For units up to 300 litres it is recommended that all mains cold water supply pipe work is a minimum of 22mm, with the exception of model ST 50 ProTech where 15mm can be used. For 500 litre models the supply should be 28mm. An isolating valve should be installed between the cold water supply and the cylinder for servicing. ALL PIPEWORK MUST BE FLUSHED TO AVOID DAMAGE TO THE CONTROL VALVES.
Please refer to FIGS. 2.1, 2.2, 2.3, 2.4, 2.5 for a suggested installation layout.
