Notes: When installing, slide the separator (8) fully into the female
connection. Push the subsequent balanced ue (4) 50 mm (dim. "S")
into the female connection of the separator and always secure in this
position, e.g. with pipe clips DN125 (5) or with a locking screw on the
air side.
Lubricate the pipe ends and gaskets for easier installation (use
silicone-free grease only).
Prior to installation, liaise with your local ue gas inspector regarding
the required inspection piece (3) (10). Adapter (2) is always required.
