INSTALLATION INSTRUCTION
GENERAL
YORK Model DCE units are single package air conditioners
designed for outdoor installation on a rooftop or a slab. Electric
heaters are available as field-installed accessories.
The units are completely assembled on rigid, permanently
attached base rails. All piping, refrigerant charge, and electrical
wiring is factory-installed and tested. The units require only
electric power and duct connections at the point of installation.
The electric heaters have nickel-chrome elements and utilize
single point power connection.
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. See Local Distributor for additional information.
Installer should pay particular attention to the words: NOTE, CAUTION and WARNING . Notes are intended to clarify or
make the installation easier. Cautions are given to prevent equipment damage. Warnings are given to alert installer that per-
sonal injury and/or equipment damage may result if installation procedure is not handled properly.
