Do not connect inlets to the drain connection!

For maintenance work or if a system malfunctions, the tank is emptied through the drain connection. If an inlet is connected to the drain connection, the tank cannot be emptied.

Manually pump out the collection tank for maintenance or if the lifting unit malfunctions. It is recommended to install a diaphragm hand pump. CAUTION! If the lifting unit malfunctions, backflow into the inlet can break the collection tank. Shut off the inlet and drain the collection tank.
