3. Pumped liquids
The pump can be used for pumping water/glycol
mixtures up to 50 %.
4. Installation
4.1 Changing the control box position
5. Electrical connection
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
When loosening the clamp, do not
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 currents with 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. Type and
requirements as specified in EN
60204-1, 5.3.2.
