RECEIVING

Each unit is completely tested and inspected before shipment. At the time of
shipment, the carrier accepts the unit and any claim for damage must be made
with the carrier.

Upon receiving the unit(s) from the carrier, inspect the carton for visible damage.
If damage exists, have the carrier make a note on the bill of lading and file a
claim with the carrier.

UNPACKING

• Remove staples securing carton to pallet.

• Lift carton up and off of unit.

• Remove inserts and shipping bag.

• Open upper cabinet door and remove installation kit.

• Remove bolts securing unit to pallet.

• Lift unit off of pallet.

NOTE: Do not lay the unit on it’s side or back. This may cause vital oils

to drain from the compressor resulting in damage during start­up and consequently voiding the warranty.

MINIMUM 12”

AIR FLOW CLEARANCE

AIR FLOW CLEARANCE
MINIMUM 4”

COUNTER LOCATION

Select a location in a well ventilated area, close to a grounded electrical outlet. If
possible do not place the unit close to hot and/or steaming machines.

The minimum airflow clearance is: 4” (10.16 cm) in back and 12” (30.48 cm) on
top and open to the front.

IMPORTANT: Condenser air is drawn in from the bottom of the rear panel

and discharged out the top of the rear panel. Failure to
maintain clearance space will reduce capacity of the unit
and cause premature compressor failure.

Typically the dispenser is placed directly on the counter and a food grade
silicone sealant applied around the base. However, supplied with the dispenser
is a counter top sealing gasket. This eliminates the need for sealant and is much
easier to use.

WATER BATH

OVER FLOW

FILLING THE ICE BATH

The ice bath holds approximately 2 gallons (7.6 liters) of water. The fill tube is
located behind the front splash plate and capped with a 3/8” (0.95 cm) male flare
connector. Prior to attaching the water supply line to the dispenser, use it to fill
the ice bath by attaching it to the connector on the fill tube.

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.

Figure 3. Filling the Water 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.

WARNING:

CONNECTING WATER SUPPLY

The QST series Juice Dispenser is designed to dispense juice at a high flow
rate. It is very important 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 softener. It is the installer’s
responsibility to ensure that all water connections to the
dispenser are sized, installed with adequate backflow
protection and maintained to comply with Federal, State,
and Local Laws.

1. Secure the 3/8” (0.95 cm) swivel nut on the flexible supply tubing to the
water inlet located at the rear of the dispenser. Make sure that the flared
gasket is used (flared gasket is included with the installation kit).

Figure 4. Water Supply Connection

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. Water shut off outside the
unit is recommended.

This equipment must be installed to comply with the International Plumbing Code
of the International Code Council and the Food Code Manual 01 the Food and
Drug Administration (FDA). For models installed outside the U.S.A., you must
comply with the applicable Plumbing/Sanitation Code for your area.

Failure to comply could result in serious in jury, death or damage to the
equipment.

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 from all dispense valves.

NOTE: Some splashing may occur during this purge cycle.

PROGRAMMING THE PORTION CONTROL

If the 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-programmed to pour 16 ounces. To change the
pour sizes, please perform the following procedure.

Step Action

Simultaneously, press and hold Small and Extra Large (pitcher icon) buttons on

1

the Portion Control Module until the Refill light starts blinking. Release the but­tons. The blinking Refill light indicates the programming mode is active.

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

2

medium, large, or extra large). Hold the button in until the cup fills to the desired
portion, then release the button. Repeat the procedure for the remaining sizes.

After programming all the drink sizes, press and release the Cancel/Pour button to

3

return the Portion Control to the operational mode. The blinking REFILL light goes
off.

In the future, to change the portion size of the drinks, the individual sizes can be

4

adjusted by performing Step 2. It is not necessary to reprogram every size. Addi­tionally, the portion control has full memory retention in case of a power failure.

CANCEL/POUR BUTTON

To pour a drink without using a pre-programmed portion control size, simply
push and hold the Stop button. Release when the glass is full.
