Connection to Plumbing (cont.)
Water Inlet Pressure Limiting Valve and Shutoff Valve Connection
The unit is a closed outlet water heater and is intended to operate at the pressure of the water mains, where
the flow of water is controlled by one or more faucets/valves in the outlet line.
The unit can be installed into any type of commercial or residential construction as per the current Plumbing
Standards.
However, it is mandatory for a water pressure limiting valve and a shutoff valve to be connected in series with
the unit’s cold water inlet connection (6).
• The unit is designed to operate at 10 MPa/10 bar/150 PSI.
• The installation of a pressure limiting valve – a mandatory requirement – ensures that excess water pressure
applied, as result of water hammer and/or other circumstances, does not stress the appliance unduly.
• The inline water pressure limiting valve must be rated at 5.0 bar/72.5 psi/500 kpa.
• The shutoff valve installed must not be a non-return type valve.
