FEATURES
All models are available with a wide variety of factorymounted options such as electric heaters, phase monitor,
convenience outlet, dirty filter switch, disconnect switch,
smoke detectors, and coil guards to make them suitable for
almost every application.
All units are self-contained and assembled on full perimeter
base rails with forklift holes on three sides and holes for overhead rigging. Every unit is completely piped, wired, charged
and tested at the factory to simplify the field installation and to
provide years of dependable operation.
All models (including those with an economizer) are suitable
for either bottom or horizontal duct connections. 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 models are available with these “factory mounted” outdoor
air damper options:
•Single enthalpy economizer
•Motorized outdoor air damper
Supply air blowers are equipped with either a direct drive or a
belt drive that can be adjusted to meet the exact requirements of the job.
All compressors are equipped with internal pressure relief.
Every refrigerant circuit includes a liquid line filter-drier, a high
pressure switch and a suction line with a freezestat and low
pressure/loss of charge switch to protect all system components.
•Simplicity™ Controls - Simplicity™ control boards have
standardized a number of features previously available
only as options or by utilizing additional controls.
•Low Ambient - An integrated low-ambient control
allows all units to operate in the cooling mode down
to 0ºF outdoor ambient without additional assistance. Optionally , the control board can be programmed to lockout the compressors when the
outdoor air temperature is low or when free cooling
is available.
•Anti-Short Cycle Protection - To aid compressor
life, an anti-short cycle delay is incorporated into the
standard controls. Compressor reliability is further
ensured by programmable minimum run times. For
testing, the anti short cycle delay can be temporarily
overridden with the push of a button.
•Fan Delays - Fan on and fan off delays are fully programmable and are independent of one another. All
units are programmed with default values based
upon their configuration of cooling and heat.
•Safety Monitoring - The control board monitors the
high and low-pressure switches, the freezestats, the
gas valve, if applicable, and the temperature limit
switch on gas heat units. The unit control board will
alarm on ignition failures, compressor lockouts and
repeated limit switch trips.
•Nuisance Trip Protection- To prevent nuisance
trouble calls, the control board uses a “three strikes,
you’re out” philosophy. The high and low-pressure
switches and the freezestats must trip three times
within two hours before the unit control board will
lock out the compressor.
•On Board Diagnostics - Each alarm will energize a
trouble light on the thermostat, if so equipped, and
flash an alarm code on the control board LED. Each
high and low-pressure switch alarm as well as each
freezestat alarm has its own flash code. The control
board saves the five most recent alarms in memory,
and these alarms can be reviewed at any time.
Alarms and programmed values are retained
through the loss of power.
All units have long lasting powder paint cabinets with 750
hour salt spray test approval under ASTM-B117 procedures.
All models are CSA listed.
•Warranty - All models include a one-year limited parts
warranty on the complete unit. Compressors and electric
heater elements carry a five-year warranty
•Electric Heat Operation - All electric heat models are
wired for a single power source and include a bank of
nickel chromium elements mounted at the discharge of
the supply air blower to provide a high velocity and uniform distribution of air across the heating elements.
Every element is fully protected against excessive temperature by thermal limit switches.
The power supply wiring can be routed into the control
box through a threaded pipe connection (field supplied)
in the base pan of the unit or through a knockout in the
wiring panel on the side of the unit.
•BAS Controls - York’s Sunline™ series units offe r factory mounted BAS controls such as SImplicity™
INTELLI-Comfort™, Novar, Honeywell, Johnson, and
CPC.

matic reset to prevent the heating element system from operating at an excessive temperature. The heating section
assembly shall slide out of the unit for easy maintenance and
service. Units with Electric Heating shall be wired for a single
point power supply with branch circuit fusing (where
required).
UNIT OPERATING CHARACTERISTICS
a.Unit shall be capable of starting and running at
125°F outdoor temperature, exceeding maximum
load criteria of ARI Standard 210/240. The compressor, with standard controls, shall be capable of operation down to 0°F outdoor temperature. Unit shall be
provided with fan time delay to prevent cold air
delivery before heat exchanger warms up (Gas heat
only).
ELECTRICAL REQUIREMENTS
All unit power wiring shall enter unit cabinet at a single factory
provided location and be capable of side or bottom entry, to
minimize roof penetrations and avoid unit field modifications.
Separate side and bottom openings shall be provided for the
control wiring.
STANDARD LIMITED WARRANTIES
•Compressor 5 Years
•Electric Heat Element 5 Years
•Other Parts 1 Year
OPTIONAL OUTDOOR AIR (Shall be made available by
either/or):
•ELECTRONIC ENTHALPY AUTOMATIC ECONO-MIZER- Outdoor and return air dampers that are interlocked and positioned by a fully-modulating, spring
return damper actuator. The maximum leakage rate for
the outdoor air intake dampers shall not exceed 2%
when dampers are fully closed and operating against a
pressure differential of 0.5 IWG. A unit-mounted potentiometer shall be provided to adjust the outdoor and return
air damper assembly to take in CFM of outdoor air to
meet the minimum ventilation requirement of the conditioned space during normal operation. During economizer operation, a mixed-air temperature control shall
modulate the outdoor and return air damper assembly to
prevent the supply air temperature from dropping below
55°F. Changeover from compressor to economizer operation shall be provided by an integral electronic enthalpy
control that feeds input into the basic module. The outdoor intake opening shall be covered with a rain hood
that matches the exterior of the unit. Water eliminator/filters shall be provided. Simultaneous economizer/compressor operation is also possible. Dampers shall fully
close on power loss.
•MOTORIZED OUTDOOR AIR DAMPERS - Outdoor air
dampers are positioned by a 2-position, spring-return
damper actuator. The maximum leakage rate for the outdoor air intake dampers shall not exceed 2% when
dampers are fully closed and operating against a pressure differential of 0.5 IWG. A unit-mounted potentiometer shall be provided to adjust the outdoor damper
assembly to take in the design CFM of outdoor air to
meet the ventilation requirements of the conditioned
space during normal operation. Whenever the indoor fan
motor is energized, the dampers open up to one of two
pre-selected positions - regardless of the outdoor air
enthalpy. Dampers return to the fully closed position
when the indoor fan motor is de-energized. Dampers
shall fully close on power loss.
