TECHNICAL GUIDE Description

YORK® ZF Series Sunline™ units are convertible single
R-410A package high efficiency rooftops. All models have independent
refrigeration circuits for efficient part load operation.
ZF SERIES Although the units are primarily designed for curb mounting on
15 & 20 TON a roof, they can also be slab-mounted at ground level or set on
steel beams above a finished roof.
50 Hertz All ZF units are self-contained and assembled on rigid full
perimeter base rails allowing for overhead rigging. Every unit is
completely charged, wired, piped, and tested at the factory to
provide a quick and easy field installation.

All models (including those with an economizer) are convertible

between bottom and horizontal duct connections.

ZF units are available in the following configurations: cooling

only, cooling with electric heat, and cooling with gas heat.
Electric heaters are available as factory-installed options only.

1. Add these values to the available static resistance in the respective Blower Performance Tables.
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.
