Dehumidifier can go in the mechanical room. We would need a box and half of 10 inch flex and one splice collar to run the duct up into the encapsulated crawlspace. We would need about 15 feet of 14 gauge Romax wire GFI box and cover. Eaton 15a breaker single pole. The drain would drain into the floor drain next to where the units going to be. There are no crawlspace vents. About three hours to install. They also want a price to add an Iwave to their Bosch system
