DESCRIPTION
YORK Sunline MagnaDRY™ units are convertible sin-
gle package high efficiency rooftops. All models have
independent dual refrigerant 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 units include:
•
Powder Paint finish that meets ASTM-B-117 1000
hour salt spray standards
•
Two-stage cooling provided by dual independent
refrigeration circuits with expansion valves, filter-
driers, high and low pressure/loss of charge
switches and freezestats
•
Scroll compressors
•
Two-stage heating provided by dual independent
heat exchangers with aluminized steel tubes,
redundant gas valves, spark ignition with induced
draft logic
•
Permanently lubricated motors
•
Bottom or side air discharge configuration capabil-
ity (field convertible)
•
Belt Drive Blower Motor with high static drive
option
•
