1. Intended Application(s)

The Santa Fe Impact is intended for use in crawlspaces or 
basements: however, the unit can be placed in almost any 
residential setting where dehumidification is desired. Use 
in non-residential applications and pool areas may void 
warranty.

The Santa Fe Impact is designed to operate in temperatures 
between 56° and 95°F. 

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 Impact, water intrusion and air 
infiltration problems should be addressed.

2. Registrations

The Santa Fe Impact conforms to UL STD 474.
