ASSEMBLY
WARNING!
Danger – high pressure and discharge of medium!
• When working on the product or the system, always switch off the
pressure and relieve the lines/containers.
• Wear protective equipment if media is hazardous.
Risk of injury from improper assembly!
• Installation must only be carried out by authorized technicians and
with the appropriate tools!
• Secure system from unintentional activation.

Assembling BBS-07 tank flange
→
Insert O-ring (2) by hand (do not use any tools or sharp imple-
ments) into the welded-in block flange (1).
→
Carefully attach grooved flange (3) (or clamp). Ensure that the
O-ring is in the correct position.
→
Screw connection using washers (4) and screws (5) (or half
flanges, threaded pins, washers and hexagon cap nuts).
Observe tightening torques (see "Tab. 2").

6.1. Welding in the tank flange
NOTE!
Leak due to damaged sealing elements!
• Do not weld in the assembled product. It is essential to remove
the O-ring and, if required, glass pane before welding and to pro-
tect the product from dust, flying sparks and other influences!
Leak due to damaged sealing contour!
• To ensure the sealing function, protect the sealing contour during
installation, welding and cleaning procedures.
→
Connect the parts positively in a protective gas shield.
When cleaning the weld seam by grinding or acid cleaning, observe
the following before assembling the connection:
• Carefully remove all grinding dust and acid-cleaning residue.
• Do not damage the label.
• There must be no material abrasion on the sealing edges. Material
abrasion will result in sharp-edged sealing contours and a damaged
seal.
• Check sealing contour for damage.
We recommend preparing a welding report.
