areras. Make sure after unpacking the pump that the data given on the type label match with the included operating
instructions. In case of doubt the pump is not to be used.
Transport damages are immediately to be reported to the package distributor and to us in written form.
3. rangeS of application
These pumps are made for pumping clear water (free of mud and sand and aggressive chemical substances (see
technical data). The water may have to be pre-fi ltered to 0.2 mm particle size
The pumps are made for the following ranges of application:
l
domestic water use from wells with diameter from 3-inch diameter
l
circulation of large accumulations of water from containers
l
Other plain water pumping
important!
The pumps are designed for pumping clean water and chemically non-aggressive liquids. Any guarantee is void in
case of improper use. They are not suitable for pumping fl ammable liquids or for use in places where there is a risk
of explosion. The pumps are designed for home use in the house and garden.
These pumps are designed for continuous use provided (max. 20 interruptions per hour). Never run more than
2-3 minutes against a closed valve pump. (Install dry running protection) pump adequately secured against dry running.
The pump must not be used in swimming pools.
Not suitable for use with solar photovoltaic panels.
Please read the user manual before using

Safety inStruction and WarningS
Mount the THERMAL PROTECTOR SWITCH BOX
(only included With the brunnen-Star 750-4)
at a place
suitable according to the protective class. Assure that a 30mA RCD circuit breaker secured outlet is installated. Then install the
pump cable in the thermal protective switch box. Lead the cable through the screw connection opening from the outside into the
box. The wires are marked with numbers.
Secure the cables in the electrical clamp strip according to the numberings (See fi g. right). Tighten the screw connection of the
cable realisation and screw the lid together. Pay attention that the rubber sealing ring sits tight.

6. guarantee regulationS
For all manufacturing and material defects, the statutory warranty applies. In these cases we take the replacement
or repair of the pump. Shipping costs shall be borne by our company, except as required by law. Please report the
warranty on our service platform http://www.profi -pumpe.de/service.php. We will inform you how to proceed with
case-related. Returns please suffi cient postage. Unfortunately not prepaid returns can not be accepted because they
are fi ltered out before delivery. Our service we provide in Germany.
The warranty does not cover:
l
Improper installation (self-installation, unauthorized persons)
l
Material wear (sealing rings, impeller wheels, impeller chambers)
l
Unjustifi ed interventions or changes in the pump
l
Damages by selffault
l
Improper servicing and improper use
l
DRY RUNNIG (Also partially!) of the pump
moreover, we give no damage compensation for secondary damages!
4. operation
The installation must be performed by a qualifi ed professional.
Please, check each time before using, the electrical connections and the cables are not damaged. Check
before the installation whether the electrical connections are earthed according to the statutory regulations
and are installed. The pump is to be secured through a RCD circuit breaker with release current of 30 mA.
Also, it is NOT recommended to perform, for example, a cable extension. It is not certain whether this modi-
fi cation is technically correct, so this warranty is void. It must be ensured that the pump is suffi ciently cooled
during prolonged operation.
5. SerVicing
Under normal pumping conditions the pump requires no servicing. From an operating period (with clear
water) of approx. 2000 hours the mechanical components should be checked: impeller wheels, chambers,
sealing rings etc. on wear and if necessary be changed. After 3000 pumping hours the oil in the chamber
should also be changed, if necessary (only with oil-dipped engine types!). Please, only fi ll it up to 80% and
check the sealing rings always for density.
With abrasive materials like sand the servicing duration can become shorter.
The following controls should be carried out regularly:
l
Intactness of the electric cable
l
That the connection hoses are not bent or broken
l
Cleanness of the pump medium
Moreover, the pump should be emptied with risk of frost, be washed out with clear water and stored dry.
