NOTE)

Remove the connectors after
unlocking the lock of the housing.	Ferrite core for sensor lead
3) Unlock the lock of the card
edge spacer (6 positions)
and then remove the
control P.C. board.

Drawing-out port of lead wire Ferrite core for fan motor

2.Attachment

1)Fix the control P.C. board to the card edge spacer. (6 positions)

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

NOTE)

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

Fix the sensor lead wires with cord clamps (2 positions) so that

it does not slacken at P.C. board side and draw wires as shown in the figure.

Please note the

float SW lead wires are set at inner side of the fan motor lead wires.

As shown in the figure, hook the sensor lead wires to claw of the piping cover and then pass them so that they are stored in the groove.

After mounting the piping cover, check each lead wire does not hit the liquid pipe.

Cord clamp

Turn up the fan motor lead wires and fix surely with the cord clamp. (There should be no catching of lead wire by P.C. board.)

Clamp (yellow, gray, black) lead wires of the fan motor and arrange them as shown in the figure.
