INSTALLATION INSTRUCTIONS
RECEIVING
Each unit is completely tested and inspected before shipment. At time of shipment, the carrier accepts the unit and
any claim for damage must be made with the carrier.
Upon receiving from the carrier, please, 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 top insert and shipping bag.
• Open upper cabinet door and remove installation kit.
• Remove bolts securing unit to pallet.
• Lift unit off of pallet.
• Open the package, take the legs and secure them to the bottom of the unit.
NOTE: Do not lay the unit on sides or on the back. This may cause vital oils to drain from the compressor
resulting in damage during start-up and consequently voiding the warranty.
Tilt the unit only when securing legs.If the unit is to be transported from the place where it was unpacked, do not
remove the unit from the pallet. Transport it on the pallet to the installation site.
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,
4” (10.16cm) on sides and open to the front is required. The space between bottom of the unit and counter cannot be
obstructed.
IMPORTANT: Condenser air is drawn from the rear and discharged out the top. Failure to maintain
clearance space will reduce capacity of the unit and cause premature compressor failure.
Recommended Clearance
12” (30.48 cm) on top and 4” (10.16 cm) required in back for air circulation and 4”(10.16cm) at the sides of the unit.

INSTALLATION
Electrical Connection
6 ft. long (1.83 m) power cord with 3-prong plug attached to dispenser. Export models are shipped with a European
plug. The plug is accessible after installation
CAUTION:
!
Only trained and certified electrical technicians should replace the power cord or the unit should be returned to an
Authorized Service Center for power cord replacement.” The replacement cord must meet all requirements of the
original equipment manufacturer.
Failure to comply could result in serious injury, death or damage to the equipment.
Power Supply
10 amps at 230 volts dedicated power supply.
Water Booster System
Install the Water Booster system on the dedicated Quest Elite Water supply line.Preferred location is in the Back
Room Area and close to water- gas and/or electricity supply.

Booster Installation Notes:
Refer to the OEM manufacturers installation instructions
Boosters and accumulator tanks should be fed with AMBIENT water only. To avoid condensation and premature
equipment failure, do not install the water booster assembly in the refrigerated water supply circuit.
To prevent pressure drops in the water supply line, use 3/8” / 9.5 mm ID supply lines only. Limit the amount of flow
restrictions s.a. shut-off valves, manifolds and/or fitting.
Water Connection
3/8 in. (0.95 cm) SAE male flare fitting on dispenser (see figure 5).
Figure 5.
The Quest Elite QLT 2000 series Juice Dispensing machine is designed to dispense juice at a high flow rate. It is very
important that the incoming water line is dedicated for the unit, or at least does not have other machines connected
which could cause a water surge, i.e., a dish washing or coffee machine.
Notes:
The unit should be fed by an insulated chilled water line from the soft drink beverage system. To achieve both optimal
brix control and sanitation, assure that the incoming water pressure is at least 60 psi (4.2 bar) dynamic coming from
the water booster system.
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.
A. 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 P/N 311304000 is included with the
installation kit).
Figure 6.
B. When securing flare nut, use backup wrench on 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.

Flushing System
To properly prime the unit with water and remove air pockets in the
system, open the cabinet door and make sure the protective dust cap
is in place on top of the mixing chamber. Close the door and push the
“STOP” Button for a few seconds. Repeat until a steady flow of water is
observed.
1. Remove the Splash Panel (2 screws next to drip tray brack-
ets) .
2. Release filling tube.
3. Remove the red cap.
4. Install the filling tube onto the RH dispense nozzle.
5. Assure that the RH mixing chamber is capped off to prevent
the cabinet flooding with water.
Filling the Water Bath
6. Close the cabinet door, and push the dispenser button – dis-
pense water only
7. Fill the water bath until water evacuates from the overflow
8. Evacuate approx. ½ liter of water. This Eliminates dripping
from the overflow when building the ice bank
9. Install the red cap onto the filling tube, and replace into the
bracket
10. Allow the cabinet to reach 4°C prior to load any concentrate
into the cabinet. This takes approx. 1 hour
NOTE: Water splashing may occur during this purge cycle.

Programming the Portion Control
1. Simultaneously, press and hold “small” and “extra large” push button switches on the Portion Control Mod-
ule until the “REFILL” light in the corner of the module starts blinking. Release the switches. The blinking
light indicates the programming mode is active.
2. Place the cup under the white mixing valve 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 “STOP BUTTON” to return the Portion Control
to the operational mode. The blinking REFILL light will go out.
REFILL
Figure 10.
If in future 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 re-program every size. Additionally the portion control has a full memory retention in
case of a power failure.
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.

4. Connect the nipple of the mixing chamber onto the silicone tube
5. Hold the mixing chamber sideways when sliding the nipple onto the sili-
cone tube
6. Slide the Mixing chamber in position and push firmly into the pump deck.
Make sure that the lid of the mixing chamber is properly installed and screwed on
tight.
Failure doing so will cause the entire chamber to flood with drinks and
eliminating the anti-splattering effect.
