DESCRIPTION
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
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 capability (field
convertible)
• Belt Drive Blower Motor with high static drive option
• Constant supply air volume (CV) with optional variable air
volume (VAV)
• Manufactured under the quality standards of ISO9001
• Simplicity® Control Board
• Zero-25% fixed air damper with hood
• Copper tube/aluminum fin coils
• Hinged filter access and toolless latched doors
• Rigging holes in base rails for lifting
• Single point power connection
• Complete factory package - tested, charged and wired
• CSA agency approvals on all units
WARRANTY
• One-year parts warranty
• A Five-year parts warranty on the compressors and
electric heat elements
• Ten-year parts warranty on the gas-fired heat exchangers
