Maintenance
The GRUNDFOS Max-E Boost has been designed for the minimum of maintenance. However, it should be inspected on a regular basis, as a failure of the set could potentially cause considerable water damage.
It is therefore recommended that a GRUNDFOS maintenance contract is taken out to cover maintenance of the set. For further details please contact Grundfos Europump Ltd for on 01942 263628.
However, it is the customer’s responsibility to inspect the Max-E Boost in addition to any maintenance contract to ensure the safety and correct operation of the set during the interim period between service visits.
Before removing the terminal box cover from the electric motor or before any removal/dismantling of the pump/motor unit takes place, ensure that the electricity supply to the control panel has been suitably isolated and cannot be switched on.
Care should be exercised when carrying out maintenance work as there may be sharp edges exposed which can cut skin.
Inspection
The Home Booster should be inspected at regular intervals of not more than six months, this must be carried out when the Home Booster has been shut down.
The following checks should be carried out at this time:
- Check that there are no leaks on the internal pipe work, the pump particularly around the shaft seal, and pressure tank.
- Check for any corrosion particularly on the pressure tank.
- Check that the pump shaft is free to rotate.
- Check that water does not appear at the valve on the pressure tanks when the air valve is depressed.
- Check that the pump operate quietly and smoothly.
- Check and adjust if necessary the precharge pressure of the pressure tank against the actual figures for the system.
- Check correct operation of the low level float switch in the storage tank.
Any large deviations from the system values should be investigated for a possible fault. Should any faults be found check the symptoms with the Fault Finding Chart, and if necessary contact Grundfos Pump Ltd for advice or Grundfos Europump for service.
Once inspection and any maintenance work is completed, ensure that the isolating valves are opened fully, and that the electricity supply to the booster set is restored. Check that the correct system pressure is achieved.
