Electrical installation
Fit and tighten the screw holding the
clamp to 8 Nm ± 1 Nm. Do not apply
more torque than specified even
though water is dripping from the
clamp. The condensed water is most
likely coming from the drain hole under
the clamp.
Check the position of the clamp before
you tighten it. Incorrect position of the
clamp will cause leakage from the
pump and damage the hydraulic parts
in the pump head.
WARNING
Electric shock
Death or serious personal injury
- Lock the main switch in position 0.
