7. Cooling Unit with Water-Cooled Refrigeration System.
IMPORTANT NOTICE
Waterflowratethrough therefrigeration coolingcoil variesdueto pressurechangeonthe highside
of the refrigeration compressor which influences opening and closing of the variable waterregula-
tor (see Figure 9). The variable water regulator must be adjusted to maintain 240-psi refrigeration
high-side pressure.
Adjust the variable water regulator (see Figure 9) to maintain 240-psi refrigeration high-side pressure as
instructed in the SERVICE AND MAINTENANCE section of this manual.
8. Place the CARBONATOR MOTOR power switch in the ‘‘ON’’ position.
9. Place the REFRIGERATION power switch in the ‘‘ON’’ position. The agitator motor and the carbonator
pump motor only will start and fill the Hydro BoostR coil with plain water. APPROXIMATELY 2-1/2
MINUTES AFTER THE CARBONATOR PUMP MOTOR HAS STARTED, THE REFRIGERATION
COMPRESSOR AND THE COMPRESSOR COOLING FAN WILL START.
NOTE: As the ice bank forms in the water tank, water expansion will take place and excess water will
escape through the water tank overflow hose to the permanent floor drain.
The Cooling Unit will begin forming an ice bank and the refrigerated Hydro BoostR coil will also be chilling the
water. When full ice bank has been formed, the Cooling Unit compressor and the compressor cooling fan will
stop but the agitator motor will continue to operate circulating ice water bath in the water tank.
10. Dispense from the dispensing station until carbonated water appears at the dispensing valve which
indicates the Cooling Unit plain and carbonated water systems have been filled.
11. Place the CIRCULATING MOTOR power switch in the ‘‘ON’’ position.The Circulating pump will start and
begin circulating carbonated water in the carbonated water circulating system as explained in SYSTEM
THEORY OF OPERATION in GENERAL INFORMATION SECTION.
12. Dispense carbonated water from the dispensing valve to make sure all air has been purged from the
system.
13. If the Cooling Unit plain water outlet line has been connected to a dispensing station dispensing valve,
dispense from the valve until all air has been purged from the plain water system.
14. Adjust the soft drink tanks secondary CO

regulators (see Figure 2) as follows:

Adjust sugar syrup soft drink tanks secondary CO

regulator at 40-psig for syrup lines up to 10-feet in length
plus one pound for each additional length of 10-feet, plus one pound for each 2-feet of vertical lift. For example:
if syrup line total length is 30-feet and total vertical lift is 6-feet, then 40-psig + 2-psig (1-pound for every 10-feet
of length over 10-feet which is 20-feet) + 3-psig (1-pound for every 2-feet of vertical lift which is 6-feet); total
equals 40 + 2 + 3 = 45-psig CO

regulator setting.
Low-Calorie (diet) Syrup Soft Drink Tank CO
2
Regulator.
Adjust low-calorie (diet) soft drink tank secondary CO
2
regulator for low-calorie drink at 10-psig for syrup lines
up to 30-feet in length. Syrup lines longer than 30-feet in length may require a slightly higher CO
2
regulator
setting to 12-psig maximum. Excessive CO
2
pressure may cause low-calorie syrup carbonation resulting in
foam.
IMPORTANT: The syrup systems must be sanitized as instructed before syrup is connected into the
syrup systems.
