MAINTENANCE
Isolate from the power supply before checking the pump. Any damage to the connecting cable should only be
repaired by a qualified electrician!!
To ensure highest operational safety and reliability at lowest possible cost, the following routine checks are always
recommended at 6 month intervals:
- Check pump and pipe work for leaks
- Check non-return valve and screen (if installed) for debris
- Check pressure tank diaphragm pressure (if installed)
If there is danger of freezing, then it is necessary to completely drain the pump using the drain plug at the bottom of the pump
housing. For prolonged stand-down periods (e.g. winter shutdown) the pump needs thorough cleaning, complete draining
and dry storage. On re-commissioning check for free rotation by briefly switching on the pump on. Then follow installation
procedures set out in this manual.
Any dry-running of the pump must be prevented as it will lead to failure of its internal pump parts!! (ECOJET Electronic
PRESSCONTROL version has built in run-dry protection)!!
