3) Once refrigerant piping and drain piping connections are complete, fill in the gap of the through hole with putty. A gap
can lead to condensation on the refrigerant pipe, and drain pipe, and the entry of insects into the pipes.
4) Attach the front panel and front grille in their original positions once all connections are complete.
Flaring the pipe end
1)Cut the pipe end with a pipe cutter.
2)Remove burrs with the cut surface facing downward so that the chips do not enter the pipe.
3)Fit the flare nut on the pipe.
4)Flare the pipe.
5)Check that the flaring is properly made.

DO not use mineral oil on flared part.
2)
Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
3)
Never use piping which had been used for previous installations. Only use parts which are delivered with the unit.
4)
Do never install a drier to this R410A unit in order to guarantee its lifetime.
