GENERAL

York Model DEM units are factory assembled cooling only air
conditioners designed for outdoor installation on a rooftop or a
slab. Field-installed electric heater accessories are available to
provide electric heat combined with electric cooling.
The units are completely assembled on rigid, but easily
removable 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 resistance wire
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.
