Quick Guide
This is a simplified guide to the installation and commissioning of the Grundfos Home Booster. Please refer to the individual sections
in this document for precise details for each step.
There is no need to open the pressure manager and change the DIP switch settings, as they are factory set.
INSTALLATION
Install the Home Booster on to a flat and level solid foundation.
Conect the mains water supply.
Connect the overflow pipe work.
Connect the discharge pipe work.
Connect the electrical supply cable.
COMMISSIONING
Spend some time venting the pump carefully, if the pump contains air it will not gerate pressure.
To vent the pump open the discharge valve and a outlet fitting (tap) at low level.
Vent the pump for 30 to 60 seconds, using the vent screw on the pump.
TESTING
Switch on the electrical supply.
The pump will start, and the pressure will begin to increase as shown by the indicator lights.
Once the pressure has built up, close the isolating valve within the Home Booster. The pump will run-on for several tens of seconds
and then stop.
Open the isolating valve within the Homer Booster, the pressure will begin to fall if the outlet fitting has been left open. The pump will
then start again and the pressure increase. The pump will continue to run while there is a flow demand.
Close the outlet fitting, the pump will stop after a short time. If the pump does not stop, then there is a flow demand which is causing
the pump to continue operating.
If the pump continues to run even though the outlet fitting is closed, then close the isolating valve within the Homer Booster, the
pump should stop again.
Investigate the cause of the flow demand, for example filling toilet cistens etc.
