ADOPTION OF NEW REFRIGERANT

This Air Conditioner is a new type which adopts a new refrigerant HFC (R410A) instead of the conventional refrigerant R22 in order to prevent destruction of the ozone layer.

WARNING

Cleaning of the air filter and other parts of the air filter involves dangerous work in high places, so be sure to have a service person do it. Do not attempt it yourself. The cleaning diagram for the air filter is there for the service person, and not for the customer.

NOTE

A direct current motor is adopted for indoor fan motor in the Concealed Duct Standard Type air conditioner.

Caused from its characteristics, a current limit works on the direct current motor. When replacing the highperformance filter or when opening the service board, be sure to stop the fan. If an above action is executed during the fan operation, the protective control works to stop the unit operation, and the check code “P12” may be issued. However it is not a trouble. When the desired operation has finished, be sure to reset the system to clear “P12” error code using the leak breaker of the indoor unit. Then push the operation stop button of the remote controller to return to the usual operation.

Check earth wires.

WARNING

Before troubleshooting or repair work, check the earth wire is connected to the earth terminals of the main unit, otherwise an electric shock is caused when a leak occurs.

If the earth wire is not correctly connected, contact an electric engineer for rework.

Do not modify the products.

Do not also disassemble or modify the parts. It may cause a fire, electric shock or injury.

Prohibition of modification.

Use specified parts.

Do not bring a child close to the equipment.

For spare parts, use those specified (

∗∗∗∗∗

).

If unspecified parts are used, a fire or electric shock may be caused.

∗

: For details, refer to the parts list.

Before troubleshooting or repair work, do not bring a third party (a child, etc.) except the repair engineers close to the equipment.

It causes an injury with tools or disassembled parts.

Please inform the users so that the third party (a child, etc.) does not approach the equipment.

Connect the cut-off lead cables with crimp contact, etc, put the closed end side upward and then apply a water-cut method, otherwise a leak or production of fire is caused at the users’ side.

Insulating measures

No fire

Refrigerant

Assembly/Cabling

When repairing the refrigerating cycle, take the following measures.

1) Be attentive to fire around the cycle. When using a gas stove, etc, be sure to put out fire before work; otherwise the oil mixed with refrigerant gas may catch fire.

2) Do not use a welder in the closed room. When using it without ventilation, carbon monoxide poisoning may be caused.

3) Do not bring inflammables close to the refrigerant cycle, otherwise fire of the welder may catch the inflammables.

Check the used refrigerant name and use tools and materials of the parts which match with it.

For the products which use R410A refrigerant, the refrigerant name is indicated at a position on the outdoor unit where is easy to see. To prevent miss-charging, the route of the service port is changed from one of the former R22.

For an air conditioner which uses R410A, never use other refrigerant than R410A.

For an air conditioner which uses other refrigerant (R22, etc.), never use R410A.

If different types of refrigerant are mixed, abnormal high pressure generates in the refrigerating cycle and an injury due to breakage may be caused.

Do not charge refrigerant additionally.

If charging refrigerant additionally when refrigerant gas leaks, the refrigerant composition in the refrigerating cycle changes resulted in change of air conditioner characteristics or refrigerant over the specified standard amount is charged and an abnormal high pressure is applied to the inside of the refrigerating cycle resulted in cause of breakage or injury.

Therefore if the refrigerant gas leaks, recover the refrigerant in the air conditioner, execute vacuuming, and then newly recharge the specified amount of liquid refrigerant. In this time, never charge the refrigerant over the specified amount.

When recharging the refrigerant in the refrigerating cycle, do not mix the refrigerant or air other than R410A into the specified refrigerant.

If air or others is mixed with the refrigerant, abnormal high pressure generates in the refrigerating cycle resulted in cause of injury due to breakage.

After installation work, check the refrigerant gas does not leak.

If the refrigerant gas leaks in the room, poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.

Never recover the refrigerant into the outdoor unit.

When the equipment is moved or repaired, be sure to recover the refrigerant with recovering device. The refrigerant cannot be recovered in the outdoor unit; otherwise a serious accident such as breakage or injury is caused.

