CAUTION

• To avoid the attached drain hose (1) getting excessive force, do not bend nor twist it.

It may cause water leakage.

• In case of centralized drain piping, carry out piping work according to the procedure shown in the follow-

ing Fig. 14.

• As for the size of centralized drain piping, select the size that meet the capacity of indoor units to be con-

nected. (Refer to the technical document)

• 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.

• At replacement with 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 liter of water from the air outlet into the drain pan giving caution to avoid splashing

water on the electric components such as drain pump and confirm drainage by operating the indoor unit

under cooling mode according to “10. FIELD SETTING AND TEST OPERATION”. (Refer to Fig. 15)

• Do not apply external force to the float switch. (It may result in malfunction)

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.
