6.3 Hydraulic connections
Caution
Before making the hydraulic connections, it is essential to flush
the domestic hot water circuits.
If flushing has to be done using an aggressive product,
neutralise the rinsing water before disposing of it in the waste
water network.
Note
The use of hoses which are too short or too rigid encourages
the transmission of vibrations and the occurrence of noises.

1
Connect the incoming cold water pipe to the drinking water connection.
2
Connect the outgoing domestic hot water pipe to the domestic hot
water connection.
Caution
Do not connect the domestic hot water connection directly to
copper pipes in order to prevent galvanic couplings in iron/
copper (risk of corrosion). It is compulsory to fit the domestic hot
water connection with a dielectric connection.
6.3.2 Connecting the condensate discharge pipe
1
Insert the condensate collector hose, Ø 9 mm, into the discharge
opening.
Caution
- Do not block the condensate discharge pipe.
- Connect the condensate discharge pipe in accordance with
prevailing local standards.
