Type BBS-25:
→
Insert clamp seal into the threaded connection before screwing the
connection element together.
EPDM seals:
Do not install using grease or oil!
If required, glycerin can be used as an installation aid.
Clamp seal must be located centrically and firmly and tightly in the
designated groove and must not protrude into the pipe connection.
6.3. Installing the pipe connection
→
Ensure that the seal is located correctly in the sealing contour.
→
Assemble both connection parts so that they are in alignment
(concentric deviation and angular offset of the pipe ends
max. +/–0.5 % of the outer pipe diameter)
Type BBS-03
→
Pull union nut over the liner.
→
We recommend lubricating the thread with suitable grease.
→
Manually turn union nut clockwise on the threaded connection.
Ensure that the connection turns freely, do not use force.
→
Tighten union nut using a suitable tool,
observe tightening torque
(see "Tab. 2").

We recommend using flanges from DN 40.
Type BBS-06
→
Insert hexagon bolts through the screw holes in the flange.
→
Push circlip over the ends of the bolts.
→
Turn nuts on to the bolt threads, tighten by hand.
→
Tighten bolts crosswise using a suitable tool until flange sheets are
firmly situated one on top of the other.
Observe tightening torque

NOTE!
Damage to the connection element!
• Do not use any tools to install the clamp.
→
Manually place clamp over the connection.
→
Insert clamp screw into the designated slot, but do not use force.
→
Check that the clamp is seated correctly.
→
Carefully and evenly tighten the wing nut by hand until both pipe
components are firmly situated one on top of the other.
7. START-UP
WARNING!
Risk of injury from improper operation!
Improper operation may result in injuries as well as damage to the
connection element and the surrounding area.
• Before start-up, ensure that the operating personnel are familiar
with and completely understand the contents of the operating
instructions.
• Observe the safety instructions and intended use.
• Only adequately trained personnel may start up the equipment/the
connection element.
• Following assembly, ensure a controlled restart.
• When starting up the equipment, ensure that no unauthorized volt-
age increases and pressure surges can occur.

NOTE!
Damage to the seals when cleaning the pipeline systems.
• Clean the pipeline systems preferably with a cleaning agent which
does not damage the seals.
• Do not clean the connection elements with wire brushes or
machines which cause abrasion of the surface.
• When using mechanical pipeline monitoring devices, ensure
that they do not damage the sealing elements (also the sealing
contour).
Damaged seals must be replaced!
8. MAINTENANCE
WARNING!
Danger – high pressure and discharge of medium!
• Before loosening the lock nut or locking clamp, always turn off the
pressure and vent the lines.
• Wear protective equipment if media is hazardous.
• Lock nuts or locking clamps of the connection elements on pres-
surized lines may be retightened only by technicians in consider-
ation of special precautions.
• When shutting down the equipment, ensure that no unauthorized
voltage increases and pressure surges can occur.
• Following maintenance, ensure a controlled restart.
Have the connection elements serviced regularly by technicians!
We recommend a maintenance interval of 6 months.
Inspection and maintenance work includes in particular monitoring and
ensuring the
• leak-tightness,
• identification,
• proper mode of operation of the safety and warning devices.
