SAFETY PRECAUTION

2

Cautions for units utilising refrigerant R410A

2-2. 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.

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

the following:

· 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.

Flare tool

Electronic refrigerant 

charging scale

Vacuum pump adaptor

Size adjustment gauge

Gauge manifold

Torque wrench

Gas leak detector

Charge hose

Tools for R410A

Contamination inside refrigerant piping 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.

Use the specified 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.

Store the piping indoors, and 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 flare and flange

connections must be ester oil, ether oil or 

alkylbenzene oil in a small amount.

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

ration of refrigerant oil, etc.

2-1. ALWAYS OBSERVE FOR SAFETY

Before obtaining access to terminal, all supply 

circuits must be disconnected.
