SAFETY PRECAUTION
2-1. ALWAYS OBSERVE FOR SAFETY
Before obtaining access to terminal, all supply circuits must be disconnected.
2-2. CAUTIONS RELATED TO NEW REFRIGERANT
Cautions for units utilising refrigerant R410A
Use new refrigerant pipes.
In case of using the existing pipes for R22, be careful with the followings.
·For RP100, 125 and 140, 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.
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.
Contamination inside refrigerant piping can cause deterioration of refrigerant oil etc.
Store the piping to be used indoors during installation, and keep 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.
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 enters, that can cause deterioration of refrigerant oil etc.
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 refrigerant 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.
|
Tools for R410A |
|
Gauge manifold |
|
Flare tool |
Charge hose |
|
Size adjustment gauge |
Gas leak detector |
|
Vacuum pump adaptor |
Torque wrench |
|
Electronic refrigerant |
|
|
charging scale |
Handle tools with care.
If dirt, dust or moisture enters into refrigerant cycle, that can cause deterioration of refrigerant oil or malfunction of compressor.
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.
[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 on the market is syphon type.
·Charging should be performed with the cylinder of syphon stood vertically. (Refrigerant is charged from liquid phase.)
