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 fol lowing Fig. 18.
Centralized drain piping
Make a downward inclination of 1/100
or more to avoid stagnancy of air.
• 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)
• 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 on the
left side of the drain socket into the drain pan giving cau-
tion 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. 19)

(Tube length of 100 mm or more
is necessary.)
[Method of adding water]
• After checking the drainage of water, refer to Fig. 20 and
attach the sealing material (14) to perform the thermal
insulation of the drain socket.

If water stagnates in the drain
piping, it may cause clogging of
drain piping.

[When the electric wiring work is not finished]
• The electric wiring works (including earthing) must be
carried out by a qualified electrician.
• If a qualified person is not present, after the electric wir-
ing work is finished, check the drainage accord i ng to the
method specified in [When the electric wiring work is
finished].
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 (X2M).
Connect the earth wiring to the earth terminal. (Refer
to Fig. 21)

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. 19)
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.)
After checking the drainage of water, refer to Fig. 20
and attach the sealing material (14) to perform the
thermal insulation of the drain socket.
