Installation (Continued)
NOTICE: If the pump is not provided with a supply cord and a plug, or with
other means of disconnection from the supply having a contact separation of
at least 3mm in all poles, such means for disconnection must be incorporated
in the fixed wiring.
NOTICE: Use Teflon tape for making all threaded connections to the pump.
Do not use pipe dope (glue) as this will cause stress fractures in the pump.
NOTICE: Pump suction and discharge connections have moulded in thread
stops. DO NOT screw pipe in beyond these stops.
Teflon Taping Instructions:
Use only new or clean PVC pipe fittings.
Wrap male pipe threads with one to two layers (or a sufficient number of
layers) of Teflon tape. Cover entire threaded portion.
Do not overtighten or tighten past thread stop in pump port.
If leaks occur, remove pipe, clean off old tape, rewrap as previously with one
to two additional layers of tape and remake the connection.
NOTICE: Support all piping connected with pump.
Piping:
Use at least 2” (50mm) PVC pipe. Increase size if a long run is needed.
To avoid stress on the pump, support both suction and discharge pipes
independently. Place these supports as close to the pump as possible.
To avoid a strain left by a gap at the last connection, start all piping at the
pump and run pipe away from the pump.
Never use a suction pipe smaller than pump suction connection (2”/50mm).
To avoid airlocking, slope suction pipe slightly upward toward the pump.
NOTICE: To prevent flooding when removing pump for service, all flooded
suction systems must have shut-off valves in suction and discharge pipes.
Fittings:
Fittings restrict flow; for best efficiency use fewest possible fittings.
Avoid fittings which could cause an air trap.
Pool outlets:
Use only non-entrapping suction fitting or double suction conforming with the
AS1926.3-2003 Standard.

Pool Pump Suction Requirements
Pump suction is hazardous and can trap and drown or disembowel
bathers. Do not use or operate swimming pools, spas, or hot tubs if
a suction outlet cover is missing, broken, or loose. Follow the guidelines
below for a pump installation which minimises risk to users of pools, spas, and
hot tubs.
Entrapment Protection
The pump suction system must provide protection against the hazard of
suction entrapment or hair entrapment/entanglement.
Suction Outlet Covers
All suction outlet covers must be maintained. They must be replaced if
cracked, broken, or missing.
See below for outlet cover certification requirements.
All suction outlets must have correctly installed, screw-fastened covers in
place.
Testing and Certification
Suction outlet covers must have been tested by a nationally recognised
testing laboratory and found to comply with the latest AS1926.3-2003
Standard or ASME/ANSI Specification for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications.
Outlets Per Pump
Provide at least two hydraulically balanced main drains, with covers, for each
swimming pool pump suction line. The centers of the main drains (suction
fittings) must be at least 800mm apart.
Troubleshooting Guide (Continued)
Symptom
Cause
Air ingress to system.
Remedy
Prime the pump. Check that
there are no air leaks in the
suction piping or fittings.
Ensure the strainer lid is
airtight and fitted securely.
Check that there are no leaks
coming from beneath the
pump.
Pump running too slowly.
Low voltage.
Check voltage at motor
terminals and at meter while
pump is running – this check
should be performed by a
qualified electrician only. If
voltage is low check for
loose connections or consult
your power company.
Pump may be too hot.
Check line voltage; if less
than 90% or more than
110% of rated voltage
consult a licensed
electrician.
Increase ventilation. Reduce
ambient temperature.
Tighten any loose
connections.

o’ring before retightening the
bolts. Replace the o’ring if
leaking persists.
Replace the mechanical seal.
Should problems persist, contact your nearest Onga service agent.
The system must be built so that it cannot operate with the pump drawing
water from only one main drain (that is, there must be at least two main drains
connected to the pump whenever it is running). However, if two main drains
run into a single suction line, the single suction line may be equipped with a
valve which will shutoff both main drains from the pump.
More than one pump can be connected to a single suction line as long as the
requirements above are met.

