MAN # 650702
Using the 3/8” drill bit with the proper rubber
or wood stop installed, drill a hole in the
defrost duct in the location shown.
Insert one of the four supplied grommet type
temperature sensors into the drilled hole with
the wires pointing to the outside of the duct
housing. The sensor should snap into the
hole with the collar of the sensor resting
against the housing.
STEP 2: INSTALLING THE FLOOR SENSORS
Push a clip type temperature sensor onto
the side wall of each opening of the floor
duct so that the sensor sits inside the
duct at about the center of the opening.
It is recommended to label the free end of
the sensor wires to ensure proper
connection to the control box later.
STEP 3: INSTALLING THE CABIN SENSOR
Secure one of the grommet type
temperature sensors to the grate of the
blower fan using the supplied 6” plastic
ties. The sensor should be mounted so
that the silver colored element will be in
the incoming airflow to the fan when the
fan is running.
Be careful that the plastic tie, the sensor,
or its wires will not contact the fan blades
when the fan is running.
Label the wires for the Cabin Sensor for
easier identification later.
