TOPPER CABINET MAINTENANCE

PERIODIC CLEANING
Periodically wash all external surfaces of TOPPER cabinet, rinse with clean water, then wipe
dry with a clean soft cloth. DO NOT USE ABRASIVE TYPE CLEANERS.

CLEANING CONDENSER COIL

IMPORTANT:
compressor. Air is drawn in through grills on the top of the cooling unit, through
condenser coil and exhausted out grills on the top of unit. Restricting air circulation
through the cooling unit will decrease its cooling capacity.
NOTE: Cleaning condenser coil should be done during non-use periods.
1. Unplug refrigeration unit power cord from electrical socket.
2. Remove cover of unit.
3. Vacuum or use a soft brush to clean fins of condenser coil.
compressed air or C02 gas to blow through condenser fins.
performed after normal business hours to prevent dust contamination. A damp cloth on
backside of condenser coil will prevent some dust contamination
4. Replace cover.
S. Plug TOPPER power cord in electrical socket.
CHECKING / CHANGING WATER BATH
Periodically check water level in water bath. If it is low, more water should be added for
maximum product cooling. Before adding more water, water bath and ice bank should be
checked for excessive mineral deposit build up.
NOTE: The water in water bath should be changed and all components in water bath
should be cleaned as often as necessary to keep it clean. A convenient time to perform
this operation is when the system is being sanitized.
1. Unplug refrigeration unit power cord from electrical socket.
2. Remove cover from unit and hinge up refrigeration deck.
3. Look down into water bath (if necessary, use flashlight) and inspect water bath, ice
bank and all components for cleanliness. Water, ice bank and all components should be
clear and free of foreign particles. If ice bank is clear of foreign particles, it does not have
to be melted down. Proceed to step 10, if foreign particles are present in the ice bank,
proceed to step 4.
4. Siphon out water with short hose or pull out over flow standpipe.
5. Allow ice bank to melt. Hot water may be used to speed melting.
CAUTION: Never use an ice pick or other sharp instruments to remove ice from evaporator
coil. Such practice can result in puncture to the refrigeration circuit.
Air circulation through the condenser coil is required to cool the
