GENERAL INFORMATION
(Continued)
For maximum efficiency, the unit should be defrosted whenever frost layer on the interior reaches a
thickness of 1/8 inch. Never scrape the walls to remove frost.
P.O.P. Refrigerated Drawers are designed to be used as holding cabinets at the point of preparation.
They are not a satisfactory substitute for walk-in type coolers or freezers.
Because of this, they should never be used to cool foods down to storage temperatures. Foods placed
in the drawers should be precooled or frozen in your walk-in storage unit which has the cooling
capacity for this purpose.
The process of mechanical refrigeration has a natural tendency to dehydrate the air being cooled.
This dry air, in turn, will tend to draw moisture from unwrapped foods. It is important, therefore, that
unwrapped meats and vegetables not be stored in holding drawers for periods exceeding 24 hours.
Never put more product in the drawers than will be turned over in one business day. It is a good idea to
remove all pans of food from the drawers at the end of the day, cover them, and return them to the
walk-in storage cooler of freezer. The result will be not only a fresher, tastier product, but you will find,
that your P.O.P. drawers require defrosting less often.
Some Tips on Food Storage in P.O.P. Refrigerated Drawers:

PROBLEM SUGGESTED CAUSE
1. If unit has been turned on side or upside down when being removed from packaging, let stand
in upright position for one hour or more before turning on.
2. Unit should be level on all sides.
3. This unit is to be connected only to a 120V, 60 Hz grounded power supply.
4. Disconnect unit from power supply before servicing.
5. This unit is equipped with a standard refrigeration compressor located to the side or bottom of
the unit. In order to have efficient operation of the refrigeration compressor, the condenser coil
must be kept clean. Vacuum the face of the coil regularly. The coil is located behind the front
grill. The grill is removable after removing the two screws securing it.
6. The temperature dial is also located behind the front grill. It regulates the temperature of the
unit from approximately 30°F to 45F (-1°C to + 7°C) and turns off unit for defrosting.
7. For maximum efficiency, the unit should be defrosted whenever frost layer on the interior
reaches a thickness of 1/8 inch. Never scrape the walls to remove frost.
