3.8 connection oF MAins wAter supply For floor standing models: On the front of the unit there is a label to identify the connection ports. Please check this before making any connection to the unit. 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. 3.1 - 3.7 for a suggested installation layout. Draining taps must be located in acessible postions to permit the draining of the whole cylinder. The taps must be a minimal size of at least 15mm nominal size (preferably 22mm), and manufactured in accordance with BS 2879:1980. When installing the expansion vessel it can either be connected directly to the combination valve (see Figs 3.8 - 3.10), or it can be installed remotely using the flexible hose supplied. iMportAnt note:- When installing the expansion vessel, Do not install the expansion vessel vertically as air can become trapped in the expansion vessel resulting in potential vibrations through the cylinder and pipework. When using the flexible hose to remotely install the expansion vessel away from the control valve, again, ensure that the vessel is not installed in a vertical position where it can trap air. See below for acceptable installation practices. ✘ ✔ ✘ ✔ 9
