6. 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.
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.

→
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”).
