GenPure Thermo Scientific
Regular servicing of your system ensures that the quality of water is maintained. We recommend a
service contract with a factory authorized service company to ensure that the system is properly
maintained. You then have the certainty of a high operational, safe, and reliable water purification
system.
To ensure error-free operation, your system 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 maintenance staff at all times, and be carefully followed.
Calibration of the conductivity is only to be carried out and recorded by a factory-authorized service
technician.
Cleaning and disinfection should be performed at least once yearly, or when the ultrapure cartridge is
replaced, or when bacteria is present in the product water.
Maintenance intervals
Consumable materials are to be replaced according to the directions below. The intervals were
determined for the average user and are completely dependent on the actual feed water quality and
volume of water used daily.
*Please keep in mind that the life of your consumable is directly dependent on the quality of the feed
water and the amount of water used daily.
Control and maintenance work on electrical systems are only to be carried out by an
appropriately trained, skilled electrician.
