Installing The Duct - Daikin FDXS25CVMB Instruction Manual

INSTALLING THE DUCT

Connect the duct supplied in the field.
Air inlet side
• Attach the duct and intake-side flange (field supply).
• Connect the flange to the main unit with accessory screws (in 20 or 24 positions).
• Wrap the intake-side flange and duct connection area with aluminum tape or something similar to prevent air escaping.
Caution
When attaching a duct to the intake side, be sure also to attach an air filter inside the air passage on the intake side. (Use an air
filter whose dust collecting efficiency is at least 50% in a gravimetric technique.)
Outlet side
• Connect the duct according to the inside of the outlet-side flange.
• Wrap the outlet-side flange and the duct connection area with aluminum tape or something similar to prevent air escaping.
Caution
• Be sure to insulate the duct to prevent condensation from forming. (Material: glass wool or polyethylene foam, 25 mm thick)
• Use electric insulation between the duct and the wall when using metal ducts to pass metal laths of the net or fence shape or
metal plating into wooden buildings.
