightly bend them. These elements guide the flow of cold air inside the room and also need a reinforced flushing.

Dismantling bottom cover

The next step will be the disconnection of the bottom cover. It will be necessary to remove the drainage tube and the power supply wire. In the process of this, three latches should be squeezed and disconnect the drain bath from the block along with the output hose.

Extract terminal blocks

The internal unit of the air conditioner has terminal blocks. They are disconnected in the process of disassembly, and after the electronic control unit and the transformer are removed. In order to remove the first, it is necessary to squeeze the side mounts, and after pulling the device on yourself. Before this ground wires are unscrewed.

Eat engine fan

Now you can dismantle the fan engine. To do this, bolts are unscrewed that are strengthened to the chassis. The evaporator is lifted, and the engine is extracted with a rotary fan. Motor must be separated from the fan, but first you have to warm up the head of the bolt with a soldering iron. This will unlock the thermal lock on the motor pulley. As soon as the fan blades can be removed, they must be washed. The assembly is carried out in reverse order.

Cleaning an external block

External and internal blocks of air conditioners equally need maintenance. The frequency for the first is twice a year, which is true even with intensive operation. It is necessary to use a vacuum cleaner for this, but the device must be quite powerful to pull the dust from the outer filters and heat exchange radiators.

Independently or with the help of specialists

If the block is located on an impressive height, then you can unscrew the protective grille and spending it, as well as wipe the insides from dust. Otherwise, you can seek help from professionals that will remove air conditioning using climbing equipment or tower. Cleaning yourself can be done with the help of compact sedents, but the air conditioning system will have to be de-energized and turned on only 30 minutes after the end of the maintenance.

Finally

During the operation of the split system, dust settles on the impeller of the fan, where the "fur coat" is formed. This prevents the passage of air flow when blowing the evaporator. The latter is frozen, and the user does not receive a normal cold and intensive air flow.

Cleaning the fan of the indoor unit of the air conditioner is required in the case when you saw black flakes flying out of the device. This suggests that the amount of dirt is so great that it is not held on the internal nodes. As prevention from time to time you can dismantle the fan and wash it chemicals. But not all models make it easy to extract this part of the system.

Often, during repair, many think about the installation of the split system and plan the design of the room under the size of the air conditioner. The internal unit of this device must be placed in such a way that it is not only correctly located, but also the most harmoniously looked in the intentional interior.

The acquisition and selection of the air conditioner itself is often planned closer to the end of the repair, but also to supply "food" is already needed. So for such cases, this article is written. In it, we will consider in detail what distances should be taken into account for subsequent installation, and reveal the most universal dimensions of the internal blocks (wall household devices).

At first, we immediately want to warn that there are "non-standard" models of air conditioners that may have unique sizes and characteristics. And therefore this article should not be perceived as 100% universal.

Air conditioner size. Internal split system unit

Most often residential Rooms have small square (up to 25 mpq.) For such premises, conditioners are suitable for up to 2.7 kW (not confusing with power consumed) - usually they are called "Sevenki" or "Nine". As a rule, "seven" and "nine" (one and the same model) have the same dimensions, as well as the same diameter of the tubes. Therefore, we will further take into account the same dimensions and characteristics of the considered sizes.

The overall dimensions of the indoor block that we are interested in first

• block length. The most standard length of the internal blocks is 700-800 mm. A little less common up to 900 mm. By personal experience The cost is best to take an average length of 770 mm.
• block height. Most often, these sizes are in the range of 250-290 mm. For planning we will take into account 270 mm.

Depths of us are not very interested in (170-240 mm). Thus, we revealed averaged internal unit size 770 x 270 mm.

Distances from the walls and ceiling

1. ON / OFF air conditioners. The cable is displayed in such a way that it is subsequently located under internal block (left for 300 mm. and below 100 mm. From the center of the block).
2. In the majority
