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. -
Page 9: Drain Installation
Pitch of drain should be 1" per 10'. An optional condensate pump kit is available for use with the Ultra-Aire 120V 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. -
Page 10: Ducting To Hvac Systems
• All flexible ducting connected to the Ultra-Aire 120V should be UL listed. • A short piece of flexible ducting on all Ultra-Aire 120V duct connections is recommended to reduce noise and vibration transmitted to rigid ductwork in the structure. -

DUCTING TO HVAC SYSTEMS No Existing Ductwork Installation When installing the Ultra-Aire 120V in a structure that does not have a forced air HVAC system, a single return for the Ultra-Aire 120V should be installed in a central location. Install an insulated duct from outside to the 6" collar of the Ultra-Aire 120V to provide fresh air ventilation (optional). -
Page 15: Fresh Air Ventilation
• An insulated 6" diameter duct provides up to 100 CFM of outside air. • If the fresh air ventilation duct is to be used, the return of the Ultra-Aire 120V must be ducted or an inline fan may be required on the fresh air ventilation line to bring in outside air. -
