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.

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.

Ensure that the power lead remains disconnected until you have completed the installation process.

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.

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.

13

INSTALLATION

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.

2. Remove pump from tank to connect discharge pipework. Once connected place the pump and pipework back into the tank.

Discharge pipe min 25mm

3. Fit a check valve to the discharge pipework.

The check valve will prevent fluid from draining when the pump has stopped.

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).

4. For easy maintenance install an isolation valve to the discharge line outside of the tank.

25mm Isolation valve

50–100mm


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: 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.

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.

The Digital Water Switch is electrically connected. Ensure that it is isolated from electrical supply during installation and any subsequent service work.

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.

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.

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.

1. Before plugging the power supply cord into the power point, ensure the power point is in a dry and flood free location.

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.

OFF

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.

2. Plug the power supply cord into the

10 Amp power point. Do not switch on.

OFF


4. Ensuring there are no water traces on the connectors push them firmly into each other.

6. Connect the pump and pressure control device to the power supply and turn the power on. The green “Power On” LED will illuminate.

ON

Note: This connection should be separated only for servicing and only after the power supply is removed by unplugging the cord form the socket outlet.

5. For additional protection, the pump should use an outlet protected by a residual current device – RCD (also known as an Electrical Leakage Circuit breaker

– ELCB) with a maximum rated residual current of 30Ma.

If you’re using the VFB-S35 with an APC continue to page 22.

SERVICE & MAINTENANCE

Turn off power to motor and remove plug from power outlet before working on pump or motor.

Liquid may be HOT, release pressure with care before servicing.

Cleaning the in-line filter

To avoid a build-up of debris and dirt, Vada recommends cleaning out the in-line filter once every 6 months, or as required. To do so, follow the steps below.

1. Remove the inline filter aka y strainer.

Pump should only be serviced by qualified personnel. For best results, use only genuine service parts. Be sure to prime pump before starting.

Under normal conditions, the Vada Flow Boss

Submersible Pump VFB-S35 requires low maintenance and is simple to service.

To avoid possible failures, we recommend periodically checking the flow and pressure supplied and current absorption:

• A decrease in pressure is a symptom of wear.

• An increase in current absorption is a sign of abnormal mechanical friction in the pump and/or motor which may be caused by debris caught in the impeller.

2. Use a steel brush to clean the debris from the filter.

3. Rinse with clean water.


STORING THE PUMP

If the pump is not going to be used for long periods of time (e.g. 6 months), it should be emptied completely, rinsed with clean water and stored in a dry, shaded place.

PUMP PERFORMANCE CURVE

Pump curves are a great tool to understand your pumps performance capabilities, in relation to head

(metres) and flow (litres per minute). Pump curves can be interpreted by tracing your finger along the head (metres) across to flow (litres per minute).

For example, in the pump performance curve below, you can see that if the Vada Flow Boss

Submersible Pump VFB-S35 has a discharge head between 20–14m (200–140kPa), then the pump will produce between 44–66 l/min.

Check that the pump motor is not blocked by external objects that are causing the pump to seize.

1. Disassemble pipework and pump housing.

2. Clean impellers.

It is recommended to call a pump technician or licensed professional.

Check that the power cables and relative connections are not damaged.

Check if the pump winding is damaged and replace if necessary.

This should only be done by a qualified electrician.

If a pressure controller has been installed, check that it is functioning correctly and turning the pump off at no flow.


SYMPTOM

The pump will not start, but is making noise.

CAUSE

The pump capacitator may be damaged.

The pump shaft may be locked or jammed.

The electronic card in the pressure controller may be broken.

* Only applicable if a pressure controller has been installed.

Voltage failure.

The pump may be jammed.

SOLUTION

Contact a qualified service technician to confirm the capacitator is damaged.

Check for blockages that may be causing the pump to seize:

1. Turn the power off.

2. Rotate the fan and ensure it spins freely with no resistance.



If a pressure controller has been installed, the electronic card in the controller may need to be removed and replaced with a new card, or a new unit entirely.


Check with a licensed electrical contractor to ensure voltage is correctly supplying the unit. Refer electrical data in manual.

If there is a humming sound coming from the pump motor, this may be due to debris or damage to the impellers being blocked and no longer turning or damage due to incorrect pump selection.

1. Check pump internals for debris.

2. Check system pump requirement.


31

TROUBLESHOOTING

SYMPTOM

The pump will not start, but is making noise (continued).

CAUSE

The pump may be jammed.

The pump stops after running for a short period of time.

The single-phase, pump motor thermal may have tripped.

The power supply does not conform with the data on the nameplate.

A solid object may be blocking the pump impellers.

SOLUTION

This may also be a failed capacitator caused by the above. Please replace or call a pump technician.