Troubleshooting Guide
Symptom
Pump failure or reduced
capacity or reduced
discharge pressure.
Cause
Suction leaks / lost prime
Clogged pipe / strainer /
impeller, worn impeller.
No power at outlet.
Blown fuse.
Motor burnt out due to
voltage spike or flooded by
water.
Valves turned to the closed
position.
16
Remedy
Pump must be primed; make
sure that the pump casing
and strainer are full of water.
Refer priming instructions.
Make sure there are no leaks
in suction piping.
Make sure suction pipe inlet
is well below the water level
to prevent pump from
sucking air.
Suction lift of 3 to 6 metres
will reduce performance.
Suction lift of more than 6
metres will prevent pumping
and cause pump to lose
prime. In either instance,
move the pump closer
(vertically) to water source.
Ensure that the suction pipe
diameter is large enough.
Ensure trap is not clogged
with debris; if it is, clean
strainer & basket.
Make sure that the impeller
is not clogged. This should
be checked by qualified
personnel only.
Impeller and diffuser may be
worn. If so, check with your
local Onga dealer or suitably
qualified personnel.
Pump may be trying to push
too high a column of water. If
so, a “higher head” pump is
required.
Use another electrical
appliance that is known to
work to check the power
outlet.
Check fuse and replace if
necessary.
The motor may need
replacing.
Water Velocity
The maximum water velocity through any suction outlet must be 1.8 metres
per second or less unless the outlet complies with the latest AS1926.3-2003
Standard or ASME/ANSI Specification for Suction Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub Applications. In any
case, do not exceed the suction fittings maximum designed flow rate.
If 100% of the pump’s flow comes from the main drain system, the maximum
water velocity in the pump suction hydraulic system must be 1.8 metres per
second or less even if one main drain (suction fitting) is completely blocked.
The flow through the remaining main drain(s) must comply with the latest
AS1926.3-2003 Standard or ASME/ANSI Specification for Suction Fittings
For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub
Applications.
Check the plumbing to
ensure the valves are in the
correct position for pumping
on the suction and
discharge.

Ground motor before connecting to electrical power
supply. Failure to ground motor can cause severe or
fatal electrical shock hazard.
1.
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.
Residual Current Device (RCD) tripping indicates an
electrical problem. If RCD trips and will not reset,
have a qualified electrician inspect and repair
electrical system. Onga recommends that a RCD of
30mA trip current be installed and/or be in
compliance with local regulations.
Exactly match supply voltage to motor nameplate
voltage. Incorrect voltage can cause fire or seriously
damage motor and voids warranty. If in doubt
consult a licensed electrician.
The power supply lead has a type “Y” connector and
if service is required to the power lead, it must be
replaced with the appropriate specialised power lead
assembly. Warranty is void if unauthorised
modifications are made to any component.
Voltage
Voltage at motor must not be more than 10% above or below motor
nameplate rated voltage or motor may overheat, causing overload tripping and
reduced component life. If voltage is less than 90% or more than 110% of
rated voltage when motor is running at full load, consult power company.

Operation (Continued)
Operation (Continued)
Priming Pump
Release all air from filter, pump and piping system: refer filter owner’s manual.
In a flooded suction system (water source higher than pump), pump will prime
itself when suction and discharge valves are opened.
If pump is not in a flooded suction system, disconnect power supply to pump
and remove trap cover handle ring and trap cover; fill trap and pump with
water.
Do not lubricate the trap cover O’ring. The original equipment O’ring contains
a permanent internal lubricant.
Routine Maintenance
The only routine maintenance required is inspection/cleaning of trap basket.
Debris or trash that collects in basket will choke off water flow through the
pump. Follow instructions below to clean trap:
1.
2.
3.
NOTICE: If you replace the O’ring with a non-internally lubricated O’ring, you
may need to apply a silicone based lubricant.
Clean and inspect O’ring; reinstall on trap.
Replace trap cover and handle ring on trap; turn handle ring clockwise to
tighten cover.
4.
5.
NOTICE: Tighten trap cover handle ring by hand only (no wrenches!)
6.
Pump should prime now. Priming time will depend on vertical height of suction
lift and horizontal length of suction piping. The self-priming time range is 1 to 5
minutes for a height difference of 2 to 3 metres, under normal installation
conditions. Normal conditions are understood to be: with suction having an
internal diameter of DN 50mm, water temperature at 20oC, and 50Hz mains
power supply.
Should the pump not prime, ensure that all valves are open, lint trap is clear of
debris and suction pipe end is submersed in water, and that there are no leaks
in suction pipe.
See Troubleshooting Guide.
Switch off power to pump, close valves in suction and discharge, and
release all pressure from system before proceeding.
Remove trap cover handle ring (turn counterclockwise). If necessary,
tap handles gently with a rubber mallet.
Remove strainer basket and clean. Ensure all holes in basket are clear,
flush basket with water and replace in trap with large opening at pipe
connection port (between ribs provided). If basket is replaced
backwards cover will not fit on trap body. To clean transparent cover,
use water and neutral soap only. Do not use solvents.
Clean and inspect lid o’ring; reinstall on trap.
Clean O’ring groove on trap body and replace cover and handle ring. To
help keep cover from sticking, tighten hand tight only.
Prime pump (refer priming instructions).
Pump Service
Pump should only be serviced by qualified personnel. For best
results, use only genuine Onga factory parts.Be sure to prime pump
before starting.
Before removing clamp or trap cover:
1.
SWITCH OFF POWER to pump before proceeding.
2.
CLOSE SHUT-OFF VALVES in suction and discharge pipes.
3.
RELEASE ALL PRESSURE from pump and piping system.
4.
NEVER tighten or loosen clamp while pump is operating!
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.
No lubrication or regular maintenance is needed beyond reasonable care and
