5. INSTALLING
A. 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.
B. UNPACKING
1. Remove plywood shipping base from unit by moving unit so that one side is off the countertop
or table, allowing access to screws on the bottom of shipping base.
2. Assemble legs by lifting unit. DO NOT LAY UNIT ON ITS SIDE OR BACK.
NOTE:
If unit is transported, it is advisable to leave unit secured to plywood shipping base.
2
3. Inspect unit for concealed damage. If damage exists, notify delivering carrier note and file a
claim against the carrier.
C. INSTALLATION
The unit 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 unit is to be
permanently bolted to the countertop, seal dispenser base to countertop with a silicone sealant,
which provides a smooth and easily cleanable bond to the countertop.
NOTE:
NSF listed units must be sealed to the countertop or have four (4) inch legs installed.
WARNING
FAILURE TO MAINTAIN PROPER AIR CLEARANCE WILL CAUSE THE COMPRESSOR TO
OVERHEAT AND WILL RESULT IN PREMATURE COMPONENT FAILURE.
1. Position unit on countertop.
IMPORTANT
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 BACK GRILL AND IS EXHAUSTED OUT THE TOP GRILL.
2. Remove bonnet from the dispenser.
NOTE:
The water bath compartment must be filled with water before connecting to electrical power.
Otherwise, the compressor deck may not operate properly.
3. 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 water problem exists.
D. CONNECTING TO ELECTRICAL POWER
WARNING
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.
1. Check the unit serial number plate for correct electrical requirements. Do not plug into
electrical outlet unless unit electrical configuration, located on serial plate, agrees with local
3
available power supply.
2. 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 three (3)
hours are required to form a full ice bank.
NOTE:
Units equipped with an electronic ice bank control contain a ten (10) second delay.
Compressor and fan motor will not begin running until ten (10) seconds after the unit is energized is
plugged into an electrical outlet.
E. CONNECTING SUPPLY LINES TO SOURCES
1. Connect free end of plain water lines to water supply [must be 35 PSI (2.4 BAR) or more].
2. 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.
3. Route drain tube from dispenser to drain.
4. Turn on water supply.
5. Check for leaks.
6. SCHEDULED MAINTENANCE
A. WEEKLY
1. Remove the bonnet and check the level of water in the water bath. Replenish as required, and
replace the bonnet.
B. MONTHLY
1. Unplug the dispenser from the power source.
2. Remove the bonnet and clean the dirt from the condenser using a soft brush.
3. Replace the bonnet and plug in the unit.
C. EVERY SIX MONTHS
1. Clean and sanitize the unit using the appropriate procedures outlined in Section 7 of this
manual.
D. YEARLY
1. Clean water bath interior, including evaporator coils and refrigeration components.
2. Clean the entire exterior of the unit
7. DISPENSER CLEANING AND SANITIZING
A. AMBIENT PROCESS
1. 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.
2. Disconnect syrup containers and remove product from tubing by purging with carbon dioxide.
3. Rinse the lines and fittings with clean, room temperature water to remove all traces of residual product.
4. Fill lines with a caustic-based (low-subsiding, 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.
5. Flush the detergent solution from the lines with clean water. Continue rising until testing with
phenolphthalein shows that the rinse water is free of residual detergent.
6. Fill the lines with a low pH (7.0) chlorine solution containing at least 50 parts per million (PPM)
4
(50 mg/L) available chlorine. Make sure that lines are completely filled and allow to stand for
ten (10) minutes.
7. Reconnect syrup containers and ready unit for operation.
WARNING
REMOVE SANITIZING SOLUTION FROM DISPENSER AS INSTRUCTED.
RESIDUAL SANITIZING SOLUTION LEFT IN SYSTEM COULD CREATE HEALTH HAZARD.
8. 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.
9. Taste the beverage to verify that there is no off taste.
