General information
The Greenstar System Filter is suitable for 22mm pipe central
heating systems and can be fitted anywhere on the main
heating circuit, except between the boiler and the feed and
expansion on an open vent system. 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 is important to ensure you allow adequate access
for servicing.
