After piping is finished, check if the drain flows
smoothly.

Gradually pour 1/4 gal. (1 ) of water from the inspec-

left side of the drain socket into the drain pan giving
caution to avoid splashing water on the electric com-
ponents such as drain pump and confirm drainage by
operating the indoor unit under cooling mode accord-

•
The electric wiring works (including grounding) must
be carried out by a qualified electrician.
•
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]
.
1.
Open the control box lid and connect the single
phase 208/230 V power supply to the terminal (L1,
L2) on the terminal block (X1M).
Connect the ground wiring to the ground terminal.
2.
Make sure the control box lid is closed before turn
-
ing on the power supply.
•
Throughout the whole process, carry out the
work giving caution to the wiring around the con-
trol box so that the connectors may not come off.
3.
Gradually pour 1/4 gal. (1 ) of water from the air out-
let 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 confirmed with water
level change in the drain pan through the access
window.
•
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.
•
Do not apply external force to the float switch. (It
may result in malfunction)
•
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
locations (drain piping that laid indoors and drain
sockets).
•
Use the provided sealing material (Large) (6), and
perform the thermal insulation of the metal clamp (1)
and drain hose (2) after checking the drainage of water.
(Refer to Fig. 19)
Start wrapping from where the
metal clamp (1) is tightened.
Wrap the sealing material (Large) (6)
so that the metal clamp (1) end side
may be doubled.