The in-line strainer or filter on the suction line pipework may be blocked:

1. Close the isolating valve on the suction line.

2. Remove/clean in-line strainer or replace if necessary.

3. Once in-line strainer has been cleaned, open isolating valve on suction line and retry for pressure.

There may be debris caught within the first impeller not allowing pressure to be created.


2. Clean impellers.


Potential water failure. If complete water failure, then it is possible the motor bearing has seized.

1. Turn power off.

2. Remove the fan cover.

3. Gently spin the fan to see if it spins freely.

If the fan is hard to move or does not move at all this indicates there is major damage with the motor bearing. Call a pump technician.

This is reset automatically once the motor has cooled.

Check the voltage on the power supply cable leads. If it does not conform, contact your local Reece branch.

Check for solid objects that may be blocking the impellers.


2. Clean impellers.



SYMPTOM CAUSE

The liquid being pumped may be too thick.

There may be rotation resistance in the pump fan.

There may be cavitation in the pump

(demand for water is higher than it can pump).

* Cavitation can be identified by the noise of the pump. You will hear a bubbling, crackling sounds like marbles rattling inside the pump casing.

There may be excessive liquid temperature.

The pump motor thermal cut out protection setting, or fuses may not be suitable.

The pump power cable may be damaged.

The pump motor may be damaged.

SOLUTION

Contact your local Reece branch. You may need a different type of pump for the application.

This pump is for clean, debris free water only.


2. Remove the fan cover.

3. Rotate the fan by hand and it should rotate freely.

The length of the suction pipe may be too long, or the internal diameter may be too small:

1. Reduce either the suction height or distance.

2. Increase the suction pipe internal diameter to same size as the pump inlet or larger.

The liquid temperature should be below 40°C.

Check liquid temperature using a thermometer.

Check protection devices with respect to rated current of pump. The circuit breaker should be rated to 10A.

Replacement parts required. Contact a pump technician or call your local Reece branch.

There may be resistance in the pump motor shaft.



3. If still jammed, or damaged, replacement parts required. Contact a pump technician or call your local Reece branch.

33

TROUBLESHOOTING

SYMPTOM

The pump stops after running for a short period of time (continued).

CAUSE

The suction pipe internal diameter may be too small.

Debris may be caught in the pump impeller.

The in-line strainer on the suction line may be blocked.

There may be presence of leaks which are higher than the minimum flow of 0.6 l/min.

SOLUTION

A suction pipe size that is too small will cause high pressure loss or cavitation. Increase the pipe size to an internal diameter that is the same size as the suction inlet, or larger.

Note: This means for a 25mm inlet pump a 32mm PN12.5 Poly Pipe must be used.



2. Clean impellers.


Check for blockages in the in-line strainer:




If the pump is turning on, then off in short durations there may be a leak in the pipework.

1. Close the isolating valve on the discharge line of the pressure controller to see if the issue continues.

2. If it does not, check all taps, pipes, irrigation solenoid valves & toilet cisterns for leaks.

3. If it does continue, then check pressure control and suction pipe for debris.

4. If found, repair or replace pipework.

Contact the Reece store where the product was purchased from.

TROUBLESHOOTING

SYMPTOM

Pump will not stop

(continued).

Pump is turning on then off in short durations.

CAUSE

The check valve on the suction line may be blocked in the open position.

A pressure controller or mains switch over device has not been installed on the pump.

The pump may be sucking air.

SOLUTION

The check valve may be blocked by debris.

1. Shut the relevant isolation valves.

2. Disconnect suction line.

3. Inspect check valve.

4. Clean or remove debris.

5. Ensure that an in-line strainer/filter is fitted in the suction line between the pump and the tank.

Without a pressure controller or mains water switch-over device, the pump will continue to operate until the power is switched off.

Brass flow detection valve on pressure controller may be jammed in the open position.

The pump may not be providing sufficient pressure.

Check that the level of liquid in the tank has not dropped below the minimum priming level.

There may be also be a leak in the suction pipe:





1. Remove the pressure control.

2. Inspect internals.

3. Clean or free debris.

4. Ensure that an in-line strainer/ filter is fitted in the suction line between the pump and the tank.

There could be potential of air still in the suction pipeline.

1. Check the pressure gauge on the side of the pressure controller to determine if that model pump is operating correctly when referencing its pump curve.

2. Check that the level of liquid in the tank has not dropped below the minimum priming level.




SYMPTOM CAUSE

There may be presence of leaks which are higher than the minimum flow of 0.6 l/min.



SOLUTION



The suction pipe diameter may be too small and causing high pressure loss or cavitation. Increase the pipe size to an internal diameter that is the same size as the suction inlet, or larger.


There may be debris caught within the first impeller not allowing pressure to be created:


2. Clean impellers.


The pump may not be suitable for the water application. Check to confirm pump suitability on page 9.

