IMPORTANT

1. This product has been designed and manufactured to meet ENERGY STAR® criteria for energy efﬁ ciency when matched with appropriate coil components. However, proper refrigerant charge and proper air ﬂ ow are critical to achieve rated capacity and efﬁ ciency. Installation of this product should follow the manufacturer’s refrigerant charging and air ﬂ ow instructions.

Failure to conﬁ rm proper charge and airﬂ ow may reduce energy efﬁ ciency and shorten equipment life.

2. This model is equipped with Room Freeze Protection (RFP) feature. Room Freeze Protection function (RFP) is used in spaces that are unoccupied during the winter, for the purpose of protecting any equipment or appliances which may be destroyed as a result of freezing temperature. When the RFP is selected, the unit will operate the fan at high speed for proper room temperature monitoring. When the sensor detects that the room temperature has dropped below 46°F (8°C), the compressor/heat pump operation begins. When the room temperature reaches 50°F (10°C), the unit shuts off, then will repeat continuously if the temperature drops below 46°F (8°C) again. The Room Freeze Protection function (RFP) cannot be used unless the unit is energized and set into the RFP mode. In the advent of a power failure this mode will not function. During the RFP mode, POWERFUL OPERATION, QUIET OPERATION AND FAN SPEED selection are all disabled. Please consult with your HVAC installer or professional for more details.
