point.
•
Level the plate horizontally and mark the holes to be
made on the wall for the installation using the screws
and rawplugs.
•
Remove the plate.
Warning!
Danger of breaks in the domestic installation.
Check that there are no electricity lines, pipes or
any other element which could be
impaired behind the spots where the holes are to
be drilled. If so, choose another installation
location and repeat the aforementioned steps..
•
Make the holes using a drill and insert the rawplugs.
•
Place the assembly plate in the assembly location,
level it horizontally and fix it with the screws and the
rawplugs.

Installation of the Pipes
9.3.1
Methods for the Correct Discharge of the
Condensed Water
Warning!
Danger of breakdowns or malfunction. Danger of
condensed water spillage. In order to ensure that
the unit drains correctly take the requirements
described in this section into account.
Methods for the removal of the condensed water which
is generated in the indoor unit:
-
Condensed water can be allowed to drain naturall
using the natural tilt of the condensed water pipe
along with the coolant pipe. In order for it to
be aesthetically pleasing, use a joint channel.
-
The natural tilt of the condensed water pipe from the
indoor unit to the container (washbasin, sink,
etc.). Different invisible installation solutions also exist.
-
Using an external pump for condensed water,
carrying the condensed water to the outside or to the
house drainage system.
-
By natural tilt to the collector deposit for
condensed water which is emptied using a pump for
condensed water. The pump for condensed water
receives a signal from the tank and takes the water
from the tank conveying it to the outside or to the
house drainage system.
Note!
This pump for condensed water is available as an
original Vaillant accessory with the
corresponding installation instructions.
Warning!
Danger of breakdowns or malfunction. Danger of
condensed water spillage. To ensure that the unit
carries out the drainage properly in the event of
draining using a natural tilt, the condensed water
pipe must also have a tilt from the indoor unit.

9.3.2 Handling the Coolant Pipes
Danger!
Danger of burns and eye injuries. In the event of
soldering, use suitable protection equipment
(protective soldering mask, soldering gloves,
solderer clothing).
Warning!
Danger of breakdowns or malfunction. Danger of
wear in the coolant pipes. To ensure that the
coolant pipes do not wear take the following
points into consideration:
-
Use pipes specifically intended for cooling.
Note!
In specialised dealers you will find coolant pipes
which are thermally insulated as a
Vaillant accessory.
- Ensure that the pipes are clean, dry and polished on
the inside.
- The insulation of the pipes should be done using
specific insulation for cooling.
- Observe the minimum and maximum pipe distances
for each model.
- Do not bend the pipes where possible. When bending
them, keep the radius as wide as possible to minimise
load losses.
- If soldering, do so using strong welding (copper-silver
alloy). During the soldering process a stream of dry
nitrogen should be run through the inside of the pipes
in order to avoid rusting.
- Only cut the coolant pipes using pipe cutters and
always keep the pipe ends covered.
- Any flaring work should be performed meticulously in
order to avoid subsequent losses of gas through the
pipes.
- When reviving keep the pipe opening directed
downwards in order to prevent shavings from getting
into the pipes.
- Mount the joining tubes carefully, ensuring they
cannot become displaced. Ensure that they will not
cause traction in the joins.
- Equip the coolant pipes (inflow and outflow) separately
and with thick diffusion heat insulation.
- Carefully squeeze the flaring connector, centring the
flaring cone and the flanged nut. Applying excessive
force without correctly centring can damage the
thread and cause a reduction in the water tightness in
the join.
9.3.3
Handling the Condensed Water Pipe
Warning!
Danger of breakdowns or malfunction. Danger of
incorrect drainage of the condensed water and
wear of materials due to dripping water. Take the
following points into consideration:
- Ensure that air circulates through the condensed
water pipe in order to guarantee that the water can be
freely released. Otherwise, the condensed water could
leak through the indoor unit body.
- Mount the pipe without bending it in order to avoid
blockage.
- If the water pipe is channelled outdoors, ensure that it
is insulated against freezing.
- If the condensed water pipe is installed in a room, fit
thermal insulation.
- Avoid installing the condensed water pipe with an
ascending bend (see Figure 9.1).
