INSTALLATION
CHAPTER 3
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 installa-
tion.
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 condi-
tions.
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 uids, abrasive, corrosive or explosive uids. 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 re, 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

CHAPTER 3
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, oods, chemicals, dust, vermin, insects etc. It is
highly recommended that the pump be housed in a weather proof, well vented enclosure. If the pump
Connection with a mains Pressure Hot Water System
The maximum pump pressure specication is 600kPa. It is important that a reliable pressure relief
valve (set to the maximimum specif cation 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 manufactu-
rers warranty.
IMPORTANT:
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 exible 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 ttings should be carefully screwed onto the pump making sure not to cross-thread or over-
tighten. We recommend the use of a moulded pipe tting to connect to the pump as this avoids
possible damage to the pump threads and unnecessary replacement of parts.
For best results use tef on tape to join seal joint. Satisfactory sealing can be achieved by hand tighte-
ning ttings 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.
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.

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 ttings 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/lters are only recommended for pumps tted with 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 ow 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 tting 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 ll 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 ll the pump body and suction
line. Remove the priming plug and ll 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 rmly 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 ood free location; preferably do not use extension cords for
this very reason and because they can cause voltage drop.
Supply voltage outside limits specied 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.

OPERATION
CHAPTER 4
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 lled with water before operating.
The pump is designed to be used with clean water in a residential application. Do
not use it with alternative uids, specically abrasive, corrosive or explosive uids.
Do not install or operate your pump in an explosive enviroment or near combusti-
ble matter.
Fire and burn hazard. Modern motors run at high temperatures. To reduce risk
of re, 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 lled with water before operating
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
ushed out of suction and discharge lines.
JS with PressControls 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 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 10 of this manual, and addi-
tionally, refer to the pressure controller installation and operating instructions packaged with the
controller.

EN INSTRUCTION MANUAL
JS with Pressure Switch only
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.
Aqua Pack Plus
Aqua Packs plus 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.
Aqua Pack Plus 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.

SERVICE AND MAINTENANCE
CHAPTER 5
Pump should only be serviced by qualied 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.
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.
