The Quest Juice Dispenser uses an ice/water bath system to cool both the potable water supply and the
concentrate cabinet.
To achieve cooling capabilities we use an agitator/recalculating pump and motor. This cools the stainless
steel water coils and circulates the cold water through a heat exchanger to cool the cabinet. This gives us
colder drinks for longer periods of time and eliminates the need to have to defrost the cooling cabinet.
A lighted merchandiser is standard.

SYSTEM DETAILS
WATER
Water Quality
Water quality has an affect on juice dispensing systems.
• odor
• taste
• clarity/foaming
Water filtration is recommended to assure the best beverage taste.
Water Flow
Inlet water pressure should be regulated to 45 to 50 psi max. (3.1 bar) to prevent damage to pump tubing. Minimum flowing pressure must be 20psi.
Flow Rates
Adequate water flow is necessary and must be at least 3.0 ounces per second (89ml) at the inlet to the
unit.
CONCENTRATE
•
Concentrate should be stored frozen and put into a cooler 72 hours before use. Rapid cooling, such
as in a sink of hot water, adversely affects flavor and leads to service calls.
•
Proper loading of concentrate is important. Improper loading is a major source of service calls.

clean water, lubricate the O-ring, and replace nozzle.
•
Flushing daily and sanitizing weekly is recommended.
SETTING
THE
B RIX
•
A refractometer must be used to measure the post-mix brix.
•
Ratio adjustment can be set with a concentrate separator and ratio cup, see Brixing Procedure.
•
Ratios are sometimes set by taste but this is not recommended.

KEY THINGS TO K NOW / DO
•
Work Safely! Always unplug/disconnect the power to the dispenser before servicing, and get help lifting the unit if it must be removed from the counter.
•
Make certain that the water line has adequate pressure at all times!
•
Learn to use a good quality volt-ohm meter. Proper electrical trouble shooting is impossible without it!
•
40-50 PSI dynamic water pressure measured at the dispenser inlet with 3.0 ounces a second. Water
pressure must not exceed 80 lbs static with a minimum flowing pressure of 30 PSI.
•
Never leave the Dispense/Flush lever in the Flush position, it can cause the pump tubing to burst.

INSTALLATION
COUNTER LOCATION
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.
FILLING THE ICE B ATH
The fill tube is located behind the splash panel. Use the water supply line to fill the ice bath before connecting it to the unit.
Remove the 3/8” cap from the fill tube/sight glass to begin filling the ice bath. Replace the cap when finished filling the ice bath. Lock it in place with its holder.

Level
Cabinet
drain outlet
Water bath
overflow
IMPORTANT: Fill the water bath slowly until it runs out
the overflow. Failure to do so can cause back pressure and improper water level. ALWAYS FILL WITH
THE UNIT UNPLUGGED.
Replace the cap TIGHTLY when finished filling the water bath. Lock it in place with its holder.
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 installers responsibility to ensure
that all water connections to the dispenser are sized, installed, and maintained according to Federal,
State, and Local Laws.
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 (tubing and
flared gasket are included with the installation kit).
IMPORTANT: 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.
PRIMING/FLUSHING WATER S YSTEM
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.
Dispense/
Flush Lever
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.

CONCENTRATE HANDLING & LOADING
It is recommended that the concentrate be thawed in a refrigerated 35°F-40°F (1.6°C-4.4°C) compartment for a minimum of 48 hours prior to loading into the Quest Juice Dispenser.
WARNING: Concentrate must be completely thawed and within the temperature range of 35°F40°F (1.6°C-4.4°C) prior to loading. Failing to supply concentrate inside the recommended temperature range, especially below 35°F (1.6°C), will cause an out of brix drink (refer to the Brixing
Procedure section for details).
LOADING CONCENTRATE
The Quest Juice Dispenser is designed to use either disposable juice concentrate
containers or the optional Cornelius generic refillable container sold separately.
1. Thoroughly shake thawed concentrate prior to use.
2. Place concentrate containers on the dispensing platform shelf inside the refrigerated cabinet.
3. Engage the concentrate container by pressing it downward into the bottle adapter
opening on the dispensing platform.
NOTE: Be sure to lubricate the o-ring seal on the container nozzle. This will ensure a good seal
and allow the pumps to draw concentrated from the containers more easily. Failure to create a
good seal at this connection may result in weak drinks and/or seepage of concentrate.
4. Prime each pump by closing the cabinet door and press each dispense button until concentrate flows
from the dispense nozzles.
CHANGING CONCENTRATE CONTAINERS:
1. Open the cabinet door and move the valve handle from “Dispense” to “Flush”
2. Close the door. Depress and hold the dispense button until clear water flows from the dispense nozzle.
3. Open the cabinet door and return the handle to “Dispense”.
4. Depress and hold the dispense button for 1-2 seconds. This will relieve water pressure from the concentrate pump system.
5. Load concentrate container (see Loading Concentrate).

