INSTALLATION BY A HVAC PROFESSIONAL IS RECOMMENDED
The Quest 185 Cool is a split system dehumidifier with sensible cooling
that is integrated into the heating and cooling system to provide the
ultimate in comfort, health and property protection through:
• Dehumidification
• Sensible Cooling
• Air Filtration
The two-piece design allows the sensible heat load generated from
dehumidifying the room to be released in the outside condensing unit,
thus eliminating the need for additional cooling and reducing air conditioner run time.
