ATTENTION When cleaning the machine do not use corrosive products, acids, abrasive or steel brushes. Do not directly wash the machine with high-pressure jets of water. 5. 3 REPLACING FILTER CARTRIDGE ITEM TO CHECK The repleace the prefilter follow these steps: Remove the power plug. Remove the filter cartridge, turning it left ¼. Install new cartridge in the machine; take caref about the filter o-rings. Reset the electronic board (if used with time limit funciont) (see § 4. 4. 3). Sterilize the system (see § 5. 8). 5. 4 PRELOAD EXPANSION TANK To check the preload of the pressure tank, follow these steps: Remove the power plug. Empty the expansion tank delivering water to the permeate auxiliary outlet. Remove the side panels and identify the connection of the preload in the tank. With a compressor and a pneumatic gun, bring the preload pressure at 2. 5bar Install the panels and connect the power plug. - 14 - 5. 5 VERIFICATION OF THE SETTING For proper operation of the machine, check periodically the calibrations. All the calibrations must be performed by qualified personnel. 5. 5. 1 Setting pressure switch Install a pressure gauge (0-6 bar or similar) between the permeate outlet and the faucet. Screw two turns the calibration nut of the pressure switch. Open the knob of the tap, after which it slowly close the tap until the pressure gauge reaches about 3. 5 bar. Slowly unscrew the calibration nut of pressure switch until the operation of the machine becomes discontinuous. Apply the glue sealant to calibration nut. v re o ite g lazio e n p s o tato re s s 5. 5. 2 Check operating pressure Install a T fitting and a pressure gauge 0-10 bar (or similar) on the pump outlet line. The operating pressure must be between 6 and 7 bar. 5. 5. 3 Calibrating conductivity probe Open the electronic board box. After 2 minutes, take a sample and measuring the conductivity with a reference instrument properly calibrated. Turn the conductivity calibration potentiometer until the displayed value matches the value measured by the instrument. 5. 6 CLEANING CONDUCTIVITY PROBE CONNECTORS Disconnect the connectors of the conductivity probe. Clean the male and female connectors from possible oxidation. Tighten the connector with pliers and reassembly. - 15 - 5. 7 CLEANING SOLENOID VALVES FILTER Close the inlet water valve.
