2.3.2
Provision for draining condensate for machines with
heat pump.
When the machine is heating, it produces condensate that
has to be drained 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 a least 3% throughout its length.
The pipe can be rigid or not, with a minimum internal
diameter of 16mm.
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 300mm 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 be immersed in 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 14mm for drainage of condensate.
This pipe protrudes from the machine for a length of about
400mm.
The pipe should be fitted inside the one provided by you
for a distance of at least 300mm, without any sharp bends
that would 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 person or
property. During winter time this type of drainage may
cause sheets of ice to form.
2.3.3
Installation of air pipes and external gratings.
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 55mm less that that of the wall. To cut the pipe a
normal hacksaw can be used. After cutting the pipes fit the
ends into the two internal anchoring flanges (fig,10).
The tubes diameter is nearly the same as those carried out
using the 152mm nominal diameter core drill. In order to
introduce the tubes, they must therefore be forced slightly
using, in most difficult cases, a normal rubber hammer
(fig.10.1). Having the hole internal diameter extremely
similar to the tube external diameter avoids air gaps which
may generate humidity leaks or air noises. Should it prove
difficult to insert then widen the hole slightly using the
drill and core bit.
Next, fit the pipes into the holes in the wall and fasten the
flanges with 4 screws, diameter 6mm, taking care to keep
the two fastening holes in a horizontal position.
