Drain pipe! CautionIn order to drain water normally, the drain pipe shall be processed as specified inthe installation manual and shall be thermal insulated to avoid dew generation.Improper hose connection may cause indoor water leakage.RequirementsThe indoor drain pipe shall be thermal insulated.The connection part between the drain pipe and the indoor unit shall be insulated so as toprevent dew generation.The drain pipe shall be slant downwards (greater than 1/100). The middle part shall not beof 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, suppo-rts shall be provided every 1.5 ñ 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.Pipe and insulation materialRigid PVC pipe VP31.5mm (internal diameter)Foamed PE with thickness above 7mmPipeInsulationHoseDrain pipe size: ÿ 19.05mm 2 (3/4") PVC pipeThe 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 partsulation treatment:Wrap the hose and its clamp until to theindoor unit without any clearance withinsulating material, as shown in the figure.Drain confirmationDuring trial run, check that there is no leakage at the pipe connection part during waterdraining even in winter.Hose Hose clampSubsidiary insulation InsulationRigid PVC pipeWallOutsideSlantDrain pipe (suppliedby the user)VP30To the largest (app. 10cm)Down slope above 1/100S type elbow1.5m~2m SupportInsulation(supplied by the user)Down slopeabove 1/10029Installation Procedure
