ZJ Series Sunline Magnum™ /ZR Series
MagnaDRY™/ZF Series Sunline™ units are convertible single
package high efficiency rooftops. All models have independent
refrigeration circuits for efficient part load operation.
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 ZJ/ZR/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.
ZJ/ZR/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.
Tested in accordance with:
