– Installation of ball siphon Variant 1
The ball siphon is installed in the bottom reservoir of the unit.
1. Open ball siphon, turn the mounting part a 1/4 turn (Fig.5).
2. Plug the mounting part in the condensation outlet from below, until the claw fasteners snap to the
sheet edge of the base plate (Fig.6).
3. Insert locking part and push upwards (Fig.7).
4. Then connect condensation hose DN 12 mm (not included in the delivery) to the hose connector on
the siphon housing and tighten by hand (Fig.8).

(NOTE: Ensure that the floating ball is in the housing!)
6. Connect the condensation hose DN 12 mm (length max. 1,5 m) to the drainage system on the
housing (siphon). In doing so, position the condensation hose at a gradient (Fig.10). Absolutely
necessary for proper condensation outlet.
There should be an open outlet after the installed ball siphon due to odour development from the
dried-up siphon.
– In order to guarantee the absence of leaks, the ball siphon must not be subjected to lateral
loads due to the condensation hose during installation!
– The drainage pipeline must not rise behind the siphon!
Ensure that there are no air pockets during installation!
– The condensation outlet must be frost-proof!
– The ball siphon must be checked and cleaned regularly (maintenance interval like filter
maintenance)!
