Cut the Discharge pipe in this range.
Caution
Keep their shape better.
There is a possibility of catching fire to oil when removing by the welding without cutting it.
Procedure for compressor installation.
Reverse procedure to removing the compressor.
Precautions for installation of Compressor.
(1) When brazing, do not apply the flame to the terminal.
(2) When brazing, be sure to replace the air in the pipe with nitrogen gas to prevent forming oxidization scale.
18. Precautions for when replacing refrigerant-cycle-parts
(1) During replacement of the following parts shall be protected by wet rag and not make the allowable temperature or more.
(2) Remove the heat insulation when there is the heat insulation near the welding place.
Move and cool it when its detaching is difficult.
(3) Cool the parts when there are parts where heat might be transmitted besides the replacement part.
(4) Interrupt the flame with the fire-retardant board when the flame seems to hit the following parts directly.
(5) Do not allow moisture or debris to get inside refrigerant pipes during work.
(6) When brazing, be sure to replace the air in the pipe with nitrogen gas to prevent forming oxidization scale.
