•
Bend the tip of the metal clamp (2) so that the sealing mate-
rial does not bulge.
(Refer to Fig. 26)
•
When performing insulation, wind the sealing material
(Large) (8) attached starting from the base of the metal
clamp (2) and drain hose (1) in the direction of the arrow.
(Refer to Fig. 25 and 26)
•
Be sure to insulate all drain piping running indoors.
•
Do not deflect the drain hose (1) inside of the indoor unit.
(Refer to Fig. 27)
(It may cause abnormal noise such as bubbling noise.)
(If the drain hose (1) is deflected, it may damage the suction
grille.)
•
Install supports at a distance of 1 to 1.5m so that the piping
may not deflect.
(Refer to Fig. 23)
CAUTION
To prevent dust from entering the indoor unit, cover the gap
with the drain piping by putty or insulation (field supply) so
that no clearance is made.
However, when putting piping and remote controller wiring
through the same hole, cover the gap between the through
cover and the piping after
8. ELECTRIC WIRING WORK
is
completed.
< CAUTION >
•
To avoid the attached drain hose (1) getting excessive
force, do not bend nor twist it. (It may cause water leak-
age.)
•
When conducting the centralized drain piping, follow the
instructions in
Fig. 28
. For the diameter of the centralized
drain piping, select the diameter matching the capacity of
the indoor unit to be connected. (Refer to the technical
document)
•
Connecting drain piping.
Do not connect the drain piping directly to the sewage
that gives off ammonia odor. The ammonia in the sewage
may go through the drain piping and corrode the heat
exchanger of the indoor unit.
•
When installing the drain pump kit (optional accessory),
also refer to the installation manual included to the drain
pump kit.
(2) After piping is finished, check if the drain flows
smoothly.
•
Gradually put about 0.6 liter of water for drain confirmation
into the drain pan from the air outlet.

Centralized drain piping
If water stagnates in the drain
piping, the piping may be
clogged.
100mm
or more
Install with downward inclination
of 1/100 or more so that no air
will be stagnated.