The in-line strainer or filter on the suction line pipework may be blocked.




If the pump is turning on, then off in short durations there may be a leak in the pipework.

1. Close the isolating valve on the discharge line of the pressure controller to see if the issue continues.

2. If it does not, check all taps, pipes, irrigation solenoid valves & toilet cisterns for leaks.





37

TROUBLESHOOTING

SYMPTOM

The pump vibrates and operates noisily.

No water is delivered from the pump, or the pump performance has decreased.

CAUSE

The pump and pipework may not be firmly anchored.

There may be cavitation in the pump

(demand for water is higher than it can pump).


The pump may have been incorrectly sized for the application.

The rainwater tank may be empty.

SOLUTION

Fix the pump and pipes securely.




Contact the Reece store where the product was purchased from.

1. Check the tank level.

2. If empty/low, wait for the tank to refill.

There may be no power supply to the pump.

1. Ensure that the power is turned on and check the connection to the power point.

2. Fuse may have blown. Contact a pump technician or contact your local

Reece branch to replace fuse.

3. Electrical power line may have been damaged.

Check the isolation valve and ensure that it is open at the water source (tank outlet).

The isolation valve on the suction line may be shut.

There may be bad signal from the float switch.


Check the installation and operation of the float switch. Refer to page 19 on how to install the float switch.


SYMPTOM

No water supply at all.

CAUSE

The pump may be sucking air.

The in-line strainer on the suction line may be blocked.

The mesh filter in the digital water switching unit may be blocked.


The liquid column may be above the check valve on the discharge line.

The rainwater tank may be empty.

There may be blockage in the pipework.

SOLUTION

Check that the level of liquid in the tank has not dropped below the minimum priming level (8m).

There may be also be a leak in the suction pipe:





If you do not regularly clean the filter, it will clog up and cause the pump to fail.




If a digital water switching unit is installed:




The weight of water can force the check valve on the discharge line to close. This prevents air being expelled from casing and suction line, affecting the pump’s self-priming performance.

Ensure water is completely drained above the level of the check valve.

1. Check the tank level.

2. If empty/low, wait for the tank to refill.

1. Close the isolating valves on the suction and discharge lines.

2. If switching from tank and mains water, close the isolating valve on the mains line also.

3. Check pipework and devices for debris

4. If found, clean or replace pipework.

5. Open isolating valves again to check and ensure flow rate is sufficient.

39

TROUBLESHOOTING

SYMPTOM

No water supply at all (continued).

The Green LED light on the pressure controller is not on.


Pump “Error” or

RED LED signal appears on the

Pressure Controller.


CAUSE

The mains water valve may be closed.


Incoming mains water pressure may be greater than 1000kPa.


Power to the pressure controller may not have been turned on.

The pressure controller may not have restarted.

SOLUTION

Check that the mains water isolation valve is open.

Fit a pressure reduction valve to reduce incoming mains pressure.

Check the power supply.

The pump may have failed to prime

(i.e. the tank is empty, no water is being detected).

The pressure controller is still in ‘lock out’ mode, meaning it has detected a loss of prime (tank empty). If the tank has been refilled with rainwater, the pressure control can be manually reset by pressing the “Restart” button on the device.

The pressure controller is protecting the pump against loss of prime.

1. Simply press the “Restart” button.

2. If the system fails again, the unit is detecting that there is air in the suction pipe and has shut down to protect the pump from long term damage.

3. Check there is water in the tank.

4. Check the pressure gauge on the side of the pressure control to determine if that model pump is operating correctly when referencing its pump curve.

5. Activate all appliances/outlets sequentially from the nearest to the furthest outlet. Repeat if necessary.

6. If problem persists, please contact the Reece branch where the pump was purchased from.

The suction pipe diameter may be too small and causing high pressure loss or cavitation. Increase the pipe size to an internal diameter that is the same size as the suction inlet, or larger.



SYMPTOM CAUSE SOLUTION

There may be debris caught within the first impeller not allowing pressure to be created:


2. Clean impellers.


The system may have a large pipe network to charge and the pump is running high flow with no pressure.

1. Close the isolating valve on the discharge line to almost 90% closed.

2. Restart to ensure the pump has head pressure and fills the line slowly.

Once the tank has filled with water to an adequate level prime the pump and press the ‘Reset’ button.

The Digital Water

Switching Unit has gone into “loss of prime” (no water is being delivered to pump).


The pump may have failed to prime

(i.e. the tank is empty, no water is being detected).

The valve on or between tank and switching unit inlet may be closed.

The mesh filter in the water switching unit is blocked.

Open the isolating valve on the suction line between the tank and switching unit.

No water is delivered from mains.

* Only applicable if application is using a water switch device.

There may be no mains water available.




Check the isolation valve on the water meter.
