Start-Up And Maintenance - Graf 400 Mode D'installation

The sieve insert is removed for cleaning. Rinse the basket thoroughly with water until all the pores are
clear. We recommend cleaning every 4 - 5 weeks (more often in autumn when dead leaves accumulate).
Cleaning intervals may vary depending on the degree of soiling and the connection surface.
The sieve basket must be pressed down slightly each time it is re-inserted after cleaning to make sure the
surrounding seal fits snugly. Also make sure that, before starting up and after every maintenance, the
extraction attachment is aligned at a 90° angle to the intake to prevent large dirt particles from becoming
caught on the basket handle.
The replaceable filter substrate (art. no. 231010) must be replaced every 2 - 5 years depending on the
degree of soiling. When the filter basket is maintained, check the filter bags for blockages or soiling.
Please note: If water backs up to the overflow level, even during light rain, both the filter basket
and the filter bags should be checked. When the required permeability is no longer achieved, the
filter and/or substrate must be replaced.
