DRAIN WORK
1) Use drain socket for drainage and attach drain cap.
2) If the drain port is covered by a mounting base or floor surface,
place additional foot bases of at least 30mm (1-3/16") in height
under the outdoor unit’s feet.
3) In cold areas, do not use a drain socket, hose and caps with the
outdoor unit.
(Otherwise, drain water may freeze, impairing heating performance.)

CAUTION
If the unit is installed in a cold climate, take adequate
measures so that the evacuated condensate CANNOT freeze.
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)
Put the flare nut on the pipe.
4)
Flare the pipe.
5)
Check that the flaring is properly made.
WARNING
•
Do not use mineral oil on flared part.
•
Prevent mineral oil from getting into the system as this would
reduce the lifetime of the units.
•
Never use piping which has been used for previous installations.
•
Only use parts which are delivered with the unit.
•
Do never install a drier to this unit in order to guarantee its lifetime.
•
The drying material may dissolve and damage the system.
•
Incomplete flaring may cause refrigerant gas leakage.
(Cut exactly at
right
angles.)
Remove
burrs.
