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
\RXUKDQGVRU¿QJHUVZKHQWKHSXPSLVFRQQHFWHGWR
the power supply.
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
WKLVFDVHWKHLQOHWSLSLQJRIWKHSXPSPXVWEH¿OOHG
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
can be mounted outside unprotected from rain.
7KH,3LVDVSHFL¿FWHVWLQYROYLQJVSHFL¿F
VSUD\LQJRIWKHSXPSIRUDVSHFL¿FWLPH
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-
ned' if a connection becomes loose and water spills on

7.2 Inlet pipe (intake side)
,IDVXI¿FLHQWDPRXQWRIZDWHUGRHVQRWUHDFKWKHSXPS
because the drag of the inlet pipe is too strong, the
pump will use a lot of power and the electronics might
become overheated in the long run.
Any coupling must be 100% air-proof. If a tube is used

pipe.
It is very important that the initial inlet at the pump
is straight. (Minimum distance of 3-5x the diameter
RIWKHLQOHWSLSHIURPWKHKRXVLQJWRWKH¿UVWERZ
7KLVPD[LPLVHVWKHHI¿FLHQF\IDFWRUEHFDXVHWKHZDWHU
enters more laminary at the impeller.
If the inlet piping is longer than max. Ø x 10, the inlet
piping must be 1 size larger than the intake of the
pump.
7.3 Pressure pipe (Pump outlet/pressure side)
The pressure pipe must have the same diameter (3"/90
mm) as the intake of the pump in order to minimize
SUHVVXUHORVVKLJKÀRZVSHHGVDQGQRLVH
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).
