GROUNDING MAY ALSO BE ACCOMPLISHED BY

GROUNDING THE POWER LINE CONDUIT TO THE

UNIT. MAKE SURE THE CONDUIT NUT LOCKING TEETH

HAVE PIERCED THE INSULATING PAINT FILM OF THE

SIDE PANEL.

E. THERMOSTAT

The thermostat should be mounted on an inside wall about

five feet above the floor in a location where it will not be

affected by unconditioned air, sun, or drafts from open doors

or other sources. READ installation instructions in air condi-

tioner thermostat package CAREFULLY because each has

some different wiring requirements.

XII. INDOOR AIR FLOW DATA

Belt-drive blower models have motor sheaves set for proper

CFM at a typical external static. See Tables C through G for

blower performance.

XIII. CRANKCASE HEAT (OPTIONAL)

Crankcase heaters are standard on 6 ton and single stage 71⁄2.

Crankcase heat is not required on other models, but may be

desirable under certain conditions.

XIV. PRE-START CHECK

1. Is unit properly located and slightly slanted toward indoor

condensate drain?

2. Is ductwork insulated, weatherproofed, with proper spacing

to combustible materials?

3. Is air free to travel to and from outdoor coil? (See Figure 4.)

4. Is the wiring correct, tight, and according to unit wiring dia-

gram?

5. Is unit grounded?

6. Are field supplied air filters in place and clean?

7. Do the outdoor fan and indoor blower turn freely without

rubbing, and are they tight on the motor shafts?
