FILE NO. SVM-12004

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.

After completing the repair or relocation work, check that the ground wires are connected properly. Be sure to connect earth wire. (Grounding work) Incomplete grounding causes an electric shock.

Do not connect ground wires to gas pipes, water pipes, and lightning rods or ground wires for telephone wires.

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

When any of the electrical parts are to be replaced, ensure that the replacement parts satisfy the specifications given in the Service Manual (or use the parts contained on the parts list in the Service Manual).

Use of any parts which do not satisfy the required specifications may give rise to electric shocks, smoking and/ or a fire.

If, in the course of carrying out repairs, it becomes absolutely necessary to check out the electrical parts with the electrical control box cover of one or more of the indoor units and the service panel of the outdoor unit removed in order to find out exactly where the trouble lies, put a sign in place so that no-one will approach the work location before proceeding with the work. Third-party individuals may enter the work site and receive electric shocks if this warning is not heeded.

Insulating measures

No fire

Refrigerant

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

When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because the oil that coats the pipes may otherwise burn.

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.

The refrigerant used by this air conditioner is the R410A. 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 hig h 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.

repair

FILE NO. SVM-12004

After repair work, surely assemble the disassembled parts, and connect and lead the removed wires as before. Perform the work so that the cabinet or panel does not catch the inner wires. If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or fire is caused at user’s

side.

After the work has finished, be sure to use an insulation tester set (500 V Megger) to check the resistance is 1 MΩ 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.

If refrigerant gas has leaked during the installation work, ventilate the room immediately. If the leaked refrigerant gas comes in contact with fire, noxious gas may generate.

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.

Tighten the flare nut with a torque wrench in the specified manner. Excessive tighten of the flare nut may cause a crack in the flare nut after a long period, which may result in

refrigerant leakage. Nitrogen gas must be used for the airtight test. The charge hose must be connected in such a way that it is not slack. 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. Before operating the air conditioner after having completed the work, check that the electrical control box cover

of the indoor unit and service panel of the outdoor unit are closed, and set the circuit breaker to the ON position. You may receive an electric shock if the power is turned on without first conducting these checks.

Once the repair work has been completed, check for refrigerant leaks, and check the insulation resistance and water drainage.

Then perform a trial run to check that the air conditioner is running properly. After repair work has finished, check t here i s no trou ble. 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.

Be sure to fix the screws back which have been removed for installation or other purposes.

Do not

operate the

unit with the

valve closed.

Check after

reinstallation

Check the following matters before a test run after repairing piping.

• Connect the pipes surely and there is no leak of refrigerant.

• The valve is opened.

Running the compressor under condition that the valve closes causes an abnormal high pressure resulted in damage of the parts of the compressor and etc. and moreover if there is leak of refrigerant at connecting section of pipes, the air is sucked and causes further abnormal high pressure resulted in burst or injury.

Only a qualified installer (*1) or qualified service person (*1) is allowed to relocate the air conditioner. It is dangerous for the air conditioner to be relocated by an unqualified individual since a fire, electric shocks, injury, water leakage, noise and/or vibration may result.

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. When carrying out the pump-down work shut down the compressor before disconnecting the refrigerant pipe.

Disconnecting the refrigerant pipe with the service valve left open and the compressor still operating will cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level, and possibly resulting in reputing, injury, etc.

6. REFRIGERANT R410A

FILE NO. SVM-12004

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.

6-1. 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 fandriven heater, space heater, etc., a poisonous gas may occur.

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 may result in water leakage, electric shock and fire, etc.

6-2. Refrigerant Piping Installation

6-2-1. 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 6-2-1.

Never use copper pipes thinner than 0.8 mm even when it is available on the market.

2. Joints

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 6-2-3 to 6-2-6 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 6-2-2.

6-2-2. 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 than lubricating oils used in the installed air-water heat pump 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.

c) Insertion of Flare Nut

– 19 –

Page 20

d) Flare Processing

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 6-2-7 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.

6-3. Tools

6-3-1. Required Tools

The service port diameter of packed valve of the outdoor unit in the air-water heat pump using R410A is changed to prevent mixing of other refrigerant.

To reinforce the pressure-resisting strength, flare processing dimensions and opposite side dimension of flare nut (For Ø12.7 copper pipe) of the refrigerant piping are lengthened.

The used refrigerating oil is changed, and mixing 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.

6-4. 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.

fully closed position, and turn off the vacuum pump’s power switch.

Connect the charge hose to the vacuum pump adapter.

Open fully both packed valves at liquid and gas sides.

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.

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

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.)

CAUTION

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.

6-5. Brazing of Pipes

6-5-1. 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.

Electronic

balance

Siphon

Fig. 6-4-2

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.

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.

6-5-2. 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.

– 24 –

Page 25

FILE NO. SVM-12004

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.

4. Piping materials for brazing and used brazing filler/flux

6-5-3. 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 (N2) 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.

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.

3) Heating operation Every 1 minute (60 sec.), the room temperature difference between temperature

detected by Ta and Ts and the varied room temperature value are calculated to obtain the correction value of the frequency command and then the present frequency command is corrected.

Ts (n) – Ta (n) : Room temp. difference n : Counts of detection Ta (n) – Ta (n – 1) : Varied room temp. value n – 1 : Counts of detection of 1 minute before

4) Dry operation The frequency correction control is same as those of the cooling operation. However the maximum frequency is limited to approximately “S6”.

Note) When LOW is set up, the maximum frequency is limited to approximately “SB”.

WARNING

• Since high voltages pass through the electrical parts, turn off the power without fail before proceeding with

the repairs. Electric shocks may occur if the main power supply switch or breakers are not turned off.

• After the repairs have been completed (after the front panel and cabinet have been installed), perform a test

run, and check for smoking, unusual sounds and other abnormalities. If this check is omitted, a fire and/or electric shocks may occur. Before proceeding with the test run, install the front panel and cabinet.

• Ensure that the following steps are taken when doing repairs on the refrigerating cycle.

1. Do not allow any naked flames in the surrounding area. If a gas stove or other appliance is being used, extinguish the flames before proceeding. If the flames are not extinguished, they may ignite any oil mixed with the refrigerant gas.

2. Do not use welding equipment in an airtight room. Carbon monoxide poisoning may result if the room is not properly ventilated.

3. Do not bring welding equipment near flammable objects. Flames from the equipment may cause the flammable objects to catch fire.

• If keeping the power on is absolutely unavoidable while doing a job such as inspecting the circuitry, wear rubber gloves to avoid contact with the live parts.

Electric shocks may be received if the live parts are touched. High-voltage circuits are contained inside this unit. Proceed very carefully when conducting checks since directly touching the parts on the control circuit board

may result in electric shocks.
