INTRODUCTION

We would like to congratulate you on the purchase of our pump. We appreciate your trust. That‘s why funtional security and operational safety stands by us on first place.

To prevent damage to persons or property, you should read this user manual carefully. Please observe all safety precautions and instructions for proper use of the pump. Failure to follow the instructions and safety precautions can result in injury or property damage.
Please keep this manual with the instructions and safety instructions carefully in order to at any time you can restore them. Please always download the latest version of the user manual of www.profi-pumpe.de under „downloads“. This shall always prevail.

IN GENERAL

The pumps are developed according to the newest stand of technology, manufactured with much care and go under strict intensive controls. These pumps were optimised by us in particu-lar for the special demands in dirty water 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 writ-ten form.

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-filtered to 0.2 mm particle size
The pumps are made for the following ranges of application:

domestic water use from wells with diameter from 3-inch diameter
circulation of large accumulations of water from containers
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 flammable 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.

OPERATION

The installation must be performed by a qualified 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 modification is technically correct, so this warranty is void. It must be en-sured that the pump is sufficiently cooled during prolonged operation.

ASSEMBLING

Due to their size, pump and motor modules are delivered partly separately. The assembly is carried out as shown in Figure 1.
Slide the motor shaft into the housing of the pump shaft. Screw the two modules together.
Please make sure that the screws are tighten-ed crosswise and evenly.
Then mount the filter strainer as shown.

INSTALLATION SCHEME

The installation must be carried out as shown in Fig. 2a. We recommend the installation of a pressure switch (Fig. 2b), which monitors the function of the pump and protects it from damage.

SECURITY TIPS

Obey absolutely valid regulations on the electrical security
Never run pump dry
Pumping inflammable, as well as all other aggressive liquids is prohibited
Pay attention to the medium temperature max. 35°C
Never pull the pump on the electrical cable or pressure hose
Avoid cross section narrowing
Pay attention to the given particle size
During longer unused times, clean the pump, wash it out with clear water, dry and store it at room temperature
Test wells for enough flowing water (dry run danger)
The pump is to be secured through a RCD circuit breaker with a release current
of 30 mA.
The electrical connections are always to be carried out by an authorised professional.
The pump may be used by children aged 8 years and above as well as persons with reduced physical, sensory or mental abilities or those who lack skills, experience and knowledge only if they are supervised. These aforementioned persons should only use the appliance while adhering to safe instructions and resulting dangers.
Cleaning and maintenance must not be carried out by children without supervision.
The pump must not be used or operated under any circumstances when there are people in the same water.
Under certain cirumstances, it is possible that contamination of water is caused by leakage.

THE MANUFACTURER EXPLAINS:

To take over no responsibility in the case of accidents or damages on the basis of careless-ness or disregard to the instructions in this book.
To reject every responsibility for the damages which originate from the improper use of the pump.

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 fill 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:

Intactness of the electric cable
That the connection hoses are not bent or broken
Cleanness of the pump medium

Moreover, the pump should be emptied with risk of frost, be washed out with clear water and stored dry.
