Immediately call a qualified service technician to inspect the unit and to replace any part of the control system which has been under water. Defrost Mode When your unit is providing heat to your home or office and the outdoor temperature drops below 45°F, moisture may begin to freeze on the surface of the coil. If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat absorbed from the outside air. So, to maintain energy-efficient operation, your unit has an automatic defrost mode. The defrost mode starts at a preset time interval of 30 minutes, although, it may be reset to 60, 90 or 120 minutes. Defrost will start at the preset time only if the ice is sufficient heating operation. to interfere After the ice is melted from the coil. or after a maximum ELECTRICAL SHOCK utes in defrost mode, the unit automatically heating operation.
