MAINTENANCE
Model: 7~12HP
Notes:
●
The compressor and piping are connected by brazing. Before brazing work, ensure that there is no ammable material nearby, as
remaining oil inside the piping may ignite.
●
To prevent contamination of the refrigerant by water or foreign materials, do not expose the refrigerant parts to atmosphere for long
periods. If necessary, seal the pipe ends using caps or tape.
●
Remove the caps for piping of the new compressor right before replacement. When replacing the compressor, seal the suction and
discharge pipes with tape to prevent water and foreign particles entering the compressor, and remove it right before brazing work.
(6) Disconnect the suction pipe and discharge pipe from the compressor with a torch.
Ensure that wiring and electrical parts are kept away from the brazing area. If not, they may catch re at brazing work.
(7) Remove all securing to the compressor. Tilt the compressor forward, lift it up and remove it.
(8) When performing the brazing work for the replaced compressor, work quickly and do not overheat piping and ttings. Cool area with
a wet cloth to prevent oxidation. Be careful not let the solder or dust ows into the compressor.
