Additional Equipment; Maintenance And Storing - Happowa Spreader 4000 User Manual

6. Additional equipment

Different kinds of limit switches can be used to control
the operating of the Spreader applicators. There are
three options: a mechanical limit switch, a magnetic limit
switch and a control relay.
The limit switch can be mounted e.g. to the pick-up of
the silage machine.
A control relay can be used if there is an available signal
coming from the silage machine for controlling the
applicator. Check the availability of signal in the manual
of the silage machine.
The limit switch can be connected either to the controller
or to the pump's limit switch coupling.
NB: Only use the original components.
NB: Supplying the limit switch coupling with voltage not
allowed!

7. Maintenance and storing

The acid applicator must always be cleaned after use
by pumping clean water through the whole system.
External cleaning is also necessary. During cleaning, the
electronic components must be protected from water.
After cleaning, the pump and the electric couplings must
be carefully dried.
Do not use a pressure washer for cleaning the pump!
Use the appropriate personal protective equipment!
After use the acid applicator must be stored in a dry
place, protected from sunlight. If the acid applicator
is stored in a cold place, pump antifreeze through the
system before storing to prevent freezing.