After repair work, surely assemble the disassembled parts, and connect and lead the removed cables as before. Perform the work so that the cabinet or panel does not catch the inner cables.

If incorrect assembly or incorrect cable connection was done, a disaster such as a leak or fire is caused at user’s side.

– 5 –



Insulator check

Ventilation

WARNING

After the work has finished, be sure to use an insulation tester set (500V mugger) to check the resistance is 2M

Ω

or more between the charge section and the non-charge metal section (Earth position).

If the resistance value is low, a disaster such as a leak or electric shock is caused at user’s side.

When the refrigerant gas leaks during work, execute ventilation.

If the refrigerant gas touches to a fire, poisonous gas generates. A case of leakage of the refrigerant and the closed room full with gas is dangerous because a shortage of oxygen occurs. Be sure to execute ventilation.

When checking the circuit inevitably under condition of the power-ON, use rubber gloves and others not to touch to the charging section.

If touching to the charging section, an electric shock may be caused.

Be attentive to electric shock

Compulsion

Check after rerair

Check after reinstallation

When the refrigerant gas leaks, find up the leaked position and repair it surely.

If the leaked position cannot be found up and the repair work is interrupted, pump-down and tighten the service valve, otherwise the refrigerant gas may leak into the room.

The poisonous gas generates when gas touches to fire such as fan heater, stove or cocking stove though the refrigerant gas itself is innocuous.

When installing equipment which includes a large amount of charged refrigerant such as a multi air conditioner in a sub-room, it is necessary that the density does not the limit even if the refrigerant leaks.

If the refrigerant leaks and exceeds the limit density, an accident of shortage of oxygen is caused.

For the installation/moving/reinstallation work, follow to the Installation Manual.

If an incorrect installation is done, a trouble of the refrigerating cycle, water leak, electric shock or fire is caused.

After repair work has finished, check there is no trouble.

If check is not executed, a fire, electric shock or injury may be caused. For a check, turn off the power breaker.

After repair work (installation of front panel and cabinet) has finished, execute a test run to check there is no generation of smoke or abnormal sound.

If check is not executed, a fire or an electric shock is caused. Before test run, install the front panel and cabinet.

Check the following items after reinstallation.

1) The earth wire is correctly connected.

2) The power cord is not caught in the product.

3) There is no inclination or unsteadiness and the installation is stable.

If check is not executed, a fire, an electric shock or an injury is caused.

Put on gloves

Cooling check

CAUTION

Be sure to put on gloves (

∗∗∗∗∗

) during repair work.

If not putting on gloves, an injury may be caused with the parts, etc.

(

∗

) Heavy gloves such as work gloves

When the power was turned on, start to work after the equipment has been sufficiently cooled.

As temperature of the compressor pipes and others became high due to cooling/heating operation, a burn may be caused.

• New Refrigerant (R410A)

This air conditioner adopts a new HFC type refrigerant (R410A) which does not deplete the ozone layer.

1. Safety Caution Concerned to New Refrigerant

The pressure of R410A is high 1.6 times of that of the former refrigerant (R22). Accompanied with change of refrigerant, the refrigerating oil has been also changed. Therefore, be sure that water, dust, the former refrigerant or the former refrigerating oil is not mixed into the refrigerating cycle of the air conditioner with new refrigerant during installation work or service work. If an incorrect work or incorrect service is performed, there is a possibility to cause a serious accident. Use the tools and materials exclusive to R410A to purpose a safe work.

2. Cautions on Installation/Service

1) Do not mix the other refrigerant or refrigerating oil.

For the tools exclusive to R410A, shapes of all the joints including the service port differ from those of the former refrigerant in order to prevent mixture of them.

2) As the use pressure of the new refrigerant is high, use material thickness of the pipe and tools which are specified for R410A.

3) In the installation time, use clean pipe materials and work with great attention so that water and others do not mix in because pipes are affected by impurities such as water, oxide scales, oil, etc. Use the clean pipes.

Be sure to brazing with flowing nitrogen gas. (Never use gas other than nitrogen gas.)

4) For the earth protection, use a vacuum pump for air purge.

