Cautions for units utilizing refrigerant R410A

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 contaminants

such as sulfur hazardous for use, oxides, dirt,

shaving particles, etc.

In addition, use pipes with specified thickness.

Store the piping indoors, and keep 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 following.

· Be sure to clean the pipes and make sure that the insides

of the pipes are clean.

· 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 enter 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 enter into refrigerant cycle, that can

cause deterioration of refrigerant oil or malfunction of com-

pressor.

If large amount of mineral oil enter, 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.

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.

Unit

Electronic weighing scale

[3] Service tools

Use the below service tools as exclusive tools for R410A refrigerant.

[1] Cautions for service

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

[2] Additional refrigerant charge

When charging directly from cylinder

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

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

No. Tool name Specifications

1Gauge manifold · Only for R410A

· Use the existing fitting specifications. (UNF1/2)

· Use high-tension side pressure of 5.3 MPa·G or over.

2Charge hose · Only for R410A

· Use pressure performance of 5.09 MPa·G or over.

3Electronic weighing scale —

4Gas leak detector · Use the detector for R134a, R407C or R410A.

5Adaptor for reverse flow check · Attach on vacuum pump.
