CLEANING WATER TANK
(see Figure 6)
1. Unplug the Unit power cord from electrical outlet.
2. Close shutoff valve in plain water source line connected to the Unit.
3. Remove two screws securing the Unit front access panel, then remove the panel.
4. Extend the water tank drain hose (located on front of Unit) to a waste container or floor drain. Remove plug
from end of the drain hose and allow the water tank to drain.
5. Remove screw securing the hood, then lift the hood straight up to remove from the Unit.
6. Unit With Integral (Built-In) Cold Carbonator. (see Figures 2 and 6)
A. Disconnect plain water source line from Unit double liquid check valve assembly inlet.
B. Disconnect carbonator water pump plain water outlet line from carbonated water tank plain water inlet
line.
7. Unplug the drop-in refrigeration assembly and electric dispensing valve power cords at connectors on front
of the Unit.
CAUTION: The ice bank around the drop-in refrigeration assembly evaporator coils must be
completely melted before attempting to lift the drop-in refrigeration assembly up and out of
the Unit lower cabinet assembly. Attempting to lift the drop-in refrigeration assembly and
ice bank together up out of the Unit lower housing assembly may cause damage to the evaporator
coils.
CAUTION: Never use an ice pick or other instrument to remove ice from the drop-in
refrigeration assembly evaporator coils. Such practice can result in a punctured
refrigeration circuit.
8. Allow the ice bank around the drop-in refrigeration assembly evaporator coils to completely melt. Hot water
may be used to speed up the melting process.
9. Very carefully, lift the drop-in refrigeration assembly up and out of the Unit lower housing assembly..
10. Use a fiber brush and carefully clean mineral deposit build-up from the agitator motor shaft and the ice
bank sensing bulb.
11. Wash inside of the water tank and the drop-in refrigeration assembly evaporator coils, then rinse with clean
water.
12. Install plug in end of the water tank drain hose.
13. Very carefully, install drop-in refrigeration assembly in Unit lower housing assembly by reversing the
removal procedure.
14. Unit With Integral (Built-In) Cold Carbonator. (see Figures 2 and 6)
A. Connect carbonator water pump plain water outlet line to carbonated water tank plain water inlet line.
B. Connect plain water source line to Unit double liquid check valve assembly inlet.
15. Fill the water tank with clean water until water runs out of the water tank overflow hose. USE
LOW-MINERAL-CONTENT WATER WHERE A LOCAL WATER PROBLEM EXISTS.
16. Plug Unit power cord into electrical outlet. The refrigeration system will start after a 2-minute time delay.
