Installation of a diaphragm hand
pump
NOTICE
Do not connect inlet to the emergency drain!
The collection reservoir is pumped out via the emergency drain for inspection work
or in the event of an accident. Do not connect inlets to the emergency drain! The
collection reservoir cannot be drained in case of emergency otherwise!
The collection reservoir must be manually pumped out if maintenance work is carried
out or if the lifting unit malfunctions. It is recommended to install a diaphragm hand
pump for this purpose.
CAUTION! If the lifting unit malfunctions, there is backflow into the inlet and the
collection reservoir can burst! Shut off the inlet and drain the collection reservoir.
