R-22 systems. Do not use R-22 service equipment or components on
Puron equipment. Ensure service equipment is rated for Puron®.
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

distributor for better interpretation of the warnings.
General information
The Evolution Extreme 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 Evolution Extreme
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 Evolution wall control.
