11.Removal and Replacement of Thermistor

CAUTION

1.Fragile, handle very carefully.

2.Always use a recommended sealant (high thermal conductive type), Model KE4560RTV manufactured by Shinetsu Silicone, Part Code 60Y000-11, or Part Code 4A0683-01 equivalent.

3.Always use a recommended foam insulation (non-absorbent type) or equivalent.

4.Do not shorten or cut the thermistor leads when installing it.

1) Turn off the power supply.

6)Scrape away the old sealant on the thermistor holder and the suction pipe.

7)Wipe off moisture or condensation on the suction pipe.

8)Smoothly apply recommended sealant (KE4560RTV, Part Code 60Y000-11 or 4A0683-01) to the thermistor holder concave.

9)Attach the new thermistor to the suction pipe very carefully to prevent damage to the leads. And secure it using the thermistor holder and recommended foam insulation.

Note: For models with the liquid bypass, the thermistor should be located upstream from the liquid bypass outlet, and its end should be 4-3/4" or more away from the outlet. See Fig. 3.
