-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)
NOTE)
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

As shown in the figure, store PMV lead wire
connected with connector assembly so that the
connector positions under wire of the terminal.
Details of PMV lead wire drawing
Details of sensor lead wire drawing
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.
Arrow view
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.
2. Attachment
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.
NOTE)
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.
