Performance Curves

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.
• Carefully read the instructions before adjusting any settings. Please contact JoJo should you need assistance.
• 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.
• The booster pump is equipped with a draining screw at the bottom of the suction/discharge casing. It is advised to drain the unit when temperatures fall below 0°C.

| Recommended suction pipes:| Recommended discharge pipe:
---|---|---
0.75kW| • HDPE (minimum 1” or 25mm)
• Helical coil reinforced flexible hose 1 ” or 25mm| Copper, HDPE or any SABS approved piping (minimum 3/4” or 22mm)
1.5kW| • HDPE (minimum 1 ½” or 40mm class 6)
• Helical coil reinforced flexible hose 1 ½” or 40mm| HDPE (minimum 1 ½ ” or 40mm class 6)

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.
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.
• 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.
• 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. Remove the priming screw located on top of the pump.
2. Fill the pump volute manually with water until it overflows. Note: this unit is equipped with a spring-loaded non-return valve and will not prime automatically (even if connected to a tank).
3. Put the priming screw back in place and then tighten, (do not over tighten). Ensure that there are no leaks.

OPERATING INSTRUCTIONS

1. Ensure that the power supply cable is connected correctly.
2. The booster pump is designed to operate with a 230V single-phase power supply. Voltage variance is maximum 10% up or down. Further variation will damage the electrical motor.
3. The suction and discharge piping should be of rigid characteristics, be able to withstand pressure of up to 6 bar, be air tight on the suction side, and water tight on the discharge side.

SETTINGS

IMPORTANT: changing the default settings is not recommended, as it enables the unit to respond optimally to potentially harmful system conditions.
This booster pump may operate safely for 1 to 2 minutes after dry run conditions have been logged.
Please follow the steps on the following pages to set up your pump.

1. Press “MODE” until reaching the desired category.
   01.1 Mode “UP” must always be selected for installations where the pump is installed on ground level and supplies pressure parallel to, or vertically up into a system.
   • The screen will display the working pressure (bar).
   • Press “+” to increase the set pressure.
   • Press “-” to reduce the set pressure.
   • The new set point will flash five (5) times before saving the value.
   • The recommended operating range is between 2 bar and 5 bar. Do not exceed 4 bar for residential use.

2. Press “SET” to skip between functions B01 to B05.
   02.1 B01: START-UP PRESSURE
   • When B01 is displayed and “SET” is pressed, the start-up pressure can be adjusted as a percentage of the working pressure. The default ratio is set at 70%. Use commands “+” or “-” to increase or decrease this ratio.
   For example, working pressure set at 3.0 bar and ratio set at 70%:
   3.0 bar x 0.7 = 2.1 bar
   Once water usage has stopped, the pump will allow system pressure to drop to
   2.1 bar before starting up.
   02.2 B02: DIRECTION OF ROTATION
   • Must ALWAYS be set to “00” to ensure the correct direction of rotation.
   02.3 B03: DRY RUN PROTECTION
   • When “B03” is displayed and “SET” is pressed, the screen will display a value between 0 and 1.5 bar. The default is set at 0.15 bar and is the pressure at which the pump will switch off when it runs dry or against low back pressure, for example, as caused by a burst discharge pipe. Using “+” or “-” will increase or decrease this value.
   Note: it is not recommended to change this default setting as it enables the unit to operate in its highest efficiency zone and most accurately mimics municipal pressure supply conditions.
   02.4 B04 and B05:
   • “180” Dry run – DO NOT CHANGE THIS SETTING.

3. Indicator lights and fault codes:
   03.1 Mode “UP”:
   • The “POWER” light will be illuminated.
   • The “RUN” light will illuminate when the pump is operating.
   • The “RUN” light will flash when the pump is operating but unable to reach the set pressure. This is not unusual, as the application for household supply and irrigation supply vary vastly in flow demand.
   • The “LEAK” light will illuminate in the event of a pressure leak in the discharge line.
   • If an error code appears on the screen, please refer to the trouble shooting guide on page 7.
   • Press the “HAND START/CHECK” button to reset all fault codes. Press again to resume automatic operation.
   • Operating under the “UP” mode will disable the “TIMING” light and function.
   03.2 Mode “TIME”:
   • “TIME” retains all settings of “UP” mode, but allows for the selection of a restart time.
   For example, “3H” will start the pump every 3 hours without the system demanding an automatic start. This function is important for applications where the unit may not be required to operate for extended periods of time e.g. a holiday home, weekend retreat, etc.
   • Daily starts keep the rotating equipment in good condition and prevents damage to bearings.
   03.3 Mode “DOWN”:
   • Must ONLY be selected for installations where the pump is installed on the upper level and supplying pressure parallel or vertically down into a system. Selecting this option will reduce the overall pressure delivered by the pump to protect against over pressurizing lower lying systems.

TROUBLE SHOOTING GUIDE

If an error code appears on the screen, please refer to the below guide for more information.

0.00E+00| Low voltage supply (below 130V)| The supply voltage is too low. This is generally a fault from the local municipality and can damage your pump.| Turn the pump off and disconnect it from the power source. Proceed to contact a registered electrician to inspect your power supply.
---|---|---|---
0.00E+00| High voltage from supply (above 280V)| The supply voltage is too high. This is generally a fault from the local municipality and can damage your pump.| Turn the pump off and disconnect it from the power source. Proceed to contact a registered electrician to inspect your power supply.
0.00E+00| Pressure transducer disconnected/ faulty| Caused by a loose cable or damaged pressure transducer.| • Check the transducer cable to see if it is damaged or unplugged.
• If within the 12 month warranty period and the cable is intact, return the unit to the supplier you purchased it from, otherwise contact JoJo for further assistance.
0.00E+00| Motor temperatures exceeding operating limits| The pump is overheating.
This is generally due to poor ventilation caused by installing the motor fan end closer than 100mm from the nearest vertical surface e.g. a wall or covering.| • Ensure that the motor is installed with sufficient spacing (min. 100mm) between a surface and the motor fan to allow for sufficient cooling.
• Ensure the motor is has sufficient ventilation.
0.00E+00| Locked rotor| Caused by objects such as stones, plant matter, string, sand, or mineral build-up entering the system from the supply side and lodging in the pump casing, thus preventing the impeller from rotating.| • Remove the suction and discharge piping and inspect the inlet and outlet for any visible obstruction/s. Remove the obstruction/s if visible.
• If within the 12 month warranty period and the error code continues to display, return the unit to the supplier you purchased it from, otherwise contact JoJo for further assistance.
0.00E+00| Variable speed drive
PC board fault condition| Caused by power spikes, and under voltage or over voltage that damage the PC board. Continued faults of this nature indicate power grid instability and can lead to permanent damage of the electronic circuitry.| • IMPORTANT: this is not covered by the warranty.
• Please contact JoJo for further assistance. Even though this is not covered by the warranty, we will assess the pump to determine the extent of the damage and advise whether a repair is possible.
