Purging the Unit
On delivery, the indoor unit is loaded with an inert Nitrogen gas.
All this gas must therefore be purged before connecting the assembly piping.
To purge the inert gas, proceed as follows.
1Unscrew the caps at the end of each pipe.
Result: All inert gas escapes from the indoor unit.
Note To prevent dirt or foreign objects from getting into the pipes
during installation, do NOT remove the caps completely until you are
ready to connect the piping.
Connecting the Refrigerant Pipe
There are two refrigerant pipes of differing diameters:
 A smaller one for the liquid refrigerant
 A larger one for the gas refrigerant
 The inside of copper pipe must be clean & has no dust
1
Before connecting the refrigerant pipe, open the cover side.
2
Remove the pinch pipe on the pipes and connect the assembly pipes
to each pipe, tightening the nuts, first manually and then with a torque
wrench, a spanner applying the following torque.
