PUMP DIAGRAM

Important information

• The pump must be earthed with no strain placed on the electrical cable.
• All maintenance should be carried out with the power supply disconnected.
• The pump is designed for clean water use only, i.e. water containing no solid particles. Pumping muddy water or water containing suspended solids will severely reduce the lifespan of the unit and falls outside of the factory warranty.
• Extending the cable will affect your factory warranty. Always make use of an approved extending plug adapter.
• The pump should be installed in a ventilated, undercover area to protect the unit against direct sunlight, rain and spray from any irrigation system. A JoJo pump cover is recommended for best protection.

INSTALLATION

The foundation should be solid enough to support the pump. It is recommended to secure the unit by bolting it to a concrete or paved surface.

Foundation

Before building the foundation, take the following into consideration:

• The placement of the pump incl. the direction of inlet/outlet.
• The height: ensure that the water level in the tank is higher than the suction side of the pump.

Mounting

• A level base is essential to ensure the pump shaft is aligned horizontally.
• The pump suction line and fittings must all be on a horizontal plane to ensure there are no high points in the pipeline where air can get trapped.
• The discharge line and fittings must be on a vertical plane.

Piping

• The suction and discharge pipes should be supported independently by utilising pipe hangers and support blocks – this will prevent strain on the pump joints and casing.
• Before making a connection, always check the pipe alignment to ensure it is correct.
• The inlet and discharge pipe should align with the pump to ensure there are no bends or kinks that might affect the flow.
• The inlet and discharge pipe/connections must correspond with the design specifications of the pump as it may directly affect the efficiency and power consumption of the pump.
• The diameter of the suction and discharge pipe must be equal or greater than that of the ports of the pump.
• When used as an alternative water supply for a home, install non-return valves to ensure no back pressure to the municipal supply or the pump.

PRIMING INSTRUCTIONS

IMPORTANT: always prime the pump before use to ensure proper functionality and to prevent possible damage to any of the components.

1. Ensure that the ball valve between the tank and pump is open.
2. To allow the air in the pump to escape and the pump to be filled with water by gravity feed, unscrew the priming screw. The suction line and pump should slowly fill with water until a steady flow is visible from the air valve. Note: this also ensures that all air  has been removed from the casing and suction piping.
3. If after a few seconds water is not visible from the air valve, fill the pump volute manually until it is overflowing.
4. Put the priming screw back in place and then tighten. Do not over tighten.

OPERATING INSTRUCTIONS

After priming the pump, do the following to test it and ensure proper operation:

1. Check that the ball valve (a) between the tank and the pump is open and that the discharge valve (b) on the pump is closed. Note: it is always advised to install a ball valve between pump and tank for maintenance purposes.
   

2. Insert the plug into the main power supply and switch the plug on. The power indicator light of the flow controller must be illuminated.
   

3. Open the discharge valve (b), the pump should start automatically.
   

4. Close the discharge valve (b), the pump will switch off within 15 to 20 seconds (this is a built-in safety feature that protects the pump).
   This tests the pressure controller operation.
   
   

5. Close the inlet valve (a) and open the discharge valve (b). The pump will switch on and run for 15 to 20 seconds. The pump should then stop operating and the failure light on the flow controller should be illuminated.
   This tests the run dry operation.
   

6. Open the inlet valve (a) and press the reset button on the flow controller. The pump will start running.

7. Close the discharge valve and wait for the pump to switch off. Open the discharge valve a little bit so that the pressure on the pressure gauge decreases slowly. Observe at what pressure the pump switches on again. Adjust the adjustment screw to  increase/decrease the desired cut-in pressure (the pressure at which the pump switches on). Note: the adjustment screw does not determine the pressure at which the pump switches off.
   After completing steps one to six, the pump will be ready for use.

MAINTENANCE INSTRUCTIONS

IMPORTANT: it is advised to run the pump at least once a month to prevent the impeller from getting stuck. Should the impeller get stuck (typically due to sediment in the water), you can follow these guidelines to clean and test it.

To clean the pump, you will require:

| | | |
---|---|---|---|---

A CLEAN CLOTH

| SIZE 8 SPANNER| FLAT POINT SCREW  DRIVER| WATER PUMP PLIERS|

100/120 GRIT SAND  PAPER

Open the pump to confirm if the impeller needs cleaning.

1. With the pump inlet facing you, remove the 3 x 6mm screws from the front casing.

2. Split the front cover from the pump.

3. Move the cover away from the pump. Be careful not to damage the electrical cord.

4. If the wear-plate or impeller is dirty, dirt will be visible as indicated in the image above.
   If the impeller needs cleaning, simply do the following:
   

5. Using a piece of sandpaper gently clean the surface where the impeller runs.
   

6. Next clean behind the impeller and casing. Once done, wipe both sides with a cloth.
   

7. Make sure the O-Ring is in place (as indicated in the image above), before re-fitting the front cover.
   

8. Replace the front cover and refit the 3 x 6mm screws to it.
   

9. Tighten the 3 screws on the cover, making sure not to over tighten them.
   Test the pump to ensure it has been cleaned properly.
   Note: we recommend testing the pump before connecting it to the water supply.

10. Insert the plug into the main power supply and switch it on. The pump should start up immediately and run for 20 seconds, after which it will shut down (a built in safety feature to prevent dry run).

11. Reconnect your pump to your water supply as per the operation instructions on pages 5 and 6 in this manual.

12. Reset the pump by pressing the reset button on the flow controller.
