INSTALLATION INSTRUCTIONS

trol kit

A.If your installation included the optional electric heat kit, install it at this time. Follow the instructions with the

heat package for its installation procedure.

B.Terminate the 4-conductor control cable(s) protruding into the 14-1/4” x 14-1/4” (±1/8”) roof opening. The cable(s) must be terminated with an RJ-11-4C-6P telephone

connector. Refer to the crimp tool manufacture for crimping instructions.

Important: RJ-11-4C-6P connectors must be installed as shown in FIG. 4A.

C.Remove the junction box cover from the Electronic

Control Kit. See FIG. 11.

D.Plug the electrical conduit (6-pin connector) from the upper unit into the mating connector in Electronic Con-

trol Kit. See FIG. 11.

FIG. 11

E.Plug the control cable(s) into the telephone jack(s) on the Electronic Control Kit. (It does not matter which one.)

F.Route the Remote Temperature Sensor cable, if appli- cable, through the same round grommet where freeze control wires go into the Electronic Box. See FIG. 11. Connect it to the connector that matches its color.

G.Insert the Freeze Control Sensor approximately 1” into the evaporator coil fins as shown in FIG. 12.

8. Wiring of System

A. CONNECTION OF LOW VOLTAGE WIRES

Disconnect the positive (+) 12 volt DC terminal at the supply battery. Damage to equipment could occur if the 12 volt DC is not shut off.

1.Connect the previously run 12 VDC to the red and black wires protruding from the Electronic Control Kit.

(In multiple zone installations, this needs to be done at only one zone.) Connect +12 VDC to the red wire; -12 VDC to the black wire.

2.Connect the previously run furnace thermostat wires (if applicable) to the blue wires protruding from the

electronic Control Kit. The polarity of these connec- tions does not matter. If not used, terminate wire with twist connector.

3.Connect the previously run Energy Management System wires (if applicable) to the yellow wires protruding from the Electronic Control Kit. The

polarity of these	connections does not matter. If not
used, terminate	wire with twist connector.
