Installation Manual For Indoor Unit ! Caution In order to drain water normally, the drain pipe shall be processed as specified in the installation manual and shall be thermal insulated to avoid dew generation. Improper hose connection may cause indoor water leakage. Requirements The indoor drain pipe shall be thermal insulated. The connection part between the drain pipe and the indoor unit shall be insulated so as to prevent dew generation. The drain pipe shall be slant downwards (greater than 1/100). The middle part shall not be of S type elbow, otherwise abnormal sound will be produced. The horizontal length of the drain pipe shall be less than 20 m. In case of long pipe, supports shall be provided every 1.5 – 2m to prevent wavy form. Central piping shall be laid out according to the following figure. Take care not to apply external force onto the drain pipe connection part. 1.5m~2m Support Insulation Down slope (supplied by the user) above 1/100 S type elbow To the largest (app. 10cm) VP30 Down slope above 1/100 Pipe and insulation material Pipe Rigid PVC pipe VP20 mm (internal diameter) Insulation Foamed PE with thickness above 7 mm Wall Outside Slant Drain pipe (supplied by the user) Hose Drain pipe size: (3/4") PVC pipe The hose is used for adjusting the off-center and angle of the rigid PVC pipe. Directly stretch the hose to install without making any deformation. The soft end of the hose must be fastened with a hose clamp. Please apply the hose on horizontal part Hose Insulation treatment: Wrap the hose and its clamp until to the indoor unit without any clearance with insulating material, as shown in the figure.
