DRAIN INSTALLATION The drain outlet on the dehumidifier can be hard piped using a 3/4" PVC Slip x 3/4” MNPT fitting and 3/4" nominal drain tubing or the provided 3/4” MNPT x 3/4" hose barb fitting and 3/4" clear PVC tubing can be used to drain the dehumidifier. Always maintain a constant downward slope from the dehumidifier to the drain and do not allow soft tubing to curl up which may result in air lock. Note: PTFE thread seal tape is recommended for the threaded connection and hand tighten only.
PAGE 10
DUCTING TO HVAC SYSTEM – BASEMENT AND ATTIC INSTALLATIONS The Preferred Installation is to duct the dehumidifier to pull air from and return dehumidified air to the HVAC return duct. This installation will ensure warm, dehumidified air is thoroughly mixed with the HVAC system air before being discharged into the living space. Alternatively, the dehumidifier can be ducted to discharge to the supply duct, but the external static pressure of the HVAC system must not exceed 0.6” w.c.
PAGE 11
DUCTING FOR STAND ALONE INSTALLATIONS OR NON-DUCTED INSTALLATIONS In this installation the dehumidifier is not ducted to the HVAC system and is used to dehumidify a specific area. This installation is typically in basements or crawl spaces.
PAGE 12
DUCTING FOR TWO ZONE INSTALLATIONS Note: Dehumidifier zoning is not recommended in HVAC zoning applications. In this installation the dehumidifier controls the humidity in two separate zones, a Primary and Secondary Zone. The dehumidifier will dehumidify the Primary Zone as the first priority, and will switch to the Secondary Zone after the dehumidification needs of the Primary Zone have been satisfied.
