2. ABOUT THE UNIT

2.1.

Precautions for using R410A refrigerant

The basic installation work procedures are the same as conventional refrigerant (R22)

models.

However, pay careful attention to the following points:

Since the working pressure is 1.6 times higher than that of conventional refrigerant

(R22) models, some of the piping and installation and service tools are special. (See

the table below.)

Especially, when replacing a conventional refrigerant (R22) model with a new refrigerant

R410A model, always replace the conventional piping and flare nuts with the R410A piping

and À are nuts.

Models that use refrigerant R410A have a different charging port thread diameter to pre-

vent erroneous charging with conventional refrigerant (R22) and for safety. Therefore,

check beforehand. [The charging port thread diameter for R410A is 1/2 inch.]

Be more careful that foreign matter (oil, water, etc.) does not enter the piping than with

refrigerant (R22) models. Also, when storing the piping ,securely seal the opening by

pinching, taping, etc.

When charging the refrigerant, take into account the slight change in the composition of

the gas and liquid phases. And always charge from the liquid phase where refrigerant

composition is stable.

2.2. Special tools for R410A

Tool name Contents of change

Gauge manifold

Pressure is high and cannot be measured with a conven-

tional (R22) gauge. To prevent erroneous mixing of other

refrigerants, the diameter of each port has been changed.

It is recommended the gauge with seals -0.1 to 5.3 MPa

(-1 to 53 bar) for high pressure.

-0.1 to 3.8 MPa (-1 to 38 bar) for low pressure.

Charge hose

To increase pressure resistance, the hose material and base

size were changed.

Vacuum pump

A conventional vacuum pump can be used by installing a

vacuum pump adapter.

Gas leakage detector

Special gas leakage detector for HFC refrigerant R410A.

Copper pipes

It is necessary to use seamless copper pipes 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 value or

capillary tube may become blocked with contaminants.

As an air conditioner using R410A incurs pressure higher than when using R22, it is neces-

sary to choose adequate materials.

WARNING

Do not use the existing (for R22) piping and À are nuts.

If the existing materials are used, the pressure inside the refrigerant cycle will rise and

cause failure, injury, etc. (Use the special R410A materials.)

When installing and relocating the air conditioner, do not mix gases other than

the speci¿ ed refrigerant (R410A) to enter the refrigerant cycle.

If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to

an abnormally high value and cause failure, injury, etc.

6.6.2. Bending pipes

• If pipes are shaped by hand, be careful not to collapse them.

• Do not bend the pipes in an angle more than 90°.

• When pipes are repeatedly bend or stretched, the material will harden, making it dif¿ cult

to bend or stretch them any more.

• Do not bend or stretch the pipes more than 3 times.

CAUTION

• To prevent breaking of the pipe, avoid sharp bends.

• If the pipe is bent repeatedly at the same place, it will break.

6.6.3. Pipe connection

CAUTION

• Be sure to Install the pipe against the port on the indoor unit correctly. If the centering

is improper, the À are nut cannot tighten smoothly. If the À are nut is forced to turn, the

threads will be damaged.

• Do not remove the À are nut from the indoor unit pipe until immediately before con-

necting the connection pipe.

• Hold the torque wrench at its grip, keeping it in the right angle with the pipe, in order

to tighten the À are nut correctly.

• Tighten the À are nuts with a torque wrench using the speci¿ ed tightening method.

Otherwise, the À are nuts could break after a prolonged period, causing refrigerant to

leak and generate hazardous gas if the refrigerant comes into contact with a À ame.

CAUTION

• Connect the piping so that the control box cover can easily be removed for servicing

when necessary.

• In order to prevent water from leaking into the control box, make sure that the piping

is well insulated.
