1. INSTALLATION
1.1 RECEIVING
Each unit is completely tested under operating conditions and thoroughly inspected before
shipment. At the time of shipment, the carrier accepts the unit and any claim for damage must be
made with the carrier. Upon receiving unit(s) from the delivering carrier, carefully inspect carton for
visible indication of damage. If damage exists, have carrier note same on bill of lading and file a
claim with the carrier.
1
1.2 UNPACKING
A. Remove cup rest by lifting out.
B. Remove splash plate by pulling forward at the bottom. Drip tray can be removed before
removing splash plate.
C. Remove drip tray by lifting out.
D. Remove shipping base. DO NOT LAY UNIT ON ITS SIDE OR BACK. DO NOT USE DRIP
TRAY FRAME FOR A HANDLE.
NOTE
If unit is to be transported, it is advisable to leave unit secured to plywood shipping base.
E. Inspect unit for concealed damage. If damage exists, notify delivering carrier note and file a
claim against the carrier.
1.3 INSTALLATION
The dispenser is designed to sit on a flat, supported surface capable of supporting a minimum
weight of 200 pounds (90.7 kg). It may be either counter or leg mounted. When the dispenser is to
be permanently bolted to the counter top, seal dispenser base to counter top with a silicone sealant
which provides a smooth and easily cleanable bond to the counter.
NOTE
NSF listed units must be sealed to the counter or have four (4) inch legs installed.
W
ARNING
FAILURE TO MAINTAIN PROPER AIR CLEARANCE WILL CAUSE THE COMPRESSOR TO
OVERHEAT AND WILL RESULT IN PREMATURE COMPONENT FAILURE.
Locate dispenser to allow approximately 15 inches (380 mm) of unobstructed space above and six
(6) inches (152 mm) of unobstructed space in back of the unit for proper air circulation and removal
of bonnet. Air is drawn in through the back grill and is exhausted out the top grill.
A. Position dispenser on counter.
B. Remove bonnet from the dispenser.
C. Remove insulation strip from in front of refrigeration deck. Fill tank with water until water comes
out of overflow tube. Replace insulation. Use bottled water where a water problem exists.
1.4 CONNECTING TO ELECTRICAL POWER
W
ARNING
THIS UNIT MUST BE PROPERLY ELECTRICALLY GROUNDED TO AVOID POSSIBLE FATAL
ELECTRICAL SHOCK OR SERIOUS INJURY TO THE OPERATOR. THE POWER CORD IS
PROVIDED WITH A THREE PRONG GROUNDED PLUG. IF A THREE-HOLE GROUNDED
ELECTRICAL OUTLET IS NOT AVAILABLE, USE AN APPROVED METHOD TO GROUND THE
UNIT.
DO NOT USE EXTENSION CORDS WITH THIS UNIT. DO NOT “GANG” TOGETHER WITH
OTHER ELECTRICAL DEVICES ON THE SAME OUTLET.
A. Check the dispenser serial number plate for unit's correct electrical requirements. Do not plug
into electrical outlet unless unit electrical configuration, located on serial plate, agrees with local
available power supply.
B. Route the power supply cord to a grounded electrical outlet of the proper voltage and amperage
rating, and plug in the unit. This will turn on the refrigeration system and allow it to start cooling
and allow ice bank to form while completing installation. Approximately four (4) hours are
required to form a full ice bank.
NOTE
Units equipped with an electronic ice bank control contain a five (5) minute delay. Compressor
and fan motor will not begin running until five (5) minutes after the unit is energized.
1.5 CONNECTING SUPPLY LINES TO SOURCES
A. Connect free end of plain water lines to water supply [must be 35 PSI (2.4 BAR) or more].
2
B. Mark both ends of product and water lines and route to dispenser. Flush lines to be sure each
is clean. Failure to do so may result in clogging of valve(s), resulting in improper operation.
Connect lines to dispenser and secure using Oetiker clamps.
