☐ 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.

IImmppoorrttaanntt:: 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.
NNoottee:: 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 (refer to Figure 12, p. 18 for high and low
volt. conduits location). 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.
