[. . . ] In water cooled models, condenser obstruction is likely. Installation of a high quality water softener is recommended. c) CHLORINATED WATER: Chlorine taste can be avoided by installing a carbon filter (Part # 207509). (NOTE: You may encounter water with all aforementioned properties. ) d) PURIFIED WATER: A 10% reduction in overall production may occur. Connecting Unit To Water Source •Use 1. 3 m. flexible tube (with two filters attached) provided. NOTE: We advise using a single 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 be necessary. •It is important that water tubing does not come close to or in contact with any heat sources or heat generated by unit as this could decrease production. Connecting Unit To Drain (Water Cooled Models) •Drain must be located at least 150mm. Drain tube must have an inner diameter of 30mm. with a minimum gradient of 3 cm per metre. Electrical connection • Unit is provided with a 1. 5 m cord and Schucko socket. 14 • It is recommended to install a switch and adequate fuses. Nominal voltage and intensity are indicated on rating plate as well as on this manual's technical pages. Voltage fluctuations greater than 10% can cause problems or prevent machine from starting. • Line to base of plug must have a minimum section=2. 5 mm2. • Ensure voltage indicated on rating plate corresponds to that of mains supply. Machine levelling Place machine where it is required, and level the machine ONCE all four legs have been screwed on Space requirements There should be a 150 mm gap on sides and top of the machine so as to allow air to circulate and prevent heat build-up. Float (buoy) valve level This valve is factory set, but may need to be adjusted if mains water pressure is very high or very low. To do so, loosen the two small screws which connect the micro-switch to the steel support. Move micro-switch as required and tighten screws. Water level must be about 5mm below the evaporator coil to, otherwise there may be difficulty in releasing cubes in winter. Note that if mains pressure is subject to large fluctuations, it will be difficult to maintain a constant water level, in this case it may be advisable to install a pressure regulator on the water mains line. IMPORTANT!Be sure to check standard for country where appliance is going to be installed. 15 OPERATION Preliminary Check a) Is machine levelled?b) Are voltage and frequency of main supply the same as indicated on rating plate?d) Is air circulation and room temperature adequate?(Air-cooled models) ROOM TEMPERATURE WATER TEMPERATURE MAXIMUM MINIMUM 43° C 5° C 35° C 5° C e) Is water pressure adequate? MAXIMUM MINIMUM 0. 7 Kg/cm2 6 Kg/cm2 ATTENTION: Check that voltage and mains frequency are the same as in the rating plate. Starting up Once preliminary check has been completed (ventilation, connections, temperature, etc. ), proceed as follows: 1) Open water faucet. [. . . ] B) The lower cam micro-switch is faulty or B) Replace micro-switch or connect wrongly connected. (Only on water condensed machines) C) Regulate water presostat to 40ºCPresostat faulty or opens too much 43ºC. A) Water level in pan too low or too high. C) fan pressostat or cooling water inlet valve out of order or wrongly adjusted. [. . . ]
