D. Pull up on the carbonated water tank relief valve ring protruding up through hole in
the drop-in refrigeration deck (see Figure 8) to bleed off all pressure from the water
tank.
E. Disconnect plain water inlet and outlet lines from the carbonator water pump.
5. Extend the water tank drain hose to a waste container or floor drain. Remove plug from

7. Very carefully, lift the drop-in refrigeration assembly up and out of the Unit.
!
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. Use a fiber brush and carefully clean mineral deposit build-up from the agitator motor
shaft and the ice bank sensing bulb.
9. Wash inside of the water tank and the drop-in refrigeration assembly evaporator coils,
then rinse with clean water.
10. Install plug in end of the water tank drain hose.
11. Unit with integral (built-in) carbonator.
IMPORTANT: For proper alignment when lowering drop-in refrigeration assembly
into the Unit lower housing, steel tube welded on top of the carbonated water tank
must align with alignment funnel fastened into top of the refrigeration assembly
deck. The carbonated water tank ground wire (green with yellow stripe) must also
be routed up through hole in the refrigeration assembly deck and be connected to
mating ground wire connector on top of the refrigeration assembly deck. Failure to
connect the carbonated water tank ground wire will cause erratic operation of the
carbonator water pump motor.
