OPERATING PROCEDURE
4. Removing the thermistor <2-phase pipe> (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 clamp for the lead wire in the rear of the electri-
cal parts box.
(5) Pull out the thermistor <2-phase pipe> (TH6) and thermis-
tor <Ambient> (TH7) from the sensor holder.
Note: In case of replacing thermistor <2-phase pipe> (TH6)
or thermistor <Ambient> (TH7), replace it together.
5. Removing the thermistor <Discharge> (TH4) and thermis-
tor <Comp. surface> (TH34)
(1) Remove the service panel. (See Photo 1)
(2) Disconnect the connector TH4 (white) and TH34 (red) on
the controller circuit board in the electrical parts box.
(3) Loosen clamps for the lead wire in the rear of the electri-
cal parts box and the separator. (See Photo 4-1)
(4) Pull out the thermistor <Discharge> (TH4) from the sensor
holder.
[Removing the thermistor<Comp. surface> (TH34)]
(5) Remove the sound proof cover (upper) for compressor.
(6) Pull out the thermistor <Comp. surface> (TH34) from the
holder of the compressor shell.
6. Removing the thermistor <Liquid> (TH3), thermistor
<Suction> (TH32) and thermistor <Ref. check> (TH33)
(1) Remove the service panel. (See Photo 1)
(2) Disconnect the connectors, TH3 (white) and TH32 (black),
TH33 (yellow) on the controller circuit board in the electri-
cal parts box.
(3) Loosen clamps for the lead wire in the rear of the electrical
parts box (See Photo 4-1) and separator (See Photo 5).
