5.6.1 Filling information
The Baxi 600 Combi is supplied with an "Easy-Fill" permanent filling link.
The permanent filling link is a device to allow filling and repressurising of
the heating system. The link has been tested and approved to be left con
nected after use. It is not necessary to remove any temporary loop or oth
er part of the device after filling and repressurising.
Filling & repressurising is achieved by the operation of a spring loaded
green lever incorporated in the cold mains inlet part of the link. Full fitting
and operating instructions are included with the permanent filling link.
If not using the "Easy-Fill" permanent filling link normal regulations apply.
