COOLING UNIT EQUIPPED WITH WATER-COOLED REFRIGERATION SYSTEM
The Cooling Unit equipped with a water-cooled refrigeration system requires no cleanning of it’s condenser coil.
COOLING UNIT MAINTENANCE
PERIODIC CLEANING
Periodically operate the carbonator tank relief valve.
Periodically wash all external surfaces of the Cooling Unit, rinse with clean water, then wipe dry with a clean soft
cloth. DO NOT USE ABRASIVE TYPE CLEANERS.
CLEANING CONDENSER COIL (COOLING UNIT EQUIPPED WITH INTERNAL
CONDENSER COIL)
(see Figure 4)
CAUTION: The Cooling Unit condenser coil must be cleaned every 30 days. Excessive
accumulation of dust, lint, and grease on the condenser coil will restrict air flow through
the coil which will cause the refrigeration system to overheat.
Note: The Cooling Unit end access panel must be removed for access to the condenser coil.
Excessive accumulation of dust, lint, and grease on the condenser coil will restrict air flow through the coil and
cause a loss of cooling efficiency. Vacuum or use a soft brush to clean the condenser coil. If available, use
low-pressure compressed air to clean the coil.
CHECKING ICE WATER BATH
(see applicable Figure 4 or 5)
A gurgle heard from the Cooling Unit indicates water level in the water tank is low and more water should be
added to the tank for maximum product cooling. The ice water bath and the ice bank should be checked for
cleanliness and the water tank coils should be checked for excessive mineral deposit build-up as follows:
1. Disconnect electrical power from the Cooling Unit at the disconnect switch.
2. Remove two screws securing the Cooling Unit top cover, then remove the cover.
3. Using a flashlight, inspect the ice water bath and the ice bank for cleanliness.The ice water bath should be
clear and the ice bank should be free of foreign particles.
4. If cleaning of the water tank is necessary, refer to CHANGING ICE WATER BATH in this section.
5. Fill the water tank with clean water until water starts flowing from the water tank overflow hose. USE LOW
MINERAL CONTENT WATER WHERE A LOCAL WATER PROBLEM EXISTS.
6. Install Cooling Unit top cover and secure with four screws.
7. Restore electrical power to the Cooling Unit at the disconnect switch.