5) R410A refrigerant is azeotropic mixture type refrigerant. Therefore use liquid type to charge the refrigerant. (If using gas for charging, composition of the refrigerant changes and then characteristics of the air conditioner change.)

3. Pipe Materials

For the refrigerant pipes, copper pipe and joints are mainly used. It is necessary to select the most appropriate pipes to conform to the standard. Use clean material in which impurities adhere inside of pipe or joint to a minimum.

1) Copper pipe

<Piping>

The pipe thickness, flare finishing size, flare nut and others differ according to a refrigerant type.

When using a long copper pipe for R410A, it is recommended to select “Copper or copper-base pipe without seam” and one with bonded oil amount 40mg/10m or less. Also do not use crushed, deformed, discolored

(especially inside) pipes. (Impurities cause clogging of expansion valves and capillary tubes.)

<Flare nut>

Use the flare nuts which are attached to the air conditioner unit.

2) Joint

The flare joint and socket joint are used for joints of the copper pipe. The joints are rarely used for installation of the air conditioner. However clear impurities when using them.

4. Tools

1. Required Tools for R410A

Mixing of different types of oil may cause a trouble such as generation of sludge, clogging of capillary, etc.

Accordingly, the tools to be used are classified into the following three types.

1) Tools exclusive for R410A (Those which cannot be used for conventional refrigerant (R22))

2) Tools exclusive for R410A, but can be also used for conventional refrigerant (R22)

3) Tools commonly used for R410A and for conventional refrigerant (R22)

The table below shows the tools exclusive for R410A and their interchangeability.

7. REFRIGERANT R410A

This air conditioner adopts the new refrigerant HFC

(R410A) which does not damage the ozone layer.

The working pressure of the new refrigerant R410A is 1.6 times higher than conventional refrigerant

(R22). The refrigerating oil is also changed in accordance with change of refrigerant, so be careful that water, dust, and existing refrigerant or refrigerating oil are not entered in the refrigerant cycle of the air conditioner using the new refrigerant during installation work or servicing time.

The next section describes the precautions for air conditioner using the new refrigerant. Conforming to contents of the next section together with the general cautions included in this manual, perform the correct and safe work.

6. When an air conditioning system charged with a large volume of refrigerant is installed in a small room, it is necessary to exercise care so that, even when refrigerant leaks, its concentration does not exceed the marginal level.

If the refrigerant gas leakage occurs and its concentration exceeds the marginal level, an oxygen starvation accident may result.

7. Be sure to carry out installation or removal according to the installation manual.

Improper installation may cause refrigeration trouble, water leakage, electric shock, fire, etc.

8. Unauthorized modifications to the air conditioner may be dangerous. If a breakdown occurs please call a qualified air conditioner technician or electrician.

Improper repair’s may result in water leakage, electric shock and fire, etc.

7-1. Safety During Installation/Servicing

As R410A’s pressure is about 1.6 times higher than that of R22, improper installation/servicing may cause a serious trouble. By using tools and materials exclusive for R410A, it is necessary to carry out installation/servicing safely while taking the following precautions into consideration.

1. Never use refrigerant other than R410A in an air conditioner which is designed to operate with

R410A.

If other refrigerant than R410A is mixed, pressure in the refrigeration cycle becomes abnormally high, and it may cause personal injury, etc. by a rupture.

2. Confirm the used refrigerant name, and use tools and materials exclusive for the refrigerant R410A.

The refrigerant name R410A is indicated on the visible place of the outdoor unit of the air conditioner using R410A as refrigerant. To prevent mischarging, the diameter of the service port differs from that of R22.

3. If a refrigeration gas leakage occurs during installation/servicing, be sure to ventilate fully.

If the refrigerant gas comes into contact with fire, a poisonous gas may occur.

4. When installing or removing an air conditioner, do not allow air or moisture to remain in the refrigeration cycle. Otherwise, pressure in the refrigeration cycle may become abnormally high so that a rupture or personal injury may be caused.

