IMPORTANT INFORMATION AND SAFETY NOTES. PLEASE READ BEFORE
INSTALLING DISPENSER.
• Always transport equipment in an upright position and never drag over rough floors or down steps.
• A trained person, who is qualified to make connections to water, electrical and/or compressed gas
supplies must only carry out installation and maintenance. Local by-laws/regulations must be
followed.
• Switch off and unplug electrical power to unit during maintenance operations. Do not attempt to
remove any protective covers.
• Locate equipment on a firm, level surface and protect from physical damage. Mounting surface must
be able to support 500 lbs. (227kg) weight. Never allow air vents/louvers to become blocked and do
not place any non-specified items on top. Regularly clean condensers and louvers with a soft brush or
vacuum.
• This dispenser is for indoor use only. Do not expose equipment to extremes of temperature, water
spillage, spray, steam, or high humidity or clean with water jet into dispenser components because
this could cause damage to electrical components and shock to personnel. Do not place or store
objects on top of unit.
• This dispenser must be connected to correctly rated electrical power outlet, preferably protected by a
safety cutout and is easily accessible for isolation of the equipment. The equipment must be earth
grounded.
• Use and ELCB (earth leakage circuit breaker)/GFCI (ground fault interrupt) for electrical power
protection.
• Use an HVAC circuit breaker to the power outlet circuit supplying the dispenser.
• Each module or accessory requires a 120 VAC 15 Amp 60 HZ grounded outlet. If 230 VAC 50/
60 HZ, use a minimum of 10 Amp outlet for each module or accessory.
• Ambient temperature must not exceed 90oF (32.3oC) on units with merchandisers.
WATER SYSTEM
• Insufficient water supply to carbonator will cause pump damage.
WARNING: If the installation is idle and exposed to freezing temperatures, disconnect water
supply lines and blow out all water from pump, carbonator tank, and dispensing system.
WARNING: UNDETECTED CO2 LEAKS MAY CAUSE HARM OR DEATH DUE TO ASPHYXIATION.
CO2 tank must be located next to a solid wall and chained to the wall. CO2 cylinders must be
secured in a vertical position and only connected to dispensing equipment via a suitable
pressure regulator. Check connections for leaks.
WARNING: DO NOT lift dispenser modules by valve housing assemblies. Lifting by the valve
housing assemblies will cause damage to the housing.
WARNING: System must be sanitized in accordance with the procedures found in this manual
under the cleaning and maintenance section.
WARNING: Before attempting to remove the refrigeration deck, disconnect all electrical power.
Melt the ice bank and thoroughly drain the water bath. See additional notes in Water Bath
Cleaning Section in the manual.
The dispenser will tolerate a surface +/- 1/2o or +/- 1/8” per foot or +/- 10.4mm per meter maximum slope
without affecting refrigeration capacity or cause water spillage from water bath.
Do not install dispenser next to any heat producing equipment such as furnaces, ovens, deep-fat fryers.
Never store items on top of dispenser which will restrict the air flow through the air-cooled condenser coil.
Clearance: The space above the dispenser must have a minimum of 16 inches (406mm). Of clearance
to allow for the removal of the top cover and refrigeration chassis and to provide adequate ventilation.
There should be at least 1 inch (25.4mm) of clearance on each side and to the rear of the dispenser for
servicing and ventilation.
ELECTRICAL
The electrical power supply should conform with that printed on dispenser name plate.
All other electrical connections are to comply with local codes.
A wiring diagram can be found in Section 7.0 of this instruction manual.
A separate electrical circuit with a minimum rating equal to the electrical ratings shown on the dispenser
nameplate (amperage and voltage) is recommended for satisfactory operation.
Installation and Service Manual
WATER SUPPLY & DRAINAGE
A water supply having a 1/2” O.D. (12.7mm) copper water tube, minimum is required with a minimum 20
PSIG (1.4 bar) line pressure.
A shut-off valve within three feet (1 meter) of the unit is recommended.
A suitable water filter is recommended to ensure top quality drinks.
A water pressure regulator or reducing valve should be installed in line to the main water supply and set
at 30 to 40 psi (2.1 to 2.8 bar). By limiting the incoming water pressure, a 15 psi (1.05 bar) pressure
differential (water pressure versus higher carbonator CO2 gas pressure) will ensure that flooding of the
carbonator tank does not occur.
Teflon pipe tape should be used (as required) on any fittings used in the water system.
Any contaminants such as dirt, cutting oil, pipe dope left in the system may affect the quality of the
finished drink. Therefore, flush water lines prior to start up.
CARBON DIOXIDE (CO2) GAS SUPPLYTO CARBONATOR
For the product tank supply line use a CO2 regulator capable of 0 psig to 100 psig (6.8 bar) normal
working pressure. Recommended setting 75 psi (5.17 bar).
A minimum CO2 gas supply pressure 15 psi (1.05 bar) greater than the incoming water pressure will
ensure that flooding of the carbonator tank will not occur.
Syrup containers, sold as an accessory, are stainless steel with a capacity of five gallons (18.9 liters).
They are equipped with a CO2 gas quick disconnect fitting and syrup quick disconnect fitting.
The dispenser’s syrup outlets are 1/4” (6.4mm) barb fittings, and are located at the front wall, mid-height,
of the dispenser.
Each syrup inlet in labeled with the valve number that it services.
If the “syrup in” lines need replacement or extension, a .265 I.D. (6.7 mm I.D.) polytube is recommended.
Avoid using soft or easily collapsible tubing on the “syrup in” lines.
Only stainless steel or plastic, barb or compression type fittings should be used on any syrup or soda
water connections.
Optional bag-in-box system is also suitable for use with this beverage cooler.
