Note: The DIFFERENTIAL adjustment (20–psi) between ‘‘CUT–IN’’ (water pump starts) and ‘‘CUT–OUT’’ (water
pump stops) has been adjusted at the factory and should require no further adjustment. Should differential
adjustment become necessary, turn DIFFERENTIAL ADJUSTMENT nut clockwise to increase differential or turn
nut counterclockwise to decrease differential.
FIGURE 15. PRESSURE SWITCH ADJUSTMENT
8. Using 5/16 nutdriver, remove nut securing
pressure switch cover, then remove cover.
Note: Water pressure gauge to be observed when
checking ‘‘CUT–OUT’’ (water pump stops) is
located just above the water filters. Observing the
water pressure gauge, ‘‘CUT–OUT’’ (water pump
stops) should occur at 85 ± 5–PSI (5.86 ± .35
Bars).
9. Plug Water Pressure Booster System power
cord into electrical outlet.
10. Open Post–Mix Dispenser water outlet shutoff
valve and discharge water into bucket until pump
‘‘CUT– IN’’ (pump starts) occurs, then close
valve. Pump ‘‘CUT–OUT’’ should have occurred
at 85 ± 5–PSI (5.86 ±.35 Bars). If pump
‘‘CUT–OUT’’ was not correct, refer to Figure 15
and turn ‘‘CUT–OUT’’ adjustment nut to the right
(clockwise) for higher pressure or to the left
(counterclockwise) for lower pressure.
11. Repeat step 10) preceding and adjust until
proper pump ‘‘CUT–OUT’’ occurs.
12. Install pressure switch cover and secure with
nut.
13. Re–connect Post–Mix Dispenser plain water line
to Water manifold water shutoff valve.
14. Plug carbonator(s) power cord(s) into electrical
outlet.
SERVICING OPTIONAL AIR COMPRESSOR
ASSEMBLY AND AIR SYSTEM
MAINTENANCE
Air Compressor Maintenance.
Air compressor assembly air filter must be cleaned or
replaced with replacement air filter (P/N 111421–000)
every 30 to 60 days or more often, depending upon
environmental conditions.
Purging Air Reservoir Tank (Weekly)
IMPORTANT: To prevent water (condensation)
from entering system, water must be purged from
air reservoir tank once a week.
1. Open valve to allow water (condensation) to be
purged from reservoir tank and until only air
comes out of valve, then close valve.
WATER FILTERS REPLACEMENT
Refer to Water Filtration System manual for water
filters replacement instructions.
The syrup systems should be sanitized every
90–days using Chlor–Tergent (Oakite Products, Inc.)
or equivalent sanitizer. Refer to manual provided with
the Post–Mix Dispenser for sanitizing instructions.
