7. SECURITY TIPS
l
Obey absolutely valid regulations on the electrical security
l
Never run pump dry
l
Pumping inflammable, as well as all other aggressive liquids is prohibited
l
Pay attention to the medium temperature max. 35°C
l
Never pull the pump on the electrical cable or pressure hose
l
Avoid cross section narrowing
l
Pay attention to the given particle size
l
During longer unused times, clean the pump, wash it out with clear water, dry and store it
at room temperature
l
Test wells for enough flowing water (dry run danger)
l
The pump is to be secured through a RCD circuit breaker with a release current of 30 mA.
l
The electrical connections are always to be carried out by an authorised professional
l
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 adhe-
ring to safe instructions and resulting dangers.
l
Cleaning and maintenance must not be carried out by children without supervision.
l
Under certain cirumstances, it is possible that that contamination of water is caused by leakage.
THE MANUFACTURER EXPLAINS:
l
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.
l
To reject every responsibility for the damages which originate from the improper use of the pump.
8. SERVICING
It must be regularly checked the pump filter and clean if necessary. The service inter-
vals are based on the respective usage. We recommend a weekly control in much dirt
accumulation, if necessary daily inspection. 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:
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.

Protection
EAA
This code appears when the communication failure occurred between drive board
and control board and it should be troubleshooting manually.
9 Locked-rotor Protection EH This code appears when the rotor is locked and it should be troubleshooting manually.
10 Lost Phase Protection EP This code appears when phase is lost and it should be troubleshooting manually.
11 Leakage Protection LL
When the pump runs continuously for 4 hours, it automatically enters the protection
program. After eliminating leakage or confirming that it works properly, it can be
restarted by changing parameters or power off.
