The Ultra Aire Dehumidifier plugs into a common grounded 115 VAC outlet. Locate the dehumidifier in an
area where the cord’s length (9') easily reaches a 115 VAC electrical outlet with a minimum of 15 Amp circuit
capacity. If used in an area that may become wet, a GFCI protected circuit is recommended. Consult local
electrical codes for further information.
Ultra Aire offers a variety of control devices for use with the Ultra Aire Dehumidifier. The control is to be located
remotely from the dehumidifier and placed in the space to be conditioned. A low voltage (24 Volt) control MUST be
used with the Ultra Aire Dehumidifier and MUST be connected with low voltage (18-22 gauge) thermostat wire.
