SAFETY PRECAUTION

Cautions for units utilising refrigerant R410A

3-2. CAUTIONS RELATED TO NEW REFRIGERANT

Use new refrigerant pipes.

Make sure that the inside and outside of refrige-

rant piping is clean and it has no contamination

such as sulfur hazardous for use, oxides, dirt,

shaving particles, etc.

In addition, use pipes with speciﬁed thickness.

Store the piping to be used indoors during

installation and both ends of the piping sealed

until just before brazing. (Leave elbow joints, etc.

in their packaging.)

Use ester oil, ether oil or alkylbenzene oil (small

amount) as the refrigerant oil applied to ﬂares

and flange connections.

In case of using the existing pipes for R22, be careful with

the followings.

· For RP100, 125 and 140, be sure to perform replace-

ment operation before test run.

· Change flare nut to the one provided with this product.

Use a newly flared pipe.

· Avoid using thin pipes.

Charge refrigerant from liquid phase of gas

cylinder.

If the refrigerant is charged from gas phase, composition

change may occur in refrigerant and the efficiency will be

lowered.

Do not use refrigerant other than R410A.

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

rant can cause deterioration of refrigerant oil etc.

Use a vacuum pump with a reverse ﬂow check

valve.

Vacuum pump oil may flow back into refrigerant cycle and

that can cause deterioration of refrigerant oil etc.

Use the following tools speciﬁcally designed for

use with R410A refrigerant.

The following tools are necessary to use R410A refrigerant.

Handle tools with care.

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

cause deterioration of refrigerant oil or malfunction of com-

pressor.

Do not use a charging cylinder.

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

nt will change and the efficiency will be lowered.

Tools for R410A

Contamination inside refrigerant piping can cause deterio-

ration of refrigerant oil etc.

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

cause deterioration of refrigerant oil or malfunction of com-

pressor.

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

ration of refrigerant oil etc.

Ventilate the room if refrigerant leaks during

operation. If refrigerant comes into contact with

a ﬂame, poisonous gases will be released.

[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 speciﬁed amount of refrigerant.

(4) When performing service, install a ﬁlter drier simultaneously.

Be sure to use a ﬁlter drier for new refrigerant.

[2] Additional refrigerant charge

When charging directly from cylinder

· Check that cylinder for R410A on the market is syphon type.

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

3-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply

circuits must be disconnected.
