3. INSTALLATION for contractors
3.3 Water connection
Observe the regulations imposed by your local water board. Install the cold water supply line in
accordance with Fig.5.
To facilitate an easy connection to the water system, the equipment will be supplied with union nuts
and flat gaskets for connection to the inlet and outlet.
Insulate the DHW line in accordance with local regulations and AS3500 4.2. Please adhere strictly to
the order of fittings on the cold water side ( see Fig.5) . Prior to installation: Flush out the line.
Install a 500 kPa pressure limiting valve when the water pressure is higher than 500kPa, this is
recommended for all installs as the water pressure can fluctuate depending on the time of the day .
Condensate drain
The condensate drain from the WWK 300 is channeled to a drain via a hose ( 1 /2 ” diameter ) .
To protect against the risk of corrosion, make the connection with
the flat gaskets. The use of thread seal on the union connections
is not acceptable
