2.2
Our warranty for defects is strictly limited to
supplementary performance. We will eliminate any
defects or deliver substitute goods at our discretion.
Where supplementary performance fails or is disputed
or impossible, the customer has the right to withdraw
from the contract. Air-Aqua and the manufacturer
explicitly limit the warranty to the pump itself. We are
not liable for any consequential damage or damage
caused by a malfunction or failure of the pump, such as
loss of animals.
The customer is responsible for providing back-up
devices in the case of a potential malfunction or failure
of the pump.
2.3
The customer is required to conduct a detailed
inspection of the goods immediately after delivery.
Any defects should be reported immediately in writing.
Hidden defects should be reported immediately after
their discovery. The customer should report any

In general, when put out of service, the pump must
be cleaned extremely thoroughly. The pump must be
stored in a dry, warm place to prevent condensation/
moisture getting into the electronics which could cause
damage when used again.
Before it is put into operation, the ease-of-movement of
the impeller must be manually checked. If the impeller
cannot be moved round by hand, the pump must be
disassembled and cleaned completely. The plug may
not be disconnected from the pump whilst the device
is in use. This can result in serious damage to the
electronic components and cause dangerous situations
due to grounding problems.

electrician, your dealer or Air-Aqua BV.
5. Fields of application
The FlowFriend pump is suitable for freshwater,
brackish water and for pumping other non-aggressive,
non-explosive liquids that do not contain oil. It can
pump clean as well as – to a certain extent – polluted
water. The pump is not suitable for water with larger
particles. The pollutants may not exceed 10 mm in size.
In general the pump should be used for applications

as water not containing solid particles, which could
damage the impellor/bearings and/carbon ring/pump
housing. Examples of particles or pollutants which are
not suitable are sand, lime precipitation or pyrolusite
after a manganese peroxide treatment in a pond.
Damage caused by such pollutants in the water does
not fall under warranty or service.

Damage caused because the manual was not read
thoroughly does not fall under warranty.
When unpacking the pump, check whether all parts
have been delivered completely and undamaged. Any
damage detected must be reported to your retailer
within 24 hours of purchasing the pump. When
unpacking the pump, the inside of the pump may be
wet. The pump is tested before it leaves the factory.
The pump has to be purged with water thoroughly
before usage.
Please check the pump for damage before you operate
it. Do not use the pump if it is damaged. Please inform
your retailer immediately if the pump is used despite
being damaged. Any warranty and liability will then be
invalid.
Remove the plug from the electric socket and make
sure that the pump cannot be switched on. During
the course of the installation, the pump may not be
connected to the power supply. To avoid injury, take
care not to reach into the opening of the pump with

7. Operating the pump
NEVER USE THE DEVICE WITHOUT WATER
THROUGHPUT.
THE PUMP CAN AUTOMATICALLY START WHEN
THE POWER CONNECTION IS ESTABLISHED.
The pump may only be used in a horizontal position.
It must stand on a stable, solid base. The inlet pipe is
connected to the suction side of the pump.
It must be assured that the pump can be de-aerated
through the outlet. The pump should ideally be placed
below water level.
The pump can be only placed out of the water (dry).
Adequate air ventilation must be assured. Furthermore
the pump may not be exposed to direct sunlight. Place
the pump as close as possible to the actual water
connection. The inlet piping must therefore be as short
as possible.
We strongly recommend placing the pump below water
level. If the pump is placed above water level, the
installation of a back pressure valve is mandatory. In

with water before the pump is operated. In such a
setup, the risk of the pump running dry is very high,
if the back pressure valve does not work properly.

Damage caused by the pump running dry is excluded
from warranty.
7.1 Siting the pump
The FlowFriend has a protection class IP55. IP55
water protection does not mean that the pump

Remember that electronics and water are enemies.
Provide good protection from rain if mounted outside.
Damage caused by water is not covered by warranty.
Siting is preferably at a minimum of 10 cm above
ground level. This will prevent the pump being 'drow-

If the inlet piping is longer than max. Ø x 10, the inlet
piping must be 1 size larger than the intake of the

The best thing is if you enlarge the pressure pipe
directly after the pump outlet (4"/110 mm) if the outlet
piping exceeds 10 meter, in order to maximize the
pump capacity and to safe energy.
Reducing of the diameter of the pump outlet is at the
FlowFriend pump to avoid.
7.4 Electrical connection – setting-up operation
Check whether voltage and frequency on the type label
of the pump match the supply voltage. The person
responsible for the installation must check whether
standard grounding is available.
It must be checked whether the electrical installation
has a highly sensitive earth leakage circuit breaker
(ELCB/GFCI) (30mA – DIN VDE 0100T739).

low maintenance. The necessary maintenance work is
usually limited to checking the impeller for obstruction.
Remove obstacles from the impeller with a slender,
pointed tool. A decreasing supply rate is often the result
of dirt. Possible calcinations must be removed with a
very soft acid like vinegar. Avoid applying pressure to
the sides of the impeller or the rotor. The pump head
can be disassembled completely for cleaning.

within 2-3 days.
8.1 Disassembling/changing the pump housing
By plugging/unplugging the power plug, the pump
can be made ready for operation again. Do not
circumvent the electronics to make the pump run
again by constantly plugging/unplugging the power.
If the FlowFriend pump switches off, there is always
a problem which must be remedied. This is usually a
cleaning interval that is to be implemented. Continuous
circumventing of the pump electronics may cause motor
damage which is not covered by guarantee or goodwill.
Furthermore, major impurities may generate vibrations.
We recommend checking the FlowFriend pump after
three months to determine the possible maintenance
intervals. Depending on precipitation, this may be
between 2 and 24 months.
Unplug or disconnect the power plug and gently remove
the pump from the system. Remove the 8 bolts on the
back of the pump housing. Then gently remove the
pump housing itself. Check the impeller for snail shells,
