Purging the Unit
The unit is shipped from the factory with a holding charge of nitrogen. All of this gas must be
purged from the unit.
To purge the unit, unscrew the pinch pipes from the ends of both gas and liquid refrigerant pipes.
Make sure all gas has escaped before connecting the piping.
Note:
To prevent dirt or foreign objects from getting into the pipes during installation, do not
remove the pinch pipes completely until you are ready to connect the piping.
