SAFETY PRECAUTION

[2] Refrigerant recharging

(1) Refrigerant recharging process

1Direct charging from the cylinder.

· R407C cylinder are available on the market has a syphon pipe.

· Leave the syphon pipe cylinder standing and recharge it.

(By liquid refrigerant)

(2) Recharge in refrigerant leakage case

· After recovering the all refrigerant in the unit, proceed to working.

· Do not release the refrigerant in the air.

· After completing the repair service, recharge the cycle with the specified amount of

liquid refrigerant.

[1] Cautions for service

· After recovering the all refrigerant in the unit, proceed to working.

· Do not release refrigerant in the air.

· After completing the repair service, recharge the cycle with the specified amount of

liquid refrigerant.

Cautions for units utilising refrigerant R407C

CAUTIONS RELATED TO NEW REFRIGERANT

Do not use the existing refrigerant piping.

The old refrigerant and lubricant in the existing piping

contains a large amount of chlorine which may cause the

lubricant deterioration of the new unit.

Use “low residual oil piping”

If there is a large amount of residual oil (hydraulic oil, etc.)

inside the piping and joints, deterioration of the lubricant

will result.

Use ESTER , ETHER or HAB as the lubricant to

coat flares and flange connection parts.

If large amount of mineral oil enter, that can cause

deterioration of refrigerant oil etc.

Use liquid refrigerant to charge the system.

If gas refrigerant is used to seal the system, the composition

of the refrigerant in the cylinder will change and performance

may drop.

Do not use a refrigerant other than R407C.

If another refrigerant (R22, etc.) is used, the chlorine in the

refrigerant may cause the lubricant deterioration.

Use a vacuum pump with a reverse flow check valve.

The vacuum pump oil may flow back into the refrigerant

cycle and cause the lubricant deterioration.

Store the piping to be used during installation

indoors with keep both ends sealed until just

before brazing.

(Store elbows and other joints in a plastic bag.)

If dust, dirt, or water enters the refrigerant cycle,

deterioration of the oil and compressor trouble may result.

Ventilate the room if refrigerant leaks during

operation. If refrigerant comes into contact with

a flame, poisonous gases will be released.

·Use pressure performance of 5.10MPa·G or over.

3Electronic scale

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

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

6Refrigerant charge base.

8Refrigerant recovery equipment.

CAUTIONS RELATED TO NEW REFRIGERANT

Use new refrigerant pipes.

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

the following.

á For RP4 be sure to perform pipe replacement operation

before test run.

á Use flare nut as provided with this product.

Use a newl flared pipe.

áAvoid using thin pipes. For the detail, please refer to the

outdoor unit service manual No. OC294.

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.

If no reverse flow check valve is used, vacuum pump oil

ma flow back into refrigerant c cle and that can cause

deterioration of refrigerant oil etc.

Use the following tools specifically designed for

use with R410A refrigerant.

The following tools are necessar to use R410A refrigerant.

Keep the tools with care.

If dirt, dust or moisture enter into refrigerant c cle, that can

cause deterioration of refrigerant oil or malfunction of com-

pressor.

Do not use a charging cylinder.

If a charging c linder is used, the composition of refrigera-

nt will change and the efficienc will be lowered.

Tools (for R410A)

Make sure that the inside and outside of refrige-

rant piping is clean and it has no contamination

such as sulfur which is hazardous for use,

oxides, dirt, shaving particles, etc.

In addition, use pipes with specified thickness.

Store the piping to be used during installation

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.

Charge refrigerant from liquid phase of gas

cylinder.

If the refrigerant is charged from gas phase, composition

change ma occur in refrigerant and the efficienc will be

lowered.

Contamination inside refrigerant piping can cause deterio-

ration of refrigerant oil etc.

If dirt, dust or moisture enter into refrigerant c cle, 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.

[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 system with the 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

Ensure that the cylinder for R410A is syphon type.

Charging should be performed with the syphon cylinder type stood vertically. (Refrigerant must be charged from liquid phase.)
