When the machine is heating, it produces condensate
that has to be eliminated through a specific drain line,
otherwise the machine will not work. Drainage occurs by
gravity. For this reason, it is essential for the drain line to
have a minimum inclination of at least 3% throughout its
length. The pipe can be rigid or not, with a minimum
internal diameter of 16 mm.
If the line drains into a sewer system, it should be provided
with a trap ahead of the main outlet.
The trap should be at least 300 mm lower than the inlet
opening on the air conditioner (fig. 7).
If the drainpipe drains into a vessel (tank or other
container), this container should not be sealed and the
drainpipe should not remain immersed in the water (see
fig. 8).
The correct position for the pipe inlet on the machine is
shown on the template for drilling and positioning the
machine (see also fig. 6).
The air conditioner is equipped with a pipe with an external
diameter of 14 mm for drainage of condensate.
This pipe protrudes from the machine for a length of about
400 mm.
The pipe should be fitted inside the one provided by you
for a distance of at least 200 mm, without any sharp bends
that could obstruct it.
When draining toward the outside, the pipe can be
inserted through the wall (always making sure to give it a
suitable inclination) (see fig. 5).
Caution: make sure, in this case, that the water expelled
outward does not damage or disturb persons or
property. During the winter this type of drainage may
cause sheets of ice to form.
After drilling the holes, the plastic pipes supplied with the
air conditioner have to be fitted through them. The pipe
with insulation on the inside has to be fitted in the right-
hand hole with the insulated part toward the inside as
indicated on the label applied to it. The length of the pipes
should be 55 mm less than that of the wall. To cut the
pipe, a normal handsaw can be used. After cutting the
pipes, fit the ends into the two internal anchoring flanges
(fig. 10).
The tube diameter is nearly the same as those carried
out using the 152/154 mm nominal diameter core drill. In
order to introduce the tubes, they must therefore be forced
slightly using, in the most difficult cases, a normal rubber
hammer (fig. 10/1). Having the hole internal diameter
extremely similar to the tube external diameter avoids
dangerous slacks which may generate humidity
infiltrations or air noises. Should the insertion prove to be
too difficult, we suggest you drill using the core bit inside
the hole so as to widen the internal diameter slightly.
Next, fit the pipes into the holes in the wall and fasten the
flanges with 4 anchor bolts with diameter 6, taking care
to keep the two fastening holes in a horizontal position.
