10.7.5 Checking assembly
Fig.26
When the valve is closed, the lower edge of the cleaning hood (1) should be flush
with the underside of the abutment (2).
10.7.6 Reconnect the cleaning hose
Prerequisite:
• The cleaning hose is made of plastics. When screwing the cleaning hose on,
it can become easily constricted in the area of the sealing disc and the
cleaning hose can become detached. Therefore, during assembly of the
cleaning hose, insert sleeves must be used.
Cleaning hose preparation
Carry out the following steps:
1. Cut off the cleaning with the hose cutter at a right angle.
2.
Place insertion sleeves up to the edge of the hose.
3. Grease the threads and cone of the fitting, as well as the sealing disc and the
threads of the union nut.
