READ AND FOLLOW SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see this
symbol on your pump or in this manual, look for one of the
following signal words and be alert to the potential for
personal injury:
DANGER warns about hazards that will cause serious
personal injury, death or major property damage if ignored.
WARNING warns about hazards that can cause serious
personal injury, death or major property damage if ignored.
CAUTION warns about hazards that will or can cause
minor personal injury or property damage if ignored.
The label NOTICE indicates special instructions which are
important but not related to hazards.
Carefully read and follow all safety instructions in
this manual.
Electrical Safety
Wire motor for correct
voltage. See
‘Electrical’ section of
this manual and
motor label.
Ground motor before
connecting to power
supply.
Meet National or local
electrical code for all
wiring.
Do not touch an operating motor. Modern motors
are designed to operate at high temperatures. To
avoid burns when servicing pump, allow it to cool
for at least 20 minutes after shut-down before
handling.
General Safety
To avoid heat build-up, over pressure hazard and
possible injury, do not use in a pressure tank
(domestic water) system. Do not use as a booster
pump; pressurised suction may cause pump body to
explode.
Do not allow pump or piping system to freeze.
Freezing can damage pump and pipe, may lead to
injury from equipment failure and will void warranty.
Pump water only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on
pumps.

a) Preparation for operation
Read these instructions first
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
it rises evenly from water source to pump. This makes priming easier and
avoids airlock.
b) Pump Protection
Warranty of these pumps is void unless they are housed correctly and protected
from weather, floods, chemicals, dust, vermin, insects etc. Housing used should
be weather proof and well vented so that motor heat can escape. To obtain best
performanceopumps should be installed as close to water as possible.
Depending on application they do not have to be bolted down.
c) Pump Mounting
The pump must be mounted on a solid, level, vibration free surface.
Moulded pumps can be damaged by connected piping. Pipe should be supported
so the pump casing is not strained by the pipe weight or misalignment.
This appliance is not intended for use by young children or infirm persons
without supervision. Children should be supervised at all times when near this
appliance.

Reduction of Capacity with Centrifugal Pump Suction
Please note. Reduction of capacity affects both flow and pressure.
d) Suction
Suction should be laid so that it rises evenly from water source to pump. This
makes priming easy and avoids airlocks.
Pipes should be the same size or larger than the pump inlet and discharge
threads. If piping is longer than 15m (50ft) then a pipe fiction table should be
consulted to obtain the correct size.
All pipe joints must be sealed to ensure they are airtight and a foot or check
valve must be used in the suction pipe. If using a check valve make sure that
it is installed in correct direction.
e) Discharge
The length and diameter of the discharge hoses or pipe will effect 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.

ELECTRICAL
Disconnect power to motor before working on
pump or motor.
Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe
or fatal electrical shock hazard.
Do not ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn
OFF power to motor before working on electrical
connections.
Supply voltage must be no lower than 6% or no
higher than 10% of motor label voltage. Incorrect
voltage can cause fire or damage motor and voids
warranty. If in doubt consult a licensed electrician.
If possible, connect pump to a separate branch
circuit with no other appliances on it.
An earth leakage or residual current protection
device must be fitted to all installations, rated
residual operating current not exceeding 30mA.
A voltage surge protector should be fitted as
voltage spikes or incorrect voltage can cause fire
or seriously damage the motor.
Install, ground and maintain this pump in accordance with electrical code require-
ments. Consult your local building inspector for information about codes.
Provide a correctly fused Residual Current Device or Earth Leakage Device for
protection while working on motor. Consult local or national electrical codes for
switch requirements.
Disconnect power before servicing motor or pump. If the RCD or Earth Leakage
device is out of sight of the pump, lock it open and tag it to prevent unexpected
power application.

