GENERAL
YORK Model DJ units are either single package air
conditions equipped with optional factory installed electric heaters, or single package gas-fired central heating
furnaces with cooling unit. Both are designed for outdoor installation on a rooftop or slab.
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 electric power, gas connection, duct connections, installation of combustion air
inlet hood, flue gas outlet hoods and fixed outdoor air
intake damper (units without ec onomizer or motorized
damper option only) at the point of installation.
The supplemental electric heaters have nickel-chrome
elements and utilize single point power connection.
These gas-fired heaters have aluminized-steel or
optional stainless steel, tubular heat exchangers with
spark ignition with proven pilot. All gas heaters are
shipped from the factory equipped for natural gas use,
but can be field converted to L.P./ Propane with Kit
Model # 1NP0418. See Gas Heat Application Data
Table.

Unitary Products Group19
Do not permit overhanging structures or shrubs
to obstruct outdoor air discharge outlet, combustion air inlet or vent outlets.
DUCTWORK
Ductwork should be designed and sized according to
the methods in Manual Q of the A ir Conditioning Contractors of America (ACCA).
A closed return duct system shall be used. This shall
not preclude use of economizers or outdoor fresh air
intake. The supply and return air duct connections at
the unit should be made with flexible joints to minimize
noise.
The supply and return air duct systems should be
designed for the CFM and static requirements of the
job. They should NOT be sized to match the dimensions of the duct connections on the unit.
When fastening ductwork to side duct flanges
on unit, insert screws through duct flanges
only. DO NOT insert screws through casing.
Outdoor ductwork must be insulated and
waterproofed.
Refer to Dimensions and Clearances Figure 13 for
information concerning side and bottom supply and
return air duct openings.
66352-YIM-D-0904
FIXED OUTDOOR AIR INTAKE DAMPER
This damper is shipped inside the return air compartment. It is completely assembled and ready for installation. A damper baffle inside of the hood is adjustable to
provide variable amounts of outdoor air intake on units
that are not provided with an economizer or a motorized damper option. Refer to the Fixed Outdoor
Damper Figure 3.
Gasketing and mounting screws are provided in a parts
bag attached to the hood assembly. Apply gasketing to
the three flange surfaces on the hood prior to installing
the hood. Extend gasketing 1/4 inch beyond the top
and bottom of the two side flanges to insure adequate
sealing.
Adjusting the damper to the desired air flow may be
done before mounting the hood into position or after
installation by removing the front hood panel or the
screen on the bottom of the hood. Damper baffle in
position 1 will allow approximately 10% outdoor air
flow, position 2 approximately 15% and, to allow
approximately 25%, remove the damper baffle.
On units with bottom return air application install the
damper assembly over the opening in the side return
air access panel. Remove and discard the opening
cover and the covering over the hood mounting holes
(used for shipping) before installing. Secure with the
screws provided.
On units with side return air applications, install the
damper assembly on the return air ductwork as close
to the unit as possible. Cut an opening 16 inches high
by 18 inches wide in the ductwork to accom m o da te the
damper. Using the holes in the hood flanges as a template, drill 9/64 inch dia. (#26 drill) holes into the ductwork and secure with the screws provided.
NOTE: It is recommended that, in Canada, the outlet
duct be provided with a removable access
panel. It is recommended that this opening be
accessible when the unit is installed in service,
and of a size such that smoke or reflected light
may be observed inside the casing to indica te
the presence of leaks in the heat exchanger.
The cover should be attached in a manner
adequate to prevent leakage.
20Unitary Products Group
If outdoor air intake will not be required on
units with bottom return air applications, the
damper assembly should still be mounted on
the side return air access panel, per the
instructions above, to insure moisture is not
drawn into the unit during operation. The covering over the mounting holes only need be
removed. Do not remove the opening cover.

CONDENSATE DRAIN
COMPRESSORS
Units are shipped with compressor mountings factoryadjusted and ready for operation.
Do not loosen compressor mounting bolts.
FILTERS
Two-inch filters are supplied with each unit, but units
can be converted easily to four-inch filters. Filters must
always be installed ahead of the evaporator coil and
must be kept clean or replaced with same size and
type. Dirty filters will reduce the capacity of the unit and
will result in frosted coils or safety shutdown. Minimum
filter area and required sizes are shown in Physical
Data Table 7.
Plumbing must conform to local codes. Use a sealing
compound on male pipe threads. Install a condensate
drain line from the one-inch NPT female connection on
the unit to an open drain.
NOTE: The condensate drain operates in a negative
pressure in the cabinet. The condensate drain
line MUST be trapped to provide proper drainage. See Figure 4.
