Carry out the electrical connection and
protection according to local regulations.
If rigid conduit is to be used, the hub must be
connected to the conduit system before it is
connected to the terminal box of the pump.
The protective earth (ground) symbol
identifies any terminal which is intended
for connection to an external conductor for
protection against electrical shock in case of a
fault, or the terminal of a protective earth
(ground) electrode.
Warning
Do not use the pump for flammable
liquids, such as diesel oil and
gasoline.
Warning
Observe local regulations setting
limits for manual lifting or
handling.
Warning
Before dismantling the pump, drain
the system or close the isolating
valve on either side of the pump.
The pumped liquid may be scalding
hot and under high pressure.
Warning

drop the pump head.
Warning
Risk of escaping vapor.
Warning
Switch off the power supply before
making connections.
Warning
The pump must be connected to an
external mains switch with a
minimum contact gap of
0.12 inches (3 mm) in all poles.
Grounding or neutralization must
be used for protection against
indirect contact.
If the pump is connected to an
electric installation where a Ground
Fault Circuit Interrupter (GFCI) is
used as an additional protection,
this circuit interrupter must trip
when ground fault currentswith DC
content (pulsating DC) occur.
The ground fault circuit interrupter
must be marked with the first or
both of the symbols shown below:
Warning
It must be possible to lock the
mains switch in position 0.
