Relax - you’ve bought an onga ...
Congratulations on your decision to purchase an onga
product. onga is one of the best known companies in its
field, with a proud local and international reputation.
In fact, wherever people need to move water from one point to
another - whether in industry, horticulture, agriculture or in and
around the home - onga is a byword for reliability, value for money
and technological innovation. So why does onga lead its field?
Here are a few simple reasons ...
1. Continual Product Improvement
onga employ the best engineers both in Australia and around the
world to develop new and better ways to pump and handle water.
2. Dedication to Quality
There is only one standard that we at onga set ourselves for both
product quality and the quality of our service. That standard is
excellence ... to have no-one better than us at what we do ... nothing
short of that is acceptable.
3. A Fair Price
onga pumps are neither the cheapest nor the most expensive in their
field. Our products do, on the other hand, always represent very
good value for money - they always have and they always will.
4. Our Team of Dealers
We believe onga’s hand picked authorised dealer network -
throughout Australia and worldwide - are second to none. We in
vest a huge sum training them and supporting them. They are your
link to us, and we value their expertise and trust.

OPERATING INSTRUCTIONS
Please read these instructions in full before installing and commission-
ing the pump unit.
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 engine
heat and exhaust fumes can escape. To obtain best possible perform-
ance, pumps should be installed as close to water as possible.
Suction and Discharge Pipes
Suction pipe should be laid so that it rises evenly from water source to
pump. This makes priming easy and avoids airlocks.
Hoses should be the same size as the pump inlet and/or larger than the
discharge port.
All pipe joints must be sealed to ensure they are airtight.
Priming
To prime pump, remove priming plug and fill pump and suction pipe
with water. Pump is equipped with suction flap valve and should be
capable of drawing air out of normal size suction pipes or hoses. Re-
place plug and start the pump. If the pump pumps a little and stops,
turn the pump off, check suction pipe for possible leaks and repeat
priming procedure until the pump operates satisfactorily.
Self priming pumps, when filled with water, will gradually draw air out
of the suction line (depending on model) to a maximum vertical lift of
6 metres (20 ft). If priming a long or large diameter pipe, additional
water may have to be added to the pump at 3 minute intervals.

Suction Limitations
Theoretically, no pump can lift water higher than 9 metres (30 ft) verti-
cally, and the practical limit is approximately 6 metres (20 ft), depend-
ing on the installation.
The pump is equipped with an internal suction flap valve. If pump fails
to prime, it could be due to a leak in the suction pipe, a worn impeller
or too great a suction lift. Self priming pumps do not self prime when
subject to a high discharge head. Under these conditions the suction
flap valve should be removed and a foot valve installed on the end of
the suction line.
Suction Strainer
For portable pump use, a suction hose strainer must be used. This
removes the risk of gravel or large pieces of foreign matter entering and
damaging the pump.
Type of Water
Pumps are capable of pumping septic tank effluent, sink wastes, small
amounts of dirt or sand, drainage or polluted water and some industrial
wastes. They are not designed to pump large quantities of foreign mat-
ter. If fluid contains large or stringy material, then an adequate suction
strainer should be used.
If chemicals are to be pumped, compatability of pump material should
be checked with your local onga office.
SERVICE
Pump runs but fails to pump water:
1) Check for an air leak in suction pipe.
2) The pump has not been filled with water.
3) Water has evaporated leaving pump dry.
4) Foreign matter has clogged the impeller or pipe.
5) Suction lift too high.

Engine
See instructions supplied by engine manufacturer. Be sure to initially
put oil in engine and check level regularly. Low speeds extend engine
life dramatically. We recommend for continuous pumping that the pump
be operated at approximately 3000 r.p.m.
Be aware that unstable mounting practices may be hazardous to the
and/or property.
