and strainer

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 tub-

ing. 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.

When changing concentrate, be sure to check the concentrate container O-ring for damage. It should

be clean and wet with concentrate or a food grade lubricant.

•

Shake or stir pulp based concentrates.

When changing flavors, be sure to flush the system and reset the pump.

Nozzles should be cleaned daily. Remove the nozzles and wash in warm soap solution. Rinse with

clean water, lubricate the O-ring, and replace nozzle.

•

Flushing daily and sanitizing weekly is recommended.

SETTING THE BRIX

•

A refractometer must be used to measure the post-mix brix.

KEY THINGS TO KNOW / DO

•

Work Safely! Always unplug/disconnect the power to the dispenser before servicing, and get help lift-

ing 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 BATH

The fill tube is located behind the splash panel. Use the water supply line to fill the ice bath before con-

necting 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 fin-

ished filling the ice bath. Lock it in place with its holder.

overflow

IMPORTANT: Fill the water bath slowly until it runs out

the overflow. Failure to do so can cause back pres-

sure 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 SYSTEM

Dispense/

Flush Lever

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 dis-

pense 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) compart-

ment 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°F-

40°F (1.6°C-4.4°C) prior to loading. Failing to supply concentrate inside the recommended tem-

perature 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 refriger-

ated 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 noz-

zle.

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 con-

centrate pump system.

5. Load concentrate container (see Loading Concentrate).

BRIXING PROCEDURE

NOTE: If concentrate is not properly thawed, it will adversely affect the amount of concentrate

dispensed. Thawed product should be between 35°F/1.6°C to 40°F/4.4°C.

NOTE: You can not dispense drinks with the door open.

SUPPLIES

•

1-Small 12 oz. cup (354.8 ml)

•

1-Large 21 oz. cup (621.1 ml)

1-Straw

Paper Towel

1-Thermometer

1-Refractometer

Concentrate Separator (720601323)

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 BRIX 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 sec-

tion. 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 fro-

zen concentrate supplier for specific brix readings.

Pump Speed 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 pres-

sure 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 increasingwater

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 dis-

pense button several times prior to drawing a sample. This will clear remnant drink from the dis-

pense nozzle AND help move the flow control to its new setting.

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.

PLANNED MAINTENANCE SCHEDULE

DAILY

Flush System:

Move Dispense/Flush levers located on the platform assembly in

the refrigerated cabinet to the “Flush” position. Place an empty

cup on the drip tray below each dispense nozzle.

Close the door and depress each dispense button for 2-3 sec-

onds or until clear water flows from each dispense nozzle.

Return the Dispense/Flush levers to the “Dispense” position.

Press each dispense button for 1-2 seconds to release the water

pressure present in the concentrate pump system.

Clean Splash Zones & Dispense Nozzles:

On a daily basis, clean the external cabinet and

splash areas using a clean damp cloth. Remove

and wash the cup rest and drip tray using a mild

dish soap.

Remove the dispense nozzles and static mixers

by rotating each 90° and pulling down. Remove

the mixing chambers by pulling straight forward.

Wash using a mild dish soap.

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 solu-

tion 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

Prepare two 2 oz. packets of Stera-Sheen Green Label sanitizing solution (or similar brand) by dis-

solving 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 break-

down the chlorine count and minimize sanitation.

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.

the lines for 5 minutes.

4. After 5 minutes, dispense the remaining sanitizing solution.

Step 3 - Prepare Dispenser for Use

1. Replace sanitizing solution container with a concentrate container and close the door.

2. Press and hold the dispense button until juice appears from the nozzle. Next dispense and discard

at least two 8 oz. (236.6ML) cups of juice in order to prime the system and prepare it for operation.

PUMP SPEED 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 pres-

sure 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 con-

trol. 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 stan-

dard 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.

DOOR SWITCH - 72 B SERIAL NUMBER

The door switch on the 72B serial number units

is a combination of a door latch and switch. The

primary function of the door switch is to inter-
