setting to 12-psig maximum. Excessive pressure may cause low-calorie syrup carbonation resulting in foam.
WATER FLOW RATE
Refer to Installation Instructions provided with the dispensing station for dispensing valve water flow rate
adjustment instructions.
WATER-TO-SYRUP ‘ ‘RATIO’ ’ OF DISPENSED PRODUCT
Adjust the dispensing station dispensing valves for Water-to-Syrup ‘‘Ratio’’ of the dispensed product as
instructed in dispensing station Installation Instructions.
ADJUSTING WATER-COOLED REFRIGERATION SYSTEM VARIABLE WATER
REGULATOR
IMPORTANT: Water flow rate through the refrigeration cooling coil varies due to pressure change on
the high side of the refrigeration compressor, which influences opening and closing of the variable
water regulator (see Figure 9). The variable water regulator must be adjusted to maintain a 240-psi
refrigeration system high-side pressure. Adjust the variable water regulator as follows:
1. Disconnect electrical power from the Cooling Unit at the disconnect switch.
2. Remove the Cooling Unit left side panel and front grille.
3. Connect gauges to the high-pressure side of the refrigeration system.
4. Restore electrical power to the Unit at the disconnect switch.
5. Operate the refrigeration system with the gauges installed. After approximately 5 minutes of operation,
adjust the refrigeration cooling coil variable water regulator (see Figure 9) to maintain a 240-psi
refrigeration system high-side pressure. The adjustment screw is located on the end of the coil assembly
and must be turned to the right (clockwise) to decrease the pressure or to the left (counterclockwise) to
increase the pressure.
6. After the pressure adjustment has been completed, disconnect electrical power to the Cooling Unit at the
disconnect switch.
7. Install left side panel and front grille on the Cooling Unit.
8. Restore electrical power to the Cooling Unit at the disconnect switch.
