Variable Speed Drive (VSD) defined:
The speed at which the pump runs varies as per the
pressure requirements to ensure minimal energy is
being used.
• Unit intended for clean water usage, i.e. water
containing no solid particles, such as drinking water,
non-potable water piping systems, and irrigation.
• Unit suitable for use with water temperatures
ranging from 2 to 80 degrees celsius.
• 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 aect 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.

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.
Foundation
Mounting
Piping
• 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.
• 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 aect the flow.
• The inlet and discharge pipe/connections must correspond with the design
specifications of the pump as it may directly aect the eciency 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.
01. Remove the priming screw located on top of the pump.
02. 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).
03. Put the priming screw back in place. Ensure that there are no leaks.
02 03
OPERATING INSTRUCTIONS
SETTINGS
01. Ensure that the power supply cable is connected correctly.
02. 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.
03. 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.
IMPORTANT: changing the default settings
is not recommended, as it enables the unit
to respond optimally to potentially harmful
system conditions.

02. 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
0and 1.5 bar. The default is set at 0.15 bar and is the pressure at which the pump will
switch o 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 eciency zone and most accurately mimics municipal pressure supply
conditions.
02.4 B04 and B05:
• “180” Dry run - DO NOT CHANGE THIS SETTING.
01. 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.
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.

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 sucient
spacing (min. 100mm) between a surface and the
motor fan to allow for sucient cooling.
• Ensure the motor is has sucient ventilation.
E08 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.
E09 Variable

TROUBLE SHOOTING GUIDE
JOJO PUMP WARRANTY
Please read this warranty in conjunction with the South African Consumer Protection Act 68 of 2008.
01. JoJo warrants its pumps to the original end user/purchaser to be free of defective materials and workmanship
under normal use for a period of 12-months from the date of purchase from authorised retailers and distributors.
To be eligible for warranty repair or replacement, the pump must be returned to the point of purchase during
and up to the expiry date of the warranty period. Proof of date of purchase is required.
02. Liability in terms of this warranty shall be limited to repair or replacement of the pump. Liability for all and any
other losses and/or subsequent damages suered are expressly excluded.
03. This warranty does not obligate JoJo to bear any cost of removal, installation, transportation, or other charges
which may arise in connection with a warranty claim.
03. 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.
