Warning
The pump must be connected to an external mains switch with a
minimum contact gap of 3 mm in all poles.
Earthing or neutralisation can be used for protection against
indirect contact.
If the pump is connected to an electric installation where an earth
leakage circuit breaker (RCD/RCCB) is used as an additional
protection, this circuit breaker must trip when earth fault currents
with DC content (pulsating DC) occur.
The earth leakage circuit breaker 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.
Warning
At high liquid temperatures, the pump may be so hot that only the
button should be touched to avoid burns.
The surface of the pump may be so hot that it may cause burns or
personal injury.
Warning
Before dismantling the pump or related parts, drain the system and
close the isolating valves on both sides of the pump as the
pumped liquid may be scalding hot and under high pressure.
Warning
If the power supply cable is damaged, it must be replaced by the
manufacturer, the manufacturer’s service partner or a similarly
qualified person.
