(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.
! WARNING
(1.) DO NOT use mineral oil on the 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 to
guarantee its lifetime.
(5.) The drying material may dissolve and damage the
system.
(6.) Incomplete flaring may cause refrigerant gas
leakage.
