Vent-assist air pressure too low, or
hose to scrap container and/or
container not air tight
Sieve not level, discharge end
pitched down

path causing blockage

Contact your Nordson representative for repair information.
Corrective Action
Reduce the venturi transfer-pump air
pressure. If a HDLV system, contact
your Nordson representative.
Check the transfer-pump air supply
and pressure. Check the transfer
pumps, pickup tubes, and hoses for
blockages. Check the fluidising plates
and the powder in the colour module
hoppers for contamination.
Check the powder in the colour
module for contamination
Change to a more coarse screen
mesh. Refer to AZO E360B technical
manual for procedure.
Remove the screen frame from the
sieve. Adjust the screen tension
according to the AZO E360B
technical manual.

can cause clogging.

connections and seals.
