Selection of the conservation agent
In order to prevent dust particles and foreign bodies from penetrating into the
pump or the conservation agent from leaking out, please secure the liquid
input and output openings with the delivered protective plugs or screws.
Warning
Water or DI-water should not be used as conservative liquids. They germinate
already after a few days and build a biofilm which can later block the pump.
1.4.2
Dismantling of the system
Put the drive out of operation by turning down speed to 0 rpm and by
switching off the voltage supply. Make sure that the procedure described in
the chapter 1.3 has been completed.
Now that the pump has been stopped you may remove it from the system.
Protect the inlet and outlet openings of the pump with adapted protective
plugs or screws.
