DRAIN PIPING WORK
Install the drain pipe as shown below and take measures
against condensation. Improperly installed piping could
lead to leaks on furniture and belongings.
(1)
Install drain piping:
• The diameter of the drain pipe should be greater than or
equal to the diameter of the connecting pipe (vinyl tube;
pipe size: 1” (25.4 mm) ; outer dimension: 1 1/4” (31.7
mm). This does not apply to rises.
• Keep the drain pipe short and sloping downwards at a gra-
dient of at least 1/100 to prevent air pockets from forming.
• If the drain hose cannot be sufficiently set on a slope, exe-
cute the drain-raising pipe.
• To keep the drain hose from sagging, space hanging wires
every 3.28 ~ 4.92 ft . (1 ~ 1.5 m)
• Use the attached drain hose 1) and clamp metal 2).
Insert the drain hose into the drain socket, up to the white
tape. Tighten the clamp until the screw head is less than
3/16” from the hose.
• Be sure to insulate the 2 below indicated spots.
If uninsulated, there is always the possibility of con-
densation forming and leaking.
• The drain piping inside the building
• Drain socket
• Wrap the attached sealing pad 10) (Large) over the clamp
and drain hose to insulate, as shown in the drawing below.
NOTE FOR DRAIN RAISING PIPING
• Install the drain raising pipes at a height of less than 21-5/
8” (549.3 mm) .
• Install the drain raising pipes at a right angle to the indoor
unit and no more than 11 13/16” (298.4 mm) from the unit.
NOTE
• The incline of attached drain hose 1) should be 2-15/16”
(71.4 mm) or less so that the drain socket does not have to
withstand additional force.
• If converging multiple drain pipes, install according to the
procedure shown below.
Select converging drain pipes whose gauge is suitable for the
operating capacity of the unit.
NOTE
• Drain piping connections should not be connected directly
to sewage pipes that smell of ammonia. The ammonia in
the sewage might enter the indoor unit through the drain
pipes and corrode the heat exchanger.
• Remember that water collecting on the drain pipe will block
it.
(2) After piping work is finished, check if drainage flows
smoothly.
• Open the water inlet lid, add approximately 37 in
3
of
water slowly and check drainage flow.
WHEN ELECTRIC WIRING WORK IS FINISHED
• Check drainage flow during COOL running, explained
under
