22 VADA FLOW BOSS HORIZONTAL MULTISTAGE PUMP VFB-HM110 INSTALLATION MANUAL
Adjust the Cut-In Pressure
After installing the VFB-APC and VFB-MSU25,
the cut-in pressure must be adjusted to ensure
a smooth and reliable changeover.
1. Turn on the Pump and VFB-APC.
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 (roughly, this will be
3.5 full 360° turns).
4. Confirm the pressure has been correctly
adjusted by slowly opening an outlet and
checking the gauge on the side of the
VFB-APC. If the pump starts when the
gauge drops to 2.2 bar the cut in pressure
has been successfully adjusted.
5. Your pump solution is now ready of
operation!