5. After completion of installation work, check to make sure that there is no refrigeration gas leakage.

If the refrigerant gas leaks into the room, coming into contact with fire in the fan-driven heater, space heater, etc., a poisonous gas may occur.

7-2. Refrigerant Piping Installation

7-2-1. Piping Materials and Joints Used

For the refrigerant piping installation, copper pipes and joints are mainly used. Copper pipes and joints suitable for the refrigerant must be chosen and installed. Furthermore, it is necessary to use clean copper pipes and joints whose interior surfaces are less affected by contaminants.

1. Copper Pipes

It is necessary to use seamless copper pipes which are made of either copper or copper alloy and it is desirable that the amount of residual oil is less than 40 mg/10 m. Do not use copper pipes having a collapsed, deformed or discolored portion (especially on the interior surface).

Otherwise, the expansion valve or capillary tube may become blocked with contaminants.

As an air conditioner using R410A incurs pressure higher than when using R22, it is necessary to choose adequate materials.

Thicknesses of copper pipes used with R410A are as shown in Table 7-2-1. Never use copper pipes thinner than 0.8 mm even when it is available on the market.

For copper pipes, flare joints or socket joints are used. Prior to use, be sure to remove all contaminants.

a) Flare Joints

Flare joints used to connect the copper pipes cannot be used for pipings whose outer diameter exceeds

20 mm. In such a case, socket joints can be used.

Sizes of flare pipe ends, flare joint ends and flare nuts are as shown in Tables 7-2-3 to 7-2-6 below.

b) Socket Joints

Socket joints are such that they are brazed for connections, and used mainly for thick pipings whose diameter is larger than 20 mm. Thicknesses of socket joints are as shown in Table 7-2-2.

7-2-2. Processing of Piping Materials

When performing the refrigerant piping installation, care should be taken to ensure that water or dust does not enter the pipe interior, that no other oil other than lubricating oils used in the installed air conditioner is used, and that refrigerant does not leak. When using lubricating oils in the piping processing, use such lubricating oils whose water content has been removed. When stored, be sure to seal the container with an airtight cap or any other cover.

1. Flare Processing Procedures and Precautions a) Cutting the Pipe

By means of a pipe cutter, slowly cut the pipe so that it is not deformed.

b) Removing Burrs and Chips

If the flared section has chips or burrs, refrigerant leakage may occur.

Carefully remove all burrs and clean the cut surface before installation.

Make certain that a clamp bar and copper pipe have been cleaned.

By means of the clamp bar, perform the flare processing correctly.

Use either a flare tool for R410A or conventional flare tool.

Flare processing dimensions differ according to the type of flare tool.

When using a conventional flare tool, be sure to secure “dimension A” by using a gauge for size adjustment.

2. Flare Connecting Procedures and Precautions a) Make sure that the flare and union portions do not have any scar or dust, etc.

b) Correctly align the processed flare surface with the union axis.

c) Tighten the flare with designated torque by means of a torque wrench. The tightening torque for R410A is the same as that for conventional R22. Incidentally, when the torque is weak, the gas leakage may occur.

When it is strong, the flare nut may crack and may be made non-removable. When choosing the tightening torque, comply with values designated by manufacturers. Table 7-2-7 shows reference values.

NOTE:

When applying oil to the flare surface, be sure to use oil designated by the manufacturer. If any other oil is used, the lubricating oils may deteriorate and cause the compressor to burn out.

7-4. Recharging of Refrigerant

When it is necessary to recharge refrigerant, charge the specified amount of new refrigerant according to the following steps.

Recover the refrigerant, and check no refrigerant remains in the equipment.

Connect the charge hose to packed valve service port at the outdoor unit’s gas side.

When the compound gauge’s pointer has indicated

–0.1 Mpa (–76 cmHg), place the handle Low in the fully closed position, and turn off the vacuum pump’s power switch.

Connect the charge hose of the vacuum pump adapter.

Keep the status as it is for 1 to 2 minutes, and ensure that the compound gauge’s pointer does not return.

Open fully both packed valves at liquid and gas sides.

Set the refrigerant cylinder to the electronic balance, connect the connecting hose to the cylinder and the connecting port of the electronic balance, and charge

liquid refrigerant.

