OPERATIONS MANUAL
MILK COOLERS FORCED AIR & COLD WALL
NOTE: When in an alarm condition, the display will alter-
nate between the cabinet temperature and alarm code.
“AL” when in a low temperature alarm condition and “AH”
when in a high temperature alarm condition. The control
will also beep and the alarm icon will activate when in an
alarm condition. To silence the alarm beeper for the active
alarm just press and release the “SET/MUTE” button.
ELECTRONIC CONTROL ERROR CODES
When in an alarm condition, the display will alternate between
the alarm code and the current cabinet temperature. The alarm
icon will also illuminate and the beeper will activate. If there is
a regulation probe error, the display will just show alarm code
“E0” and not flash the cabinet temperature. If there is a probe
error, you must contact your service provider immediately.
Alarm Code Alarm Description Notes
E0 Regulation Probe Error Located in return air stream
E1 Evaporator Probe Error Located in evaporator coil
E2 Ambient Probe Error Located on side of electrical box
LO Low Temperature Alarm Reference “AL” parameter
HI High Temperature Alarm Reference “AH” parameter
• Error code “E0”: The control will operate the appliance in
a preprogrammed ON/OFF cycle based on time, not tem-
perature.
• Error code “E1”: The control will still go into a defrost but
will terminate on time, not temperature.
• Error code “E2”: The aux heaters will not operate.
• If the control goes into a high/low temperature alarm, the
beeper will sound and alarm icon will illuminate. When the
temperature goes below the alarm threshold for high tem-
perature alarms or above the alarm threshold for low tem-
perature alarms, the control will go back to normal display.
MAINTENANCE
SAFETY PRECAUTIONS
DISCONNECT POWER BEFORE ATTEMPTING TO WORK

REMOVE ANY COVERS OR PARTS YOURSELF, AS
THIS CAN EXPOSE DANGEROUS, HIGH VOLTAGE
WIRING. SERVICE SHOULD ONLY BE PERFORMED BY
A QUALIFIED TECHNICIAN.
ALWAYS ROUTE POWER CORDS AWAY FROM AREAS
WHERE THEY CAN BE WALKED ON OR DAMAGED BY
OTHER EQUIPMENT. YOUR APPLIANCE IS EQUIPPED
WITH A POLARIZED, GROUNDED POWER PLUG. NEVER
ATTEMPT TO REMOVE THE GROUND POST OR USE
A NON-POLARIZED ADAPTER, WITHOUT PROPERLY
GROUNDING THE EQUIPMENT.
CONDENSER FINS ARE MADE FROM THIN METAL AND

CONDENSING UNIT TO PREVENT CUTS AND AVOID
DAMAGING FINS, TUBING AND OTHER COMPONENTS.
KEEP ELECTRICAL COMPONENTS AND CONTROLS DRY.
DO NOT SPRAY WITH WATER! FAILURE TO FOLLOW
THESE INSTRUCTIONS CAN CAUSE A SAFETY HAZARD
AND VOID FACTORY WARRANTY.
PERIODIC CLEANING PROCEDURE
It is always best to clean your refrigerator or freezer when the
product load in your cabinet is as its lowest level. To clean the
interior or exterior cabinet surfaces, follow these procedures:
1. Disconnect your cabinet from its power supply and remove
all product from inside.
2. Open all doors and allow the cabinet to reach room temp-
erature. Remove all accessories (floor racks, drain plug
stopper, etc.) from inside and wash them with a baking
soda and warm water solution, wipe thoroughly with clean
water.
Dry all accessories completely with a soft clean cloth.
3. Once the cabinet has reached room temperature, wash the
inside and outside surfaces with a solution of warm water
and baking soda. Pay particular attention to the face of the
cabinet, as any residue or debris can impair the door seal.
For slightly more difficult cleanups, ammonia or vinegar in
warm water can be used. Wipe down thoroughly with a
damp cloth or sponge that has been soaked in clean water
