Mandatory installation of a safety device in a frost free location (or

any other new device which limits the tank pressure) to 850 kPa

according to the nominal pressure, with a size of 3/4'' on the input

of the water heater, respecting the local regulations .

Operate regularly the discharge of safety device to prevent scaling and

check that it is not blocked.

To drain the device switch off the power and the supply of cold water,

open the hot water faucets and manipulate the safety valve.

The pipes used must support 1 MPa (10 bar) and 100°C.

Cold Water Inlet

Cold water piping should be provided with a 350 – 500 kPa Pressure

Limiting Valve at the point of cold water connection to the

water heater. In addition to the Pressure Limiting Valve, it is a

requirement of AS 3500.4 & NZBC G12 that both a Stop Valve and a

Non Return Valve are installed upstream of the Product.

No parts (stop valve, pressure reducer, etc.) must be placed between the

pressure limiting valve and the cold water inlet of the water heater,

apart from a copper pipe.

Note: Since limited water discharge from Pressure Limiting Valve is

normal in the heating operation, the discharge pipe needs be

connected to external drain.

Hot Water Outlet

Where a maximum hot water delivery temperature is specified by local,

state or federal regulations, a tempering valve shall be installed at

the hot water outlet, as required.
