ADJUSTING CARBONATOR TANK LIQUID LEVEL
The carbonator tank liquid level (pump cut-in and cut-out) was adjusted at the factory and should require no fur-
ther adjustment. However, if incorrect setting is suspected, check and make necessary adjustments as follows:
1. Remove Unit back and side panels as instructed for access to carbonator and carbonated water volume
sample valve (see Figure 6 and 14).
2. To check carbonator tank total fill; allow carbonator water pump motor to operate and fill tank with carbon-
ated water. After pump cycles off, disconnect electrical power from Unit.
3. Using container graduated in ounces, open carbonator carbonated water sample valve and completely
drain carbonator tank into container. Total carbonated water volume dispensed should be 40 to 58-ounces
maximum.
4. If total carbonated water dispensed is below 40 ounces, loosen screw securing level control switches ac-
tuator bracket (see Figure 14 ) and move actuator bracket up slightly. If more than 58 ounces, maximum of
carbonated water was dispensed, move actuator bracket down, then tighten screw. MAKE ADJUST-
MENTS IN SMALL INCREMENTS.
5. Connect electrical power to Unit and allow carbonator tank to fill with water until water pump cycles off.
6. Repeat steps 2 through 5 preceding as many times as necessary until correct carbonated water volume
adjustment is achieved.
