Convenience Receptacle/Section Lights

A Ground Fault Circuit Interrupter (GFCI) convenience
receptacle is provided in the main control box on all units. The
receptacle can either be field powered or unit powered. If it
is field powered, a field wired 120V circuit must be provided.
Refer to the Field Power Wiring
receptacle is unit powered, then no additional field wired 120V
circuit is required for it function.
If the optional service lights were included, the light switch will
be located near the GFCI receptacle. The lights are always
powered by the same source as the GFCI; either unit powered
or Field powered depending on the GFCI option selected.

Check, Test and Start Procedures

LOCKOUT/TAGOUT all power sources before servicing this equipment.
More than one disconnect may be required to de-energize unit.
Electric shock and moving components such as, fans, dampers, energy
recovery devices can cause serious injury, death and property damage.
All start-up and service work must be performed only by trained, experienced

Read and follow the all relevant manuals before operating or servicing.
Bond the equipment frame to the building electrical ground through
grounding terminal or other approved means.
All units are complete an end of line operation test at the
factory to promote proper operation in the field. Nevertheless,

Before Start-up
1. Verify that the unit is completely and properly installed
with ductwork connected.
2. Verify that all construction debris is removed, and that
the filters are clean.
3. Verify that all electrical work is complete and properl
terminated.
4. Verify that all electrical connections in the unit control
panel and compressor terminal box are tight, and that the
proper voltage is connected.
5. Verify all nameplate electrical data is compatible with the
power supply.
6. Verify the phase voltage imbalance is no greater than 3%.
7. Verify that gas piping is complete and leak tight.
8. Verify that the shutoff cock is installed ahead of the
furnace, and that all air has been bled from the gas lines.
9. Manually rotate all fans and verify that they rotate freely.
