water-cut method, otherwise a leak or production of fire is caused at the users’ side.
No fire
When performing repairs using a gas burner, replace the refrigerant with nitrogen gas because the oil that
coats the pipes may otherwise burn.

otherwise the oil mixed with refrigerant gas may catch fire.
2) Do not use a welder in the closed room. When using it without ventilation, carbon monoxide poisoning
may be caused.
