9.3 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 naturally

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.