Your will also need a flat blade screwdriver to turn a screw if brix adjustments are required.
NOTE: The refractometer shown above, P/N 511004000, is available through your local Cornelius
Distributor.
CHECKING/ADJUSTING THE B RIX SETTING
The following instructions are for use with a refractometer.
1. Dispense approximately 8 oz. (236 ml) of drink and discard. Now draw a second 8 oz. drink.
2. Check drink temperature with a reliable thermometer (target is 35-45°F, or 1.6-7.2°C). Discard
this drink after checking temperature.
NOTE: If drink temperature is not within the target range, refer to the basic troubleshooting section. When setting up the unit with warm concentrate and hot water (90°F) it will take longer to
get the 35-45°F finished drink.
3. Dispense a 12 oz (354.8 ml) drink sample into a clean, dry cup. Thoroughly stir the sample using a
straw. (Adjustments should be made in 1/8 to 1/4 turn increments).
4. Using a straw, transfer a small sample of finished drink to the refractometer lens (refer to operating
instructions supplied with your refractometer). Check the brix reading against the brix chart below.
NOTE: The following brix chart is generic and intended for reference use only. Contact your frozen concentrate supplier for specific brix readings.

the preferred speed. Most concentrates use this setting. Low speed is only used when the water pressure is at the low end of the range (25 PSI or less) and the concentrate is a very thin viscosity such as
apple or cranberry. Low speed cuts the output voltage to 18VDC.
Using a water booster system to increase the flowing pressure to the recommended pressure is a
better solution.
5. To change the brix setting, simply readjust the water flow rate.
Located on each of the valve assemblies inside the refrigerated
compartment are the adjusting screws for the water flow rate (one
per valve).
If the brix reading is too high or low, rotate the appropriate water flow
control according to the diagram below. Repeat steps 1-5 until the brix
setting is achieved.
Lowers Brix by increasing water
Raises Brix by reducing water
IMPORTANT: When making changes to the water flow control, do not rotate more than 1/4 turn
per adjustment. Additionally, prior to taking your next brix reading, “tap” the corresponding dispense button several times prior to drawing a sample. This will clear remnant drink from the dispense nozzle AND help move the flow control to its new setting.
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-programmed 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 portion, then release
the button. Repeat the above procedure for the remaining sizes.
3. After programming all the drink sizes, press and release the “cancel/pour” switch to return
the Portion Control to the operational mode. The blinking REFILL light will go out.
4. If at a future date it is decided to change the portion size of the drinks, the individual sizes
can be adjusted by the above procedure. 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
Cancel/Pour button. Release when the glass is full.

IMPORTANT: DO NOT wash nozzles, static mixers, or mixing chambers in a dish washer. This
will distort the plastic and damage the o-rings. Additionally, do not soak them in sanitizing solution longer than 2 minutes.
WEEKLY
Check concentrate to water brix ratio (refer to the Brixing Procedure in this manual).
Sanitize the Juice Dispenser:
Step 1 - Rinse With Hot Water
1.
Prepare two 2 oz. packets of Stera-Sheen Green Label sanitizing solution (or similar brand) by dissolving each packet in 1 gallon (3.8L) of potable water to insure 200 ppm of available chlorine.
IMPORTANT: Use potable water at 80°F-100°F (26.7°C-37.8°C). Water above this range will breakdown the chlorine count and minimize sanitation.

3.
4.
5.
6.
7.
Remove the juice concentrate containers and place them in separate refrigerated compartment.
“Flush” the system by following the instructions in the Daily Section.
Fill a clean empty concentrate container with one quart of extremely hot tap water, approximately
140°F (60°C) and place into unit. Dispense all of the hot water into a large container. Repeat for the
remaining dispense valves.
Remove the mixing chambers, nozzles, and static mixers. Rinse in hot water to remove excess pulp
and concentrate.
Place the mixing chambers, nozzles, and static mixers in a separate container of sanitizing solution
and agitate vigorously. Allow the parts to soak for two minutes. Rinse thoroughly with fresh tap
water.
Reinstall the static mixer, nozzles, and mixing chambers.

