HYDRAULIC CONNECTION

You must install a frost-free safety device (or any other pressure
relief device), which is new, with 3/4" (20/27) dimensions and 0.7
MPa (7 bar) pressure on the inlet of the water heater, which
complies with local standards.
The dimensions of the space required for the correct installation
of the appliance are specified in the figure on page 9.
A pressure reducer (not supplied) is required when the supply
pressure is greater than 0.5 MPa (5 bar) - which must be attached
to the main supply.
Connect the safety device to a drain hose, kept uncovered, in a
frost-free environment, with a continuous downward slope for
the release of excess water from the heater or if you are
emptying the water heater.
The operating pressure of the heat exchanger circuit must not
exceed 0.3 MPa (3 bar) and its temperature must not exceed
100°C.
