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.
