Designed for permanent installation, the tankless IW25-4 fixed dehumidifier can be mounted in the wall between existing studs or on virtually any hard wall surface including masonry and CMU block
How many square feet is the area?
The IW25-4 is effective in spaces up to 1,500 square feet.
Is floor-plan open/closed; for optimal flow of air?
An open floor plan is ideal for optimal operation to allow the free flow of treated air; doors in any closed spaces should remain open for adequate humidity removal.
Is the dehumidifier system able to be installed without blocking air-vent?
The permanent dehumidifier cannot block air vents but the ideal location is near an HVAC air return for efficient distribution of treated air.
Will the location of IW25 dehumidifier be aesthetically pleasing?
The sleek design of the IW25 works with any décor, and the wall mount allows it to be off the floor and tucked out of the way.
What type of draining system will be used, gravity flow or condensate pump?
If gravity draining is not optimal, the condensate pump will help move moisture 10′ vertically and 15′ horizontally without gravity drop.
Will water drain properly without blockage or kinks?
Moisture must be able to drain through the 8′ hose without any kinks or blockage; the hose can be easily trimmed to the length needed.
Is a power source accessible to dehumidifier?
The IW25-4 comes with an 8′ 120V plug-in electrical cord; a polarized 3-prong plug extension cord may be used if needed, or the unit can be hardwired into an existing electrical system.
Will standard 120V plug be used or will unit be hardwired?
Flexible installation options of the dehumidifier allow it to use either a standard 120V plug or hardwired into existing electrical system.
If choosing an On Wall mount, what type of material is the wall?
The IW25-4 can easily mount on virtually any hard surface, including wood, cement, brick, tile or masonry. Purchase mounting materials that best suit your wall fabrication.
If choosing an In Wall mount, what is the depth of wall and are there any space limitations?
The IW25-4 mounts between two studs at 16″ on center. It fully recesses in 2″ x 6″ walls and partially in 2″ x 4″ walls. It comes with a paintable, finished back side if visibility is needed, and a 2.2″ Exterior Sleeve* is available for a clean front bump-out look.
