York D1CE User Manual

GENERAL
YORK Model DCE and DCG units are single package air
conditioners designed for outdoor installation on a rooftop or a
slab and is manufactured under ISO 9002 Quality System
Certification. The DCE models are cooling only and can be
equipped with factory installed electric heaters for cooling /
heating applications. The DCG models are gas-fired central
heating furnaces with cooling.
The units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electrical
wiring is factory installed and tested. All units require electric
power, duct connections and fixed outdoor air intake damper
(units without economizer or motorized damper option only) at
the point of installation.
The DCG units additionally require gas connection, installation
of the combustion air inlet hood and the flue gas outlet hoods
at the point of installation. The gas-fired heaters have
aluminized-steel tubular heat exchangers and spark ignition
with proven pilot.
Supplemental electric heaters for DCE units have
nickel-chrome elements and utilize single point power
connections.
The following safety precautions apply to DCG units:
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 carrier’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.
