11 Service and Maintenance
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.
There is a risk of scalds!
