2. A “well” is provided at the bottom of each holding plate for the temperature probe. The probe
must be fully inserted into the well and the hole sealed with putty, caulk or foam. If a single box
(ie. “zone”) has multiple holding
plates, the probe should go into
the largest of them. If the holding
plates are all the same size, the
one nearest the wire entry point
can be used.

3. If you purchased the optional
box temperature probes, you
should know that they are
identical to, and interchangeable
with, plate temperature probes.
They will just be wired to different
connectors on the control. You
will want to mount your box
temperature probes as near as
possible to mid-point in the box. Choosing the “best” location to measure box temperature is
always problematic due to a common lack of an out-of-the-way place to secure the probes.
Compromises usually have to be made. Probes mounted at the top of the box generally
measure temperatures above the “average” while probes mounted at the bottom may read lower
than the box average. While you may want to secure the probe wire to the side of the box, make
certain that the actual probe itself rests at least 1/2" (12mm) away from the wall and is exposed
to free air circulation.

4. The standard wire length for all temperature probes is 59" (1500 mm). The wire can be
lengthened to any distance required with regular marine 18 AWG to 22 AWG wire. When
lengthening the wire all connections must be soldered and sealed with glue-lined heat-shrink
tubing. Securely fasten the wire inside the box so that it is out of the way and cannot come loose
to pull the probe from inside the plate. (This is a Prestart Checkout Item)

evaporator plates in a zone is determined by your
box size and quality of insulation. If you have web access you can use the box heat load
calculator on our web site at: http://www.glacierbay.com/Heatload_calculator/heatload.htm
to determine the expected daily heat load on a 90 degree F (32 degree C) average day. Divide
the daily heat load by 24 to get the hourly heat influx in your box in BTUs.
The heat removal capacity of each plate is determined by plate surface area and is the same for
both reefer and freezer plates.
The heat capacities are as follows:
(S.A. is plate surface area in square feet. L” includes 4" for the valve and tubing.)
