4. Hydraulic connection
Connect the water heater’s inlet and outlet with pipes or fittings that are able to
withstand temperature in excess of 80° C at a pressure above the working pressure.
Therefore, we advise against the use of any materials which cannot resist such high
temperatures.
Connect the hydraulic line as shown in the figure. The outlet is on the left (red) and
the inlet is on the right (blue). Do not over-tighten the safety valve or alter the
position of the safety valve without authorization. A cold pipe is connected under the
valve and a hot pipe is connected with the valve outlet. (Wrap all hydraulic
connections with PTFE tape.) Fill the appliance with water and check if the appliance
or the hydraulic line leaks. If no leakage is detected, switch on the electricity mains
and start the trial run.
If the network pressure is closed to the rated valve pressure, it will be necessary to
apply a pressure reducer far away from the appliance.
To avoid any possible damage to the mixer units (taps or shower), it is necessary to
drain any impurities from the pipes. Otherwise, impurities may cause damages to the
mixer units.
