Hot and Cold Water Connections
All plumbing connections must be performed by a licensed plumber in accordance with local authority regulations.
The cold water inlet connection to the storage tank is 3/4 FI. All pipes and valves must be insulated as per the current AS/NZ 3500.4 Section
8.2. The cold water inlet requires the following valve train please refer to system diagram page for correct installation.
• Approved isolating/non return valve
• 500 kPa Pressure Reduction Valve (PRV) valve
• 700 kPa Expansion Control Valve (ECV)
The maximum inlet water pressure rating is 750kPa. Cold water supply pressures exceeding 500kPa a 500kPa Pressure Reduction valve
shall be installed immediately downstream from the Duo valve.
The hot water outlet from the tank is ¾ inch FI. All hot water pipes must be insulated by UV stable & appropriately rated insulation.
