• If drain work is necessary, follow the procedures below.
2. 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oorsurface,placeadditionalfoot
bases of at least 3-15/16 inch (100mm) in height under the outdoor unit’s feet.

3. Flaring the pipe end
WARNING
• Donotusemineraloilonared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aring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arenutonthepipe.
4) Flare the pipe.
5) Checkthatthearingisproperlymade.
Check
Flare’s inner
surface must be
flaw-free.
The pipe end must
be evenly flared in
a perfect circle.
Make sure that the
flare nut is fitted.
