GENERAL INSTALLATION
1. Fitting an Auto Pressure Control or Mains Water Switch Over Device
If you are using a Vada Auto Pressure Control or a Mains Water Switch Over Device with your pump, connect it either directly to the top of the
pump or in a suitable position in line with the delivery piping. For further instructions on connecting these devices, please refer to the manual
supplied with your unit. Ensure that the power lead remains disconnected until you have completed the installation process.
2. Locating the Pump
Find a location for your pump as close to your water source as possible. Ensure that this location is stable, dry and on a separate footing from
your home. To do this you can mount the pump on a concrete base.
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
This is the most important part of the installation as errors will cause significant problems for the system in performance and longevity.
A gate valve must be installed at the water source outlet. To maintain optimum performance from your pump, the suction pipe should be:
•
Kept to the shortest length practical.
•
Re-enforced crush resistant (non-collapsible) hose or pipe.
•
All fittings should be air tight.
•
Pipes should be equal to or larger than the diameter of the suction/inlet port.
•
When pumping from a well/pit etc. a foot valve should be installed on the suction pipe.
•
Optional: Fitted with a suction Strainer/Filter*
*In-line strainers/filters are only recommended for pumps fitted with a Vada Auto Pressure Control or a Mains Water Switch Over Device. Regular
maintenance is required to keep them clean and provide maximum pump pressure.
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.
If you want to test that the pump is operating correctly prior to having the plumbing connected, attach a hose with a trigger nozzle to the top of
the pump or the connected discharge hoses/pipes.
6. Pump Priming
Ensure that there is at least 200mm of water in your tank, (i.e. that the tank outlet is covered, and the pump will not draw any air into the system).
Open the gate valve on the water source. Check for any leaks, and repair these if necessary.
•
If no leaks are present, remove the priming plug to open the priming port on the top of the pump case. If the tank is above the level of the
pump, water will start to run out of this port. Replace the priming plug carefully. Your pump is now ready to run.
•
If the tank water level is below the level of the pump, you will need to fill the pump body and suction line. Remove the priming plug and fill
the pump body and suction line using a funnel.
