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.
