Mains pressure water supply
The water heater is designed to operate at mains pressure by connecting directly to the mains water supply.
The water heater is supplied with a temperature pressure relief valve with a pressure rating of 1000 kPa. If an
expansion control valve has been installed on the cold water line to the water heater, this should have a
pressure rating of 850 kPa.
The maximum mains water supply pressure for the water heater is 800 kPa if an expansion control valve is
not installed, or 680 kPa if an expansion control valve is installed. If the mains supply pressure in your area
exceeds these values, a pressure limiting valve must be installed.
The supply pressure should be greater than 350 kPa for true mains pressure operation to be achieved.
