Drain work
CAUTION
In cold areas, do not use a drain socket, drain caps (1,2)
and a drain hose with the outdoor unit. (Drain water may
freeze, impairing heating performance.)
• If the drain port is covered by a mounting base or floor
surface, place additional foot bases of at least 1-1/4
inch (30mm) in height under the outdoor unit's feet.
1) Attach

2) Attach

drain socket.
• When attaching
frame, make sure to connect the drain hose to the
drain socket first.

Flaring the pipe end
WARNING
• Do not apply mineral oil to the flare.
• Prevent mineral oil from getting into the system as this would reduce the service life of the units.
• Never use piping which has been used for previous installations. Only use parts which are delivered with this unit.
• Never install a dryer to this R410A unit in order to guarantee its service life.
• The drying material may dissolve and damage the system.
• Improper flaring may result in refrigerant gas leakage.
CAUTION
Do not reuse joints which have been used once already.
1) Cut the pipe end with a pipe cutter.
2) Remove burrs with the cut surface facing
downward, so that the filings do not enter the
pipe.
3) Put the flare nut on the pipe.
4) Flare the pipe.
5) Check that the flaring has been done correctly.
