WARNING: The Cooling Unit must be electrically grounded to avoid possible fatal electrical
shock or serious injury to the operator. A green ground wire is provided inside electrical
box to connect power circuit ground wire which electrically grounds the Cooling Unit.
2. 60HZ Cooling Unit
Connect 208/230VAC Single Phase 60Hz electrical power circuit with a 40-amp minimum rated disconnect
switch (not provided) fused at 40-amps (maximum) or circuit connected through an equivalent HACR circuit
breaker to electrical wires inside electrical handy box on back of cooling unit. DO NOT CONNECT
ELECTRICAL POWER TO COOLING UNIT AT THIS TIME.
COOLING UNIT MUST BE PROPERLY GROUNDED, POWER CIRCUIT MUST BE MADE UP OF
COPPER CONDUCTORS, AND ALL WIRING MUST CONFORM TO NATIONAL AND LOCAL
ELECTRICAL CODES.
50HZ Cooling Unit
Connect 208/230VAC Single Phase 50Hz electrical power circuit with a 40-amp minimum rated disconnect
switch (not provided) fused at 40-amps (maximum) or circuit connected through an equivalent HACR circuit
breaker to electrical wires inside electrical handy box on back of cooling unit. DO NOT CONNECT
ELECTRICAL POWER TO COOLING UNIT AT THIS TIME.
COOLING UNIT MUST BE PROPERLY GROUNDED, POWER CIRCUIT MUST BE MADE UP OF COPPER
CONDUCTORS, AND WIRING MUST CONFORM TO APPLICABLE ELECTRICAL CODES.
CONNECTING ELECTRICAL POWER CIRCUIT TO REMOTE CONDENSER COIL AND FAN ASS’Y (IF
APPLICABLE) see Figures 6 and 15)
CAUTION: The Cooling Unit refrigeration system is cooled by a Remote Condenser Coil
and Fan Assembly (P/N 309602000) that is authorized by IMI Cornelius Inc. Use of an
unauthorized Remote Condenser Coil and Fan Assembly will automatically void the
Cooling Unit factory warranty.
Remote Condenser Coil and Fan Assembly (P/N 309602000)
NOTE: Electrical power circuit may be connected to the Remote Condenser Coil and Fan Assembly
(P/N 309602000) in two ways. The preferred way is to draw electrical power from the Cooling Unit
contactor which allows the Remote Condenser Coil and Fan assembly to operate only when the
Cooling Unit refrigeration system is operating. The optional way is to connect a separate electrical
power circuit (independent of the cooling unit) through an appropriately rated and fused disconnect
switch or an equivalent HACR circuit breaker which allows the Remote Condenser Coil and Fan
Assembly to operate at all times (independent of Cooling Unit operation).
Connect and route electrical power circuit cable from Remote Condenser Coil and Fan Assembly through fuse
box (not provided), fused at 15-amps (maximum) down to Cooling Unit location. REMOTE CONDENSER COIL
AND FAN ASSEMBLY MUST BE PROPERLY GROUNDED, POWER CIRCUIT MUST BE MADE UP OF
COPPER CONDUCTORS, AND ALL WIRING MUST CONFORM TO NATIONAL AND LOCAL ELECTRICAL
CODES.
A. Remove four screws securing electrical control box to Cooling Unit back panel, (see Figure 6) then
pull control box out for access to contactor inside box.
B. Route Remote Condenser Coil and Fan Assembly power cable electrical wires through electrical
handy box on back of Cooling Unit to inside of electrical control box.
C. Connect Remote Condenser Coil and Fan Assembly power cable electrical wires to T
1
and T
2
terminals on contactor inside Cooling Unit electrical control box.
