Merchandiser temperature is maintained by an electronic thermostat that cycles
the condensing unit on and off automatically. On auto-defrost (AD) models, the
electronic 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.
Minimal temperature adjustment (5 degrees F min/max adjustment) is possible
by pressing the up or down arrow buttons for colder or 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 at the factory 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:
“def” on the digital display means the refrigeration system is in
“defrost cycle”
“E13” on the digital display means “communication error” (cable
between the digital readout and t thecontrol relay is faulty)
“VH” indicates “voltage high”
“VL” indicates “voltage low”
Two buttons on the digital display will do the following:
Pressing both buttons at the same time for 10 seconds will shut the
refrigeration system “OFF” (“---“ shown on the digital display)
Pressing the top button for 10 seconds will give you the option of
temperature display in centigrade (C°) or Fahrenheit (Fº)
Pressing the bottom button for 10 seconds will put the refrigeration
system into a manual defrost (“def” shown on the digital display
The system will automatically return to refrigeration cycle after
temperature 50º F or 15 to 20 minutes is satisfied, whichever comes
first. The system will go into defrost every 60 minutes of “compressor”
run time.
If the electrical power supply is interrupted the electronic control will
always start automatically after a short delay in a new refrigeration
cycle.
“E01” on the digital display means “faulty air sensor”
“E02” on the digital display means “faulty defrost sensor”
“E03” when used is faulty “condenser air sensor”
