Unit without Thru--Base Connection Kit —

Pass the thermostat control wires through the bushing on the

unit end panel. Route the wire through the snap--in wire tie

and up to the web bushing near the control box.. Route the

wire through the bushing and into the bottom left side of the

control box after removing one of the two knockouts in the

corner of the box. Use a connector at the control box to

protect the wire as it passes into the control box. Pull the

wires over to the terminal strip at the upper left corner of the

Central Terminal Board (CTB). Use the connector at the

control box and the wire tie to take up any slack in the

thermostat wire to ensure that it will not be damaged by

contact with the condenser coil. See Fig. 39.
NOTE:

If thru--the--bottom connections accessory is

used, refer to the accessory installation instructions for

information on routing power and control wiring.