are made to any component.
power lead, it must be replaced with the appropriate s
Protect current carrying and grounding conductors from cuts, grease, heat, oil,
and chemicals.
Motor has automatic internal thermal overload protection. If motor has stopped
for unknown reasons, thermal overload may restart motor unexpectedly, which
could cause injury or property damage. Disconnect power before servicing motor.
If any of the preceding is confusing, consult a licensed electrician.
Make ground connection to green grounding terminal under capacitor cover lid
marked and/or E.
230 volt single phase motors are supplied as standard with on winding thermal
overload protection and are designed to plug directly into a 10 amp (GPO)
domestic power supply to local electrical authority specifications.
OPERATION
Priming the Pump (Suction lift installations)
NOTICE: ‘Priming’ refers to the pump expelling all air in the system and
beginning to move water from its source out into the system. It does not
refer only to pouring water into the pump (although pouring water in is usually
the first step).
NOTICE: NEVER run pump dry. Running pump without water in it will
damage seals and can melt impeller, diffuser and seal plate. To prevent damage,
fill pump with water before starting.
1. Remove priming plug (located on top of the pump casing).
2. Make sure discharge valve(s) and any hoses on discharge side of the
pump are open.
3. Fill pump and suction pipe with water.
8
OPERATION (continued)
4. Replace priming plug, using Teflon tape on thread; tighten plug.
NOTICE: If a priming tee and plug have been provided for a long
horizontal run, be sure to fill suction pipe through this tee and replace
plug. (Don’t forget to Teflon tape the plug.)
5. Start pump: water should be produced in 10 minutes or less, the time
depending on depth to water (suction lift not more than 6 metres) and
length of horizontal run.
If no water is produced within 10 minutes, stop pump, release all pressure,
remove priming plug, refill and try again.
Hazardous pressure and risk of explosion and scalding. If pump is
run continuously at no flow (that is, with discharge shut off or with-
out priming), water may boil in pump and piping system. Under steam
pressure, pipes may rupture, blow off fittings or blow out of pump
ports and scald anyone near.
To prevent explosion, do the following:
A. Ensure discharge (valve, hose nozzle, etc.) is open whenever pump is
running.
B. If pump fails to produce water when attempting to prime, release all
pressure, drain pump and refill with cold water after every two
attempts.
C. When priming, monitor pump and piping temperature. If pump or piping
begin to feel warm to the touch, shut off pump and allow system to
cool. Release all pressure in system and refill pump and piping with cold
water.

SERVICE & MAINTENANCE
This centrifugal pump requires little or no regular service
other than reasonable care and periodic cleaning. Occasion-
ally, however, a shaft seal may become damaged and must be
replaced. The procedure as outlined below will enable you to
replace the seal.
NOTICE: The highly polished and lapped faces of the seal are
easily damaged. Read instructions and handle the seal with
care.
REMOVAL OF OLD SEAL
1. After unscrewing impeller, carefully remove rotating part of seal by
prying up on sealing washer, using two screwdrivers (see Figure A).
Use care not to scratch motor shaft.
2. Remove seal plate (baffle) from motor and place on flat surface, face
down. Use a screwdriver to push ceramic seat out from seal cavity (see
Figure B).
INSTALLATION OF FLOATING SEAL
(Figure C)
1. Clean polished surface of floating (ceramic) seat with clean cloth.
2. Turn seal plate over so seal cavity is up; clean cavity thoroughly.
3. Lubricate outside rubber surface of ceramic seat with silicone based
lubricant, ensuring no lubricant gets on the polished ceramic wear face,
and press firmly into seal cavity with finger pressure. If seat will not
locate properly in this manner, place a cardboard washer over polished
face of seal and press into seal cavity using a socket or 13mm
piece of standard pipe. ½” 13mm
Liquid may be HOT, release pressure before servicing.
½” 13mm socket
or 13mm pipe

Liquid may be HOT, release pressure before servicing.
Pump should only be serviced by qualified personnel. Make sure to
prime pump before operating. NEVER run pump dry!
If the supply cord is damaged, it must be replaced by the
manufacturer or an authorised service agent.
SERVICE & MAINTENANCE (continued)
4. Dispose of cardboard washer. If need ensure polished surface of seal
seat is free of dirt and has not been damaged during insertion. Remove
any excess lubricant that may have been dislodged during insertion and
ensure that there is no lubricant on the polished face of the seal.
INSTALLATION OF ROTATING PART OF SEAL UNIT
(Figure D)
2. Reinstall seal plate using extreme caution not to hit ceramic portion of
seal on motor shaft.
3. Inspect shaft to ensure that it is clean.
1. Clean face of sealing washer with clean cloth.
4. Lubricate outer face of rubber drive ring with silicone-based lubricant,
ensuring no lubricant touches the polished face, and slide assembly on
motor shaft (sealing/polished face first) until rubber drive ring hits shaft
shoulder (ensure that the polished face does not hit the motor shaft).
5. Screw impeller on shaft until impeller hub hits shaft shoulder. This will
automatically locate seal in place and move the sealing washer face up
against the facing seat.
Should you have any difficulty replacing the seal unit please contact your local
pump professional.
