PRODUCT CARBONATION ADJUSTMENT

(see Figures 2 and 6)

Carbonation of dispensed product can also be varied to suit consumer preference by adjusting Unit carbonator secondary CO2 regulator as follows:

IMPORTANT: Carbonator tank secondary CO2 regulator must be adjusted 25-psi higher or more above product blender tanks secondary CO2 regulator pressure settings. Carbonated water and syrup pressures must be able to overcome and vent product blender tanks head pressures while tanks are filling with carbonated water and syrup. Carbonator tank secondary CO2 regulator not adjusted high enough will cause decreased flow of carbonated water into blender tanks, which will increase brix of dispensed product.

1.Remove Unit lower front access panel as instructed for access to carbonator secondary CO2 regulator with 100-psi gauge.

2.Observe pressure setting on carbonator secondary CO2 regulator gauge.

3.To lower CO2 pressure, loosen regulator adjusting screw lock nut. Turn adjusting screw to the left (counter- clockwise) until pressure gauge reads 15-psi below desired reading, then turn screw to the right (clockwise)

until gauge reads desired pressure. DO NOT SET CO2 REGULATOR PRESSURE BELOW 25-PSI HIGH-

ER THAN PRODUCT BLENDER TANKS CO2 REGULATORS ARE ADJUSTED TO (SEE PRECEDING IMPORTANT NOTE). Tighten adjusting screw lock nut after each adjustment.

4.Observe pressure setting on carbonator secondary CO2 regulator gauge.

5.To raise CO2 pressure, turn regulator adjusting screw to the right (clockwise) until gauge reads desired pressure. DO NOT SET PRESSURE HIGHER THAN 60-PSI. Make sure primary CO2 regulator on CO2 cylinder is set at 80 to 100-psi. Tighten adjusting screw lock nut after each adjustment.

6.Install lower front access panel on Unit.

CLEANING AND SANITIZING

DAILY CLEANING OF UNIT

Daily, or more often if necessary, wash all external surfaces of Unit with a mild soap solution. Rinse with clean water, then wipe dry with a clean soft cloth. DO NOT USE ABRASIVE CLEANERS. Remove and wash drip tray in mild soap solution, rinse with clean water, then install drip tray on Unit.

SANITIZING SYRUP SYSTEMS

NOTE: The Unit should be sanitized every 120 days following Sanitizer Manufacturer’s recommenda- tion. Use Chlor-Tergent (Oakite Products, Inc.) or equivalent sanitizer.

The Unit should be sanitized every 120 days and before and after storage periods following parent company requirements and sanitizer manufacturer’s recommendations. One or both syrup systems may be sanitized at one time for routine 120 days sanitizing requirements. The following sanitizing instructions use No. 1 syrup sys- tem as an example. No. 2 syrup system sanitizing instructions are identical to No. 1 syrup system with the ex- ception of using applicable system switches. Proceed as follows:

1.Press ‘‘OFF 2’’ switch to stop beater motor and refrigeration in No. 2 freeze cylinder, which is not to be de- frosted. ‘‘OFF 2’’ fault message will appear on message display.

2.Press ‘‘DEFROST’’ switch to start defrost cycle on No. 1 freeze cylinder. ‘‘DEFROST 1’’ message will ap- pear on message display as long as defrost cycle is in progress.

3.Immediately press ‘‘AUTO 2’’ control switch to restart beater in No. 2 freeze cylinder. Refrigeration in No. 2 cylinder will not be operating.
