-for best performance, please maintain clearance of 3" on the back of the unit
-outdoor use may cause decreased efficiency and damage to the unit
3) Avoid installation in a high humidity and/or dusty area
-humidity could cause unit to rust and decrease effeciency of the unit
-dust collected on condenser coil will cause unit to malfunction. Clean the condenser at least
once a month with a brush or clean cloth
-malfunction due to dirty condenser will void warranty
4) Select a location away from heat and moisture-generating equipment
-high ambient temperatures will cause the compressor to overwork, leading to higher energy bills
and gradual breakdown of the unit
-malfuNction due to high ambient temperature will void warranty
ELECTRICAL
Please ensure that the required voltage of the compressor is being supplied at all times. Low or high
voltage can detrimentally affect the refrigeration unit and thereby void its warranty.
All units should be plugged into a grounded and properly-sized electrical outlet with appropriate
overcurrent protection. Please refer to the electrical requirements on the unit serial tag located inside the
unit. Please make sure that your unit has its own dedicated outlet. Do not use an extension cord.

TEMPERATURE CONTROLS
The temperature controls are factory-set to maintain an average temperature of 38 F in refrigerators and 0
F in freezers. To maintain a different temperature, simply adjust the control knob located inside the unit.
To decrease the temperature (colder), turn clockwise. To increase the temperature (warmer), turn
counter-clockwise - see diagram

READING
LOADING PRODUCT
Shelves have been factory-installed for your convenience. Before loading shelves, please be sure that all
shelf clips are completely fastened in their correct locations. It is important that all shelves rest completely
level before stocking your cabinet with product.
In order to maintain correct air flow inside the unit, please be sure to leave two to four (2 to 4) inches of
space between the back wall and stored product. Blocking the evaporator fans will result in a warmer
cabinet temperature, and ultimately compressor failure.
DEFROST SYSTEMS
Refrigerator coils are kept below the freezing point (32 F). During compressor down-time, the evaporator
fan continues to circulate air through the evaporator coil. This air circulation raises the coil temperature
above the freezing point, melting any accumulated frost. Run-off water is drained into the evaporator pan
and evaporated. **Freezer coils are defrosted electrically.** Automatic defrost timers are built-in to the
refrigeration system and may not be adjusted. The defrost timers automatically initiate at pre-set intervals
and for a pre-determined duration.
**PLEASE NOTE: Excessive door openings should be avoided in order to maintain cabinet temperature
and to eliminate the possibility of coil freeze-up.**
LOADING FOOD PANS
Pizza prep units and sandwich prep units are designed to function with all pans in place, even if some
pans are to be left empty. For maximum food freshness, fill the pans only with an amount that can be
used in a specific usage period. During non-use, please close the insulated lid cover.

REGULAR MAINTENANCE
CLEANING THE CONDENSER COIL
For efficient operation, it is important that the condenser surface be kept free of dust, dirt, and lint.
ColdTech recommends cleaning the condenser coil and fins at least once per month. Clean with a
commercial condenser coil cleaner, available from any kitchen equipment retailer. Brush the condenser
fins from top to bottom, not side to side. After cleaning, straighten any bent condenser fins with a fin
comb.
CLEANING THE FAN BLADES AND MOTOR
If necessary, clean the fan blades and motor with a soft cloth. If it is necessary to wash the fan blades,
cover the fan motor to prevent moisture damage.
CLEANING THE INTERIOR OF UNIT
When cleaning the cabinet interior, use a solvent of warm water and mild soap. Do not use steel wool,
caustic soap, abrasive cleaners, or bleach that may damage the stainless steel surface.
Wash door gaskets on a regular basis, preferably weekly. Simply remove door gasket from the frame of
the door, soak in warm water and soap for thirty (30) minutes, dry with soft cloth, and replace. Check door
gaskets for proper seal after they are replaced.
Periodically remove the shelves and pilasters from the unit and clean them with mild soap and warm
water. To remove the pilasters, first remove the shelves and shelf brackets. Then, simply lift the pilaster
up and out.
WARNING
Disconnect power cord before cleaning any parts of the unit.