(For refrigerant charging, see the figure below.)

Place the handle of the gauge manifold Low in the fully opened position, and turn on the vacuum pump’s power switch. Then, evacuating the refrigerant in the cycle.

1) Never charge refrigerant exceeding the specified amount.

2) If the specified amount of refrigerant cannot be charged, charge refrigerant bit by bit in COOL mode.

3) Do not carry out additional charging.

When additional charging is carried out if refrigerant leaks, the refrigerant composition changes in the refrigeration cycle, that is characteristics of the air conditioner changes, refrigerant exceeding the specified amount is charged, and working pressure in the refrigeration cycle becomes abnormally high pressure, and may cause a rupture or personal injury.

1) Be sure to make setting so that liquid can be charged.

2) When using a cylinder equipped with a siphon, liquid can be charged without turning it upside down.

It is necessary for charging refrigerant under condition of liquid because R410A is mixed type of refrigerant.

Accordingly, when charging refrigerant from the refrigerant cylinder to the equipment, charge it turning the cylinder upside down if cylinder is not equipped with siphon.

7-5. Brazing of Pipes

7-5-1. Materials for Brazing

1. Silver brazing filler

Silver brazing filler is an alloy mainly composed of silver and copper. It is used to join iron, copper or copper alloy, and is relatively expensive though it excels in solderability.

2. Phosphor bronze brazing filler

Phosphor bronze brazing filler is generally used to join copper or copper alloy.

3. Low temperature brazing filler

Low temperature brazing filler is generally called solder, and is an alloy of tin and lead. Since it is weak in adhesive strength, do not use it for refrigerant pipes.

1) Phosphor bronze brazing filler tends to react with sulfur and produce a fragile compound water solution, which may cause a gas leakage. Therefore, use any other type of brazing filler at a hot spring resort, etc., and coat the surface with a paint.

2) When performing brazing again at time of servicing, use the same type of brazing filler.

7-5-2. Flux

1. Reason why flux is necessary

• By removing the oxide film and any foreign matter on the metal surface, it assists the flow of brazing filler.

• In the brazing process, it prevents the metal surface from being oxidized.

• By reducing the brazing filler's surface tension, the brazing filler adheres better to the treated metal.

– 56 –



2. Characteristics required for flux

• Activated temperature of flux coincides with the brazing temperature.

• Due to a wide effective temperature range, flux is hard to carbonize.

• It is easy to remove slag after brazing.

• The corrosive action to the treated metal and brazing filler is minimum.

• It excels in coating performance and is harmless to the human body.

As the flux works in a complicated manner as described above, it is necessary to select an adequate type of flux according to the type and shape of treated metal, type of brazing filler and brazing method, etc.

3. Types of flux

• Noncorrosive flux

Generally, it is a compound of borax and boric acid.

It is effective in case where the brazing temperature is higher than 800°C.

• Activated flux

Most of fluxes generally used for silver brazing are this type.

It features an increased oxide film removing capability due to the addition of compounds such as potassium fluoride, potassium chloride and sodium fluoride to the borax-boric acid compound.

7-5-3. Brazing

As brazing work requires sophisticated techniques, experiences based upon a theoretical knowledge, it must be performed by a person qualified.

In order to prevent the oxide film from occurring in the pipe interior during brazing, it is effective to proceed with brazing while letting dry Nitrogen gas flow.

Never use gas other than Nitrogen gas.

1. Brazing method to prevent oxidation

1) Attach a reducing valve and a flow-meter to the Nitrogen gas cylinder.

2) Use a copper pipe to direct the piping material, and attach a flow-meter to the cylinder.

3) Apply a seal onto the clearance between the piping material and inserted copper pipe for

Nitrogen in order to prevent backflow of the

Nitrogen gas.

4) When the Nitrogen gas is flowing, be sure to keep the piping end open.

5) Adjust the flow rate of Nitrogen gas so that it is lower than 0.05 m³/Hr or 0.02 MPa

(0.2kgf/cm²) by means of the reducing valve.

