6.3 Maintenance of drying hopper

1. Turn off the machine and discharge the drying hopper (1) as at change of material.

2. Open lid (2), disassemble and remove air distributor (30) being mounted by means of

a quick coupling (28). (On CD 25 the air distributor is assembled by means of a

split pin).

3. Disassemble sight glass (29).

4. Close slide valve (24).

Hopper (1) and air distributor (30) can now be cleaned using compressed air either from

the top or through the sight glass opening.

Please note, that when discharging through the discharge valve (31) the hopper may not be

entirely depleted, as granulate may remain on top of the slide valve and has to be disposed of.
