▪ General guidelines

▪ Connecting the drain piping to the indoor unit

▪ Checking for water leaks

General guidelines

Pipe length.

 Keep drain piping as short as possible.

Pipe size.

 Keep the pipe size equal to or greater than that of the

connecting  pipe  (vinyl  pipe  of  25  mm  nominal  diameter  and
32 mm outer diameter).

Slope.

 Make sure the drain piping slopes down (at least 1/100) to

prevent air from being trapped in the piping. Use hanging bars as
shown.

1~1.5 m

Rising  piping

.  If  necessary  to  make  the  slope  possible,  you  can

install rising piping.

▪ Drain  hose  inclination:  0~75  mm  to  avoid  stress  on  the  piping

and to avoid air bubbles.

▪ Rising  piping:  ≤300  mm  from  the  unit,  ≤625  mm  perpendicular

to the unit.

Condensation.

  Take  measures  against  condensation.  Insulate

the complete drain piping in the building.

Combining  drain  pipes.

  You  can  combine  drain  pipes.  Make

sure to use drain pipes and T-joints with the correct gauge for the
operating capacity of the units.

NOTICE

▪ Do NOT remove the drain pipe plug. Water might leak

out.

▪ Use the drain outlet only to discharge the water before

maintenance.

▪ Insert  and  remove  the  drain  plug  gently.  Excessive

force may deform the drain socket of the drain pan.

Pull out the plug.

▪ Do NOT wiggle the plug up and down.

Push in the plug.

▪ Set the plug and push it in using a Phillips screwdriver.
