H7. STORAGE TANK INSTALLATION
IMPORTANT: Refer to Diagram – “Cold Water Valve Train Connections to Storage Tank”
Select the location of the storage cylinder to suit the panel and most frequently used hot water taps.
Connect the cold water supply to the cylinder inlet utilising a stop valve, non-return valve, pressure reducing
valve and, if required (listed in AS 3500.4 and local regulations), a cold water expansion valve.
Connect the hot outlet of the panels to the solar inlet on the cylinder.
Install the Pressure Relief ( P & T ) valve into the fitting on the top of the cylinder and run a ½˝ copper drain
line from the valve to a safe discharge point angled downwards. The drain line MUST be permanently open to
the atmosphere and MUST be unobstructed at all times. The Pressure relief valve MUST be operated every 6
months to remove lime deposits and verify no blockages. NOTE that water may drip from the pipe during normal
operation if an ECV (Expansion Control Valve) is not fitted to the system.
Open the discharge of the valve to prevent any premature pressure build up in the cylinder.
Connect the cylinder’s hot water outlet to the hot connection on a tempering valve and the tempering valve’s
outlet to the property’s hot water piping. Connect a cold water line from the cold valve train to the cold connec-
tion of the tempering valve.
