FEATURES
All models are available with a wide variety of factory-
mounted options such as stainless steel heat exchangers,
electric heaters, phase monitor, convenience outlet, dirty filter
switch, disconnect switch, smoke detectors, and coil guard 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 over-
head 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 horizon-
tal 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 require-
ments 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 compo-
nents.
•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 assis-
tance. Optionally, the control board can be pro-
grammed 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 pro-
grammable 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 1000
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. Gas heat
exchangers carry a 10-year parts warranty.
•Gas Heat Operation - All single phase models with gas
heat have minimum annual fuel utilization efficiency
(AFUE) of 80%. All three phase models with gas heat
have minimum steady state efficiency of 80%. Each sec-
tion includes a durable heat exchanger with aluminized
steel or optional stainless steel tubes, a redundant gas
valve, spark ignition, power venting, an ignition module for
100% shut-off and all of the safety controls required to
meet the latest ANSI standards.
The gas supply piping can be routed into the heating
compartment through a hole in the base pan of the unit
or through a knockout in the piping panel on the front of
the unit.
•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 uni-
form distribution of air across the heating elements.
Every element is fully protected against excessive tem-
perature 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 offer factory
mounted BAS controls such as Simplicity® INTELLI-Com-
fort™, Novar, Honeywell, Johnson, and CPC.

1. Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables.
3. The pressure through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the return air
duct system is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.
2. Add these resistance values to the available static resistance values on SUPPLY AIR BLOWER PERFORMANCE Tables.
