6Ultra-Aire 100V Installation Instructions www.Ultra-Aire.com | 1-800-533-7533
Important Precautions
• The device is designed to be installed indoors in a space that is protected from rain and flooding.
• Install the unit with enough space to access the front panel for maintenance and service.
• Avoid directing the discharge air at people. The dehumidifier should be used in the upright position.
• If used near a water source; be certain there is no chance the unit could fall into the water or get splashed and
that it is plugged into a dedicated circuit and Ground Fault Circuit Interrupter (GFCI) protected outlet.
• DO NOT use the dehumidifier as a bench or table.
• DO NOT place the dehumidifier directly on structural building members without vibration absorbers or unwanted
noise may result. Place the Ultra-Aire 100V on supports to raise the base of the unit.
• A drain pan MUST be placed under the dehumidifier if installed above a living area or above an area where
water leakage could cause damage.
Location Considerations
• Allow sufficient clearance to handle the unit’s overall dimensions as well as the necessary return and supply
ductwork to the unit.
• Allow sufficient clearance for filter removal and to prevent airflow obstruction.
• Electrical service access will require the removal of a side panel. Allow sufficient clearance on a side of the unit.
• Locate the dehumidifier in an area where the cord’s length (9') easily reaches a 115 VAC electrical outlet with a
minimum of a 15 Amp circuit capacity.
• Locate the dehumidifier in an area where field wiring the control (low voltage) to the unit will be possible.
• It is recommended that a backdraft damper be used in the discharge duct of the Ultra-Aire 100V, especially
when connecting to the supply ducting system. The backdraft damper prevents supply air from counter
flowing through the Ultra-Aire 100V
when it is not operating. The
dehumidifier’s location should be
chosen to allow installation of this
accessory if necessary.
• DO NOT hang the Ultra-Aire 100V
from its cabinet.
• Allow for proper routing and
drainage of needed drain pipes.

8Ultra-Aire 100V Installation Instructions www.Ultra-Aire.com | 1-800-533-7533
The Ultra-Aire 100V plugs into a common grounded 115 VAC outlet. The device draws 5.9 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 100V. 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 100V 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 100V 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 100V and the control are numbered and color-coded to
prevent confusion.
• Be sure to consult the
electrical schematic in the
CONTROLS Section
(page 19) of this manual or
inside the access panel of
the Ultra-Aire 100V
before making control
connections.
WARNING!
THE REMOTE CONTROLS OF THE ULTRA-AIRE 100V 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 CONTROL WIRES LEAVING THE ULTRA-AIRE 100V MAY NOT BE USED WITH
CERTAIN CONTROLS AND SHOULD BE LEFT UNCONNECTED WITH WIRE NUTS TAPED ONTO
THE STRIPPED ENDS FOR SAFETY.

www.Ultra-Aire.com | 1-800-533-7533 Ultra-Aire 100V Installation Instructions
The Ultra-Aire 100V generates condensate.
Place a secondary drain pan under the dehumidifier if it is suspended above a finished area or above an
area where water leakage could cause damage.
Condensate drains by gravity via the clear hose extending from the unit. Route the hose to a floor drain. Use
care to keep the hose as flat to the floor as possible; excessive humps will prevent proper drainage. We do
not call for a trap since there is an internal trap with this unit. If the Ultra-Aire 100V is located too far from a
floor drain for the attached hose to reach, inexpensive 1⁄2” PVC pipe can be used to extend it. It is commonly
available in 10’ lengths from building supply, plumbing and hardware stores. It will slide tightly inside the end
of the drain hose. If more than one length of pipe is required, they can be joined with a short piece cut from the
end of the drain hose.
An optional condensate pump kit is available for use with the Ultra-Aire 100V and may be installed if lift is
required to dispose of condensate. Condensate is automatically pumped to a remote location when the
water level in the pump’s reservoir rises to close the float switch.
The pump also contains a safety float
switch. The white leads from this
switch extend from beneath the pump
cover. This switch should be installed
in series with the field wire that
connects to the common lead from
the Ultra-Aire 100V to the control panel.
If the pump fails, this switch opens
the common control circuit and stops
water production before the reservoir
overflows. Contact a qualified electrician
to install the safety float switch to the
Ultra-Aire 100V dehumidifier.
Note: An optional condensate pump
kit can be purchased through your
dealer or online.

10 Ultra-Aire 100V Installation Instructions www.Ultra-Aire.com | 1-800-533-7533
The recommended installation creates a separate return for the Ultra-Aire 100V in a central area of the
structure. Duct the supply of the unit to the air supply of the existing HVAC system. Connect an insulated
duct from outside to the 6" collar of the Ultra-Aire 100V to provide fresh make-up air.
DUCTING TO HVAC SYSTEMS
CAUTION!
DO NOT CONNECT WITH A STATIC PRESSURE GREATER THAN OR EQUAL TO +0.5 WG.
CONTACT TECHNICAL SUPPORT AT 1-800-533-7533 FOR ADDITIONAL DETAILS.
Ducting Considerations:
• All flexible ducting connected to the Ultra-Aire 100V should be UL listed.
• A short piece of flexible ducting on all Ultra-Aire 100V duct connections is recommended to reduce noise
and vibration transmitted to rigid ductwork in the structure.
• Use a minimum 8" diameter round or equivalent rectangular duct for total duct lengths of up to 25'. Use a
minimum 10" diameter round or equivalent rectangular duct for longer lengths.
• Grills or diffusers on the duct ends must not excessively restrict airflow.
• A length of 10" or more of insulated flex duct or any other vibration isolating material on the outlet of the
Ultra-Aire 100V will reduce air noise from the blower.
• Effective dehumidification may require that ducting be branched to isolated, stagnant air flow areas.
When ducting to two or three areas, use 8" or larger diameter branch ducting. When ducting to four or
more areas, use 6" or larger diameter branch ducting. Provisions must be made to provide airflow from
supply locations to the central return location. Proper air distribution is important to ensure even humidity
control and heat distribution throughout the structure.
• DO NOT locate the return in a bathroom or a kitchen.
