Drain piping

1) Use commercial rigid polyvinyl chloride pipe (general VP 20 pipe, outer diameter 26mm, inner diameter 20mm) for the drain pipe.
2) The drain hose (outer diameter 18mm at connecting end, 220mm long) is supplied with the indoor unit. Prepare the drain
pipe picture below position.
3) The drain pipe should be inclined downward so that water will flow smoothly without any accumulation. (Should not be trap.)
4) Insert the drain hose to this depth so it won't be pulled out of the drain pipe.
5) Insulate the indoor drain pipe with 10mm or more of insulation material to prevent condensation.
6) Remove the air filters and pour some water into the drain pan to check the water flows smoothly.
