York D2CG300 User Manual

Due to system pressure, moving parts and electrical components,
installation and servicing of air conditioning equipment can be
hazardous. Only qualified, trained, service  personnel should
install, repair, maintain or service this equipment.
‘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:

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