PUMP S PEED SWITCH
The pump speed switch has two settings, low and high. For most dispensing situations high speed will be
the preferred speed. Most concentrates use this setting. Low speed is only used when the water pressure is at the low end of the range (25 PSI or less) and the concentrate is a very thin viscosity such as
apple or cranberry. Low speed cuts the output voltage to 18VDC.
Using a water booster system to increase the flowing pressure to the recommended pressure is a
better solution.
ICE BANK CONTROL
The ice bank control is the only devise used to
control the refrigeration system for both the
cabinet and the water chiller.
Operational Overview
There is no adjustment of any kind to this control. The control will not activate without having
sufficient water in the water bath tank.
(See chapter on installation -water bath filling)
THERE IS A 3 -MINUTE DELAY BUILT INTO EACH CONTROL AS A SAFTEY PRECAUTION.
The default mode is an open circuit. Any break in the continuity i.e. broken wire, and the system reads it
as a no water condition.
Control is powered by line voltage. All connectors are label and keyed for proper installation.
Validating Operation
With box detached from the unit, remove the
ice bank probe connector by gently rocking the
wrench up and down to loosen and pull off to
remove.
As the probe is very low voltage, insert a standard set of pliers into the connector gripping
the middle terminal and allowing the Pliers’
jaws to come in contact with the outside 2.
Wait the 3 minutes and the compressor and
condenser fan should cycle on. Run for 1
minute and remove the pliers.
The compressor will shutdown in 45-60 seconds. If it does not then a sticking relay is a possibility and the
control should be replaced.

TRANSFORMER
This is a dual stage transformer with 2 outputs.
The purpose of the transformer is to step the
line voltage to 26 VAC primary to the electrical
box and the VRB and 24 VAC secondary is to
light the merchandiser.
Current production transformers are equipped
with a thermal overload protection device that
will cut out when high temperature or high
amperage is detected. THE OVERLOAD
RESETS AUTOMATICALLY
Primary wires are Blue
Secondary are Red
WATER INLET SOLENOID
The water inlet solenoid is connected to the
incoming water line and is only activated when
the dispense button is pressed. The water inlet
solenoid prevents backflow and is equipped
with a strainer screen that needs to be
removed and cleaned once a year.
NOTE: THE INLET SOLENOID COIL IS

PROBLEM
Brix Problem
Pump Inoperative
Machine continues to
dispense after dispense button is
released or dispenses without operator input
© 2004, IMI Cornelius Inc.
PROBABLE CAUSE
REMEDY
•
Water supply pressure too low,
less than 20 psi (1.4 bar) flowing
water pressure fluctuates sharply
•
Correct water supply problem to
ensure a constant 50 psi (3.5 bar)
flowing to the dispenser
•
Water flow control binding or
spring is defective
•
Clean and/or replace parts as necessary
•
Improperly thawed concentrate.
Brix changes as the concentrate
temperature changes (concentrate becomes thinner as temperature rises)
•
Concentrate should be 35-40°F
(1.7-4.5°C) prior to loading
•
Pump motor defective
•
28VDC should be present at pump
motor during dispense. If voltage is
present and motor does not start,
replace pump motor
•
No power to transformer or no
28VAC output from transformer
•
Confirm transformer has line voltage
present on primary side. If no
28VAC output from the secondary
replace transformer
•
Defective voltage regulator board
(VRB) located inside front electrical box
•
Confirm board produces 28VDC
present when the dispense button is
pressed (refer to the Electrical Box
Wiring Diagram for VDC output location). Replace VRB if necessary
•
Defective dispense control board
(Push button or portion control)
•
Test and replace if necessary
•
Push button or portion control pad
stuck in on position
•
Disconnect the wire harness from
the rear of the portion control and
close the door. If unit does not dispense on its own the dispense control board is bad (stuck on)
•
Relay on voltage regulator board
(VRB) stuck on.
•
Disconnect the 4-wire harness from
the lower right corner of the VRB. If
the unit continues to dispense on its
own the VRB is defective (relay
stuck on)
