4 Operation

The Ultra-Aire UA-135H Air Purifying Dehumidifier performs three functions in one compact enclosure; High-Capacity Dehumidification, Fresh Air Ventilation, and Filtration. The UA-135H can be equipped with various accessories to enhance its operation. A remote control panel must be used with the UA-135H. Your unit has one of three remote control panels. To determine how each control operates the UA-135H it must first be determined which control is being used and whether or not the 135H is ducted for fresh air ventilation. Refer to Section 7 to identify which control you have installed. Inspect ducting or contact your installer to determine if your UA-135H is ducted for outside air.
