ASSEMBLY STEPS
Keep the head of expansion and the cone always clean
and greased. If there is dust, dirt or debris, use a clean cloth
that does not loose lint, then apply a thin layer of grease on it.
Do not lubricate it too much.
Fully insert the fitting
into the pipe.
If you can not insert
the fitting into the pipe,
remove the fitting and
expand once more.

Screw in the expander head of the appropriate
measure on the tool.
Insert the expander head
into the pipe, then push the trigger; the expander
head will expand and retract continuously while
the trigger is pressed. Each time the segments
retract, repeatedly and gently push the pipe inward
on the expander head several times (*) until the pipe
and ring are at level with the shoulder of the expan-
sion head. The expander head must not be pushed
inwardly of the pipe so as not to block the move-
ment auto-rotation. Finally, remove the pipe when
the segments retract and then release the trigger.
Wipe off excess grease from inside the pipe.

The joint can be pressurized after 30 minutes with
temperatures up to + 5 °. At lower temperatures, this
time increases according to the table below. The
maximum test pressure, which must not be excee-
ded, is 20 bar (2.0 MPa). At room temperature, after
about 6 hours, the joint will be as strong as the tube.
(*) The approximate number of expansions depends on the diameter of the pipe:
16 x 1,8: 4 16 x 2,2: 6
25 x 2,3: 8
25 x 3,5: 20
20 x 1,9: 6 20 x 2,8: 12
32 x 2,9: 12
