Unit installation

312022000 10
Locate the Cooling Unit so the following requirements are satisfied.
1. Allow the shortest possible insulated python route from the Cooling Unit to the Dispensing Station location.
2. Cooling Unit Requiring Connection to a Remote Rooftop Condenser Coil and Fan Assembly.
Allow the shortest possible refrigeration lines (not to exceed 50-feet in length) route from the Remote
Condenser Coil and Fan Assembly to the Cooling Unit.
3. REFER TO COOLING UNIT NAMEPLATE FOR THE REQUIRED POWER CIRCUIT OPERATING
VOLTAGE, HERTZ, AND THE MINIMUM CIRCUIT AMPACITY OF THE COOLING UNIT.
The power circuit for the Cooling Unit must be wired through a 40-amp (minimum) rated disconnect switch
(not provided) and the power circuit must be fused as indicated on the Unit nameplate. The power circuit
may also be wired through an equivalent HACR type circuit breaker rather then through a disconnect
switch. THE POWER CIRCUIT MUST BE MADE UP OF COPPER CONDUCTORS AND ALL WIRING
MUST CONFORM TO NATIONAL AND LOCAL ELECTRICAL CODES.
4. The Cooling Unit must be located close to a plain water source supply line with requirements as specified
under CONNECTING CITY PLAIN WATER SOURCE LINE TO THE COOLING UNIT in this section of the
manual.
5. Water-Cooled Cooling Unit.
The water-cooled Cooling Unit refrigeration system requires that a 1/2-inch I.D. (minimum) City plain water
source line with a minimum pressure of 12-psi be available to connect to the Cooling Unit Refrigeration
Cooling Coil Assembly.
6. The Cooling Unit must be close to a permanent drain to route the Cooling Unit water tank drain and
overflow hoses, and the Refrigeration Cooling Coil Assembly water dump line if a Water-Cooled Cooling
Unit.
7. Allow sufficient space around the Cooling Unit for proper air circulation (18-inches on sides and back, front
side open to the room, and top open to the ceiling.
REMOTE ROOFTOP CONDENSER COIL AND FAN ASS’Y
NOTE: The Remote Condenser Coil and Fan Assembly (P/N 4000) is a 208/230 VAC, 50/60 HZ Unit that
may be used with either Cooling Unit (P/N 4004, a 60 HZ Unit) or (P/N 4005, a 50 HZ Unit) which requires
connection to a Remote Condenser Coil and Fan Assembly.
The Cooling Unit refrigeration systems of Cooling Units (P/N 4004) and (P/N 4005) must be connected to a
Remote Condenser Coil and Fan Assembly (P/N 4000) that is authorized by IMI Cornelius Inc. Use of any other
Remote Condenser Coil and Fan Assembly must be authorized by IMI Cornelius Inc. Use of an unauthorized
Remote Condenser Coil and Fan Assembly will automatically void the Cooling Units factory warranty.
An extreme warm climate installation may require extra caution in the Remote Condenser Coil and Fan
Assembly location. Avoid hot sunny locations and seek a shaded area if possible. The use of a structure to
shade the Unit from direct sun exposure and/or a platform extending the Unit an additional 18-inches above the
rooftop is highly recommended and will improve performance. Ample space must be provided on all sides and
above the Unit for proper air circulation through the Unit and also access for service and maintenance. DO NOT
BLOCK AIR CIRCULATION THROUGH THE UNIT.
INSTALLATION
PLACING COOLING UNIT IN LOCATION
The Cooling Unit must be installed meeting requirements of SELECTING LOCATION as follows:
NOTE: The Cooling Unit inlet and outlet lines, power cables, and the Remote Condenser Coil and Fan
Assembly refrigeration lines (if applicable) must be long enough when connected to the Cooling Unit
to allow pulling the Unit out approximately 36-inches from the operating location for service and
maintenance. When Cooling Unit is in the operating location, the excess inlet and outlet lines, power
cables, and the refrigeration lines may be coiled up behind the Cooling Unit.
