8. DUCTING GUIDELINES
CAUTION! Quest 506 is intended for use in statics under .25”WG.
• Ducting either the intake or exhaust use a minimum of two 12” diameter round ducts minimum.
• Grills or diffusers on the duct ends must not excessively restrict airflow.
• Effective dehumidification may require ducting to be branched to isolated or stagnant flow areas.
Be sure to use appropriate size duct branches to maintain proper feed throughout the ducting
system.
• System control should be placed remotely from the dehumidifier in a central location.
• Intake and exhaust ducting should have a minimum of 4 feet from the unit before any turns.
CAUTION! Do not connect with a static pressure greater than +.25”wg.
Contact technical support for additional details.
• Optional duct kits are available from the factory: Exhaust Kit 4038641 and Intake Kit 4038642.
See figures below for plenum dimensions and duct diameters. Alternatively, licensed contractors
can fabricate duct plenums and reference figures below for safe fastener mounting points.
