(a) Install the No. 1 cooler thermistor as shown in the illustration.

Installation Position:

Part

Length

A

45 to 55 mm (1.77 to 2.17 in.)

B

23 to 27 mm (0.906 to 1.06 in.)

C

54.4 mm (2.14 in.)

D

61.1 mm (2.41 in.)

NOTICE:

  • Be sure to insert the No. 1 cooler thermistor only once because reinserting it into the same position will not allow it to be firmly secured.
  • When reusing the No. 1 cooler evaporator sub-assembly, insert the No. 1 cooler thermistor one row next to the one that has been used previously (X in the illustration).
  • After inserting the No. 1 cooler thermistor, do not apply excessive force to the wire.
  • Directly insert the No. 1 cooler thermistor until the edge of the plastic case "a" comes into contact with the No. 1 cooler evaporator sub-assembly "b".
