GENERAL
YORK Model D(CE, CG) and D(HE, HG) units are
either single package cooling units or single package
gas-fired central heating furnaces with cooling unit.
Both are designed for outdoor installation on a rooftop
or slab.
The units are completely assembled on rigid, perma-
nently attached base rails. All piping, refrigerant
charge, and electrical wiring is factory installed and
tested. The units require electric power, gas connec-
tion, duct connections, installation of combustion air
inlet hood, flue gas outlet hoods and fixed outdoor air
intake damper (units without economizer or motorized
damper option only) at the point of installation.
The supplemental field installed electric heaters have
nickel-chrome elements and utilize single point power
connection.
The gas-fired heaters have aluminized-steel tubular
heat exchangers. The units have spark ignition with
proven pilot. All gas heaters are shipped from the fac-
tory equipped for natural gas use, but can be field con-
verted to L.P./ Propane with Kit Model # 1NP0440.
SAFETY CONSIDERATIONS
Due to system pressure, moving parts and electrical
components, installation and servicing of air condition-
ing equipment can be hazardous. Only qualified,
trained, service personnel should install, repair, main-
tain or service this equipment.
Observe all precautions in the literature, on labels and
tags accompanying the equipment whenever working
on air conditioning equipment. Be sure to follow all
other safety precautions that apply.
Wear safety glasses and work gloves, and follow all
safety codes. Use a quenching cloth and have a fire
extinguisher available for all brazing operations.
INSPECTION
As soon as a unit is received, it should be inspected for
possible damage during transit. If damage is evident,
the extent of the damage should be noted on the car-
rier's freight bill. A separate request for inspection by
the carrier's agent should be made in writing. Refer to
Form 50.15-NM for additional information.
