– 4 –

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.

Check earth wires.

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.

 

 

For spare parts, use those specified ( ).

 

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

Use specified parts.

: 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.

Do not bring a child

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.

close to the equipment.

 

 

 

Connect the cut-off lead wires 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

 

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.

No fire

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

Refrigerant

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 wires as before. Perform the work so that the cabinet or panel does not

 

catch the inner wires.

Assembly/Cabling

If incorrect assembly or incorrect wire connection was done, a disaster such as a leak or

fire is caused at user’s side.

 

– 5 –

WARNING

 

After the work has finished, be sure to use an insulation tester set (500V Megger) to

 

check the resistance is 2MΩ or more between the charge section and the non-charge

 

metal section (Earth position).

Insulator check

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

Ventilation

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

 

 

 

 

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.

Compulsion

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.

Check after repair

 

 

 

 

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.

Check 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.

CAUTION

 

Be sure to put on the gloves ( ) and a long sleeved shirt:

 

otherwise an injury may be caused with the parts, etc.

Put on gloves

( ) Heavy gloves such as work gloves

 

 

 

 

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

 

sufficiently cooled.

Cooling check

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 0.0001 lbs / 32’ 10” (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)

6. 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.

6-1. 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.

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 0.0001 lbs / 32’ 10” (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 0.8mm even when it is available on the market.

1.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 6-2-5 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 0.79” (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 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.

– 28 –

c)Insertion of Flare Nut

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 6-2-6 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.
