DESCRIPTION
TECHNICAL GUIDE
YORK Sunline MagnaDRY™ units are convertible single
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
SUNLINE MagnaDRY™
a roof, they can also be slab-mounted at ground level or set on
steel beams above a finished roof.
All units include:
GAS/ELECTRIC SINGLE
