Checklist
Use the following checklist in conjunction with the general
checklist (
“General Unit Requirements,” p. 18
) to ensure
that the unit is properly installed and ready for operation.
WARNING
Hazardous Voltage!
Failure to disconnect power before servicing could
result in death or serious injury.
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Verify that no power is
present with a voltmeter.
☐
Check all electrical connections for tightness and “point
of termination” accuracy.
☐
Verify that the condenser airflow is unobstructed.
☐
Verify that the condenser fan and indoor blower turn
freely without rubbing and are properly tightened on the
shafts.
☐
Check the supply fan belts for proper tension and the
fan bearings for sufficient lubrication. If the belts require
adjustment, or if the bearings need lubricating, refer to
the maintenance section of this manual for instructions.
☐
Verify that a condensate trap is installed and the piping
is properly sized and pitched.
☐
Verify that the correct size and number of filters are in
place.
☐
Inspect the interior of the unit for tools and debris and
install all panels in preparation for starting the unit.

WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious
injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. Verify with a CAT III or IV
voltmeter rated per NFPA 70E that all capacitors have
discharged.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
Important:
All phases of this installation must comply with
NATIONAL, STATE, and LOCAL CODES. In
addition to local codes, the installation must
comply with National Electric Code - ANSI/
NFPA NO. 70 LATEST REVISION.
1. Field connections are made by first removing the
compressor access panel on the front of the unit.
Unscrew the assembly around the outside of the
disconnect switch. This assembly is located in the
condenser section of the unit.
Both high and low voltage power can be routed through
the base or through the front corner post where the
disconnect enclosure is mounted. The hole is sized for
1 1/2–in. conduit.
2. If the conduit required for your application is larger than
1 1/2–in., remove the termination plate and connect to
the larger hole using field supplied reducing washers.
3.
Route the power wires and ground conductor through
conduit and into the bottom of the factory installed
disconnect switch. Connect the power conductors to
the lugs provided. Connect the ground wire to the unit
ground lug.
Note:
Wire size for the length of run should be
determined using the circuit ampacity found on
the unit nameplate and the N.E.C.
4. Route low voltage (class II), control wiring through hole
in base of unit but not through high voltage conduit.
Feed control wiring through bushing provided on side
panel. Route wires through loose wire ties provided.
5. Tighten the wire ties. Secure the excess wire bundle
under the wire ties in the outdoor section. Do not leave
excess wire in the electrical enclosure. Use the unit
wiring diagram to make the low voltage connections.
