These instructions are a guide only. Users not familiar with
pumping equipment should seek advice from people experienced
in pump equipment and installation.
The pump operator or owner must be provided with this owner’s
manual. This must be read before operation, and followed during
operation.
Freezing conditions will damage the unit, because as water
freezes it expands. Ensure that VF150 is located so that it is not
prone to freezing, or ensure that the product is disconnected and
dried of water during cold conditions.
VF150 is electrically connected. Ensure that it is isolated from
electrical supply during installation and any subsequent service
work.
VF150 is designed to be used with clean water in a residential
application. Do not use it with alternative fluids, specifically
abrasive, corrosive or explosive fluids. Do not install or operate
your VF150 in an explosive enviroment or near combustible
matter.
Do not run the OTB450A dry, or with the motor exposed (i.e. out
of the water) for long periods. This will harm the pumps seal, and
overheat the motor.
Do not lift/move/or carry this pump by the electrical or float
switch cables.
This appliance is not intended for use by persons (including
children) with reduced physical, sensory or mental capabilities,
or lack of experience and knowledge, unless they have been given
supervision or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do not play
with the appliance.
When used in a swimming pool the following applies:

Application
VF150 is designed for clean water or water containg some soft solids. Typical
applications include dewatering pits, drainage, water features and grey water.
Do not use your VF150 for liquids other than clean water. Using corrosive, abrasive
or explosive fluids will damage the unit, and may cause personal injury or death.

Fittings and accessories
Ensure that you have all required fittings and accessories prior to installing your VF150:
• threadseal tape (rigid discharge pipe installations)
• hose clamps (flexible discharge pipe installations)
• cable ties
A larger diameter hose or pipe will offer less resistance to flow, and so give better
performance.
Preparation for installation
Read these instructions first
Inspect your VF150 for shipping damage. Report any damage to your Pentair Water
dealer. Read the Owner’s Manual that was shipped with the pump to ensure correct pump
installation.
Securely connect a stainless steel wire cable or a rope to the handle of the pump ensuring
that the wire/cable exceeds the safe working load of 10kg.
If you are using a rigid discharge pipe, thread the fitting / pipework into the outlet of the
pump housing.
If you are using a flexible discharge hose, use hose clamps to secure this to the fitting
provided.
Lower the pump into the tank using the rope or wire cable. Lower the pump onto a hard
level surface that is elevated from the base of the pit. This is to keep the pump inlet above
sediments in the bottom of the tank.
Ensure that the float switch can move freely within the tank – incorrect operation and pump
failure may occur if the float switch becomes trapped.
The pump must only be connected to a socket that has been correctly installed in accordance
with national wiring regulations and is protected with a residual current device (RCD) with
a rated residual operating current not exceeding 30mA. The pump will operate when the
float is above the cut in level, and stop operating when the float is below the cut out position.
If the pump must be removed from the tank, use the lifting rope or lifting wire cable to lift
it. Do not use the power cable or the float switch to lift the pump.
Installation

9
Operation
Connect the pump to a suitable power outlet.
Operation Check
1. Ensure that the pump is completely submerged.
2. This may require that the tank has a little water fed
into it from another source.
3. The float switch will rise, and the pump will start, and empty the pit.
As the pit empties, the float switch will fall, and stop the pump.
4. Check that there is adequate pressure and flow from
the discharge point.
If there are any variations to these outcomes, please see the troubleshooting
section on the following page.

10
Symptom Cause Remedy
Pump doesn’t
start
Float switch isn’t in the
‘on’ position
Wait until there is more water in the
pit to start the pump
Not enough water in the
pit to get the float above
level
Float is caught on
something, and can’t rise
above level
Ensure that the float can move freely
No power supply Ensure that the pump is connected to
a live outlet
Check fuses and circuit breakers
Pump is blocked Disconnect the pump from the power
outlet, and check the pump housing
and discharge for foreign matter
No water from
pump
Blockages in the pump or
discharge
Disconnect the pump from the power
outlet, and check the pump housing
and discharge for foreign matter
Excessive lift Ensure that the height that you are
trying to lift water is within the pump’s
capacity. A larger pump may be
required.
Not enough water in the
pit to pump
Wait until there is more water in
the pit. Ensure that float switch is
operating freely
Pump will not
stop, even
though there is
little water in
the pit.
Float switch is trapped in
the “up” position
Ensure that the float switch can
operate freely
Float switch is fused “on” Replace the float switch
Trouble Shooting

11
Symptom Cause Remedy
Pump runs
intermittently:
Thermal
protection
inside the
pump is
tripping and
resetting
The pump is not
completely submerged
Ensure pump is covered with water
Water temperature is too
high
Ensure that water temperature limits
are observed.
Pump runs
intermittently
When the pump shuts off,
water in the discharge line
is running back into the
pit, lifting the float switch.
Fit a non-return valve at the pump
discharge so that water cannot return
to the pit

12
You should regularly inspect your Onga VF150 for any damage or deterioration
due to either fair wear and tear or misuse.
If the supply cord is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualified person in order to avoid a hazard.
It is recommended that you periodically check the pump’s pressure and current
draw. A decrease in pressure is a symptom of pump wear caused by grit or silt
in the water. An increase in current draw is a symptom of abnormal mechanical
friction in the pump or motor that is caused by solid material being lodged within
the pump. In the event either of these symptoms occur the pump must be serviced
by the manufacturer, its service agent or similarly qualified person in order to
avoid pump failure and/or a hazard.
Service & Maintenance
Pumping water containing solids will reduce the life of the pump,
and may affect warranty.
Pumping chemicals or agricultural products voids warranty.
Do not pump hydrocarbons with this pump.
If the pump is not going to be used for a long period of time, it
should be a completely emptied, rinsed with clean fresh water,
and stored in a dry place.
