Use the specied refrigerant only

Never use any refrigerant other than that specified.

Doing so may cause a burst, an explosion, or fire when the unit is being used, serviced, or disposed of.

Correct refrigerant is specified in the manuals and on the spec labels provided with our products.

We will not be held responsible for mechanical failure, system malfunction, unit breakdown or accidents caused by failure to

follow the instructions.

Prepare the proper tools.

Prepare the proper protectors.

Provide adequate ventilation.

After stopping the operation of the air conditioner, turn off the power-supply breaker and pull the power plug.

Discharge the capacitor before the work involving the electric parts.

Do not perform the work involving the electric parts with wet hands.

Do not pour water into the electric parts.

Do not touch the refrigerant.

Do not touch the hot or cold areas in the refrigeration cycle.

When the repair or the inspection of the circuit needs to be done without turning off the power, exercise great caution not to

touch the live parts.

WARNING

• When the refrigeration circuit has a leak, do not execute pump down with the compressor.

• When pumping down the refrigerant, stop the compressor before disconnecting the refrigerant pipes.

The compressor may burst if air etc. get into it.

• When opening or closing the valve below freezing temperatures, refrigerant may spurt out from the gap

between the valve stem and the valve body, resulting in injuries.

SAFETY PRECAUTION2

Use the following tools specically designed for

use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

Tools for R410A

Gauge manifold Flare tool

Charge hose Size adjustment gauge

Gas leak detector Vacuum pump adaptor

Torque wrench Electronic refrigerant

charging scale

Handle tools with care.

If dirt, dust or moisture enters into refrigerant cycle, that can

cause deterioration of refrigerant oil or malfunction of

compressor.

Use the specied refrigerant only.

Never use any refrigerant other than that specied.

Doing so may cause a burst, an explosion, or re when

the unit is being used, serviced, or disposed of.

Correct refrigerant is specied in the manuals and on the

spec labels provided with our products.

We will not be held responsible for mechanical failure,

system malfunction, unit breakdown or accidents caused

by failure to follow the instructions.

Do not use a charging cylinder.

If a charging cylinder is used, the composition of refriger-

ant will change and the e󰀩ciency will be lowered.

Ventilate the room if refrigerant leaks during

operation. If refrigerant comes into contact with

a ame, poisonous gases will be released.

Cautions for units utilizing refrigerant R410A

2-2. CAUTIONS RELATED TO R410A REFRIGERANT

Make sure that the inside and outside of refriger-

ant piping is clean and it has no contaminants

such as sulfur, oxides, dirt, shaving particles, etc.,

which are hazard to refrigerant cycle.

In addition, use pipes with specied thickness.

Contamination inside refrigerant piping can cause deterio-

ration of refrigerant oil, etc.

Store the piping indoors, and keep both ends of

the piping sealed until just before brazing.

(Leave elbow joints, etc. in their packaging.)

If dirt, dust or moisture enters into refrigerant cycle, that can cause

deterioration of refrigerant oil or malfunction of compressor.

The refrigerant oil applied to are and ange

connections must be ester oil, ether oil or

alkylbenzene oil in a small amount.

If large amount of mineral oil enters, that can cause deteri-

oration of refrigerant oil, etc.

Charge refrigerant from liquid phase of gas

cylinder.

If the refrigerant is charged from gas phase, composition

change may occur in refrigerant and the e󰀩ciency will be

lowered.

Do not use refrigerant other than R410A.

If other refrigerant (R22, etc.) is used, chlorine in refrigerant

can cause deterioration of refrigerant oil, etc.

Use a vacuum pump with a reverse ow check

valve.

Vacuum pump oil may ow back into refrigerant cycle and

that can cause deterioration of refrigerant oil, etc.

2-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply circuit must be disconnected.

Preparation before the repair service

• Prepare the proper tools.

• Prepare the proper protectors.

• Provide adequate ventilation.

• After stopping the operation of the air conditioner, turn o󰀨

the power-supply breaker.

• Discharge the condenser before the work involving the

electric parts.

Precautions during the repair service

• Do not perform the work involving the electric parts with

wet hands.

• Do not pour water into electric parts.

• Do not touch the refrigerant.

• Do not touch the hot or cold areas in the refrigerating

cycle.

• When the repair or the inspection of the circuit needs

to be done without turning o󰀨 the power, exercise great

caution not to touch the live parts.

• When opening or closing the valve below freezing

temperatures, refrigerant may spurt out from the gap

between the valve stem and the valve body, resulting in

injuries.

[3] Service tools

(1) Use the below service tools as exclusive tools for R410A refrigerant.

[2] Additional refrigerant charge

When charging directly from cylinder

(1) Check that cylinder for R410A on the market is a siphon type.

(2) Charging should be performed with the cylinder of siphon stood vertically. (Refrigerant is charged from liquid phase.)

[1] Cautions for service

(1) Perform service after recovering the refrigerant left in unit completely.

(2) Do not release refrigerant in the air.

(3) After completing service, charge the cycle with specied amount of refrigerant.

(4) If moisture or foreign matter might have entered the refrigerant piping during service, ensure to remove them.

2-3. Cautions for refrigerant piping work

Refrigerant R410Ais adopted for replacement inverter series. Although the refrigerant piping work for R410Ais the same as for

R22, exclusive tools are necessary so as not to mix with different kind of refrigerant. Furthermore as the working pressure of

R410A is 1.6 times higher than that of R22, their sizes of flared sections and flare nuts are different.

Thickness of pipes

Since the working pressure of R410Ais higher compared to R22, be sure to use refrigerant piping with thickness shown below.

(Never use pipes of 7/256 in [0.7 mm] or below.)

3/4 19.05 — 5/128 [1.0]

Dimensions of flare cutting and flare nut

The component molecules in HFC refrigerant are smaller compared to conventional refrigerants. In addition to that, R410A is

a refrigerant, which has higher risk of leakage because its working pressure is higher than that of other refrigerants. Therefore,

to enhance airtightness and strength, flare cutting dimension of copper pipe for R410A has been specified separately from the

dimensions for other refrigerants as shown below. The dimension B of flare nut for R410A also has partly been changed to

increase strength as shown below. Set copper pipe correctly referring to copper pipe flaring dimensions for R410A below. For

1/2 and 5/8 inch pipes, the dimension B changes.

Use torque wrench corresponding to each dimension.
