APPLICATIONS
This appliance is intended to be used in household and similar applications such as the following:
• Staff kitchen areas in shops, offices and other working environments.
• Farm houses and by clients in hotels, motels and other residential type environments
• Bed and breakfast type environments
• Catering and similar non-retail applications
PLUMBING REQUIREMENTS
This dispenser must be connected to a COLD WATER system with operating pressure between 30psi minimum
and 60 psi maximum (206.8 kilopscals and 413.7 kilopscals). This water source must be capable of producing a
minimum flow rate of 3 fluid ounces (88.7 milliliters) per second. A shut off valve should be installed in the line
before the dispenser. Install a regulator in the line when pressure is greater than 100 psi (690 kPa) to reduce it to
50 psi (345 kPa). The regulator is also necessary if the water source has pressure fluxuations. The main water inlet
is a 3/8” (9.52 mm) MFL connection (Figure 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.
MINIMUM AIRFLOW CLEARANCE
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.
The Dispenser needs to be placed using 4inch legs that are included.

FILLING THE ICE BATH
The ice bath holds approximately 3.5 gallons (13.4 liters) of water. The fill tube is located behind the front splash
plate and capped with a 0.5” plug.
1. Remove the 0.5” plug and attach the tube to any one of the dispense nozzles.
2. Open the door and verify that the flush/dispense lever is in the dispense mode. (see Figure 6) Ice
bath must always be filled in the dispense mode.
NOTE: Non flush units does not have a flush/dispense lever hence for filling water bath on non
flush units please remove the concentrate Storage bottles first and then attach the tube to
any one of the dispense nozzles and Close the door, press and hold the dispense button
(push) until the tank is filled and water trickles from the overflow

CONNECTING THE WATER SUPPLY
The Quest Elite 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.
Water Inlet
with Supply Tubing
Connected
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 8. Water Supply Connection on Rear of Unit
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.
ELECTRICAL REQUIREMENTS
A minimum of 15 amps electrical service is needed for 120VAC power supply. A minimum of 10 amps electrical
service is needed for 230VAC power supply.

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 procedure described in .
Table 1.
Step Action
1
Simultaneously, press and hold Small and Extra Large buttons on
the Portion Control Module until the Refill light starts blinking.
Release the buttons. The blinking Refill light indicates the program-
ming mode is active. See . Control Panel.
2
Place a 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 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 goes off.
4
In the future, to change the portion size of the drinks, the individual
sizes can be adjusted by performing Step 2. It is not necessary to
reprogram every size. Additionally, the portion control has full mem-
ory retention in case of a power failure.
Figure 10. Control Panel
STOP BUTTON
To pour a drink without using a pre-programmed portion control size, simply push and hold the Stop button.
