2. Drain work
• Ifthedrainportiscoveredbyamountingbaseoroor
surface, place additional foot bases of at least 1-1/4
inch (30mm) in height under the outdoor unit’s feet.
• 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.)
1) Attach
C
drain cap (1) and
D
drain cap (2).
2) Attach
B
drain socket.
• When attaching
B
drain socket to the bottom
frame, make sure to connect the drain hose to the
drainsocketrst.
3. 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lingsdonotenterthe
pipe.
3) Putthearenutonthepipe.
4) Flare the pipe.
5) Checkthatthearinghasbeendonecorrectly.
Check
The 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.
Set exactly at the position shown below.

WARNING
• Donotapplymineraloiltotheare.
• 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.
• Incompletearingmayresultinrefrigerantgasleakage.
4. Refrigerant piping
CAUTION
• Usethearenutxedtothemainunit.(Thisistopreventthearenutfromcrackingasaresultofdeteriorationovertime.)
• Topreventgasleakage,applyrefrigerationoilonlytotheinnersurfaceoftheare.(UserefrigerationoilforR410A.)
• Useatorquewrenchwhentighteningthearenutstopreventdamagetothearenutsandgasleakage.
• Alignthecentersofbotharesandtightenthearenuts3or4turnsbyhand,thentightenthemfullywithaspanneranda
torque wrench.
Do not apply refrigeration
oil to the outer surface.
Flare nut
Apply refrigeration
oil only to the inner
surface of the flare.
Do not apply refrigeration oil to
the flare nut to avoid tightening
with excessive torque.
