SAFETY CONSIDERATIONS
Installation, service, and repair of these units should be attempted only
by trained service technicians familiar with standard service instruction
and training material.
All equipment should be installed in accordance with accepted practices
and unit Installation Instructions, and in compliance with all national and
local codes. Power should be turned off when servicing or repairing
electrical components. Extreme caution should be observed when
troubleshooting electrical components with power on. Observe all
warning notices posted on equipment and in instructions or manuals.
Refrigeration systems contain refrigerant under pressure. Extreme
caution should be observed when handling refrigerants. Wear safety
glasses and gloves to prevent personal injury. During normal system
operations, some components are hot and can cause burns. Rotating fan
blades can cause personal injury. Appropriate safety considerations are
posted throughout this manual where potentially dangerous techniques
are addressed.
If you do not understand any of the warnings, contact your product
distributor for better interpretation of the warnings.
General information
The Greenspeed Intelligence heat pump and air conditioner features the
latest variable speed technology. The heart of the system is the Samsung
high side rotary or scroll variable speed compressor powered through the
use of the Samsung variable frequency drive (VFD) control. By
combining the Primary Control Module (PCM), an ECM outdoor fan,
Samsung VFD, Samsung variable speed compressor and the Infinity
Series outdoor cabinet, the HP unit achieves a Seasonal Energy
Efficiency Ratio (SEER) of up to 24 and up to 13 Heating Seasonal
Performance Factor (HSPF) and the AC achieves up to 26 SEER.
To ensure all of the above technology provides the ultimate in comfort, it
is combined with either a fan coil or Variable Speed Gas furnace
controlled with a two wire communication Infinity wall control.
