Make sure the unit is level at all four corners using a levelor a water-filled vinyl tube.cbbaa Levelb Vinyl tubec Water levelNOTICEDo NOT install the unit tilted. Possible consequence: Ifthe unit is tilted against the direction of the condensate flow(the drain piping side is raised), the float switch mightmalfunction and cause water to drip.5.1.2 Guidelines when installing the drainpipingMake sure condensation water can be evacuated properly. Thisinvolves:▪ General guidelines▪ Connecting the drain piping to the indoor unit▪ Checking for water leaksGeneral guidelines▪ Pipe length. Keep drain piping as short as possible.▪ Pipe size. Keep the pipe size equal to or greater than that of theconnecting pipe (vinyl pipe of 25 mm nominal diameter and32 mm outer diameter).▪ Slope. Make sure the drain piping slopes down (at least 1/100) toprevent air from being trapped in the piping. Use hanging bars asshown.1~1.5 m aa Hanging barO AllowedX Not allowed▪ Rising piping. If necessary to make the slope possible, you caninstall rising piping.▪ Drain hose inclination: 0~75 mm to avoid stress on the pipingand to avoid air bubbles.▪ Rising piping: ≤300 mm from the unit, ≤675 mm perpendicularto the unit.≤675≤3000~751000~1500(mm)bab ca dda Metal clamp (accessory)b Drain hose (accessory)c Rising drain piping (vinyl pipe of 25 mm nominal diameterand 32 mm outer diameter) (field supply)d Hanging bars (field supply)▪ Condensation. Take measures against condensation. Insulatethe complete drain piping in the building.▪ Combining drain pipes. You can combine drain pipes. Makesure to use drain pipes and T-joints with a correct gauge for theoperating capacity of the units.≥100≤675(mm)aa T-joint
