Application
Onga 1000 Series pumps are suitable for pumping clean water in a
domestic water system, small irrigation applications, and general water
transfer. The Onga 1000 Series Jet-Asssisted pumps are fantastic at self-
priming, easy to install, and come in a wide range of packages to suit
almost any application.

Installation
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.
The pump is electrically connected. Ensure that it is isolated
from electrical supply during installation and any subsequent
service work.
The pump is designed to be used with clean water in a residential
application. Do not use it with alternative fluids, 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 for
heat damage during operation.
Read the following instructions in this owner’s manual when installing and
operating equipment.

1. Preparation for Installation
Inspect your pump for shipping damage. Report any damage to your Onga
Dealer. Make sure the suction piping is free of air leaks and is laid so that
there can be no airlocks.
Warranty of these pumps is void unless they are operated in accordance with
this owner’s manual.
2. Pump Protection
The pump should be protected from the weather, floods, chemicals, dust,
vermin, insects etc. It is highly recommended that the pump be housed in a
weather proof, well vented enclosure. If the pump is not adequately housed
the warranty may be deemed void.
Connection with a mains Pressure Hot Water System
The maximum pump pressure specification is 600kPa. It
is important that a reliable pressure relief valve (set to the
maximimum specification or lower) is installed between the pump
control discharge and the mains pressure Hot Water Service.
Failure to install this device may lead to product damage not
covered by the manufacturers warranty.
3. Pipe Installation
Pumps can be damaged if care is not taken when connecting pipes. Pipes
should be supported so that the pump casing is not strained by the weight
or misalignment.
We recommend the pump and pipe are coupled using flexible type polythene
pipe, rubber hose or a multi-directional barrel union. This union coupling can
also be used to remove the pump for service should it be necessary without
having to cut pipes.
Pipe fittings should be carefully screwed onto the pump making sure not to
cross-thread or overtighten. We recommend the use of a moulded pipe fitting
to connect to the pump as this avoids possible damage to the pump threads
and unnecessary replacement of parts.
For best results use teflon tape to join seal joint. Satisfactory sealing can be
achieved by hand tightening fittings ensuring that no leaks are evident once
under pumping pressure.
4. Locating the Pump
Find a location for your pump as close to your water source as possible.
IMPORTANT

Ensure that this location is on a seperate footing from your home. To do this
you can mount the pump on a concrete tile or concrete base.
5. Power Source
Arrange for an electrician to install an outdoor 10A GPO electrical outlet near
the pump if there is not one there already.
6. Suction
This is the most important part of the installation as errors will cause significant
problems for the system in performance and longevity.
IMPORTANT: A gate valve must be installed at the tank outlets.

To maintain optimum performance from your pump, the suction pipe should
be:
- Kept to the shortest distance practical, but not shorter than
the recommended length.
- Re-enforced crush resistant (non-collapsable) hose or pipe.
- All fittings should be air tight.
- Pipes should be equal to or larger than the diameter of the
suction/inlet port.
- Optional: Fitted with a suction Strainer/Filter
In-line strainers/filters are only recommended for pumps fitted with Minipress
or PressControl. Regular maintenance is required to keep them clean and
provide maximum pump pressure.
7. 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 pipework should be supported independently of the pump.
Connect the fitting at the top of the pressure controller (1”BSP Male) to the
household plumbing or garden taps*.
*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 pressure controller.
8. 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 tank. 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.
(Note: If a check valve is installed in the suction line, water may not fill the
pump. If this occurs, follow the instructions below).
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.

9. Electical Installation
The pump is supplied with a interconnection appliance coupler and standard
Australian 10 Ampere plug and cord. Connection to the power supply is a
matter of inserting the plug into the suitable socket outlet. Before plugging
the power supply cord into the socket outlet, connect the pump to it using the
provided IEC appliance connectors on the end of the interconnection cords.
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 a 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.
We recommend, for additional protection, the
pump to be supplied from socket 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.
WARNING
Hazardous voltage.
Can shock, burn, or
cause death.

Operation
The pump operator or owner must be provided with this owner’s
manual. This must be read before operation, and followed during
operation.
Ensure that your pump is filled with water before operating.
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.
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 for
heat damage during operation.
DO NOT RUN PUMP DRY
Ensure that your pump is filled with water before operating
1. Start-up / Operation
Priming
Prime the pump through the top priming plug port or outlet so that the pump
and suction line are full. Discharge pipework attached, turn pump on and
allow to operate until primed and all air is flushed out of suction and discharge
lines.
JMM, JSM & JSP Models only
When the power is turned on, the pump will start, and stop as soon as it has
pressurised the system it is connected to. If the pump does not start, press
11

the ‘restart’ button on the front of the pressure controller. Open a tap, (or
garden hose nozzle) and the pump should start and deliver water. When the
tap is closed, the pump will stop once pressure is built up in the system. The
system is now working correctly.
If no water is delivered, check the troubleshooting section on Page 14 of
this manual, and additionally, refer to the pressure controller installation and
operating instructions packaged with the controller.
JSK Models only
2. Pressure Switch
The Pressure Switch should be screwed onto the 3/4” port on the 5 way tee.
No sealing tape should be necessary and the locknut should only be just
over handtight to seal.
All pressure switches are factory set and will suit most domestic requirements
but may require further adjustment accordingly to individual installations.
3. Aqua Packs
Aqua Packs must be charged with air before installation. The air pressure used
should be 10% lower than the pressure switch cut-in setting of the pump, (e.g.
a pump working on 20-40 psi should have a tank air charge of 18 psi.)
Aqua Packs should be installed under cover, out of the weather, and the air
pressure should be regularly maintained.
4. Aqua Pack Tank Recharge Procedure
The air charge should be checked at least once a year as tanks gradually lose
air which causes pump cycling and pressure switch setting problems.
To check air pressure, turn off the electricity to the pump. Turn off the gate
valve from the water supply. Turn on a tap so that the water is drained from the
pump. Only then, measure the air pressure in the tank using a tyre pressure
gauge on the valve. If the pressure is low, recharge using a tyre pump. Do not
over charge the tank with air as this will cause tank liner damage, pressure
surge problems and/or the system to malfunction.
False readings can be obtained when checking the air pressure unless the
pressure tank is completely empty of water. If in doubt, turn off water supply,
drain discharge line and then disconnect the tank from the pipe work. When
the air pressure is correct, re-install the tank, open gate valve from the supply
tank and turn on the electricity. The pump should now operate normally once
any air is purged from the lines.

13
Service and Maintenance
Pump should only be serviced by qualified personel. For best
results, use only genuine service 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.
Liquid may be HOT, release pressure with care before
servicing.
1. General Care and Maintenance
No lubrication or regular maintenance is needed beyond reasonable care.
When pump is not in use for a long period of time, empty the pump, rinse it
with clean water and place it in dry storage.
In order to prevent possible failures, it is advisable to periodically check the
pressure supplied and power absorption. A decrease in pressure is a symptom
of wear. An increase current absorption is a sign of abnormal mechanical
function in the pump and/or motor.
