Section 2

NOTE: A manual fill valve is incorporated into the water

circuit to the carbonator tank. This valve can be used to

manually add water lost for any reason. Do not leave this

valve ON constantly, only use it for filling and topping off.

The water bath must be drained, flushed, and refilled

every six months.

2. Turn ON the switch labeled "Refrigeration". Allow

unit to run for about 15 minutes before proceeding to

step 3.

3. Turn ON the switch labeled "Agitator".

Note: Turn this switch OFF to perform any operations in

the water bath area.

With water bath water temperature of 65°F (18°C), ice

must begin to form on the evaporator coils in

approximately 2 hours. The unit will build a full ice bank

in approximately 4 to 6 hours (depending on ambient

water temperature).

4. Before turning on the carbonator or circulator switch,

verify that the pump box assembly has been

mounted and connected to the unit and the

appropriate syrup and water has been supplied.

5. Turn on the main water supply to the booster

assembly. Verify the booster is plugged in and that

the accumulator tank valve is open. (If the system

has an optional "Out-of-Syrup" device, verify that it is

unplugged.)

6. Verify the pump is running. Place the valve on the

right side of the pump box in the purge position until

all air bubbles have passed through the line. Turn

the valve back to "dispense". Plug the Out-of-Syrup

device power cord into an appropriate wall outlet at

this time (if supplied).

NOTE: Verify that the pump box holding tank is full

before proceeding.

7. Turn on the circulator and carbonator switches. The

carbonator must run for approximately 1 to 3

minutes and shut off. The circulator must run

continuously. Verify that water is returning to the

water bath through the return bulk head fitting.

Important

Wait until a thin layer of ice has begun to form on the

evaporator before proceeding any further.

8. Go to the tower(s) and brix the valves. Using a syrup

separator and volume cup, adjust the flow rate of the

carbonated water to two fluid ounces per second.

Then, using the separator and a brix cup, adjust the

syrup flow rate for a ratio of carbonated water to

syrup to 5 to 1.
