GENERAL INFORMATION
The Greenstar system filter is suitable for 22mm pipe central
heating systems and can be fitted anywhere on the main
heating circuit. The system should be flushed and a suitable
inhibitor added in accordance with BS7593 before installing
the Greenstar System Filter. Failure to comply with the
guidance will limit the effectiveness of the Greenstar System
Filter in protecting your boiler and central heating system.
However, in order to achieve the best protection for the boiler,
Worcester, Bosch recommend that the filter is fitted between
the last radiator and the boiler on a vertical run of pipework. In
determining a suitable location for installation, it isimportant to
ensure you allow adequate access for servicing.
