    6.5.3 Filling the system CAUTION: supervise all filling/top-up operations. CAUTION: before filling/topping up the system, disconnect power to the units. CAUTION: the system must always be filled/topped up in controlled pressure conditions (max 1 bar). Make sure that a pressure reducer and safety valve have been installed on the filling/top-up line. CAUTION: the water on the filling/top-up line must be appropriately pre-filtered from any impurities and suspended particles.

  • Page 17: System Unloading

    In the event of observing a water leak, it is mandatory to replace the component, by loosening it with a wrench, as pictured below. 6.5.6 System unloading If the unit has to be completely drained, first close the manual inlet and outlet gate valves (not supplied) and then disconnect the pipes arranged externally on the water inlet and outlet in order to let the liquid contained in the unit escape (to make the operation is easy, it is advisable to install two drain cocks interposed between the unit and the manual gate valves externally on the water inlet and outlet).
