Ultra-Aire XT205H Installation Instructions
The Ultra-Aire XT205H plugs into a common grounded 115 VAC outlet. The device draws 13.2 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 20 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 XT205H. 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 XT205H and MUST be connected with low voltage (18-22 gauge) thermostat wire.

ELECTRICAL REQUIREMENTS
CAUTION!
DO NOT ALLOW THE YELLOW LEAD TO CONTACT THE RED OR WHITE LEAD ON THE
ULTRA-AIRE XT205H 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 control wires leaving the Ultra-Aire XT205H
and the control are numbered and color-coded to
prevent confusion.
• Be sure to consult the electrical schematic in the
CONTROLS Section (page 20) of this manual or
inside the access panel of the Ultra-Aire XT205H
before making control connections.
WARNING!
THE REMOTE CONTROLS OF THE ULTRA-AIRE XT205H ARE POWERED BY A LOW VOLTAGE CIR-
CUIT (24 VAC) AND MUST NEVER CONTACT OR BE CONNECTED TO A HIGH VOLTAGE CIRCUIT.
CAUTION!
SOME OF THE CONTROL WIRES LEAVING THE ULTRA-AIRE XT205H MAY NOT BE USED WITH
CERTAIN CONTROLS AND SHOULD BE LEFT UNCONNECTED WITH WIRE NUTS TAPED ONTO
THE STRIPPED ENDS FOR SAFETY.
