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 pump 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 power point in a dry
and flood free location. Do not plug the
power lead in.
Note: If you do not have access, arrange
an electrician to install one.
2. Thread your choice of rope through the
handle at the top of the pump.
3. Using the rope, lower the pump into
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.

PART 2: DISCHARGE SET UP
Now that your sump pump is positioned,
it’s time to set up the discharge pipework.
1. Create space for your discharge pipeline
at the top of your tank. Ensure the
space allows for the minimum pipe size
(internal 25mm).
2. Remove pump from tank to connect
discharge pipework. Once connected place
the pump and pipework back into the tank.
3. Fit a check valve to the discharge pipework.
The check valve will prevent fluid from
draining when the pump has stopped.
4. For easy maintenance install an isolation
valve to the discharge line outside of
the tank.
Note: When lifting or raising in and out of
position, use the handle or your choice of rope.
Do not lift via the power cable.
4. Check the set up so far. The surface
the pump sits on should be hard and there
should be enough clearance between
the base of the tank and suction inlet
(approx 50–100mm). This clearance helps
prevent sediment and debris from entering
the pump.

5. Connect the discharge pipe to the outlet by following the steps below:
a. Fit male threaded fittings with thread tape.
b. Install barrel union to facilitate easy removal for servicing.
c. Connect required pipework.
d. Ensure all pipework is supported independently of the pump.
Note: Discharge pipework may very depending on your unique or specific installation.

AUTO PRESSURE CONTROL
If you’re using a tank only system, follow the
steps below to install an Auto Pressure Control.
If you’re using tank and mains water source
switching, proceed to part 4: Vada Flow Boss
Digital Water Switch.
INSTALLATION
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.

3. Connect the VFB-APC inlet using pipe
with appropriate fittings (eg barrel union
and adapter). Ensure the VFB-APC is
installed with the arrows on the side of
the unit pointing up.
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.
4. Check the set up so far. Ensure that the
VFB-APC is braced or fixed so minimal
movement occurs once in operation.
PART 4: FIT A VADA FLOW
BOSS DIGITAL WATER
SWITCHING UNIT
If you’ve chosen to install a VFB-DSU with the
VFB-S35, proceed with the steps below.
1. Insert two mesh inline filters on the mains
inlet and pump inlet of the VFB-DSU.
Do not install or operate your
Digital Water Switch Unit in an
explosive environment, or near
combustible matter. Incorrectly
installed or tested equipment
may fail, causing severe injury
or property damage.
Brace inlet and outlet connections
while fitting the Digital Water
Switch. Any movement of
connections may disturb internal
seals and cause leakage.
Please read the full manual on
the Vada Flow Boss Digital Water
Switching Unit for complete
installation & operation instructions,
as well as troubleshooting and
product features.
The Digital Water Switch is
electrically connected. Ensure
that it is isolated from electrical
supply during installation and any
subsequent service work.

2. Where possible, install the VFB-DSU using
the wall mount bracket.
3. Connect the pump discharge pipe to the
port labelled ‘pump’ on the VFB-DSU.
Ensure that the submersible pump is raised
off the base of the tank, and a y-strainer
is installed prior to the VFB-DSU. Brace
the VFB-DSU to prevent movement while
connecting to all inlets/outlets.
Note: Pipe size should be in accordance with
pump outlet size – reduction may be required
immediately prior to entering the VFB-DSU.
4. Connect the mains pipework into the port
labelled ‘mains’ on the VFB-DSU.

PART 5: CONNECT
TO A POWER SUPPLY
Once your submersible pump is positioned
and pipework is completed, it’s time to connect
to power.
Note: Do not use extension cords. These can
cause a voltage drop.
1. Before plugging the power supply cord
into the power point, ensure the power point
is in a dry and flood free location.
2. Plug the power supply cord into the
10 Amp power point. Do not switch on.
3. If you are using an VFB-APC or VFB-DSU,
you will need to connect the IEC socket
from the pump to the IEC plug cord on
the device, then connect the power chord
to the power point. If you are connecting
directly to a power outlet (without an
VFB-APC or VFB-DSU), connect the
two supplier cords using the IEC socket
and connect to the power chord to the
power point.
Note: Supply voltage that is outside the
limits specified can cause the motor to
overheat leading to overload tripping, reduced
component life or seriously damage pump,
voiding warranty.
