CHECKING / CHANGING WATER BATH
Semi-Annually 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 lid from unit.
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. WARM NOT 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.
6. Use fiber brush and carefully clean mineral deposit from all components.
8. Wash evaporator coil with a mild soap solution. Copper cleans well with mild
solution of citric acid (1 cup of citric acid for 2 gallons of water). Stainless steel
cleans well with carbonated water. Then rinse with clean water.
9. Rinse out water bath with clean water until water running out of siphon hose is
clean.
9. Insert standpipe in drain hole
10. Fill water bath to top of standpipe.
11. Replace lid.
12. Plug refrigeration unit power cord in electrical socket.
