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.
2.
Thoroughly shake concentrate prior to use.
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.
2.
3.
4.
5.
Open the cabinet door and move the valve handle from “Dispense” to “Flush”
Close the door. Depress and hold the dispense button until clear water flows from the dispense nozzle.
Open the cabinet door and return the handle to “Dispense”.
Depress and hold the dispense button for 1-2 seconds. This will relieve water pressure from the
concentrate pump system.
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.
SUPPLIES
•
1-Small 12 oz. cup (354.8 ml)
•
1-Large 21 oz. cup (621.1 ml)
•
1-Straw
•
Paper Toweling
•
1-Thermometer
•
1-Refractometer
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.
2.
Dispense approximately 8 oz. (236 ml) of drink and discard. Now draw a second 8 oz. drink.
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.
3.
Dispense a 12 oz (354.8 ml) drink sample into a clean, dry cup. Thoroughly stir the sample using a
straw.
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.

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.

PLANNED MAINTENANCE SCHEDULE
DAILY
Flush System:
1.
2.
3.
4.
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 seconds 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:
1.
2.
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 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.
2.
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.

Step 2 - Sanitize Pump System
1. Fill a clean concentrate container with 2 quarts (1.9L) of fresh sanitizing solution.
2. Place handles in the “dispense” position and close the door.
3. Press and hold the dispense button for 90 seconds then stop. Allow sanitizing solution to remain in
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.

Loosen and remove the four screws from the pump body (see fig 3).
Remove the rear pump body half only to reveal the pump tube and
rollers.
Remove the old pump tube from the pump body. If the roller assembly comes out with the tubing, place it back into the pump housing
being sure to align the roller assembly shaft keyway to the motor
shaft so that the two interlock.
Firmly press the new hose into the pump body around the
roller assembly, being sure to keep the protruding ends even
with each other.
Once the tubing is in place, hold the tubing with one hand, capture the lower part of the tubing with the outer housing, then
proceed to capture the shaft of the roller assembly and push
the rear pump housing into place. Make sure to capture the
tubing within the body and not pinch it between the halves. Do
not use any tool other than your finger tips to manipulate the
Fig. 2
tubing into the housing or you may damage the tube.
