NOTE:
On the U101 Innova freezer, the temperature sensor port is located on the
left-hand side wall.
For Upright Freezers:
1.
The temperature sensor is fitted through one of the two plugged holes.
2.
Remove the plug that is not surrounded by four screws and set it aside.
3.
Using the replacement plug provided (black for Innova models and clear for
Premium models), insert the sensor through the hole in the plug and seal it by
pressing the rubber grommet located on the sensor cable into the hole.
4.
Insert the temperature sensor through one of the insulation tubes provided and
push the sensor and insulation tube into the cabinet port. Install the nylon
plug by pressing it into the hole.
5.
Inside the freezer cabinet, position the sensor next to the existing freezer
temperature sensor, located halfway down the rear right-hand corner of the
cabinet. (
For the Model U101, skip now to step 9. For all other models,
complete steps 6 through 8 only.
)
6.
Remove the freezer probe cover inside the freezer cabinet and position the
two sensors side by side. Fasten with the cable ties provided.
7.
Replace the probe cover.
8.
Using two more cable ties, secure the probe cable to the two fixing points
(plastic clips) attached to the cabinet of the freezer.
9.
For the Model U101 freezer, complete Steps 9-12:
the temperature sensor cable
should pass under the fixed shelf and be located on the right side of the internal
cabinet. The probe should be attached directly next to the existing freezer
temperature probe.
10.
Remove the freezer probe cover inside the freezer cabinet and position the two
sensors side by side. Fasten with the cable ties provided.
11.
Replace the probe cover.
12.
Using two more cable ties, secure the probe cable to the two fixing points
(plastic clips) attached to the cabinet of the freezer.
For Chest Freezers:
1.
Remove the right side cover of the freezer exposing the compressor
compartment.
2.
Looking into the compressor compartment, at the top left-hand corner, the
freezer temperature sensor can be seen passing into the freezer cabinet. The
LN
2
backup temperature sensor should be fitted through the same port. This
can be accomplished by creating a hole through the insulation next to the
freezer cabinet probe by inserting a length of ¼-inch or ~6mm metal rod or
tube through the insulation to create a passage for the probe (be sure to keep
the rod or tube perpendicular to the cabinet wall when you insert it through the
insulation).
