During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing
refrigeration piping and valves at opened condition will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in
explosion, injury etc.
19.
During pump down operation, stop the compressor before removing the refrigeration piping. Removal of refrigeration piping while
compressor is operating and valves are opened will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in
explosion, injury etc.
20.
Tighten the flare nut with torque wrench according to specified method. If the flare nut is over-tightened, after a long period, the flare
may break and cause refrigerant gas leakage.
21.
After completion of installation, confirm there is no leakage of refrigerant gas. It may generate toxic gas when the refrigerant comes into
contact with fire.
22. Ventilate if there is refrigerant gas leakage during operation. It may cause toxic gas when the refrigerant comes into contact with fire.

Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and accumulates at surrounding
of the unit, it may cause fire.
2.
Do not release refrigerant during piping work for installation, re-installation and during repairing a refrigeration parts. Take care
of the liquid refrigerant, it may cause frostbite.
3.
