The pump is nearly free of maintenance. If the
pump was not working for a longer time or the
system is heavily contaminated could the rotor
be blocked.
It will shown by flashing of the upper LED light.
By removing of he motor head ( loosening the
union nut and remove the motor head ) the
impeller is accessible and can be also removed.
By doing this the blockade can be solved and /
or the pump can be cleaned.
Tighten the union nut with 30 Nm torque.
Switch off the power to the system before
performing maintenance, cleaning or repair
work, and secure it against unauthorised
reactivation.
Allow the pump to cool down in the event of
high temperatures and system pressures.
