INSTALLATION INSTRUCTION
208/230/575
VOLT ONLY
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.
S u pp l em e nt a l e l ec t ri c h ea te rs fo r D C E u ni ts ha ve
nickel-chrome elements and utilize single point power
connections.
The following safety precautions apply to DCG units:
FOR YOUR SAFETY
If you smell gas:
1. Open windows.
2. Don't touch electrical switches
3. Extinguish any open flame.
4. Immediately call your gas supplier.
Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any
other appliance
INSPECTION

530.18-N11Y HEAT ANTICIPATOR SETPOINTS It is important that the anticipator setpoint be correct. Too high of a setting will result in longer heat cycles and a greater temperature swing in the conditioned space. Reducing the value below the correct setpoint will give shorter “ON” cycles and may result in the lowering of the temperture within the conditioned space. -
