Evaporator Temperature Sensor Assembly Note

1. Assemble the evaporator temperature sensor as shown in the figure.

CAUTION:

When installing the evaporator temperature sensor without replacing the evaporator, assemble the evaporator temperature sensor with the installation position slid to the left of the previous position by 1 line. If the evaporator temperature sensor is assembled to the previously installed position, it may not function due to poor contact of the fin surface with the sensor detection area caused by fin deformation.

NOTE:

Replace the evaporator in which the evaporator temperature sensor cannot be correctly positioned.

Adhesive Polyurethane (2) Assembly Note

1. Assemble the adhesive polyurethane as shown in the figure.
