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.

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 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 - Y ork’ s Sunline™ series uni ts of fer factory
mounted BAS controls such as Simplicity

CO2 sensor to perform Differential Demand Ventilation.
It uses a Patented Comfort Ventilation algorithm to provide comfortable ventilation air temperature. The patented economizer-loading algorithm will protect the
equipment when harsh operating conditions exist.
Humidity in the occupied space or return duct can be
monitored and controlled via humidity sensors and the
on-board connection for hot gas re-heat system. It uses
the INTELLI-Start™ algorithm to maximize energy savings by recovering the building from the Unoccupied Setpoints to the Occupied Setpoints just in time for the

motor power input is 0.36kW. Refer to the SUPPLY AIR BLOWER PERFORMANCE Table for the kW of the supply air blower motor.
2. These capacities are gross ratings. For net capacity, determine the kW of the supply air blower motor from the SUPPLY AIR BLOWER
PERFORMANCE Table, multiply this value by 3.425 MBH/kW to determine the motor heat, and deduct this heat from the gross capacity
of the unit.

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.

set on steel beams above a finished roof. Cooling only, cooling
with gas heat and cooling with electric heat models are available
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 provide years of
dependable operation. All models (including those with an economizer) are suitable for either bottom or horizontal duct connections. Models with power exhaust are suitable 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 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
units are convertible single package
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 elements
