Minimal temperature adjustment (2 degrees F min/max adjustment) is possible
by turning the thermostat control knob clock-wise for colder temperature and
counter-clockwise for warmer temperatures since the electronic control is pre-
set at the factory.
DO NOT
adjust the thermostat without consulting Polar Temp.
The electronic control is factory set with a computer therefore there is no need
to make field adjustments. The digital display on your new Polar Temp Ice
Merchandiser will show fault codes and other information as described below:
merchandiser reaches 10º F and then cycle on and off between 10º F and 20º F.
If the merchandiser has a condensate evaporator, plug the power cord from it
into the upper receptacle of electrical outlet.
“E1” on the digital display means “faulty air sensor”
“E2” on the digital display means “faulty defrost sensor”
“---“on the digital display means the refrigeration system has been
“turned off”
Mechanical Temperature Control
Automatic Defrost Models • Previous to November 2010
Merchandiser temperature is maintained by a mechanical thermostat that
cycles the condensing unit on and off automatically. On auto-defrost (AD)
models, the temperature control is located on the left end of the evaporator
blower coil assembly. On cold wall models, the control is located on a bracket
under the condensing unit cover. Most mechanical control models will have the
standard mechanical defrost timer. An electronic defrost timer (AT1032-1 is/was
an option) If AT1032-1 is used, the compressor will start momentarily, turn off and
then go into defrost immediately for 15 minutes to be sure the coil is free of frost
and ice. Every time the unit is switched off then will start a new defrost cycle with
the AT1032-1.
The temperature is adjusted by turning the thermostat control knob clock-wise
for colder temperature and counter-clockwise for warmer temperatures. Turning
the control knob fully counter-clockwise will shut power off to the compressor.
DO NOT re-adjust the internal adjustments of the thermostat without consulting
Polar Temp.
Electronic Temperature Control
Automatic Defrost Models – ETC-1H • November 2010 to March 2012
Merchandiser temperature is maintained by an electronic thermostat that
cycles the condensing unit on and off automatically. On auto-defrost (AD)
models, the temperature control is located on the left end under the hood on
outdoor units and to the left of the condensing unit on indoor skirt hood models.
