D. GROUNDING

THE UNIT MUST BE PERMANENTLY GROUNDED. A
GROUNDING LUG IS PROVIDED IN THE ELECTRIC
HEAT ACCESS AREA FOR A GROUND WIRE. FAILURE
TO GROUND THIS UNIT CAN RESULT IN FIRE OR
ELECTRICAL SHOCK CAUSING PROPERTY DAMAGE,
SEVERE PERSONAL INJURY OR DEATH.

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 heat
pump thermostat package CAREFULLY because each has
some different wiring requirements.

XIII. INDOOR AIR FLOW DATA

Belt-drive blower models have motor sheaves set for proper
CFM at a typical external static. See Airflow Data Tables to
determine if adjustments are necessary.

XIV. CRANKCASE HEAT

Crankcase heat is standard on 7

1

⁄

2

& 10 ton models. The auxil-

iary switch on the compressor contactor turns off the heater
when the compressor is running.

XV. 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 7.)

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?

8. Is unit elevated to allow for outdoor coil condensate

drainage during heating operation and defrost?

XVI. STARTUP

1. Turn thermostat to “OFF,” turn “on” power supply at discon-

nect switch.

2. Turn temperature setting as high as it will go.
3. Turn fan switch to “ON.”
4. Indoor blower should run. Be sure it is running in the right

direction.

5. Turn fan switch to “AUTO.” Turn system switch to “COOL”

and turn temperature setting below room temperature. Unit
should run in cooling mode after 5 minute compressor on-
delay has expired.

6. Are outdoor fans operating correctly in the right direction?
7. Is compressor running correctly.
8. Turn thermostat system switch to “HEAT.” Unit should stop.

Raise temperature setting to above room temperature. Unit
should run in heating mode after 5 minute delay. Auxiliary
heaters, if installed, will energize 30 to 50 seconds after the
initiation of a “W3” call.

9. Check the refrigerant charge using the instructions located

on compressor access panel cover. Replace service port
caps. Service port cores are for system access only and
will leak if not tightly capped.

10. Turn thermostat system switch to proper mode “HEAT” or

“COOL” and set thermostat to proper temperature setting.
Record the following after the unit has run some time.
