•
Never attempt to open the clamps of a
pressurized manhole.
•
Don’t remove the blind cover from a
coupling that is under pressure. Con-
nect the material hoses before the sys-
tem is pressurized.
•
Never attempt to loosen or tighten the
clamps of a discharge cone that is un-
der pressure.

Loading
You can check the pressure in the silo tank
by means of the manometers. If necessary,
you must open the ventilating valve (1).
Ventilating valve
Depending on the product, observe the
specified filling levels.
Preparing to fill
Connect
the
potential
conductor
(if
equipped).
If the potential conductor is not
connected, static charges can
cause sparks and thus explosi-
ons.
•
Connect the potential conductor
while filling, emptying and clea-
ning.
•
Check that the silo vehicle is not
pressurized. If it is pressurized,
use the ventilating valve to remove
all the air from the silo vehicle.
•
Check that all the shut-off devices
such as discharge cone, material
emptying couplings gate valves,
blind covers, ball valves are clo-
sed.
•
Depending on the loading method,
open one of the manhole cover or
loading couplings to vent the tank.
Start loading
•
Insert the loading nozzle into the
manhole (2) or connect the loading
hose to a loading coupling (3)
Filling manhole and filling neck
•
Authorize the loading personnel to
begin the loading procedure.
•
Load the silo tank evenly via the
manholes or loading coupling.
•
Monitor the loading procedure.
Terminate the loading procedure
•
Check whether the product flow
has stopped.
•
Pull out the loading nozzle or re-
move the loading hose from the lo-
ading coupling.
•
Close the manhole or loading co-
upling.
•
The ventilation valve (1) opened
before starting loading must re-
main open until pressurized disc-
harge is made.
Stop loading
•
Close all the valves in the air lines
and material hoses and fit the blind
covers.
