OPERATING PROCEDURE
4. Removing the thermistor <Plate HEX liquid> (TH6) and
thermistor <Ambient> (TH7)
(1) Remove the service panel. (See Photo 1)
(2) Remove the top panel. (See Photo 1)
(3) Disconnect the connectors, TH7/6 (red) on the controller
circuit board in the electrical parts box.
(4) Loosen the 2 wire clamps on top of the electrical parts
box. (TH7 only)
(5) Loosen the fastener for the lead wire on the controller
circuit board in the electrical parts box.
(6) Loosen the cable strap and wire clamp for the lead wire
on the bottom of electrical parts box. (TH6 only)
(7) Pull out the thermistor <Plate HEX liquid> (TH6) and
thermistor <Ambient> (TH7) from the sensor holder.
Note: In case of replacing thermistor <Plate HEX liquid>
(TH6) or thermistor <Ambient> (TH7), replace it
together.

TH3, TH4 and TH34 are fixed together with a cable tie.
When exchanging TH4 and TH34, cut the cable tie bundling
TH3, TH4 and TH34 to release the lead wires.
6. Removing the thermistor <Liquid> (TH3) and thermistor
<Suction> (TH33)
(1) Remove the service panel. (See Photo 1)
(2) Disconnect the connectors TH3 (white) and TH33 (yellow)
on the controller circuit board in the electrical parts box.
(3) Loosen the fastener for the lead wire on the controller
circuit board in the electrical parts box.
(4) Loosen the cable strap for the lead wire on the bottom of
electrical parts box. *
(5) Loosen the wire clamp and wire clip on separator.
(6) Pull out the thermistor <Liquid> (TH3), <Suction> (TH33)
from the sensor holder.
