•
The lifting unit is equipped with an activated carbon filter to ventilate the tank in the pump room.
If the auxiliary inputs are not used, fit the appropriate stopper.
Emptying toilets
•
Connect the horizontal outlet of the toilet bowl with the rubber sleeve of the lifting unit and tighten
the connection with the supplied clamp. If necessary, use a lubricant to prevent the rubber con-
nection from tearing.
•
Connect the drain pipe to the rubber connection piece, the pipe should have a diameter of 40
or 32 mm. Seal the connection with the clamp.
Checking the assembly of the check valve
If the waste water is to be pumped upwards, install the check valve as close as possible to the lifting
unit.
Emptying toilets and other sanitary units
Connect the drain pipes of the other sanitary
units with the rubber connectors supplied
and tighten them with the clamp. For shower
and bath wastewater, ensure that the si-
phon slope is at least 1 % (1 cm per meter)
so that the wastewater flows to the lifting
system by natural gravity.
If other sanitary units are connected along
the disposal circuit near the lift, install check
valves in the appropriate drain pipes to pre-
vent backflow. The slope of the horizontal
components must be at least 1 %.
