Page 4: Intended Applications
Intended Applications The Santa Fe Oasis105 is registered with the DOE as a portable dehumidifier with a capacity greater than 50 pints per day. It is a stand-alone dehumidifier intended to operate within the dehumidified space, such as basements: however, the unit can be placed in almost any residential setting where dehumidification is desired. The Santa Fe Oasis105 is designed to operate in temperatures between 49° and 95°F. This unit works most effectively between 56° and 95°. In order to efficiently control humidity levels, the area in which the dehumidifier is to be operated must be free of water intrusion or excessive fresh (outside) air infiltration. Before installing the Santa Fe Oasis105, water intrusion and air infiltration problems should be addressed. Registrations & Certifications The Santa Fe Oasis105 conforms to unified standard UL 60335-2-40 and CSA standard C22.2.60335-2-40. The Santa Fe Oasis105 is certified as a “Portable Dehumidifier” per 10CFR430 - Energy Conservation Program for Consumer Products Brand Name Individual Basic Model Rating... -
Page 5: Dehumidifier Set Up
Dehumidifier Set Up Location Considerations • L ocate the dehumidifier near a suitable drain (8' drain hose included). Allow for proper drainage and routing of needed drain pipes. • L ocate 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. • The unit is designed to operate while level. If the unit is placed on an unlevel surface, refer to section below (Installing Leveling Feet). Failure to level the unit may result in leakage or improper drainage. • T he unit should be suspended with a hang kit from the floor joists if there is any possibility of flooding. A flooded unit is not covered by warranty. Feet will be installed as a securing measure after the hang kit is put on the dehumidifier. DO NOT hang the dehumidifier from its’ cabinet. -

Page 9: Air Filtration
Air Filtration The Santa Fe Oasis105 dehumidifier is equipped with MERV-13 air filter (89-90% ASHRAE dust spot). The filters 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 a MERV-8, MERV-11 or MERV-13 filter. Filter non-compliance voids the product warranty. CAUTION! MAKE SURE UNIT IS OFF BEFORE CHANGING THE FILTER. FAILURE TO FOLLOW FILTER HANDLING INSTRUCTIONS MAY RESULT IN IMPROPER FUNCTION OF THE DEHUMIDIFIER AND CAUSE PREMATURE FILTER WEAR OR UNIT DAMAGE. Changing the Filter For greatest filtration and efficiency of the Santa Fe Oasis105 dehumidifier, it is recommended the air filters be replaced every three to six months. -
Page 10: Basement/Crawl Space Installation
Basement/Crawl Space Installation 1. The Oasis105 must operate in an enclosed area to be most effective. Close all exterior vents, doors, windows, and other outside openings to the space. The effectiveness of the dehumidifier depends on the rate at which new moisture-laden air enters the room. 2. Place dehumidifier in a central location that does not restrict the airflow of the air intake and air outlet. 3. The dehumidifier must be installed on a level floor to ensure water drains out of the unit correctly. 4. There should be a minimum of 14 inches clearance around the dehumidifier. The unit will produce heat while in operation and should not be operated in an enclosed small space like a closet unless it is ducted. The Oasis105 is designed to operate between 49 °F and 115 °F. -
