6.
Replace check valve in sanitizing container.
7.
Activate “PURGE BUTTON” for two (2) minutes ensuring concentrate lines are full of
solution. Let solution stand for five (5) minutes without dispensing.
8.
For each valve, perform a second two (2) minute dispense and let stand for an additional
five (5) minutes.
9.
Activate “PURGE BUTTON” until the sanitizing solution empties from the sanitizing
container.
10. Remove check valve from sanitizing container, remove sanitizing container, and pour out
any sanitizing solution that remains in the container.
11. Repeat for each valve.
12. Reinstall Minute Paks
®
, and connect check valves in containers. Replace nozzles (see
Figure 17)
13. Using the “PURGE BUTTON”, run the pump until only concentrate is dispensed, to remove
traces of sanitizing solution from the dispenser.
NOTE
Please note that a fresh water rinse cannot follow sanitization of equipment. Purge only
with the end use product.
This is an NSF requirement.
14. Remove drip tray and cup rest. Wash thoroughly with warm, soapy water using a mild
detergent. Rinse thoroughly with clean, warm water.
15. Wipe the dispenser with a clean damp cloth, taking care to remove all product residue.
16. Replace drip tray, and cup rest.
17. Return key switch to “ON” position
18. Pour approximately two (2) ounces of finished drink product to fill nozzle.

OPERATING PRINCIPLES
3.1
WATER SYSTEM
Inlet water is plumbed through a 1/4 turn ball valve, in the front of the dispenser, to a stainless steel
tube (imbedded in the insulated tank assembly) where it connects to the copper Water Coil on the
left side of the ice bath tank. The water is chilled to below 40
o
F and fed through a Vacuum Breaker
to a distribution manifold. The manifold has four outlets that extend into the interior of the of the
refrigerated compartment. Each outlet connects to a flow meter/solenoid valve which operates the
water flow and measures the amount of water that was dispensed.
3.2
CONCENTRATE DELIVERY SYSTEM
When the dispensing valve is activated, concentrate is drawn from the bottom of the concentrate
container, up the integral dip tube and through the check valve and concentrate tube, to the inlet of
the concentrate pump.
It is metered by volume and pumped into the spout where it mixes with the water. The temperature
of the concentrate does not effect the °Brix as long as it is above 32°F (0°C). The volume output of
the concentrate pump is controlled electronically and can be adjusted to change the °Brix.
3.3
REFRIGERATION SYSTEM
The copper tube evaporator mounted to the compressor deck and located in the water bath
compartment of the insulated tank assembly, forms a ring of ice that weighs approximately
21 pounds. Additional water in the compartment is continuously circulated in the compartment by
the agitator motor to maintain a constant 32
o
F bath temperature. The copper water coil is
mounted to the dispenser and is located directly below the ice bank.
The insulated tank assembly is substantially fabricated out of aluminum plate. Heat is removed from
the concentrate compartment through conduction to the ice bath. Cool air is circulated in the
container compartment by a small fan mounted to the back plate of the container compartment.
When product is dispensed, water is drawn through the water coil and chilled. As ice is depleted,
the ice bank control senses that the ice is melting and turns the compressor and condenser fan on.
When the ice bank is rebuilt, the ice bank control turns the compressor and condenser fan motor
off. The compressor will periodically run to maintain the ice bank even though no drinks were
dispensed. If power to the unit was disrupted while the compressor was running, the compressor
