16. Lubricate O-RING (item 5) with water to facilitate faceplate installation. Position O-RING (item 5) on
FACEPLATE (item 8). Install faceplate on Unit so dispensing valve spout faces down. (MAKE SURE
FEMALE END OF THE BEATER IS PLACED OVER THE FACEPLATE STAINLESS-STEEL STUD AND
BUSHING BEFORE PUSHING THE FACEPLATE INTO POSITION ON ITS FOUR THREADED
MOUNTING STUDS). Tighten hex nuts until faceplate touches freeze cylinder all around flange. CAUTION
- DO NOT OVERTIGHTEN HEX NUTS.
17. Turn dispensing valve spring housing to the left (counterclockwise) to put tension on torsion spring, then
tighten hold-down plates to secure spring housing.
18. Test dispensing valve to make sure it closes by itself when lever is released. If not, readjust torsion spring
tension.
19. Sanitize syrup system as instructed in CLEANING AND SANITIZING.
20. Return Unit to operation.

CLEANING CONDENSER COIL

(see Figure 7)

UNIT WITH AIR-COOLED REFRIGERATION SYSTEM

NOTE: Circulating air, required to cool the refrigeration system condenser coil, is drawn in through
louvers on front and exhausted out through louvers on sides and back of Unit. Restricting air
circulation through Unit will decrease its cooling efficiency.
Periodically clean condenser coil as follows:
1. Press ''OFF 1'' and ''OFF 2'' switches on Unit control panel to stop refrigeration system and beater motors.
2. Remove condenser coil access panel and and condenser coil air filter(s).
3. Clean condenser coil and condenser coil air filter(s) with vacuum cleaner, low pressure compressed air, or
a soft brush.
4. Install condenser coil air filter(s) and condenser coil access panel by reversing removal procedure.
5. Press ''AUTO 1'' and ''AUTO 2'' switches on Unit control panel to start refrigeration system and beaters
motors.

UNIT WITH WATER-COOLED REFRIGERATION SYSTEM

The high-pressure cutout switch, located inside the lower control box (see Figure 17), will shut the Unit
refrigeration system down when overheated (high head pressure) caused by lack of cooling water. After the
problem has been corrected and the head pressure has decreased, the reset button on the high-pressure cutout
switch must be pressed to restart the refrigeration system.

ADJUSTING PLAIN WATER PRESSURE REGULATOR

(see applicable Figure 2 or 3 and 12)
Carbonator(s) plain water inlet adjustable water pressure regulator is factory adjusted to 45 psi and should not
be readjusted.
