HS/HP29 Air Conditioners and Heat Pumps
Muscular performance and rugged durability.
Features and Benefits
Efficient operation
- Efficiency ratings of up to 11.50 SEER and 8.10 HSPF – can save you hundreds of dollars a year,
compared to a standard heat pump and air conditioner.
Quiet
and efficient operation
- Scroll
Compressor – provides smooth, efficient and quiet operation.
- High-Efficiency Outdoor Coil – provides exceptional heat transfer and low air resistance for
high-efficiency operation.
- Quiet,
Direct-Drive Fan – precision-balanced, direct-drive fan is designed to run slower for an enhanced level of quiet operation.
Easy installation and maintenance
- Brass Service Valves – isolate the
refrigeration system in outdoor units and allow for simple access.
- Full-Perimeter Base Rails – provide structural integrity during unit transport and movement.
Forklift slots and lifting holes help speed up tasks such as moving and lifting the unit when on the job site.
- Control Box – slide-out control box
with hinged panel access makes this a convenient and time-saving feature during installation and maintenance (15- and 20-ton
AC models only).
Reliable performance
- Fan Guard – heavy-duty guard increases
safety.
- Fan Motor – features
a fully enclosed design with a rain shield to provide maximum protection from weather, dust, corrosion and moisture.
- Corrosion-Resistant Cabinet – G-90
galvanized steel under a two-layer painted surface protects against rust and corrosion.
- High-Pressure Switch – extends the life of the unit by providing
a safeguard against excessive pressure.
- Loss-of-Charge
Switch – protects compressor from damage due to low refrigerant charge conditions.
- Crankcase Heaters – protect the compressor against refrigerant
migration that can occur during low ambient operations.
- Multiple Refrigeration Circuits – separate refrigeration circuits and scroll compressors provide
help to ensure against the loss of a compressor or refrigeration circuit for continued operation and cooling capability.
- Solid-State Defrost Control –
monitors the condition of the coil. Quickly and efficiently clears the build-up of frost on the coil.
- Minimum Run Time Control – prevents compressor short-cycling
and helps assure oil return to the compressor.
- Enhanced Coil Guard – protects the condenser coil, maintaining the efficiency of the unit. Heavy-gauge
steel construction and non-corrosive PVC coating assure long-lasing coil protection.
- High-Capacity Liquid Line Drier – protects the refrigeration system from moisture and dirt
(available on heat pump units only).
- Low
Ambient Operation – standard low ambient operation to 0ºF increases unit operating range to cover a wide range
of operating scenarios throughout the year.
Warranty
- 5-Year Limited Warranty on compressor.
- 1-Year Limited Warranty on covered
components.
HS/HP29 3- TO
5-TON
Features and Benefits
Improved reliability
- Compressor Low Ambient Cutoff – prevents
compressor operation when outdoor temperature is below 35°F.
- Compressor Time-off Control – improves compressor reliability by preventing short-cycling and
allowing the compressor to start in an unloaded condition.
- Loss-of-Charge Kit – protects compressor from damage due to low refrigerant charge conditions.
- High-Pressure Switch Kit –
protects the system from high-pressure conditions that can result from a fan failure or a blocked or dirty coil.
- Hail Guards – constructed of louvered
heavy-gauge steel, hail guards surround unit on all four sides and prevent damage to the coil.
- Freezestat – prevents system failure in cold conditions by
cycling the compressor off when the suction line temperature falls below the setpoint.
- Crankcase Heater – protects the compressor against refrigerant migration that can occur during
low ambient temperatures.
Application
solutions
- Low Ambient Control
to 30°F – allows for unit operation down to 30°F.
Quiet and efficient operation
- Compressor Sound Cover – reinforced vinyl cover with fiberglass insulation helps lower operating
sound levels.
- Mild Weather Kits
– allow heat pump units to operate in conditions up to 75ºF (heat pump units only)
Easy installation and maintenance
- Mounting Base – extremely durable, high-density polyethylene structural material is lightweight,
sturdy and provides a permanent foundation for outdoor units.
- Unit Stand-Off Kit – raises unit off the mounting surface and away from potentially damaging
moisture.
- Refrigerant Line Kits
– refrigerant lines are shipped cleaned, dried, pressurized and sealed at the factory for easy installation.
