Let’s get started!
Before you begin, ensure all relevant
instructions have been followed and
your pump has been primed.
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.
6. Set up the suction line, installing an
isolation valve, swing check valve,
Y-Strainer and barrel union.
7. Use a pump cover
to protect your
set up from the
elements and
increase product
lifespan.
