SILENTFLO™ Pool Pump
Owner’s Manual
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.
ELECTRICAL
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.
WARNING
Hazardous voltage.
Can shock, burn,
or cause death.
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 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 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.
OPERATION
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
flange. 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 qualified 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.
