*If the incoming mains pressure to your property is greater than the specified 1000 kPa (10 bar),
you MUST fit a pressure reduction valve of appropriate capacity upstream of the VFB-DSU. The
recommended pressure is 500kPa as per AS/NZS 3500.

14 VADA FLOW BOSS JET PUMP VFB-J40 INSTALLATION MANUAL
INSTALLATION
PART 1: PUMP LOCATION
Let’s get down to business.
Note: Ensure the pump is being installed by a
qualified, licensed personnel. The pump should
be in good condition and should be used in a
residential application.
Note: The length and the diameter of the
discharge pipe impacts the pressure and flow
rate the VFB-J40 can deliver.
Note: all components used must have a
pressure rating that exceeds the maximum
pressure of the pump by an appropriate
safety factor.
1. Ensure you have access to a 10A
weatherproof outdoor powerpoint in a dry
and flood free location. Do not plug the
power cable in.
Note: If you do not have access, arrange
an electrician to install one.
2. Find a location for your pump as close to
your water source as possible. Use either
a poly, or concrete base slab to mount the
pump. This location should be stable, dry
and on a separate footing from your home.
Note: It is recommended the pump should
be no further than 3 metres from the tank.
In accordance with AS 3350.2.41
we are obliged to inform you that
this pump is not to be used
by children or infirm persons and
must not be used as a toy by
children.
The Auto Pressure Control is
pre-set by the manufacturer
with a pump start pressure of
1.5 bar (this can be adjusted).
The maximum pump pressure
must be 0.8 bar above the start
pressure for the pump to reach
automatic shut-off.
The Pressure Control has a safety
valve preventing water emission
in case of diaphragm damage.
DO NOT REMOVE.
Ensure that the power lead
remains disconnected until you
have completed the installation
process.

15
PART 2: SUCTION SET UP
Now that your jet pump is positioned, it’s time
to set up the suction pipework. This will run
from your tank/water source to your pump.
1. Select pipe that is re-enforced and crush
resistant (non-collapsible), with an internal
diameter of 25mm or larger.
2. Install an isolation valve at the tank/water
source outlet.
3. If the tank is below ground, install a foot
valve at the point of entry on the suction line.
4. Connect the suction pipe to your Jet Pump.
Ensuring both an inline filter and barrel
union have been installed in the suction
line. The inline filter prevents dirt and debris
entering the pump and will prolong product
lifespan.
Note: The length of the suction pipe should
only run between 1–2 metres.
Note: Install a check valve for optimal
performance should the tank be above ground
but lower in elevation than the suction inlet of
the pump.
5. Check that all fittings connected to the
suction pipe are airtight.

PART 3: DISCHARGE
SET UP
Now that your suction pipework is installed,
it’s time to set up the discharge pipework.
1. Select a pipe with an internal diameter
of 25mm or larger (this is the size of the
discharge outlet port).
2. Connect the pipe to the Jet Pump using
a 25mm barrel union.
Note: It is crucial that you use the
recommended pipe size until at least the first
pipe branch (T piece) is reached.

PART 4: PUMP PRIMING
Before moving on, its important to prime the
pump. This means filling the pump with water
and expelling all air from within the pump
casing.
If you’ve set up a surface mount pump, follow
steps outlined in Part 4A.
If you’ve set up a pump mounted above a tank,
follow steps outlined in Part 4B.
PART 4A: PRIMING A
SURFACE MOUNT PUMP
AND TANK
1. Ensure the water level in your tank sits
above the tank outlet. This will ensure
the pump does not draw in any air during
priming.
2. Open the isolation valve on the tank. If there
are any leaks, repair these immediately.
If no leaks are present, proceed.
OPEN

17
3. Close the tank isolation valve and then
remove the priming port plug on the top of
the pump casing.
4. Slowly open the tank isolation valve
allowing water to fill the suction line and
pump casing. This will expel the air as the
water fills the suction line and pump casing.
5. Once all air is expelled a steady stream of
water will trickle out.
6. Close the isolation valve and replace the
priming port plug. The isolation valve
must be re-opened prior to operation.
Your pump is now primed. Before pump
operation ensure there is sufficient water
inside the tank.

PART 4B: PRIMING A PUMP MOUNTED ABOVE A TANK
1. Ensure a foot valve or non-return valve is fitted to the end of the suction line.
2. Remove the priming port plug on the top
of the pump casing.
3. Slowly fill the pump casing and suction
line with water through the priming port
(best done with a funnel) allowing air
to vent as the water fills the suction line
and pump casing. If there are any leaks,
repair these immediately. If no leaks are
present, proceed.

If you are installing the Vada Flow Boss Digital
Water Switch for a tank/mains application, skip
to Installation Part 7 on page 23.
1. Keep the VFB-APC unplugged from the
power source.
If extending the cable used
for connection, ensure the
connection is being carried out
by a qualified professional with
an electrical license.
Never take the electronic board
out of the control box. The wiring
diagram inside the front panel will
show you how to make correct
connection. Wrong connection
will destroy the whole electronic
circuit.

4. Check the set up so far. Ensure that the
VFB-APC is braced or fixed so minimal
movement occurs once in operation. If the
distance between the pump and highest
outlet exceeds 15m, adjust the cut-in
pressure on the VFB-APC.

2. Position the Auto Pressure Control
(VFB-APC) between the pump and the first
outlet.
Note: If you are installing the VFB-APC directly
onto the Jet Pump, use a 25mm barrel union.
If you are installing the VFB-APC between the
pump and first outlet, use pipework with a
minimum internal diameter of 25mm.
Note: Do not install an outlet between the
pump and VFB-APC.
Note: the pipe must have an internal diameter
no smaller than 25mm until the first tee branch.
3. Ensure the VFB-APC is installed with the
arrows pointing up.
