Casters
Open the front and rear doors. For each leveling foot, place an appropriately sized wrench on the hex head that
extends directly above the leveling foot. Turn the wrench clockwise to extend the leveling foot until it makes rm
contact with the oor. In the event of an uneven surface, each foot may need individual adjustment to level the
equipment. Cooling unit should be leveled to within .125 inch (3 mm) in both directions.
Potentially dangerous and lethal voltages exist within this unit.
Always disconnect electrical power supplies before leveling or
servicing.

ELECTRICAL CONNECTIONS
The following electrical connections are required in the eld:
• Power
• Controls (motor control card)
• Optional condensate pump is powered by the unit. Separate connection is not required.
All electrical connections must be in accordance with local and national codes and regulations.
Refer to electrical wiring diagram for power, controls and condensate pump connection points.
See the equipment nameplate for voltage and current requirements.
All low voltage connections must be made with properly insulated wires.
Line voltage and low voltage or control wires need to be in separate conduits.
MOTOR CONTROL CARD CONNECTION
Motor speed is controlled by an external control signal. A terminal is provided in the electrical control panel for
this connection.
Refer to electrical wiring diagram on the inside of the electrical panel for power, controls and condensate pump
connection points.
MINIMUM AND MAXIMUM OPERATING CONDITIONS
Unit is designed for indoor operation. Facilities with hot aisle temperatures outside the range of 80 F (27 C) -
115 F (46 C) and entering chilled water temperatures at 44 F (7 C) - 64 F (18 C) should consult nVent Technical
Products. Maximum water draining pressure is 125 PSI.
CONDENSATE PUMP WIRING
Refer to electrical wiring diagram on the inside of the electrical panel for power, controls and condensate pump
connection points.
WATER QUALITY
Chilled water loop must be kept clean of dirt, sediment and corrosive elements. System strainers or lter are
recommended. Chilled water system must be vented to insure air is not trapped in the piping or coils.
