Installation procedure:
• Centralize the seal using the pin on the m. connection.
• Place the seal on the pin of the wall adapter.
• Screw the shut-off valve onto the threaded connection by hand. Keep the pressure reducer at
an angle of 45° in front of the desired position.
• Tighten the lockable quick-fitting coupling with the open-end wrench. To do this, use only
the open-end wrench SW 36 which is available as an accessory. As the tightening torque in-
creases, the pressure reducer is rotated as well. Tighten the quick coupling until the pressure
reducer reaches its desired position. This will give a gas-tight connection.
