FEATURES
All models are available with a wide variety of factorymounted 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 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.

grammable and are independent of one another. All
units are programmed with default values based
upon their configuration of cooling and heat.
high and low-pressure switches, the freezestats, the
gas valve, if applicable, and the temperature limit
™ control boards have
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
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 section 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 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 offer factory
mounted BAS controls such as Simplicity™ INTELLIComfort™, Novar, Honeywell, Johnson, and CPC.

1. Deduct these resistance values from the available external static pressure shown in SUPPLY AIR BLOWER PERFORMANCE Tables.
2. Add these resistance values to the available static resistance values on 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.

stages of capacity - 16 KW and above on 208/230 volt heaters and 20 KW and above on 460
and 575 volt heaters. The
heating section shall have a primary limit control(s) and auto-
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 startingand runningat
125°F outdoor temperature, exceedingmaximum
load criteria of ARI Standard 210/240. The compres-
sor, 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 he
at 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.

OPTIONAL OUTDOOR AIR (Shall be made available by
Simplicity
either/or):
•ELECTRONIC ENTHALPY AUTOMATIC ECONO-
MIZER- Outdoor and return air dampers that are inter-
locked 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 operatingagainst a
pressure differential of 0.5 IWG.
A unit-mounted potenti-
ometer 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 condi-tioned space during normal operation. During econo-
mizer 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/com-
pressor operation is also possible. Dampers shall fully
close on power loss.
•MOTORIZED OUTDOOR AIR DAMPERS - Outdoor air
dampers
are positioned by a2-position, spring-return
damper actuator. The maximum leakage rate for the out-
door air intake dampers shall not exceed 2% when
dampers are fully closed and operatingagainst a pressure differential of 0.5 IWG. A unit-mounted potentiome-
ter 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
ce during normal operation. Whenever the indoor fan
spamotor 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.
