Caution
The connection piece for direct connection to the device is not supplied by the manufacturer.
The package includes a siphon and two reducing pieces DN 40/30.
Caution
It is important to watch how you turn syphon. The arrow on the cap should point in the direction of water

Caution
The syphon connection is suitable for a base frame of 125 mm at any time at overpressure, if only
Hmin > 60 mm. In the case of a underpressure, the height of the base of 125 mm corresponds to
underpressure of 700 Pa, or Hmin = 80 mm.
