START-UP
1. Plug in the merchandiser.
The OFF Position does not disconnect line
voltage to the case, refrigeration unit, fan,
or heater.
2. Wait for the self check to complete. During
the self check, each LED flashes for one
second, then all LEDs turn on for two
seconds. If the LEDs do not flash, make
sure the adjustment knob is not in the Off
position.
• After the self check, all LEDs turn off
until the compressor starts. There may be a
delay before the compressor starts, if the red
Temperature or Sensor Alarm LED stays
on after the self check.
• The green Compressor Powered On LED
turns on when the compressor starts.

Product will be degraded and may spoil if
allowed to sit in a non-refrigerated area.
NOTE: Do NOT load product until AFTER
merchandiser operates for 24 hours and reaches
desired operating temperature.
1. Apply power to the merchandiser. Wait for
the self check to complete. During the self
check, each LED flashes for one second and
then all LEDs turn on for two seconds. If the
LEDs do not flash, make sure the adjustment
knob is not in the "OFF" position.
1A. The merchandiser temperature displays at
startup. The initial defrost starts two hours
later. The display will show "DF" at the start of
defrost. This reading will remain displayed
during defrost and until it times out, even
though the refrigeration mode has been initi-
ated.
(The green LED will be lit.)
2. The compressor will start after a 30 second
delay once power is applied.
3. The compressor will continue to run until it
reaches its cut-out temperature (Pulldown).
4. The refrigeration cycle will continue for the next
subsequent scheduled defrost.
5. The above process will repeat (steps 3 and 4)
until the power is interrupted.
6. If power stops, the process will start over at step
1, and the time to subsequent defrost will reset.
7. Medium temperature is the same except for a
30-minute time terminated defrost
