6 Final Mounting
After a ll pipes are pre--mounted with cutting--ring joints,
hoses, etc., the system can be completed.
During final mounting of the joints and later in the re-
peated mounting (each time after a connection was de-
tached), the tightening of the nut has to be carried out
without spanner extension and without increased ap-
plication of force.
While tightening the swivel nut during final mounting of
joints in free lines, the coupling is to be retained with a
second spanner (Figure 22).

ATTENTION
When filling in oil, pay attention to utmost cleanliness.
Also for new oil an according filling filter is to be used.
After mounting it is required to c arry out a pressure test
for tightness.
In joints show leaks, tighten the swivel nut only until the
connection is tight.
Further tightening might damage the connection.
Finally, the entire system is to be rinsed, see SCHOT-
TEL Instructions 1100933.
