Application
Flotec AJ & MM Series pumps are suitable for pumping clean water in a
domestic water system, small irrigation applications, and as pressure booster
pumps. The strength of the stainless steel pump casing coupled with the
impervious nature of the technopolymer impeller and diffuser make it ideally
suited for most potable water pumping applications.

Installation
We strongly recommend this product be installed by a suitably
qualified person.
The electrical installation shall be in accordance with the national
wiring rules (AS/NZS 3000) for class 1, IPX4 rated products.
These instructions are a guide only. Users not familiar with pumping
equipment should seek advice from people experienced in pump
equipment and installation.
Freezing conditions will damage the unit, because when water
freezes it expands. Ensure that the pump is located so that it is not
prone to freezing, or ensure that the product is disconnected and
dried of water during cold conditions.
AJ & MM pumps are electrically connected. Ensure that they are
switched off and unplugged from socket outlet during installation
and any subsequent service work.
The pump is designed to be used with clean water in a residential
application. Do not use it with alternative fluids, abrasive, corrosive
or explosive fluids. Do not install or operate your pump in an
explosive environment or near combustible matter.
Incorrectly installed or tested equipment may fail, causing severe
injury or property damage.
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. Automatic thermal overload cut-out protects the motor for heat
damage during operation and it will restart without notice when the
motor cools down.
The pump is not intended for use by young children or infirm persons
without supervision. Young children should be supervised to ensure
that they do not play with the pump.
Read the following instructions in this owner’s manual when installing and operating
equipment.

1. Preparation for Installation
Inspect your pump for shipping damage. Report any damage to place of purchase.
We strongly recommend this product be installed by a suitably qualified person.
Make sure the suction piping is free of air leaks and is laid so that there can be
no airlocks.
Warranty of these pumps is void unless they are operated in accordance with
this owner’s manual.
2. Pump Protection
The pump should be protected from the weather, floods, chemicals, dust, vermin,
insects etc. It is highly recommended that the pump be housed in a weather
proof, well vented enclosure. If the pump is not adequately housed the warranty
may be deemed void.
3. Pipe Installation
Pumps can be damaged if care is not taken when connecting pipes. Pipes
should be supported so that the pump casing is not strained by the weight or
misalignment.
We recommend the pump and pipe are coupled using flexible type polythene
pipe, rubber hose or a multi-directional barrel union. This union coupling can
also be used to remove the pump for service should it be necessary without
having to cut pipes.
Pipe fittings should be carefully screwed onto the pump making sure not to
cross-thread or overtighten. We recommend the use of a moulded pipe fitting
to connect to the pump as this avoids possible damage to the pump threads and
unnecessary replacement of parts.
For best results use teflon tape to seal the joint. Satisfactory sealing can be
achieved by hand tightening fittings ensuring that no leaks are evident once
under pumping pressure.
4. Locating the Pump
Find a location for your pump as close to your water source as possible. Ensure
that this location is on a seperate footing from your home. To do this you can
mount the pump on a concrete tile or concrete base.
5. Power Source
Arrange for an electrician to install an outdoor 10A GPO electrical outlet near
the pump if there is not one there already.

6. Suction
This is the most important part of the installation as errors will cause significant
problems for the system in performance and longevity.
IMPORTANT: A gate valve must be installed at the tank outlets.

To maintain optimum performance from your pump, the suction pipe should be:
- Kept to the shortest distance practical, but not shorter than
the recommended length.
- Re-enforced crush resistant (non-collapsable) hose or pipe.
- All fittings should be air tight.
- Pipes should be equal to or larger than the diameter of the
suction/inlet port.
- Ensure that the suction is completely submerged.
In-line strainers/filters are recommended and regular maintenance is required
to keep them clean and provide maximum pump pressure.
7. Discharge
The length and diameter of the discharge hoses/pipes will affect the pressure
and flow rate at which your pump operates. Pressure ratings of all components
must exceed the maximum pressure of the pump by an appropriate safety factor.
All pipework should be supported independently of the pump.
8. Pump Priming
Ensure that there is at least 200mm of water in your tank, (i.e. that the tank outlet
is covered, and the pump will not draw any air into the system). Open the gate
valve on the tank. Check for any leaks, and repair these if necessary.
If no leaks are present, remove the priming plug (fig.1) to open the priming port
on the top of the pump case.
If the tank is above the level of the pump, water will start to run out of this port.
Replace the priming plug (fig.1) carefully. Your pump is now ready to run.
(Note: If a check valve is installed in the suction line, water may not fill the pump.
If this occurs, follow the instructions below).
If the tank water level is below the level of the pump, you will need to fill the pump
body and suction line. Remove the priming plug (fig.1) and fill the pump body
and suction line using a funnel. It may take several attempts to prime the pump.
Failure to correctly prime the pump may result in damage to the mechanical seal and
cause the pump to leak water. This damage is not covered by warranty so care must
be taken to properly fill the pump with water prior to first operation.

9. Electrical
The pump is supplied with a interconnection appliance coupler and standard
Australian 10 Ampere plug and cord. Connection to the power supply is a matter
of inserting the plug into the suitable socket outlet. Before plugging the power
supply cord into the socket outlet, connect the pump to it using the provided IEC
appliance connectors on the end of the interconnection cords. Ensuring there are
no water traces on the connectors push them firmly into each other to ensure
intended splash (water) proof protection. This connection shall be separated
again only for service purpose and only after the power supply is removed by
unplugging the cord from the socket outlet.
The socket outlet shall be in a dry and flood free location; preferably do not use
extension cords for this very reason and because they can cause voltage drop.
Supply voltage outside limits specified in Model Data
can cause motor to overheat leading to overload
tripping, reduced component life or seriously damage
pump and voids warranty.
We recommend, for additional protection, the pump to
be supplied from socket outlet protected by a residual
current device – RCD (also known as an Earth Leakage
Circuit breaker – ELCB) with a maximum rated residual
current of 30mA.
WARNING
Hazardous voltage.
Can shock, burn, or
cause death.

Operation
1. Start-up / Operation
Ensure you have primed the pump correctly. (Instructions on priming the pump
can be found in the installation section under Point 8. Priming Pump).
The MM Series pump is not self-priming and must be primed prior to use.
The AJ Series pumps are self priming therefore it is possible to start them
without filing the suction pipe with water. However it is still necessary to fill the
pump body. The priming operation requires a few minutes and it may also be
necessary to fill the pump body with water several times (accordingly to length
and diameter of the suction pipe).
Note: If the pump is not used for a long period of time, repeat the priming
procedure before start up.
Start the pump and check rotation of the motor. It rotates in a clockwise direction
when viewing the fan through the cowl behind the motor.
2. Protection switch
The AJ & MM Series of pumps have a built in thermal protection switch. The
pumps stops if an overload condition occurs. The motor restarts atomatically
after it has cooled down (see point 3 on trouble shooting section for information
on causes and corrective actions).
