Sunline 2000™ Heat Pumps are convertible single package
units. All models have 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.
These heat pumps utilize a unique ambient compensated time-
temperature defrost system. The defrost module automatically
increases the time interval between defrost cycles as the outdoor
ambient temperature decreases. This helps to eliminate unneces-
sary and costly defrosts.
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 pres-
sure/loss of charge switches and freezestats
• Hermetically sealed compressors with crankcase heaters
• Permanently lubricated motors
• Bottom or side air discharge configuration capability (field con-
vertible)
• Belt Drive Blower Motor
• Manufactured under the quality standards of ISO9001
• Twenty-four volt control circuit with compressor lock-out
• Zero-25% fixed air damper with hood
• Copper tube/aluminum fin coils
• Easy access to all components
• 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
• Factory Limited Parts Warranty
• One-year parts warranty
• A Five-year parts warranty on the compressor and
electric heat elements.