6) After performing the steps above, keep the

Nitrogen gas flowing until the pipe cools down to a certain extent (temperature at which pipes are touchable with hands).

7) Remove the flux completely after brazing.

M

Flow meter

Stop valve

Nitrogen gas cylinder

From Nitrogen cylinder

1) Do not enter flux into the refrigeration cycle.

2) When chlorine contained in the flux remains within the pipe, the lubricating oil deteriorates.

Therefore, use a flux which does not contain chlorine.

3) When adding water to the flux, use water which does not contain chlorine (e.g. distilled water or ion-exchange water).

4) Remove the flux after brazing.

Freeze preventive control

(Low temperature release)

Outline of specifications Remarks

1) The cooling operation (including Dry operation) is performed as follows based on the detected temperature of Tc sensor or Tcj sensor.

When [J] zone is detected for 6 minutes (Following figure), the commanded frequency is decreased from the real operation frequency. After then the commanded frequency changes every 30 seconds while operation is performed in [J] zone.

In [K] zone, time counting is interrupted and the operation is held.

When [I] zone is detected, the timer is cleared and the operation returns to the normal operation.

If the commanded frequency becomes S0 because the operation continues in [J] zone, the return temperature

A is raised from 5°C to 12°C until [I] zone is detected and the indoor fan operates with [M] mode.

9. CIRCUIT CONFIGURATION AND CONTROL SPECIFICATIONS

9-1. Indoor Control Circuit

9-1-1. Outline of Main Controls


1. Pulse Motor Valve (P.M.V.) control

1) PMV is controlled with 50 to 500 pulses during operation, respectively.

2) In cooling operation, P.M.V. is controlled with the temperature difference between TS sensor and TC sensor.

3) In heating operation, P.M.V. is controlled with the temperature difference between TS sensor and TE sensor.

4) For the temperature difference in items 2) and 3), 1 to 5K is aimed as the target in both cooling and heating operations.

5) When the cycle excessively rose in both cooling and heating operations, PMV is controlled by TD sensor.

The aimed value is usually 105°C for SM562 and 100°C for SM802, SM1102, SM1402 in both cooling and heating operations.

REQUIREMENT

A sensor trouble may cause a liquid back-flow or abnormal overheat resulting in excessive shortening of the compressor life. In a case of trouble on the compressor, be sure to check there is no error in the resistance value an the refrigerating cycle of each sensor after repair and then start the operation.

2. Discharge temperature release control

1) This function controls the operation frequency, that is, lowers the operation frequency when the discharge temperature has not lower or the discharge temperature has rapidly risen during P.M.V. control.

It subdivides the frequency control up to a unit of

0.6Hz to stabilize the cycle.

2) When the discharge temperature is detected in an abnormal stop zone, the unit stops the compressor and restarts after 2 minutes 30 seconds.

The error counter is cleared when it has continued the operation for 10 minutes.

If the abnormal stop zone has been detected by 4 times without clearing of counter, an error “P03” is displayed.

* The cause is considered as excessively little amount of refrigerant, defective PMV, or clogging of cycle.

5. Coil heating control

1) This control function heats the compressor by turning on the stopped compressor instead of a case heater. It purposes to prevent slackness of the refrigerant inside of the compressor.

2) As usual, turn on power of the compressor for the specified time before a test run after installation, otherwise a trouble of the compressor may be caused. As same as a test run, it is recommended to turn on power of the compressor beforehand when starting operation after power of the compressor has been interrupted for a long time.

3) A judgment for electricity is performed by TD and TO sensors. If TO sensor is defective, a backup control is automatically performed by TE sensor. For a case of defective TO sensor, judge it with the outdoor LED display.

4) Coil heating is controlled by TD and TE sensor.

5) For every model, the power is turned off when TD is 30°C or more.

Power supply for cord heater

NOTE:

Separate the cord heater power from the air conditioner power, and connect it to its exclusive breaker.

By doing so, the power consumption can be decreased because the breaker can be turned off if there is no possibility of freezing of the base plate in cooling operation, etc.

When the cord heater power is connected to the inverter P.C. board assembly or others without connected to the exclusive breaker, the control P.C. board of the inverter assembly may cause a failure.

