15. Maintenance
Your system requires regular, proper and professional maintenance.
We recommend that you secure a service contract to ensure that the necessary maintenance
work is carried out.
You then have the certainty of a high operational safety and reliability.
The service protocol appended to the service contract serves for certification that maintenance
work specified in the contract has been carried out by authorized service company.
To ensure your system will work reliably for a long time, it must be checked, serviced and cared
for at regular time intervals in accordance with these Operating Instructions!
For this reason, the operating instructions must be readily available to operating and mainte-
nance staff at all times, and be carefully followed!
Any maintenance work which should become necessary during the validity of the guarantee is
only to be carried out by a service professional which is expressly authorized to do such work.
The operating-staff assigned is committed to carry out daily/weekly checks.
During the agreed term of validity of the guarantee, maintenance is to be carried out weekly
according to the maintenance record sheet supplied with the Operating Instructions.
The calibration of the conductivity display is only to be carried out and recorded by customer
service.
Cleaning and disinfection of supply tanks, piping, filter housings etc. Is performed for reasons of
hygiene and has no effect on the technical condition of the system. These components must be
cleaned and disinfected whenever algae or slime are detected inside them or at least once
yearly.
Checks or maintenance work on electrical equipment are only to be carried out
after the system has been completely separated from the electrical supply by
unplugging the mains plug and ensuring that it will not be inadvertently plugged
back in. Such work is only to be carried out by qualified electricians.
