8. Open Beverage Control Panel Assembly water
inlet supply line shutoff valve.
9. Plug carbonator(s) and the Water Pressure
Booster system power cords into electrical
outlets.
Checking Water Tank Air, CO
2
, or Nitrogen Gas
Pressure
NOTE: The Water Pressure Booster system water
tank must be completely drained before
proceeding to check and if necessary, pressurize
the tank with the proper amount of commercially
dry air, CO
2
, or nitrogen gas pressure. Proceed as
follows:
1. Unplug carbonator(s) and Water Pressure
Booster system power cords from electrical
outlets.
2. Close Beverage Control Panel Assembly water
inlet supply line shutoff valve.
3. Close plain water outlet shutoff valve Post–Mix
Dispenser plain water line is connected to.
4. Disconnect Post–Mix Dispenser plain water line
from shutoff valve.
5. Place bucket under shutoff valve. Open shutoff
valve and allow water to be purged from Water
Pressure Booster System water tank, then close
valve.
6. Note service valve (see applicable Figure 3, 4, 5,
or 6) on bottom of the Water Pressure Booster
system water tank. The water tank must be
pressurized to 40 5–PSI (2.76 .34 Bars) with
commercially dry air, CO, or nitrogen gas
pressure. Check and make sure water tank is
properly pressurized.
7. Open Beverage Control Panel Assembly water
inlet supply line shutoff valve.
8. Place bucket under Post–Mix Dispenser shutoff
valve. Open valve and allow water to flow until a
good stream of water flows from valve, then
close valve.
9. Reconnect Post–Mix Dispenser plain water line
to shutoff valve.
10. Plug both carbonators and Water Pressure
Booster System power cords into electrical
outlets.
Adjusting Pressure Switch ‘‘CUT OUT’’ (pump stops)
and‘‘CUT IN’’ (pump starts).
NOTE: The Water Pressure Booster system water
tank and the water system surge tank must be
completely drained and make sure they are
properly pressurized with commercially dry air,
CO
2
, or nitrogen gas pressure before checking
the water pump ‘‘CUT–IN’’ (pump starts) and
‘‘CUT–OUT’’ (pump stops). Proceed as follows:
1. Unplug carbonator(s) and Water Pressure
Booster system power cords from electrical
outlets.
2. Close Beverage Control Panel Assembly water
inlet supply line shutoff valve.
3. Close water manifold plain water shutoff valve
Post–Mix Dispenser plain water line is connected
to. Disconnect water line from shutoff valve.
4. Place bucket under shutoff valve. Open shutoff
valve and allow water to be purged from water
system surge tank and Water Pressure Booster
System water tank. DO NOT CLOSE SHUTOFF
VALVE AT THIS TIME.
5. Note service valve on bottom of Water Pressure
Booster system water tank and water system
surge tank. The Water Pressure Booster system
water tank must be checked to make sure it is
pressurized to 40 ± 5–PSI (2.76 ± .034 Bars)
and the water system surge tank is pressurized
to 12 ± 2–PSI (.83 ± .14 Bars) with commercially
dry air, CO
2
, or nitrogen gas pressure.
6. Close Post–Mix Dispenser water outlet shutoff
valve, then open Beverage Control Panel
Assembly plain water inlet supply line shutoff
valve.
7. Place bucket under Post–Mix Dispenser water
outlet shutoff valve. Open shutoff valve and allow
water to flow until water surge tank and Water
Pressure Booster System water tank are filled
and a good stream of water flows from shutoff
valve, then close valve.
CAUTION: To avoid damage, do not exceed the
maximum allowable system pressure of 85 ±
5–PSI (5.86 ± .35 Bars).
WARNING: Adjustment nuts are located
close to the high voltage terminals on
the pressure switch. To prevent possible electri-
cal shock, use an insulated 3/8 nut–driver to
make adjustments. Only qualified personnel
should perform adjustments on pressure
switch.
