GUIDE SPECIFICATIONS
GENERAL
Units shall be manufactured by Johnson Controls Unitary
Products in an ISO 9001 certified facility.
York's Sunline 2000
TM
units are convertible single package-
units. Although the units are primarily designed for curb mount-
ing on a roof, they can also be slab-mounted at ground level or
set on steel beams above a finished roof. Cooling only, cooling
with gas heat and cooling with electric heat models are avail-
able with a wide variety of factory-mounted options and field-
installed accessories to make them suitable for almost every
application. All units are self-contained and assembled on full
perimeter base rails with holes in the four corners for overhead
rigging. Every unit is completely piped, wired, charged and
tested at the factory to simplify the field installation and to pro-
vide years of dependable operation. All models (including
those with an economizer) are suitable for either bottom or hor-
izontal duct connections. Models with power exhaust are suit-
able for bottom duct connections only. For bottom duct,
remove the sheet metal panels from the supply and return air
openings through the base of the unit. For horizontal duct,
remove the supply and return air panels on the rear of the unit.
All non-Scroll compressors include crankcase heaters and all
compressors have internal pressure relief. Every refrigerant
circuit includes a liquid line filter-drier, a discharge line high
pressure switch and a suction line with a freezestat and low
pressure/loss of charge switch.The unit control circuit
includes a 75 VA transformer, a 24-volt circuit breaker and a
relay board with a compressor lockout circuit, a terminal strip
for thermostat wiring, plus an additional set of pin connectors
to simplify the interface of additional field controls. All units
have long lasting powder paint cabinets with 1000 hour salt
spray test approval under ASTMB117 procedures. All models
are CSA listed. All models include a 1-year limited warranty
on the complete unit. Compressors and electric heater ele-
ments carry a 5-year warranty. Aluminized steel and Stainless
steel tubular heat exchangers carry a 10-year warranty.
DESCRIPTION
Units shall be factory-assembled, single packaged, Electric
Cooling/Gas Heat, Electric Cooling/Optional Electric Heat
and designed for outdoor mounted installation.
The 6 ton unit shall have minimum EER ratings of 9.0. They
shall have built-in field convertible duct connections for down
discharge supply/return or horizontal discharge supply/return,
and be available with factory installed options or field installed
accessories. The units shall be factory wired, piped, charged
with R-22 refrigerant and factory tested prior to shipment. All
unit wiring shall be both numbered and color coded. All units
the cooling performance shall be rated in accordance with
DOE and ARI test procedures. Units shall be CSA listed,
classified to ANSI Z21.47, UL 1995/CSA No. 236 standards.
UNIT CABINET
Unit cabinet shall be constructed of galvanized steel, with exte-
rior surfaces coated with a non-chalking, powdered paint finish,
certified at 1000 hours salt spray test per ASTMB117 standards.
Indoor blower section shall be insulated with a minimum 1/2”
thick insulation, coated on the airside. Aluminum foil faced insu-
lation shall be used in the furnace compartment and be fastened
with ridged fasteners to prevent insulation from entering the air
stream. Cabinet panels shall be “large” size, easily removable
for servicing and maintenance. Full perimeter base rails shall be
provided to assure reliable transit of equipment, overhead rig-
ging and proper sealing on roof curb applications. Disposable 1"
filters shall be furnished and be accessible through a removable
access door, sealed airtight. Units filter track shall be designed
to accommodate either 1” or 2” filters. Fan performance measur-
ing ports shall be provided on the outside of the cabinet to allow
accurate air measurements of evaporator fan performance with-
out removing panels or creating air by-pass of the coils. Conden-
sate pan shall be internally sloped and conform to ASHRAE 62-
89 self-draining standards. Condensate connection shall be a
minimum of 3/4” I.D. female and be a ridged mount connection.
INDOOR (EVAPORATOR) FAN ASSEMBLY
The indoor fan shall be direct drive, multi-speed, or a factory
installed belt drive assembly that includes an adjustable pitch
motor pulley. Job site selected brake horsepower (B.H.P.) shall
not exceed the motors nameplate horsepower rating, plus the
service factor. Units shall be designed not to operate above
service factor. Fan wheel shall be double-inlet type with for-
ward-curved blades, dynamically balanced to operate
smoothly throughout the entire range of operation. Airflow
design shall be constant air volume. Bearings shall be sealed
and permanently lubricated for longer life and no maintenance.
OUTDOOR (CONDENSER) FAN ASSEMBLY
The outdoor fan shall be of the direct-driven propeller type,
discharge air vertically, have aluminum blades riveted to a
corrosion resistant steel spider bracket and shall be dynami-
cally balanced for smooth operation. The outdoor fan motor
shall be totally enclosed with permanently lubricated bear-
ings, internally protected against overload conditions and
staged independently.
REFRIGERANT COMPONENTS
Compressor:
a. Shall be internally protected with internal high-pres-
sure relief and over temperature protection.
b. Shall have internal spring isolation and sound muf-
fling to minimize vibration and noise, and be exter-
nally isolated on a dedicated, independent mounting.
Coils:
a. Evaporator and condenser coils shall have alumi-
num plate fins mechanically bonded to seamless
internally enhanced copper tubes with all joints
brazed. Special Phenolic coating shall be available
as a factory option.
b. Evaporator and Condenser coils shall be of the direct expansion, draw-thru, design.
