1.  Intended Application for Quest 150 Dual

The Quest 150 Dual is intended for use in light commercial structures: however, the unit can be placed in almost any 

setting where dehumidification is desired. Use in highly corrosive applications and pool areas may void warranty.
The Quest 150 Dual 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 Quest 150 Dual, water intrusion and air 

infiltration problems should be addressed.

 

2. Registrations

The Quest 150 Dual units conforms to unified standard UL 60335-2-40 and CSA standard C22.2.60335-2-40.
