1.3 Installing the internal unit
1. Push the piping, together with all cables, through the hole
made in the wall and hook the internal unit onto the top of
the template.
2. Shape the piping and cables well.
3. Push the lower part of the internal unit well up against the
template.
Make sure that:
a. The top and bottom hooks on the internal unit are securely
fastened onto the template.
b. The unit is fully horizontal.
If the appliance is not level, water may leak from it onto the
fl oor.
c. The drain pipe is at the right gradient (minimum of 3 cm
for each metre in length).
d. The drain pipe stays at the bottom of the hole in the wall.
NOTES:
- Do not kink or constrict the piping of the internal unit in any way.
Avoid bends measuring less than 10 cm in radius.
- Do not bend the same section of the pipe too often as it
could kink after 3 attempts.
- Remove the closing plugs from the internal unit piping
only immediately before you make the connections.
- Keep the condensation drain pipe at the bottom of the hole
in the wall, otherwise it could leak.
N.B. Pierce a hole in the wall that is 5-10 mm lower on the
outside than it is on the inside so that the slope encourages
the downfl ow of the condensation.
1.4 Installing the external unit
Keep to the procedure described herein, and then start mak-
ing the connections of the piping and electrical wiring:
- Install the external unit in a place where the noise made by
the appliance and the outlet of hot air cannot be a source
of inconvenience. Choose a place that does not obstruct
the free passage and where the condensation water pro-
duced can easily be ducted to the outside.
Do not install the external unit in narrow places which
limit the air fl ow or in places exposed to strong winds.
In case of wall installation;
- install the unit securely onto a solid wall.
- pinpoint the most suitable position on the wall, allowing
enough room for any maintenance operations to be car-
ried out easily;
- fasten the brackets to the wall using rawlplugs suitable for
the type of wall in question (take care not to damage any
wiring or piping in conduits);
- use more rawlplugs than the appliance weight would re-
quire: during operation, the appliance vibrates and will
have to remain installed for years without the screws ever
becoming loose.
