It is essential that the operating instructions are read before the unit is used for the first time. Ensure that the operating instructions are with the unit when it is given to other persons. General information
In these operating instructions, this symbol indicates points of particular importance to safety. The instructions at these points must always be observed in order to avoid a risk of serious injury. [. . . ] Subsequently, the green ON indicator lights to show that the unit is ready for use. Start the water supply system by operating the switch on the DD EC-1 diamond core drilling machine. Adjust the water volume as desired by turning the regulator
Rinse out the remaining slurry and, if necessary, remove dried-on remains. Fill the container as described above, close it and then insert it in the housing. Regenerating the main filter Regeneration of the main filter is recommended in the following situations: When malfunctions caused by blockage of the main filter are experienced Each time the container is refilled Remove the container from the housing as described above and open it. Instead, grip it only by the black grip section on the underside of the main filter (reduces risk of breakage) . Clean the main filter under running water, using the cleaning pad supplied, by rubbing it in a longitudinal direction on all sides until the light colour of the ceramic body reappears . During this process, the outermost surface of the ceramic body is rubbed off. This regeneration procedure can be repeated up to about 20 times until the minimum wall thickness of the ceramic body is reached. The main filter must be replaced as soon as the black plastic ring inset in the middle of the ceramic body is flush with the surface of the filter. Failure to observe this point could result in cracking or breakage of the ceramic body . A defective main filter may cause damage to the recycling unit and to the diamond core drilling machine. Screw the main filter into the cover until resistance is clearly felt. Screwing the filter in beyond this point does not improve the efficiency of the filter seal and may result in permanent damage to the filter or cover parts. Fill the container as described above, close it and then insert it in the housing. Drying the main filter In rare cases, regeneration of the main filter may not be sufficient to clear a blockage. Should this be experienced, allow the main filter to dry for at least 24 hours, standing upright with the thread at the top, in a warm, dry place before it is reused. Replacement main filter The main filter is a wearing part with a limited life expectancy. The housing has provision for storing a spare main filter (not supplied). The container must be removed on order to access the storage location and insert a spare filter. Insert the grip section of the spare main filter in the holder in the base of the housing at an angle and then bring the filter into a vertical position until it engages with the plastic tab. To remove the spare main filter, lift the plastic tab slightly and pull the filter out of the holder to the side.
