30. umbing Connections PLUMBING CONNECTIONS All plumbing work is to be undertaken by an authorised and Heat Tech approved contractor Water inlet and outlet connections are clearly marked It is very important that piping to the storage tank is correctly connected We recommend that all pipes be lagged before they are installed as this will ease the installation process A mandatory lever shut off valve must be positioned on both pipe connections These are required for servicing The Y shaped strainer supplied with the Heat Tech unit must be positioned on the inlet water pipe as near to the unit as possible If this is not installed the warranty becomes null and void Maximum minimum water pressures The minimum water inlet pressure required is 0 2Mpa The maximum water inlet pressure is 0 7Mpa Should pressure exceed this a pressure relief valve is to be fitted and needs to be checked on a regular basis to remove lime deposits and ensure it is not blocked Water may drip from the discharge pipe of the pressure relief device so this pipe must be left open to the atmosphere in a frost free environment Piping connections to hot water cylinder Connective pipe specification Circulating water outlet of main unit Circulating water inlet of main unit Circulating water outlet of water tank Circulating water inlet of water tank Cold water inlet Heatwater outlet Safety valve Return Connect the hot water outlet of th
