CAUTION
Initial commissioning must be done by a qualified
professional.
1. Flush the domestic circuit and fill the calorifer through the cold
water inlet tube.
2. Open a hot water tap.
3. Completely fill the domestic hot water calorifer via the cold water
inlet pipe, leaving the hot water valve open.
4. Close the hot water valve when the water flow is regular, without
noise in the pipes.
5. Carefully vent all of the DHW pipes by repeating steps 2 to 4 for
each hot water tap.
Venting the domestic hot water calorifer and the mains
network helps to prevent noises and banging caused by
trapped air moving through the pipes during draw-off.
6. Vent the tank exchanger circuit using the bleed valve provided for
this purpose.
7. Check the safety devices (particularly the valve or safety unit),
referring to the instructions provided with these components.
CAUTION
During the heating process, a certain amount of water may
flow through the valve or safety unit, this is caused by
water expansion. This phenomenon is completely normal
and must in no event be hindered.
4.11.1.
Drinking water quality
In regions where the water is very hard (TH > 20 °f), we recommend
fitting a softener.
The hardness of the water must always be between 12 °f and 20 °f to
be capable of providing effective protection against corrosion.
The softener does not bring about derogation of our warranty,
provided that the softener is:
- approved and set in accordance with the codes of practice and the
recommendations given in the instruction manual for the softener
- regularly inspected
- regularly serviced
