Installation Manua l Installing Mounting Plate 1.Make the mounting plate completely level . As the water tray's oulet of the indoor unit is two-way type, the indoor unit during installation should slightly slant to watert tray's outlet for smooth drainage of condensing water.
Instal lation Manua l Installing Indoor Unit The piping can be output from right, right rear , left or left rear . When routing the piping and wiring from the left or right side of indoor unit, cut off the tailings from the chassis as necessary(As shown in Fig.
Ø Condensate drainage of outdoor unit (not for cooling only) The condensate and defrosting water formd during heating in the outdoor unit can be properly discharged by drainage pipe .
Do not switch on power before installation is finished completely. Electric wiring must be connected correctly and securely. Cut-off valves of the connection pipes should be opened. Switch on power and press "ON/OFF" button on the wireless remote controller to start the operation.
