Features and Benefits

Standard Features

•High Efficiency - High efficiency units reach as high as

10.9 EER. Gas/electric units have electronic spark ignition

and power vented combustion with steady state efficiencies

of 80%.

•Balanced Heating -

•Gas Heat - All gas heat units are built with two heating

sections for two equal stages of capacity control. 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 - All electric heat models (factory installed

only) 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 current

and temperature by fuses and two thermal limit switches.

The power supply wiring can be routed into the control

box through a threaded pipe connection in the base pan

of the unit or through a knockout in the wiring panel on

the front of the unit.

•BAS Controls - York’s Sunline™ series units offer factory

mounted BAS controls such as Simplicity

® Intelli-Comfort

II

™, Novar, Honeywell, Johnson, York Commercial

Comfort System (YCCS) and CPC.

•Convertible Airflow Design - All models (including those

with an economizer) are suitable for either bottom or

horizontal duct connections. Models with factory

installed power exhaust are suitable for bottom duct

connections only. For bottom duct, you remove the sheet

metal panels from the supply and return air openings

through the base of the unit. For horizontal duct, you

replace the supply and return air panels on the rear of the

unit with a side duct flange accessory.

•Factory Mounted Outdoor Air Dampers - All models are

available with these "factory mounted" outdoor air damper

options:

• Single enthalpy economizer with or without power

exhaust

• BAS-ready economizer with or without power exhaust

• Motorized outdoor air damper

• Barometric Relief Damper

A fixed outdoor air intake assembly will be shipped in the

return air compartment of all units ordered without an

economizer or motorized outdoor air damper option. The

assembly includes a rain hood with a damper that can be set

for 10, 15 or 25% outdoor air. With bottom duct connections,

the fixed outdoor air intake assembly should be mounted

over the opening in the return air panel. With horizontal

ductwork, it should be mounted on the return air duct.

•System Protection - Suction line freezestats are supplied

on all units to protect against loss of charge and coil frosting

when the economizer operates at low outdoor air

temperatures while the compressors are running. Every unit

has solid-core liquid line filter-driers and high and low-

pressure switches. Internal compressor protection is

standard on all compressors. Phase Monitors are optional

on all units. This accessory monitors the incoming power to

the unit and protects the unit from phase loss and reversed

phase rotation.

•Advanced Controls - Simplicity™ ZF 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

0F 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.

•Lead-Lag - An integrated Lead-Lag option allows equal

run time hours on all compressors, thereby extending

the life of all compressors. This option is selectable on

the unit control board.

•Fan Delays - Fan on and fan off delays are fully

programmable. Furthermore, the heating and cooling

fan delay times 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 and electric heat units. The unit control board will

alarm on ignition failures, compressor lockouts and

repeated limit switch trips.

•Nuisance Trip Protection and Strikes - To prevent

nuisance trouble calls, the control board uses a “three

The Simplicity® control board used in this product

will effectively operate the cooling system down to

25°F when this product is applied in a comfort

cooling application for people. An economizer is

typically included in this type of application. When

applying this product for process cooling applications

(computer rooms, switchgear, etc.), please

times, 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 associated 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.

•Reliable - From the beginning - All units undergo

computer automated testing before they leave the factory.

Units are tested for refrigerant charge and pressure, unit

amperage, and 100% functionality. For the long term - All

units are painted with a long lasting, powder paint that

stands up over the life of the unit. The paint used has

been proven by a 1000 hour salt spray test.

•Full Perimeter Base Rails - The permanently attached

base rails provide a solid foundation for the entire unit and

protect the unit during shipment. The rails offer rigging

holes so that an overhead crane can be used to place the

units on a roof.

•Easy Installation - Gas and electric utility knockouts are

supplied in the unit underside as well as the side of the

unit. Utility connections can be made quickly and with a

minimum amount of field labor. All units are shipped with

2" throw-away filters installed.

•Wide Range of Indoor Airflows - All supply air blowers

are equipped with a belt drive that can be adjusted to

meet the exact requirements of the job.

•Warranty - All models include a 1-year limited warranty

on the complete unit. Compressors and electric heater

elements each carry a 5-year warranty. Aluminized steel

and stainless steel tubular heat exchangers carry a 10-

year warranty.

2. Deduct these values from the available external static pressure shown in the respective Blower Performance Tables.

3. The pressure drop through the economizer is greater for 100% outdoor air than for 100% return air. If the resistance of the

return air duct is less than 0.25 IWG, the unit will deliver less CFM during full economizer operation.

Drive Selection

1. Determine side or bottom supply duct application.

2. Determine desired airflow

3. Calculate or measure the amount of external static pressure.

4. Using the operating point determined from steps 1, 2 & 3, locate this point on the appropriate supply air blower performance

table. (Linear interpolation may be necessary.)

5. Noting the RPM and BHP from step 4, locate the appropriate motor and/or drive on the RPM selection table.

6. Review the BHP compared to the motor options available. Select the appropriate motor and/or drive.

7. Review the RPM range for the motor options available. Select the appropriate drive if multiple drives are available for the

chosen motor.

8. Determine turns open to obtain the desired operation point.

Example

1. 6800 CFM

2. 2.0 iwg

3. Using the supply air blower performance table below, the following data point was located: 1020 RPM & 5.92 BHP.

4. Using the RPM selection table below, Size X and Model Y is found.

5. 5.92 BHP exceeds the maximum continuous BHP rating of the 5.0 HP motor. The 7.5 HP motor is required.

6. 1020 RPM is within the range of the 7.5 HP drives.

7. Using the 7.5 HP motor and drive, 3.5 turns open will achieve 1020 RPM.
