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 certied safety unit or non-return ap and safety valve assembly is
obligatory.
If the network supply pressure is ≥ 5 bar, a pressure reducer must be tted 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 lter must be tted 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 t 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 tted to the tank output and adjusted according to the performance of the material
used.
