ADJUSTING CUT-IN PRESSURE
For a smooth, more reliable changeover
between tank and mains water, adjust
the cut-in pressure from the default 1.5
Bar to 2.2 Bar. Follow the steps below
accordingly.
1. Ensure your pump is primed. Then, turn on
the power at the power point.
2. Locate the adjustment screw at the back
of the VFB-APC.
3. Using a flat head screwdriver, turn the
adjustment screw clockwise until you
reach the correct pressure (approx 3.5
full 360° turns).
4. Confirm the pressure has been correctly
adjusted by slowly opening a tap outlet
and checking the gauge on the side of the
VFB-APC. If the gauge reads 2.2, the cut-in
pressure has been successfully adjusted.
Your pump solution is now ready for operation!
