GENERAL INFORMATION Dryer Safety Dryer Safety Your safety and the safety of others are very important. We have provided many important safety messages in this manual and on your appliance. Always read and obey all safety messages. This is the safety alert symbol. This symbol alerts you to potential hazards that can kill or hurt you and others. -
Page 7: General Theory Of Operation
Heating System - instead of two electric heaters, the HybridCare™ dryer substitutes the compressor (sealed system) for one of the heaters. The Compressor and Heater act very similarly as the two heaters did in the Whirlpool direct drive dryer. Previously, each heater was connected to its own heater relay. - Page 8 The HybridCare™ Dryer is not unlike its predecessor—the Whirlpool Duet direct-drive dryer (aka Alpha). Most of the components used in the Whirlpool direct drive dryer are also used in the new HybridCare™ dryer. Think of the compressor as the second heater.
