Page 8: Electrical Requirements
ELECTRICAL REQUIREMENTS The Ultra-Aire XT155H plugs into a common grounded 115 VAC outlet. The device draws 8.0 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. -
Page 9: Drain Installation
DRAIN INSTALLATION The Ultra-Aire XT155H 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. A drain trap is required for the dehumidifier to drain properly. Install a 3/4" threaded male NPT adapter to the drain pan. -

Page 15: Fresh Air Ventilation
FRESH AIR VENTILATION Fresh air ventilation is optional. Fresh air may be brought into the structure by connecting an insulated duct from outside the structure to the 6" inlet of the Ultra-Aire XT155H. A ventilation control is needed to program the time and frequency that the unit introduces outside air. -
Page 16: Determine Ventilation Requirements
FRESH AIR VENTILATION Determine Ventilation Requirements The MINIMUM ventilation requirement is calculated using ASHRAE 62.2-2010. Use one or both of the options below to determine your ventilation requirement. Follow all local and national building and safety codes. Option 1: Calculating Airflow Requirement Using ASHRAE 62.2-2010 Airflow Equation ASHRAE Airflow in CFM = [House Area in Sq.Ft. -

Page 19: Air Filtration
AIR FILTRATION The Ultra-Aire XT155H is equipped with a MERV-11 filter. An optional MERV-14 filter and filter housing is available at www.UltraAireFilters.com. The filter should be checked and replaced every three to six months. Operating the unit with a dirty filter will reduce dehumidifier capacity and efficiency. DO NOT operate the unit without the recommended filter. -
