PART 6: FIT A VADA FLOW
BOSS MECHANICAL WATER
SWITCHING UNIT 20MM
Follow these steps if you are installing a
Vada Flow Boss Mechanical Switch for a tank/
mains system.
1. Grab the rubber washer supplied and
place it on top of the Auto Pressure Control
(VFB-APC) outlet.
2. Hold the Mechanical Switching Unit
(VFB-MSU20) over the outlet and connect
the loose nut. Do not overtighten. The
rubber washer will lock this in place.
3. Connect the mains water pipe to the
VFB-MSU20 outlet labelled “mains in”.
4. Connect the house water pipe to the
VFB-MSU20 outlet labelled “to house”.
5. For easy maintenance down the track,
install an isolation valve into both the mains
and house water line.
