CAUTION
• Do not apply excessive force to the attached drain
hose (1) by bending or twisting it.
This could cause water leakage.
• In case of centralized drain piping, carry out piping work
according to the procedure shown in the fol lowing Fig. 18.
Centralized drain piping
Make a downward inclination of 1/100
or more to avoid stagnancy of air.
If water stagnates in the drain
piping, it may cause clogging of
drain piping.
Fig. 18
• Select a size for the centralized drain piping that meets
the capacity of indoor units to be con nected. Refer to
the technical document.
• When installing the new indoor unit, use the attached
new drain hose (1) and the metal clamp (2).
If an old drain hose or a metal clamp is used, it may
cause water leakage.
(2) After piping is finished, check if the drain flows
smoothly.
[When the electric wiring work is finished]
• Gradually pour 1/4 gal. (1 L) of water from the air outlet
on the left side of the drain socket into the drain pan
using caution to avoid splashing water on the electric
components such as the drain pump. Confirm drain-
age by operating the indoor unit under cooling mode
according to 9. FIELD SETTING AND TEST OPERA-
TION. (Refer to Fig. 19)

• If a qualified person is not present, after the electric
wiring work is finished, check the drainage accord ing
to the method specified in [When the electric wiring
work is finished].
