bottom edge of the
condensate tray unit

Scheme of overpressure siphon (type SF-P 400 PR):

the condensate
tray unit

Vacuum siphon (SF-P 300)
- contains a ball that serves as a non-return valve for the correct function of the siphon not flooded with water and
prevents the penetration of odours into the unit.
The siphon must be fitted to the unit gas-tightly via the enclosed rubber sleeve. Max. usable
vacuum 1100 Pa.
Overpressure siphon (SF-P 400 PR)
- the siphon must be completely filled with water to prevent the penetration of odours from the sewer into
the interior of the unit when it is shut down. Suitability of the overpressure siphon can be found by visual inspection. When the device is running
and started, the water must not be forced into the drain pipe after the siphon has been filled. Max. usable overpressure 1100 Pa.
