Ordering Fuel - Viessmann VITOFLEX 300-UF Operating Instructions Manual

Notes on filling the fuel store
For horizontal discharge
If the fuel store is empty, fill the fuel store until the
articulated arms or spring blades are covered by
approx. 30 centimetres of fuel.
Turn the "Silo filling" key switch. The arms are rotated
for 90 seconds and then come to rest. After this, the
function of the "Silo filling" key switch is blocked for
10 minutes.
Fill the fuel store until it is full.
Fill the fuel store without delay when there is still more
than approx. 30 centimetres of fuel above the articula-
ted arms or spring blades.

For flexible agitator discharge
For the "Silo filling" function, see page 16.
Systems with funnel discharge
So as not to damage or block the screw conveyor, it
must be moved to a vertical position when filling the
fuel store.
If it can be ensured that the specified pressure condi-
tions in the fuel store can be maintained, the system
can be switched on while the fuel store is being filled.
This ensures that the screw conveyor remains vertical.
