(Use an airfilter 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 tapeor something similar to prevent air escaping.Caution• Be sure to insulate the duct to prevent condensation from forming. (Material:glass wool or polyethylene foam, 25mm thick)• Use electric insulation between the duct and the wall when using metal ductsto pass metal laths of the net or fence shape or metal plating into woodenbuildings.WIRINGSee the installation manual supplied with the outdoor unit. HOW TO CONNECT WIRINGS• Wire only after removing thecontrol box lid as shown in thefigure.Caution• When clamping the wiring, usethe included clamping material asshown in the figure to preventoutside pressure being exertedon the wiring connections andclamp firmly.• When doing the wiring, makesure the wiring is neat and doesnot cause the control box lid tostick up, then close the coverfirmly.
