Dry, horizontal installation with brackets
Proceed as follows:
1. Fit the base stand or brackets to the pump.
See the dimensional sketches at the end of
this manual.
2. Mark and drill fixing holes in the concrete floor
or foundation.
3. Fasten the pump with expansion bolts.
4. Check that the pump stands vertically or
horizontally. Use a spirit level.
5. Connect the power cable.
Fit an isolating valve on the inlet
side of the pump and a non-return
valve as well as an isolating valve
on the outlet side.
6. Install the inlet and outlet lines as well as the
valves, if any. Make sure that the pump is not
stressed by the pipes.
