Electric
parts box

1) Perform works of procedure 

1

 -1-and 

2

 -1.

2) Remove connectors of the lead wire connected to the following connectors of the control

P.C. board.

CN33 : Flap motor (5P, White)
CN34 : Float switch (3P, Red)
CN68 : Drain pump (3P, Blue)
CN100 : TC1 sensor (3P, Brown)
CN101 : TC2 sensor (2P, Black)
CN102 : TCJ sensor (2P, Red)
CN82 : PMV (6P, Blue)
CN333 : Fan motor power supply (5P, White)
CN334 : Fan motor position detection (5P, White)

Remove the connectors after unlocking the lock of the housing.

3) Remove each lead wire

from cord clamps in the
electric parts box.

4) Remove the power supply

wiring, remote controller
wiring, and crossover wiring.

5) Take off screws

(Ø4 × 10, 2 pcs.)

Fix the lead wires with cord clamp 
so that the lead wires do not slacken 
at P.C board side. (2 positions)

As shown in the figure, store PMV lead wire 
connected with connector assembly so that the 
connector positions under wire of the terminal.

Fix the sensor lead wires firmly with the cord clamp so that 
they do not touch with the caution plate of the terminal block 
and they do not slacken at P.C. board side. (3 positions)
Arrange the clamp at the position as shown in the figure.

Fold back the sensor lead wire and 
fix it surely with the cord clamp.

Adhere on the transformer.

Be sure that the 
float switch lead wire positions 
at inner side of the fan motor lead wire.

Fold back the float switch lead wire 
and fix surely with cord clamp. 
(There is no catching-in of P.C. board 
and lead wire.)

Arrange at position 
as shown in the figure.

1) Tighten screws (Ø4 × 10, 2 pcs.) fixing the electric parts box.

2) Connect the connectors as original before being removed in item 1.

3) Perform power supply wiring, remote controller wiring, and crossover wiring between inside

and outside.

For drawing of each wire and position of ferrite core, perform wiring same as those before remov-
ing. If there is incomplete drawing of wire, short or water leakage of the parts may be caused.
