5.5 Cellar drainage
If the installation room is to be drained automatically, particularly if there is a risk of
flooding or seepage water, we recommend installing one of our Ama-Drainer
submersible waste water pumps.
This pump must be selected in accordance with the local conditions:
(Head H [m] = H
Static
+ H
Losses
).
The sump in the floor of the installation room should measure at least 500 x 500 x
500 mm.
If manual drainage is preferred, a hand diaphragm pump can be ordered as
accessory. In this case, the required sump dimensions are 300 x 300 x 500 mm.
CAUTION
Discharge line for cellar drainage connected to the discharge line of the lifting unit
Flooding of installation room!
▷ Run the separate discharge line for cellar drainage above the flood level before
leading it into the sewer.
▷ Never connect the discharge line for cellar drainage to the discharge line of the
lifting unit.
▷ Install a swing check valve.
5.6 Electrical connection
DANGER

Danger of death from electric shock!
▷ Always have the electrical connections installed by a trained and qualified
electrician.
▷ Observe regulations IEC 60364 and, for explosion-proof models, EN 60079.
