Drain work
CAUTION
• In cold areas, do not use a drain socket, drain plugs 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 3-15/16 inch (100mm) in height under the outdoor unit's feet.
1) Insert the
D
drain plug into the bottom frame until it is flush with the bottom frame
around the entire circumference, as shown in area A.
Be careful not to push in
the drain plug too far.

inserted and there is no leakage.
3.
Flaring the pipe end
WARNING
• Do not use mineral oil on flared part.
• 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 the 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.
• Incomplete flaring may cause 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 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.
