water supply pipe exceeds the maximum
working pressure of the tank, 8 bar. Refer to
the Technical details.
3. Install a non-return valve (5).
4. Install an expansion valve (15).
5. Connect the overflow connection of the
expansion valve, to an open waste water
pipe.
6. Install an expansion vessel (16).

n
Note
Insulate long hot water pipes to prevent
unnecessary energy loss.
Install the hot water connection:
1. Install a stop valve (11) in the hot water
outlet pipe for service reasons.
2. If applicable, install a temperature gauge
(12).
3. Install a T&P valve (3).

8.4.3 Circulation connection

Install a circulation system when an immediate
flow of hot water at draw-off points is required.
This improves comfort and reduces water
wastage.