When the cord heater has been mounted on a base plate, do not mount the water-proof cap and drain nipple which are provided with the outdoor unit on the base plate.

Cord heater installation work

Drill a hole on the outdoor unit base plate, and fix the cord heater to the outdoor unit base plate using P-shape clamp.

Connect the cord heater cables.

Using a motor drill, etc., drill Ø3.2 holes on the outdoor unit base plate. (12 positions) See Appendix-10 for the additional hole positions.

These holes are used to fix the cord heater to the outdoor unit base plate with P-shape clamp.

Insert the PVC tube into the cord heater.

This tube is designed to protect the cord heater from the fixing screws used to secure the anchoring feet.

As shown in the left figure, install the cord heater

(1.5m) to the outdoor unit base plate by using Pshape clamp and screws (Self-tapping screw type-B

Ø4 × 6mm, stainless).

Pay attention to the direction of P-shape clamp so that it is set to the same direction in the left figure.

PVC tube

Ø9.1 P-shape clamp

The PVC tube must be inserted into the cord heater between the fixing screws in order to protect the cord heater from these screws.

Under no circumstances must the tube be allowed to ride over the tip of the fixing screws.

* If the drain port is frozen due to installation status, etc., draw around the cord heater so that the end part of the heater is inserted into the drain port. In this case, add some fixing positions to fix the cord heater surely.

* The end part from the marked part of the cord heater heats up. When there is the heating part near the electric parts box, a fire may generate.

Be sure to set the heating part on the outdoor unit base plate at the fan room side or near it.

WARNINGS ON REFRIGERANT LEAKAGE

Check of Concentration Limit

The room in which the air conditioner is to be installed requires a design that in the event of refrigerant gas leaking out, its concentration will not exceed a set limit.

The refrigerant R410A which is used in the air conditioner is safe, without the toxicity or combustibility of ammonia, and is not restricted by laws to be imposed which protect the ozone layer. However, since it contains more than air, it poses the risk of suffocation if its concentration should rise excessively. Suffocation from leakage of R410A is almost non-existent. With the recent increase in the number of high concentration buildings, however, the installation of multi air conditioner systems is on the increase because of the need for effective use of floor space, individual control, energy conservation by curtailing heat and carrying power etc.

Most importantly, the multi air conditioner system is able to replenish a large amount of refrigerant compared with conventional individual air conditioners. If a single unit of the multi conditioner system is to be installed in a small room, select a suitable model and installation procedure so that if the refrigerant accidentally leaks out, its concentration does not reach the limit (and in the event of an emergency, measures can be made before injury can occur).

In a room where the concentration may exceed the limit, create an opening with adjacent rooms, or install mechanical ventilation combined with a gas leak detection device.

The concentration is as given below.

Total amount of refrigerant (kg)

Min. volume of the indoor unit installed room (m³)

≤

Concentration limit (kg/m³)

The concentration limit of R410A which is used in multi air conditioners is 0.3kg/m³.

NOTE 1 :

If there are 2 or more refrigerating systems in a single refrigerating device, the amounts of refrigerant should be as charged in each independent device.

e.g., charged amount (10kg)

Outdoor unit e.g., charged amount (15kg)

Room A Room B Room C Room D Room E Room F

Indoor unit

For the amount of charge in this example:

The possible amount of leaked refrigerant gas in rooms A, B and C is 10kg.

The possible amount of leaked refrigerant gas in rooms D, E and F is 15kg.

Important

NOTE 2 :

The standards for minimum room volume are as follows.

(1) No partition (shaded portion)

(2) When there is an effective opening with the adjacent room for ventilation of leaking refrigerant gas

(opening without a door, or an opening 0.15% or larger than the respective floor spaces at the top or bottom of the door).

Refrigerant piping

Indoor unit

(3) If an indoor unit is installed in each partitioned room and the refrigerant piping is interconnected, the smallest room of course becomes the object. But when a mechanical ventilation is installed interlocked with a gas leakage detector in the smallest room where the density limit is exceeded, the volume of the next smallest room becomes the object.
