CARBONATOR ASSEMBLY SERVICE AND MAINTENANCE

WARNING: The carbonator water pump water inlet strainer screen and liquid double check valve must be inspected and ser- vice at least once a year under normal circum- stances, and after any disruptions (plumbing work, earthquake, etc.) to the water supply sys- tem that might cause turbulent (erratic) flow of water through the system. A carbonator water pump with no screen or a defective screen in strainer would allow foreign particles to foul liq- uid double check valve. CO2 gas could then ba ck flow into water system and create a health

hazard in the water system

Refer to manual provided with carbonator assembly for service and maintenance instructions.

ADJUSTING PRIMARY CO2 REGULATORS

(see Figure 7).

System Connected to Bulk CO2 Supply

Adjust primary CO2 regulator on bulk CO2 supply tank to 105–PSI (7.24 Bars)

System Connected to Two–Fifty Pound CO2 Cylinders

Adjust two primary CO2 regulators to 105–PSI (7.24 Bars)

ADJUSTING SECONDARY CO2

REGULATORS

Sugar–Base Syrup Tanks CO2 Regulator

Adjust sugar–base syrup tanks CO2 regulator with 100–PSI (6.9 Bars) gauge on secondary CO2 regulator assembly to 60–PSI (4.14 Bars).

Diet–Syrup Tank CO2 Regulator.

CHECKING PLAIN WATER SYSTEM SURGE TANK AIR, CO2 OR NITROGEN GAS PRESSURE (see applicable Figure 3, 4, 5, or 6).

NOTE: The plain water surge tank must be completely drained before proceeding to check and if necessary, pressurize the tank with the proper amount of ‘‘commercially dry air, CO2, or nitrogen gas pressure. Proceed as follows:

1.Unplug carbonator(s) and if applicable, the optional Water Pressure Booster system power cords from electrical outlets

2.Close Beverage Control Panel Assembly main 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 surge tank. DO NOT CLOSE VALVE AT THIS TIME.

6.Note: service valve on bottom of the water

system surge tank. The surge tank must be pressurized to 12 ± 2–PSI (.83 ± .14 Bars) with

commercially dry air, CO2, or nitrogen gas pressure. Check and make sure surge tank is properly pressurized.

7.Close Post–Mix Dispenser plain water outlet shutoff valve.

8.Open Beverage Control Panel Assembly main water inlet supply line shutoff valve.

9.Plug the carbonator(s) and if applicable, the optional Water Pressure Booster system power cords into electrical outlet.

10.Place bucket under Post–Mix Dispenser plain water outlet shutoff valve. Open shutoff valve until a good stream of water flows from valve, the close valve.

11.Reconnect Post–Mix Dispenser water line to shutoff valve.

SERVICING OPTIONAL WATER PRESSURE BOOSTER SYSTEM

(see applicable Figure 3, 4, 5, or 6)

Servicing Water Pump Water Inlet Strainer Screen

1.Unplug carbonator(s) and the Water Pressure Booster system power cords from electrical outlets.
