(Have a trained pool professional perform all pressure tests).
Before pressure testing, make the following safety checks:
1. Check all clamps, bolts, lids, and system accessories prior to testing.
2. Release all air in system before testing.
3. Tighten trap lid to 4.1kg-m torque for testing.
4. Water pressure for test must be less than 170kPa (25 PSI)
5. Water tempertaure for test must be less than 38°C
6. Limit test to 24 hours. After test, visually check system to be sure it is ready
for operation. Remove trap lid and retighten hand tight only.
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 from heat damage during operation.
Only qualifi ed, licensed personnel should install pump. The electrical
installation shall be in accordance with the national wiring rules (AS/NZS 3000)
for class I, IP55 rated products. Refer to page 10 for Electrical Installation.
Pressure Testing
L300216_SilentFlo_OM_2012
Monday, 17 December 2012 1:32:22 PM

Pump mount must:
1. Be located away from corrosive or flammable chemicals. Have enough ventilation to
maintain air tempertaure at less than the maximum ambient temperture rating. If this
pump is installed in an enclosure/pump house, the enclosure must have adequate
ventilation (200sq.cm min, inlet & outlet) and air circulation to keep the temperature
in the enclosure at or below the motor’s rated ambient temperature whenever the
pump is running. Keep rear of motor clear (150mm).
2. Be solid, level, rigid and ribration free. (To reduce vibration and pipe stress, bolt pump
to mount). Fixing holes accept 12mm fasteners.
3. Allow pump suction inlet height to be as far below water level as possible.
4. Allow use of short, direct suction pipe (to reduce friction losses).
5. Allow for shut-off valves in suction and discharge piping.
6. Have adequate floor drainage to prevent fl ooding.
7. Be protected from excess moisture
8. Allow adequate access for servicing pump and piping.
We recommend mounting the pump on a concrete platform for quietest performance.
Use Tefl on tape for making all threaded connections to the
pump. DO NOT use pipe dope (glue) as this will cause stress
fractures in the pump.
Pump suction and discharge connections have moulded in
thread stops. DO NOT screw pipe in beyond these stops.
DO NOT use sealants which are incompatible with pipe fi ttings.

ttings.
 Wrap male pipe threads with a sufficient number of layers of Tefl on tape.
Cover entire thread portion.
 Do not overtighten or tighten past thread stop in pump port.
 If leaks occur, remove pipe, clean off old tape, wrap as previously with one
to two additional layers of tape and remake the connection.
Piping
Support all piping connected to the pump.
 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 connections (2”/50mm).
 To avoid airlocking, slope suction pipe slightly upward toward the pump.
 Do not use an elbow near the suction port of the pump. Use a straight length of
pipe into the suction port.
To prevent flooding when removing pump for service, all fl ooded suction
systems must have shut-off valves in suction and discharge pipes.
Fittings
Teflon Taping Instructions
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 standard.

Pump suctions are hazardous and can trap and drown or disembowel bathers.
Do not use or operate pump, pool or spa if a suction outlet cover is missing,
broken, or loose. Follow the guidelines below for a pump installation which
minimises risk to users or pools and spas.
Entrapment Protection
The pump suction system must provide protection against hazard of suction
entrapment or hair entrapment/entanglement.
Testing and Certif
ication
Suction outlet covers must have been tested by a nationally recognised
testing laboratory and found to comply with the latest AS1926.3 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 centres of the main drains (suction
fittings) must be at least 800mm apart.
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 shut off 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.
Water Velocity
The maximum water velocity through any suction outlet must comply with
the latest AS1926.3 Standard or ASME/ANSI Specification for Suction
Fittings For Use in Swimming Pools, Spas, Hot Tubs, and Whirlpool Bathtub
Applications.

WARNING
Electrical
Electrical installation shall be in accordance with the national wiring rules (AS/NZS
3000) taking into account its ratings (Class I, IPX5). The pump is supplied with a
standard Australian 10 amp plug and 2 metres of cord. Select the correct Pool Zone
for installation.
Using the tapped hole terminal and tin plated copper lug connect the equipotential
bonding conductor to the pump if required. The terminal is on the motor side of the
fl ange. Remove paint from the terminal surface and use M5x12 zinc plated screw with
lock washer or similar to secure the termination.
An RCD with maximum rated residual current of 30mA is required for the power supply
to the pump. Additionally, if a suitable socket outlet is not available a weatherproof
socket must be installed by an electrician in a suitable location. RCD tripping indicates
an electrical problem. If RCD trips and will not reset have a qualifi ed electrician inspect
and repair electrical system.
Do not use extension leads as they are unsafe in and around the Pool Zone.
Incorrect voltage can cause fire or seriously damage pump and voids warranty.
Voltage at pump must not be more than 6% above or
10% below motor nameplate rated voltage or pump
may overheat, causing overload tripping and reduced
component life. If voltage is less than 90% or more than
106% of rated voltage when pump is running at full load,
consult the power company.
To avoid dangerous or fatal electrical shock, turn OFF
power to pump and remove plug from outlet before
working on electrical connections.
The power supply cord has a type ‘Y’ attachment and if
service is required to the power cord, it must be replaced
with the specialised power cord assembly by Pentair
Water service agent or similarly qualifi ed personnel in
order to avoid a hazard. Warranty is void if unauthorised
modifications are made to any component.

