SAFETY PRECAUTION

Cautions for units utilising refrigerant R410A

CAUTIONS RELATED TO NEW REFRIGERANT

Use new refrigerant pipes.

Store the piping indoors and keep both ends of

the piping sealed until just before brazing.

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

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.

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.

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.

Make sure that the inside and outside of refrige-

rant 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 specified thickness.

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.

Use the specified refrigerant only.

The refrigerant oil applied to flares and flange

connections must be ester oil, ether oil or

alkylbenzene oil in a small amount.

[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 available on the market is syphon type.

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