TECHNICAL GUIDE Description
YORK'ZF/ZR/XP Series units are convertible single package
high efficiency rooftops with a common roof curb for the 3,4, 5
and 6 Ton sizes(ZR,XP not available in 6 Ton).Although the
units are primarily designed for curb mounting on a roof, they
can also be slab-mounted at ground level or set on steel beams
above a finished roof.
All ZF/ZR/XP Series 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.
R-410A All models(including those with an economizer)are convertible
ZF / ZR / XP SERIES between bottom and horizontal duct connections.
ZF/ZR Series units are available in the following configurations:
3 - 6 TON cooling only, cooling with electric heat, and cooling with one or
two stage gas heat. Electric heaters are available as factory-
60 Hertz installed option or field installed accessory.
XPS eries units are available in the following configurations:
cooling and heating only and cooling and heating with electric
heat.
