Slowly open the water shut off valve and fill the ice bath until water trickles from the overflow. This

is the quickest and easiest way to fill the ice bath.

Once the ice bath is full, store the fill tube in the vertically recessed holder. The fill tube can now be

used as a “sight glass” to monitor the water level in the ice bath.

CONNECTING WATER SUPPLY

The QST series Juice Dispenser is designed to dispense juice at a high flow rate. It is very impor-

tant that the incoming water line be dedicated for use by the dispenser only and does not have

other machines connected which could cause a water surge, (i.e., a dishwasher, coffee maker,

etc.).

IMPORTANT: The water supply should be consistent with proper water quality

standards (neutral pH of 7.0 to 8.0), and should not be connected to a water soften-

er. It is the installers responsibility to ensure that all water connections to the dis-

penser are sized, installed, and maintained according to Federal, State, and Local

Laws.

1. Secure the 3/8” (0.95 cm) swivel nut on the flexible supply tubing to the wa-

ter inlet located at the rear of the dispenser. Make sure that the flared gas-

ket is used (tubing and flared gasket are included with the installation kit).

2. When securing flare nut, use a backup wrench on the male side of the inlet

fitting (unit side) to prevent twisting of the copper tube inside the unit and/or possible damage

to the water strainer/solenoid. A water shut off outside the unit is recommended.

ELECTRICAL

A minimum of 15 amps electrical service is needed for 120VAC power supply.

PRIMING/FLUSHING WATER SYSTEM

To properly prime the unit with water and remove air pockets in

the system, open the cabinet door and make sure that all the

valve levers are in the “Dispense” position.

Close the door and press the dispense button for a

few seconds. Repeat until a steady flow of water is observed flowing from all dispense

valves.

NOTE: Water splashing may occur during this purge cycle.

PROGRAMMING THE PORTION CONTROL

If your dispenser has optional portion controls, they have been pre-programmed from the factory

to pour 7, 12, and 16 ounce drinks. The “extra large” (pitcher icon) size has also been pre-pro-

grammed to pour 16 ounces. To change the pour sizes, please follow the instructions below:

1. Simultaneously, press and hold “small” and “extra large” push button switches on the

Portion Control Module until the “Refill” light starts blinking. Release the switches.

The blinking Refill light indicates the programming mode is active.

2. Place the cup under the dispense nozzle and push the selected size button (small,

medium, large, or extra large). Hold the button in until the cup fills to the desired por-

tion, then release the button. Repeat the above procedure for the remaining sizes.
