Reconditioning

(Temperature sensor and setting unit cannot be repaired).

Replacing the Sensor

With engine running, remove screws (6) and take sensor (1) out of pocket (2).

Before fitting a new sensor, check that sensor and setting unit are a match, i.e., their model designations must

have the same figures. (Example: sensor TH 31 will agree with setting unit RH 31.)

Fill pocket 2 with heat compound (5). (Press some 20 mm out of tube.) Secure sensor (1) by screw (6).

Air in the pocket is liable to affect the readings.

Replacing the Setting Unit:

Remove leads and push unit (4) out of terminal bar.

Before fitting a new unit, check for agreement with sensor (see above).

For setting a new unit, see Section 3.3 or rating plate of the old unit.
