Ultra-Aire 120V Installation Instructions www.Ultra-Aire.com | (800) 533-7533
The Ultra-Aire 120V plugs into a common grounded 115 VAC outlet. The device draws 5.8 Amps at 80°F
and 60% RH. 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 120V. 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 120V and MUST be connected with low voltage (18-22 gauge) thermostat wire.
ELECTRICAL REQUIREMENTS
CAUTION!
DO NOT ALLOW THE 24V TERMINAL TO CONTACT THE COM TERMINAL ON THE ULTRA-AIRE
120V OR DAMAGE TO THE TRANSFORMER WILL RESULT.
Electrical Precautions
• Do not install the control where it may not accurately sense the relative humidity such as near HVAC
supply registers, near exterior doors, on an outside wall, near a window, or near a water source.
• The terminals on the Ultra-Aire 120V and the control are labeled to prevent confusion.
• Be sure to consult the electrical schematic in the CONTROLS Section (Page 17) of this manual or inside
the access panel of the Ultra-Aire 120V before making control connections.
WARNING!
THE REMOTE CONTROLS OF THE ULTRA-AIRE 120V ARE POWERED BY A LOW VOLTAGE CIRCUIT
(24 VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
CAUTION!
SOME OF THE TERMINALS ON THE ULTRA-AIRE 120V MAY NOT BE USED WITH CERTAIN
CONTROLS AND SHOULD BE LEFT UNCONNECTED.
