When the dispenser-sided connection line is de-
pressurised, disassemble the safety break part
on the dispenser side.
Remove and dispose severed breaking bolts in
both parts of the safety break.
Before reassembling and reusing the safety break,
check it for any damage ( scratches / deformations ).
Reuse is excluded in case of damaged func-
tional or sealing surfaces as well as deformati-
on of the body
.
Ensure that the safety break parts are free of any
debris.
REASSEMBLY AFTER SEPERATION
Replace valve seal. Make sure the seal is not
damaged by sharp objects or overstretching.
Ensure correct alignment of the seal. The open
side of the seal should face away from the
coup ling surface.
Screw in new breaking bolts into the safety break
part with replaced valve seal. Use wrench
( 4 mm ).
NOTE:
A
pressure and tightness test
with
nitrogen in a suitable environment must be
carried out.
A check with water instead requires a
complete and thorough drying afterwards.
The following pressure levels must be
approached > 1 min. each and checked for
leaks:
• 1,5 x working pressure ( 51 bar )
• 0,1 x working pressure ( 3,4 bar )
After a successful test connect the
safety break to the dispenser and
hose assembly as shown in chapter
'Installation'.
After the safe installation to the dispenser and of hose assembly, a pressure and tightness
test must be performed. It is essential to check that the safety break and hose assembly
connections are tight under pressure and do not leak.
NOTE
:
Pressurise system gradually while checking for leaks.
Push the second safety break part onto the
other so that the breaking bolts fit perfectly into
the holes provided.

Then carefully mount the second nut.
Before tightening the upper nut securely counter
the lower nut so as
not
to exert any force on the
breaking bolts.
After the breaking bolts have been installed,
the safety break is ready for a pressure and
tightness test
.
Carefully and loosely fit a washer and nut per
breaking bolt by hand. Then carefully tighten by
a maximum of 45°/ 1/8 turn with a wrench ( 8 mm ).
Use a screwdriver to lock the breaking bolt.
NOTE: Before using the nozzle again, it is essential to test its functionality. To do this,
observe the respective manufacturer's instructions for the nozzle.
