THEORY OF OPERATION A carbonator is a device designed to dissolve carbon dioxide gas (CO2) in

water, producing carbonated water. CO

2

gas is delivered through a regulator
to the carbonator tank. Simultaneously, plain water is pumped into the tank.
The CO

2 gas, under pressure, dissolves in the water and the result is

carbonated water. When the level of carbonated water reaches a
pre-determined point, the liquid level sensing device (inside the tank) signals
the liquid level control module which, in turn, shuts off the pump motor. As
carbonated water is drawn from the tank, the level of carbonated water will
drop. At a certain point, the liquid level sensing device recognizes that drop in
the level and turns on the pump motor which replenishes the amount of
carbonated water that has been taken out of the tank.

1. INSTALLATION

1.1 RECEIVING

A. Each unit is completely tested under operating conditions and thoroughly inspected before

shipment. At the time of shipment, the carrier accepts the unit and any claim for damage(s)
must be made with the carrier. Upon receiving units from the delivering carrier, carefully inspect
carton for visible indication(s) of damage. If damage exists, have carrier note same on bill of
lading and file a claim with the carrier.

B. Open the top of the carton. Remove interior packing. Carefully lift the Carbonator out of

carton.

C. Inspect for concealed damage(s) and if detected, notify delivering carrier and file claim.

1.2 SELECTING LOCATION

A. Select a level, well ventilated, accessible location convenient to water and electric supply. The

selected location should be able to withstand a load of 100 pounds (45.5 kg).

1.3 CONNECT WATER LINE TO PUMP

A. Connect Flexible Pressure Tubing, 3/8 inch ID or larger, from water supply to Pump Inlet using

a 3/8 inch SAE Female Swivel Nut (PN 01-0232) and Flare Seal Washer (PN 05-0017).
B. A Shutoff Valve should be installed in water line to Carbonator.
C. Water supply must provide a minimum flow rate of 125 GPH (473 LPH), and have a minimum

pressure of 25 PSIG (1.83 kg/cm

2

) and a maximum of 80 PSIG (5.62 kg/cm2). If water
pressure exceeds 80 PSIG (5.62 kg/cm2), install a Regulator (Lancer models are available) and
adjust to 50 PSIG (3.51 kg/cm

2

).

D. Off tastes and excessive silt, sand, or iron require that a water filter be installed in the water

line supplying the Carbonator. The water filter should be checked periodically, as required by
local conditions.

NOTE

Do not connect to a heated (hot) water source or a water source supplying soft water. This will
cause excessive foaming.

1.4 CONNECT CO

2 LINE TO TANK

A. Connect Flexible Pressure Tubing, 1/4 inch ID or larger from CO2 Regulator to the Tank Inlet

using a 1/4 inch SAE Female Swivel Nut and Flare Seal Washer.

B. CO

2 supply must have a Regulator (Lancer models are available) and Gauge (Lancer models

are available) adjustable from 0 to 150 PSIG (3.5 kg/cm2) minimum.

1.5 CONNECT CARBONATED WATER TO DISPENSING SYSTEM

A. Connect Flexible Pressure Tubing, 3/8 inch ID or larger, from Dispensing System to Outlet on

Tank, using a 3/8 inch SAE Female Swivel Nut and Flare Seal Washer.

B. If only one Carbonated Water Outlet on the Tank is used, the other Outlet must be capped with

a Stainless Steel Cap Nut (PN 01-0212) and Flare Seal Washer (PN 05-0017).

1.6 ELECTRIC POWER SUPPLY

W

ARNING

THIS UNIT MUST BE PROPERLY ELECTRICALLY GROUNDED TO AVOID POSSIBLE FATAL
ELECTRICAL SHOCK OR SERIOUS INJURY TO THE OPERATOR. THE POWER CORD IS
PROVIDED WITH A THREE PRONG GROUNDED PLUG. IF A THREE HOLE GROUNDED
ELECTRICAL OUTLET IS NOT AVAILABLE, USE AN APPROVED METHOD TO GROUND THE
UNIT.

A. The electric power supply must be a three prong, ground convenience outlet having the same

configuration as the power cord.

B. Outlet must have proper voltage, cycles and ampere ratings. See Carbonator Name Plate for

ratings.

NOTE

Do not plug into electrical outlet unless ratings on name plate agree with local current available.