The pump operator or owner must be provided with this owner’s
9
manual. This must be read before operation, and followed during
operation.
The pump is not intended for use by young children or infi rm persons
without supervision. Young children should be supervised to ensure
that they do not play with the pump.
NEVER run pump dry. Running pump dry may damage seals, causing
leakage and flooding. Fill pump with water before starting motor.
If pump has been pressure tested, ensure pressure has been released
before removing trap lid. Do not block pump suction. To do so with
body may cause severe or fatal injury.
Small children using pool must ALWAYS have close adult supervision.
Pump suction is hazardous and can trap and drown or disembowel
bathers. Do not use or operate pump, pool/spas if a suction outlet
cover is missing, broken, or loose. Follow the guidelines below for a
pump installation which minimises risk to users of pool and spas.
Fire and burn hazard. Modern motors run at high temperatures. To
reduce the 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.
Before removing trap lid:
1. SWITCH OFF POWER SUPPLY to pump and unplug from outlet
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 trap lid while pump is operating.

An automatic internal thermal overload switch protects the
motor from heat damage during operation and if operated
can restart without notice.
Maximum ambient temperature for motor operation must not
exceed maximum ambient temperature range (See page 4).
Switch the pump off at the controller or power point while
ambient temperature exceeds maximum.
Priming Pump
Release all air from fi
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 follow
above instructions for removing trap lid; fill trap and pump with water.
Do not lubricate the trap lid o-ring. The original equipment O’ring contains a permanent
internal lubricant.
If the o-ring needs replacement insist on genuine Onga service parts. Clean and
inspect o-ring; reinstall on trap. Replace trap lid turn clockwise to tighten by hand only
- no wrenches!
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 3 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 20°C, and 50Hz mains power supply.
Should the pump not prime, ensure that all valves are open, lint trap is clear of debris
and suctions and suction pipe end is submersed in water, and that there are no leaks in
suction pipe. See troubleshooting guide.

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.
Routine Maintenance requires regular checking of the pump to ensure no water is
leaking from joints whilst pump is operating and inspection/cleaning of trap basket.
Debris or trash that collects in basket will choke off water fl ow through the pump.
Do not operate pump with trap basket missing or damaged.
Follow instructions below to clean trap:
1. Switch off power to pump, close valves in suction and discharge, and release all
pressure from system before proceeding.
2. Remove trap cover (turn clockwise). If necessary, tap handles gently with a rubber
mallet or use a board as a lever.
3. Remove strainer basket and clean. Ensure all holes in basket are clear, fl ush basket
with water and replace in trap with large opening at pipe connection port (between
ribs provided). If basket is replaced backwards, the cover will not fit on trap body.
To clean tranparent cover, use water and neutral soap only. Do not use solvents.
4. Clean and inspect lid o-ring; reinstall on trap.
5. Clean O’ring groove on trap body and replace cover. To help keep cover from
sticking, tighten hand tight only.
6. Prime pump (refer priming instructions).
Pump Service
Pump should only be serviced by qualifi
genuine Onga service 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 covers, valves, nuts or bolts while pump is

No lubrication or regular maintenance is needed beyond reasonable care and periodic
cleaning of strainer basket. When pump is not in use and there is a risk of frost, empty
it completely through the drain plug. If shaft seal is worn or damaged consult your
Pentair Water authorised service agent.
Symptom Cause Remedy
Low water pressure, low f ow
from pump.
Suction leaks / lost prime. 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 suctions 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.
Low voltage. Check voltage at motor terminals
and at meter while pump is
running - this check should
be performed by a qualif ed
electrician only. If voltage is low
check for loose connections or
consult your power company.
Clogged pipe / strainer /
impeller / f ilter system.
Ensure trap is not clogged with
debris; clean basket and/or f ilter.
Make sure that the impeller is not
clogged. This should be checked
by qualif ied personnel only.
Pump may be trying to push too
high a column of water. If so, a