C. Route drain tube to dispenser.
D. Connect drain tube to drip tray and install on dispenser.
E. Turn on water supply.
F. Open all dispenser valves until air is bled from system.
G. Actuate valve until a smooth flow of water is obtained.
H. Check for leaks.
I. Connect free ends of product lines to proper tanks or bag-in-box.
J. Check for syrup leaks.
K. Adust the water flow.
L. Install splash plate on dispenser.
M. Install cup rest on dispenser.
N. Replace bonnet on dispenser.
2. SCHEDULED MAINTENANCE
2.1 DAILY
A. Remove the nozzle and diffuser from each valve and rinse well in warm water. Do NOT use
soap or detergent. This will cause foaming and off taste in finished product.
B. Remove the cup rest and wash in warm soapy water.
C. Pour warm soapy water into the drip tray and wipe with a clean cloth.
D. With a clean cloth and warm water, wipe off all of the unit's exterior surfaces. DO NOT USE
ABRASIVE SOAPS OR STRONG DETERGENTS.
E. Replace the cup rest, valve diffusers, and valve nozzles.
2.2 WEEKLY
A. Taste each product for off tastes and/or brix changes.
B. Remove the bonnet and check the level of water in the water bath. Replenish as required, and
replace the bonnet.
2.3 MONTHLY
A. Unplug the dispenser from power source.
B. Remove the bonnet and clean the dirt from the condenser using a soft brush.
C. Replace the bonnet and plug in the unit.
2.4 EVERY SIX MONTHS
A. Clean and sanitize the unit using the appropriate procedures outlined in Section 3 of this
manual.
2.5 YEARLY
A Clean water bath interior, including evaporator coils and refrigeration components.
B. Clean the entire exterior of the unit.
C. Sanitize syrup lines.
3. DISPENSER CLEANING AND SANITIZING
3.1 AMBIENT PROCESS
A. The ambient process is the most common method for cleaning and sanitizing dispenser
equipment. The detergent should be caustic-based and the sanitizer should be low pH (7.0)
chloride solution.
B. Disconnect syrup containers and remove product from tubing by purging with carbon dioxide.
C. Rinse the lines and fittings with clean, room temperature water to remove all traces of residual
product.
D. Fill lines with a caustic-based (low-sudsing, non-perfumed, and easily rinsed) detergent solution.
The solution should be prepared in accordance with the manufacturer’s recommendations, but
should be at least two (2) percent sodium hydroxide. Make sure the lines are completely filled
and allow to stand for at least ten (10) minutes.
E. Flush the detergent solution from the lines with clean water. Continue rinsing until testing with
3
phenolpthalein shows that the rinse water is free of residual detergent.
F. Fill the lines with a low pH (7.0) chlorine solution containing at least 50 parts per million (PPM)
(50 mg/L) available chlorine. Make sure that lines are completely filled and allow to stand for
ten (10) minutes.
G. Reconnect syrup containers and ready Unit for operation.
W
ARNING
REMOVE SANITIZING SOLUTION FROM DISPENSER AS INSTRUCTED. RESIDUAL
SANITIZING SOLUTION LEFT IN SYSTEM COULD CREATE HEALTH HAZARD.
H. Draw drinks to refill lines and flush the chlorine 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.
I. Taste the beverage to verify that there is no off taste.
3.2 VALVES
A. Valves may be cleaned and sanitized in the same manner
1. Remove cover and disconnect power so not to activate the valve while cleaning. Remove
nozzle and diffuser. Wash these parts in cleaning solution, then immerse them in a bath of
sanitizing solution for 15 minutes.
2. Visually inspect around nozzle area for syrup residue. This area may be cleaned with warm
water and cloth or with the nozzle brush supplied. Wipe off dispensing lever.
3. Wearing sanitary gloves, remove, drain and air dry the nozzle and diffuser.
4. Wearing sanitary gloves, replace diffuser and twist nozzle into place.
5. Draw drinks to flush the chlorine solution from the valves.
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.
6. Taste the beverage to verify that there is no off taste.
7. Connect power and replace cover. Valve is ready for operation.
