MECHANICAL SERVICE REQUIREMENTS
L
OCATION
The dispenser will tolerate a s/- 1/2
o
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.
E
LECTRICAL
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.

RAINAGE
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.

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.
