CAUTION
• To avoid the attached drain hose (2) getting excessive
force, do not bend nor twist it.
It may cause water leakage.
• As for drain piping connection, do not connect the drain
hose directly to a 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.)
• In case of centralized drain piping, carry out piping work
according to the procedure shown in the fol lowing Fig. 17.
Centralized drain piping
Make a downward inclination of 1/100
or more to avoid stagnation of air.
• As for the size of centralized drain piping, select the size
that meets the capacity of indoor units to be con nected.
(Refer to the technical document.)
• Positioning the upward drain piping at an angle may cause
switch malfunction and lead to water leakage.
• While replacing with new indoor unit, use the attached
new drain hose (2) and the metal clamp (1).
If an old drain hose or a metal clamp is used, it may
cause water leakage.

at the bottom of the drain socket on the left side of the
drain socket into the drain pan giving caution to avoid

1. Open the control box lid and connect the single phase
220 - 240 V power supply to the terminal (L, N) on the
terminal block (X1M).
Connect the earth wiring to the earth terminal.
2. Make sure the control box lid is closed before turning
on the power supply.
• Throughout the whole process, carry out the work
giving caution to the wiring around the control box
so that the connectors may not come off.
3. Gradually pour 1 liter of water from the air outlet on
the left side of the drain socket into the drain pan
giving caution to avoid splashing water on the electric
components such as drain pump. (Refer to Fig. 18)
4. When the power supply is turned on, the drain pump
will operate. Drainage can be checked at the trans-
parent part of the drain socket.
(The drain pump will automatically stop after 10
minutes.)
The drainage of water can be

• Do not connect the drain piping directly to the sew-
age 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.

• Do not touch the drain pump.
Touching the drain pump may cause electric shocks.
5. Turn off the power supply after checking drainage,
and remove the power supply wiring.
6. Attach the control box lid as before.
(3) Sweating may occur and result in water leakage.
Therefore, make sure to insulate the following 2 loca-
tions (drain piping that laid indoors and drain sockets).
• Use the provided sealing material (large) (6), and per-
form the thermal insulation of the metal clamp (1) and
drain hose (2) after checking the drainage of water.
