GENERAL

YORK® Predator MagnaDRY™ units are single package air
conditioners with optional gas heating designed for outdoor
installation on a rooftop or slab and for non-residential use.
These units can be equipped with factory or field installed
electric heaters for heating applications.

These 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 supply (where applicable), and duct con­nections. The electric heaters have nickel-chrome elements
and utilize single-point power connection.

Ductwork should be designed and sized according to the
methods in Manual D of the Air Conditioning Contractors of
America (ACCA) or as recommended by any other recog­nized authority such as ASHRAE or SMACNA.

A closed return duct system should be used. This will 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 pressure requirements of the job. They
should NOT be sized to match the dimensions of the duct
connections on the unit.

Refer to Figure 14 for bottom air duct openings. Refer to Fig­ure 15 and 16 for rear air duct openings.

DUCT COVERS

Units are shipped with the side duct openings covered and a
covering over the bottom of the unit. For bottom duct applica­tion, no duct cover changes are necessary. For side duct
application, remove the side duct covers and install over the
bottom duct openings. The panels removed from the side
duct connections are designed to be reused by securing each
panel to its respective downflow opening. But keep in mind
that the supply panel is installed with the painted surface UP,
facing the heat exchanger, while the return panel is installed
with the painted surface DOWN, facing the downflow duct
opening. The supply panel is secured with the bracket
(already in place from the factory) and two screws. It’s a snug
fit for the panel when sliding it between the heat exchanger
and unit bottom, but there is room. The return panel is
secured with four screws.

CONDENSATE DRAIN

The side condensate drain is reversible and maybe re-ori­ented to the rear of the cabinet to facilitate condensate pip­ing. A condensate drain connection is available throug h the
base pan for piping inside the roof curb. Trap the connection
per Figure 22. The trap and drain lines should be p rotected
from freezing.

Plumbing must conform to local codes. Use a sealing com­pound on male pipe threads. Install condensate drain line
from the 3/4 inch NPT female connection on the unit to an
open drain.

COMPRESSORS

The compressors are mounted on elastomer insulators. The
mounting bolts have been fully tightened for shipping.

Do not loosen the compressor mounting bolts.

FILTERS

Two-inch filters are supplied with each unit. One-inch filters
may be used with no modification to the filter racks. Filters
must always be installed ahead of evaporator coil and must
be kept clean or replaced with same size and type. Dirty fil­ters reduce the capacity of the unit and result in frosted coils
or safety shutdown. All units use four (4) 20”x25”x2” filters.
The unit should not be operated without filters properly
installed.

Make sure that panel latches are properly positioned
on the unit to maintain an airtight seal.

THERMOSTAT WIRING

The thermostat should be located on an inside wall approxi­mately 56 inch above the floor where it will not be subject to
drafts, sun exposure or heat from electrical fixtures or appli­ances. Follow the manufacturer's instructions enclosed with
thermostat for general installation procedure. Seven (7) color­coded, insulated wires should be used to connect the thermo­stat to the unit. Refer to Table 7 for control wire sizing and
maximum length.

Avoid damage to internal components if drilling
holes for disconnect mounting.

NOTE: Since not all local codes allow the mounting of a dis-

connect on the unit, please confirm compliance with
local code before mounting a disconnect on the unit.

POWER AND CONTROL WIRING

Field wiring to the unit, fuses, and disconnects must conform
to provisions of National Electrical Code (NEC), ANSI/NFPA
No. 70 – Latest Edition (in U.S.A.), current Canadian Electri­cal Code C221, and/or local ordinances. The unit must be
electrically grounded in accordance with NEC and CEC as
specified above and/or local codes.

Voltage tolerances which must be maintained at the com­pressor terminals during starting and running conditions are
indicated on the unit Rating Plate and Table 1.

The internal wiring harnesses furnished with this un it are an
integral part of the design certified unit. Field alteration to
comply with electrical codes should not be required. If any of
the wire supplied with the unit must be replaced, replacement
wire must be of the type shown on the wiring diagram and the
same minimum gauge as the replaced wire.

A disconnect must be utilized for these units. Factory
installed disconnects are available. If installing a disconnect

(field supplied or York International
refer to Figures 4 and 5 for the recommended mounting loca­tion.

®

supplied accessory),

Electrical line must be sized properly to carry the load. USE
COPPER CONDUCTORS ONLY. Each unit must be wired
with a separate branch circuit fed directly from the meter
panel and properly fused.

Refer to Figure 23 for typical field wiring and to the app ropri­ate unit wiring diagram mounted inside control doors for con­trol circuit and power wiring information.

When connecting electrical power and control wiring
to the unit, water-proof connectors must be used so
that water or moisture cannot be drawn into the unit
during normal operation. The above water-proofing
conditions will also apply when installing a field sup­plied disconnect switch.

POWER WIRING DETAIL

Units are factory wired for the voltage shown on the unit
nameplate. Refer to Electrical Data Tables 8 to 13 to size
power wiring, fuses, and disconnect switch.

Power wiring is brought into the unit through the side of the
unit or the basepan inside the curb.
