Functions of the LEDs are:
• Red and Green OFF = no power to the dispenser
• Green ON = line voltage is within acceptable range
11. Connecting the Drain
A. Remove the drip tray from the dispenser and drill out the stem with a 7/16" (11 mm) drill bit.
B. Route one end of the 5/8" (15.8 mm) ID hose through the hole in the back of the dispenser marked "drain"
and up to the drip tray fitting located on the dispenser under the drip tray.
C. Attach the hose to the drip tray fitting on the dispenser.
D. Connect the other end of the hose to a suitable drain source, ensuring compliance with all federal, state
and local codes.
E. Slide the drip tray back into place.
12. Purging Air from the Water Coil
A. Prior to initial use, purge all air from the valves by pushing the dispensing switch repeatedly. Continue until
a steady flow of water is observed.
B. Repeat for the remaining valves.
NOTE: Splashing may occur during the purge cycle.
13. Programming the Portion Control
A. If the dispenser comes equipped with the optional Portion Control feature, 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 the "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 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.
B. If in future it is decided to change the portion size of the drinks, the individual sizes can be adjusted follow-
ing 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.
C. To pour a drink without using a pre–programmed Portion Control size, simply push and hold the "cancel/
pour" button and release when the cup is full.
14. Connecting the Concentrate & Priming the Pumps
A. Connect the 3/8" barb fittings to the BIB supply line.
NOTE: DO NOT cut any of the lines coming from the rear of the dispenser. The excess slack is
needed to be able to slide the pump platform out of the front of the base for maintenance access.
B. Route the concentrate supply lines to the BIB location and attach the supplied plastic BIB connector to the
end of each line with the clamps provided.
C. Turn off the water supply and connect the concentrate lines to their respective BIB.
D. Depress and hold each start button until concentrate is observed flowing from the nozzle.
E. Turn on the water supply.
