Important information on installation
•
Observe suction lift and line diameter,
see section
•
Shorten hoses at right angles.
•
Ensure that there are no loops or kinks in the
hoses.
•
Keep suction line as short as possible.
•
Route suction line up towards the suction valve.
•
Installing a filter in the suction line protects the
entire installation against dirt and reduces the
risk of leakage.
Hose connection procedure
1. Push union nut and tensioning ring across hose.
2. Push cone part fully into hose, see fig.
.
3. Attach cone part with hose to corresponding
pump valve.
4. Tighten union nut manually.
– Do not use tools!
5. Tighten up union nuts after 2-5 operating hours if
using PTFE gaskets!
6. Attach deaeration hose to the corresponding
connection (see fig.
) and run into a container or
a collecting tray.
