• Run the new 4-conductor cable from the

existing control box in the PolarCool
cabinet, through the cable connector, into
the External Control Box.

• Disconnect the wires from switches (or

circuit board if converting a variable speed
unit) in the existing control box. Connect
wires as shown in diagram at right.

NOTE: The existing switches may be left in place,

however, if removed, the holes should be
plugged.

NOTE: If using an External Control Box with a

Variable-Speed PolarCool, the PolarCool
will function as a single speed.
• Tie the 4-conductor, pump and motor

cables to the cabinet to prevent movement
of the cable during operation.

• Replace the evaporative pads removed in

Step 1 and secure the top of the
PolarCool cabinet.

• Mount the External Control Box in the

desired location taking into account the
distance between the External Control
Box and the PolarCool cabinet must be
reached with the supplied 4-conductor
cable.

• In the External Control Box connect the 4-

conductor cable to the lugs as shown in
diagram below. Then connect the power
cord removed in Step 2 to the lugs as
shown. Check the power cord for
abrasions or cuts. Discard and replace if
necessary.
