PREPARING FOR INSTALLATION
Inspect your pump, ensuring that it is well packaged and has not been damaged in transport. If the pump is damaged, report it to the Reece
branch where the pump was purchased. Warranty of these pumps is void unless they are operated in accordance with these instructions.
PUMP PROTECTION
Avoid using the electrical cable to lift or transport the pump.
VADA - V75-S
The pump is designed to be used with clean water
in a residential application. Do not use it with
alternative fluids, specifically abrasive, corrosive
or explosive fluids. Do not install or operate your
pump in an explosive environment or near
combustible matter.
Incorrectly installed or tested equipment may fail,
causing severe injury or property damage.
Fire and burn hazard. Modern motors run at high
temperatures. To reduce risk of fire, do not allow
leaves, debris, or foreign matter to collect around
the pump motor. To avoid burns when handling the
motor, let it cool for at least 20 minutes before
trying to work on it. A thermal overload switch
protects the motor from heat damage during
operation.
If the supply cord is damaged, it must be replaced
by the manufacturer, it’s service agent or similarly
qualified persons in order to avoid a hazard
Children should be supervised do ensure they do
not play with the appliance
Only qualified, licensed personnel should install
pump. The electrical installation shall be in
accordance with the national wiring rules (AS/NZS
3000) for class 1, IP44 rated products.
These instructions are a guide only. Users not
familiar with pumping equipment should seek
advice from people experienced in pump equipment
and installation.
Freezing conditions will damage the unit, because
when water freezes it expands. Ensure that the
pump is located so that it is not prone to freezing,
or ensure that the product is disconnected and
dried of water during cold conditions.
Pollution of the liquid could occur due to leakage of
lubricants
The pump is electrically connected. Ensure that it
is isolated from electrical supply during installation
and any subsequent service work.
This appliance is not intended for use by persons
(including children) with reduced physical, sensory
or mental capabilities, or lack of experience and
knowledge, unless they have been given supervi-
sion or instruction concerning use of the appliance
by a person responsible for their safety
INSTALLATION
Please pay careful attention to the following warnings signs and indications.

GENERAL INSTALLATION
1. Fitting an Auto Pressure Control or Mains Water Switch Over Device
If you are using a Vada Auto Pressure Control or Mains Water Switch Over Device with your pump, it needs to be mounted externally to the tank
in a suitable position in line with the delivery piping. This can be achieved using a mounting bracket. The unit should be mounted vertically in a
position which is out of the weather. Depending on the type of plumbing fitting used to connect to the inlet (underside) of the Auto Pressure
Control or Mains Water Switch Over Device, the unit may not be clamped firmly to the bracket. We recommend a spacer is fitted where
necessary.
For further instructions on connecting these devices, please refer to the manual for your unit. Ensure that the power lead remains disconnected
until you have completed the installation process.
2. Locating the Pump
Using the anchor point at the top of the pump, connect a nylon rope (provided) or a stainless steel cable suitable to sustain it’s weight. Anchor
the other end of the rope or cable so that it balances the weight of the pump as it rests upright at the base of the tank/well.
3. Power Source
Arrange for an electrician to install a 10A weatherproof outdoor power point near the pump if there is not one there already.
4. Suction
It is advisable to fit an automatic level control/float switch to prevent the pump from running without fluids.
The V75-S inlet is intentionally raised from the base to prevent the pumping of sediment. To raise this height further, use a length of 3” PVC pipe
and insert it into the specially designed base of the pump.
5. Discharge
The length and diameter of the discharge hoses/pipes will affect the pressure and flow rate at which your pump operates. Pressure ratings of all
components must exceed the maximum pressure of the pump by an appropriate safety factor. All pipe work should be supported independently
of the pump.

ELECTRICAL INSTALLATION
This appliance is not intended for use by persons
(including children) with reduced physical, sensory
or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision
or instruction concerning use of the appliance by a
person responsible for their safety.
The pump must be supplied by an outlet protected
by a residual current device or earth leakage circuit
breaker with a maximum rated residual current of
30mA
The pump is supplied with:
• A fixed cable featuring a weatherproof IEC socket
• A separate power cable which features a weatherproof IEC plug and a standard Australian 10 amp plug.
If connecting directly to a power outlet, simply connect the two supplied cords using the IEC socket and plug. If you are installing a Vada Auto
Pressure Control or a Mains Water Switch Over Device, connect the IEC socket from the pump to the IEC plug cord on the device. Before plugging
the power supply cord into the socket outlet, ensure that the socket outlet is supported by the delivery pipes at 3 metre intervals.
Ensuring there are no water traces on the connectors push them firmly into each other to ensure intended splash (water) proof protection. This
connection shall be separated again only for service purpose and only after the power supply is removed by unplugging the cord from the socket
outlet. The socket outlet shall be in dry and flood free location; preferably do not use extension cords for this very reason and because they can
cause voltage drop. Supply voltage outside limits specified in Model Data can cause motor overheat leading to overload tripping, reduced
component life or seriously damage pump and voids warranty.
For additional protection, the pump must be supplied from an outlet protected by a residual current device – RCD (also known as an Earth
Leakage Circuit breaker – ELCB) with a maximum rated residual current of 30mA.

The pump is designed to be used with clean water
in a residential application. Do not use it with
alternative fluids, specifically abrasive, corrosive
or explosive fluids. Do not install or operate your
pump in an explosive enviroment or near
combustible matter.
Liquid may be HOT, release pressure with care
before servicing.
The pump operator or owner must be provided
with this owner’s manual. This must be read before
operation, and followed during operation.
DO NOT RUN PUMP DRY
Ensure that your pump is submerged in water
before operating.
Pump should only be serviced by qualified
personnel. For best results, use only genuine ser-
vice parts. Be sure to prime pump before starting.
To avoid dangerous or fatal electrical shock hazard,
turn OFF power to motor and remove plug from
power outlet before working on pump or motor.
OPERATION
SERVICE AND MAINTENANCE
GENERAL CARE AND MAINTENANCE
Under normal conditions V75-S pumps do not need any type of maintenance. In order to avoid possible failures, it is advisable to periodically
check the 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.
If the pump is not going to be used for long periods of time it should be emptied completely, rinsed with clean water and put in a dry place.
Cleaning the filter
If the sucked water is not perfectly clean, it may be necessary to clean the filter with a steel brush to scrape the dirt accumulated on the external
surface. It is also possible to clean the internal section of the filter. Loosen the screw that fixes the filter to the body of the electropump and
remove it. Scrape the dirt with a steel brush and rinse it with clean water. If this is not sufficient, have the hydraulic parts cleaned by an
authorised centre.
START-UP/OPERATION
Open all valves in the suction and discharge lines. When the power is turned on, the pump will start to pump water. Without an Auto Pressure
Control or Mains Water Switch-Over Device, the pump will continue to operate until the power is switched off.
Most applications will incorporate an Auto Pressure Control or Mains Water Switch-Over Device which will stop the pump as soon as it has
pressurised the system it is connected to. For instructions on operating your pump with one of these devices, please refer to the manual that
came with your unit.
The system is now ready for use. If no water is delivered, check the troubleshooting section.
