5. HYDRAULIC CONNECTION
Before proceeding with the hydraulic connection, the supply pipes must be thoroughly
cleaned to avoid introducing metal or other particles into the tank.
If metal pipes are used, the connection to the hot water outlet must use a dielectric pipe
joint or cast-iron sleeve to prevent galvanic corrosion (iron-copper). Brass connections
are prohibited here. A certified safety unit or non-return flap and safety valve assembly is
obligatory.
If the network supply pressure is ≥ 5 bar, a pressure reducer must be fitted to the distribution
outlet. A pressure of 3 to 4 bar is recommended. Check when hot that the pressure does not
exceed 6 bar.
.
Fit a bleed outlet to the tank´s top connection (DHW outlet).
To avoid clogging the installation´s components (heat exchangers, safety valve, safety unit)
with sludge, a filter must be fitted to the domestic cold water supply outlet feeding the tank.
The domestic hot water in the tank can reach a high temperature. It is thus essential to fit a
thermostatic mixing valve before water is distributed to the taps. The temperature setting at
the taps should comply with the regulations in force.
If COMPOSITE MATERIAL pipes (PER, PVC etc.) are used a temperature limiter must
be fitted to the tank output and adjusted according to the performance of the material
used.
