SAFETY PRECAUTION
CAUTIONS RELATED TO NEW REFRIGERANT
<Cautions for units utilizing refrigerant R410A>
Use new refrigerant pipes.
Do not use refrigerant other than R410A.
In case of using the existing pipes for R22, be careful with
the followings.
· For RP4, 5 and 6, be sure to perform replacement operation before test run.
· Change flare nut to the one provided with this product.
Use a newly flared pipe.
· Avoid using thin pipes.
If other refrigerant (R22 etc.) is used, chlorine in refrigerant can cause deterioration of refrigerant oil etc.
Make sure that the inside and outside of refrigerant 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.
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.
Tools (for R410A)
Gauge manifold
Flare tool
Charge hose
Size adjustment gauge
Vacuum pump adaptor
Gas leak detector
Torque wrench
Electronic refrigerant
charging scale
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
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.)
Keep the tools with care.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
If dirt, dust or moisture enter into refrigerant cycle, that can
cause deterioration of refrigerant oil or malfunction of compressor.
Use ester oil, ether oil or alkylbenzene oil (small
amount) as the refrigerant oil applied to flares
and flange connections.
If large amount of mineral oil enter, that can cause deterioration of refrigerant oil etc.
Charge refrigerant from liquid phase of gas
cylinder.
Do not use a charging cylinder.
If a charging cylinder is used, the composition of refrigerant will change and the efficiency will be lowered.
Ventilate the room if refrigerant leaks during
operation. If refrigerant comes into contact with
a flame, poisonous gases will be released.
If the refrigerant is charged from gas phase, composition
change may occur in refrigerant and the efficiency will be
lowered.
[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) 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.)
