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.Hold appropriate container under bleeder valve on air reservoir tank (see Figure 7).

2.Open valve to allow water (condensation) to be purged from reservoir tank and until only air comes out of valve, then close valve.

CLEANING OPTIONAL SYRUP LINES STRAINERS (SEE FIGURE 15).

NOTE: Use ONLY LUKEWARM WATER. Hot water destroys the chlorine power of the sanitizer and cold water does not allow the sanitizer to dissolve. Lukewarm is warm but not HOT, approximately body temperature.
