ICE TECH SS / SP Technical ServiceManual18c) CHLORINATED WATER: Chlorine taste can be avoided by installing a carbon filter(NOTE: You may encounter water with all aforementioned properties.)d) PURIFIED WATER: A 10% reduction in overall production may occur.4.3. Connecting unit to water source (water-cooler units)• Use 1.3 m. flexible tube (with the two filters attached) provided. NOTE: We advise using asingle faucet fixture.• Water pressure should be between 0.7 and 6 Kgs/cm2. (10/85 Psi.)• If water pressure exceeds these values, installation of appropriate corrective units will benecessary.• It is important that water tubing does not come close to or in contact with any heat sourcesor heat generated by unit as this could decrease production.4.4. Connecting unit to drain (water-cooled models)• Drain must be located at least 150mm below machine level. Drain tube must have an innerdiameter of 30mm and a minimum gradient of 3 cm per metre.4.5. Electrical connection• Unit is provided with a 1.5 m cord and Schucko socket.•It is recommended to install a switch and adequate fuses. Nominal voltage and intensity areindicated on rating plate as well as on this manual's technical pages. Voltage fluctuations greaterthan 10% can cause problems or prevent machine from starting.•Line to base of plug must have a minimum section=2.5 mm2.•Be sure voltage indicated on rating plate corresponds to that of mains supply.IMPORTANT!Supply socket must be properly earthed. Be sure to check standard for country where applianceis going to be installed.
