1.Disconnect electrical power from Cooling Unit at disconnect switch.

2.Close shutoff valve in plain water inlet supply line.

3.Note pressure setting on carbonator CO2 regulator, then turn regulator adjusting screw to the left (counterclockwise) until regulator gage reads 0-psi.

4.Remove two screws securing Cooling Unit top cover,then remove cover for access to carbonators water pumps.

CAUTION: Condenser Coil and Fan Assembly condenser coil must be cleaned every 30 days. Excessive accumulation of debris on condenser coil will restrict cooling air flow through coil and cause coil and refrigeration system overheat. Operating refrigeration

system in overheated condition will eventually result in Cooling Unit compressor failure.

5.If left-side (facing front switch side) of Cooling Unit is obstructed, unit will have to be pulled out for removal of left-side panel for access to carbonator tanks and tanks carbonated water outlet lines liquid single check valves.

6.Remove Cooling Unit left-side panel.

7.Loosen carbonator water pump screen retainer, then pull screen retainer and strainer screen from water pump.
