To drill a wall hole

CAUTION
For walls containing a metal frame or a metal board, use a
wall embedded pipe and wall cover in the feed-through
hole to prevent possible heat, electrical shock, or fire.
NOTICE
Be sure to seal the gaps around the pipes with sealing
material (field supply), in order to prevent water leakage.
1 Bore a 65 mm large feed-through hole in the wall with a
downward slope towards the outside.
2 Insert a wall embedded pipe into the hole.
3 Insert a wall cover into the wall pipe.

To provide drainage

Make sure condensation water can be evacuated properly. This
involves:
▪ 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. If drain hose extension or embedded drain piping is
required, use appropriate parts that match the hose front end.
NOTICE
▪ Install the drain hose with a downward slope.
▪ Traps are NOT permitted.
▪ Do NOT put the end of the hose in water.
▪ Drain hose extension. To extend the drain hose, use a field
supplied hose with inner Ø16 mm. Do NOT forget to use a heat
insulation tube on the indoor section of the extension hose.

c Extension drain hose
▪ Ridgid polyvinyl chloride pipe. When connecting a ridgid
polyvinyl chloride pipe (nominal Ø13 mm) directly to the drain
hose as with embedded piping work, use a field supplied drain
socket (nominal Ø13 mm).
