7 .0 Electrical circuits Due to the PLC (Programmable Logic Controller), it has been possible to simplify the control circuit within the Duo range, the following diagram have again been subdivided to allow easier understanding of the machine and the working of the circuit. The top control panel has been designed to unplug from the lower loom, these plugs are found at the rear right hand side of the top control panel. The four plugs control the following functions :.

17 .0 Basic Installation. The site : Ensure that there is sufficient space for the installation, servicing and easy access to all mains Isolator switches / valves (i.e. electricity and water). Ensure that the surface the appliance is going to be installed onto is adequately stable and capable of supporting the appliance during normal operation, listed below are the approximate machine weights when fully laden during normal operation. Once installed ensure that the appliance is stable and secure, with its weight being distributed equally and does not tilt more than in any direction. Machine sizes Duo & Duo 00 Duo & Duo 70 Weight 90 Kgs Kgs. Electrical connection : All electrical connections MUST be carried out by an authorised technician and in accordance with local regulations. As a minimum Classic recommends that the following standards are maintained : All appliances are connected via a residual current device (R.C.D.) or earth leakage protection device. EN 00 Supply isolator switch must have all pole separation of more than mm. EN 0 The appliance must be connected to a equipotential conductor, the connection stud is located at the rear of the appliance (a suitable ring terminal shall be required), this is in addition to the earthed electrical supply. Prior to connecting the appliance, ensure that the voltage and the supply fuse complies with the rating plate on the appliance... Electrical rating : Within the Classic range several of the 00mm² basket appliances can be either down rated or up rated electrically, such a procedure MUST be carried out by a Classic approved technician. The down / up rating of the machine is carried out by configuring the terminal block within the appliance to the following Amp Single phase Links removed between L, L and L Ensure link remains between neutrals (N) 0 Amp Single phase Ensure all link remains between lives terminals (L, L and L) Ensure link remains between neutrals (N) Three phase To ensure safety standards are maintained, converting a single phase appliance to three phase requires conversion kit KIT0PH, which must be ordered from Classic and installed as instructed in the above kit. Page

18 . Water connection : The appliance comes with a water supply hose requiring a ¾ BSP male threaded connection at the mains water supply, upon installation and commissioning all water joints must be checked for leaks)... Water supply restrictions : Water supply constraints must be ad herded to : Incoming water temperature c minimum c maximum Supply water dynamic pressure (air break machines, low water pressure not a issue). 0 to bar Rinse booster pump required to bar No modifications required to bar Flow restrictor required bar plus Pressure reducing valve required.. Drainage systems All Duo appliances are pumped drain, upon installation the waste hose and stand pipe must be configured as shown within this manual, also all installations must be with a running / P trap to ensure hygiene : Ø0mm (Ø ½ ) standpipe required Standpipe must be 00 to 0mm ( to ) below the top of the appliance. The end of the waste outlet hose in the standpipe must not be lower than the bottom of the door. The waste outlet hose must be a loose fit within the standpipe. Page

19 .0 Commissioning. Rinse aid & detergent : Ensure chemical tubes are attached correctly to the individual chemical pumps (pumps located behind front lower panel of the appliance). At the bottle end of the chemical tubes, slide the bottle weight onto the tube, now place the tube and bottle weight into the correct chemical bottle. Ensure correct chemical tubes now go to the corresponding chemical bottles. WARNING : Only rinse aids and detergents developed for commercial glass and dishwashers are to be used, rinse aids must be suitable for water temperatures down to 0 c... Rinse aid prime : Switch machine ON and allow to fill Remove the lower front panel (do not to touch any wire connections). Depress and hold button located on the chemical pump bracket. To fully prime, this will take approx ½ minutes. Replace the front lower panel... Detergent / Soap prime : The detergent / soap pump system on these appliances is self priming... Chemical dosage : Chemical doses are preset to the following nominal values, however these values should be calibrated to suit individual sites requirements Preset values (in seconds) Machine sizes Rinse aid Cycle Initial Detergent Cycle Duo 70 0 Duo 0 0 Duo Duo Adjustment of chemical dose is via the timer located under the top panel of the appliance, the timer allows the following values to be calibrated to suit the sites requirements. Demonstration : Classic recommends that prior to leaving the site / installation, the installer demonstrates the following to the end user, as this will ensure the appliance is correctly used What to do in case of an emergency, i.e. how to isolate the mains electricity and water Switching the appliance on. Operating the appliance. Draining down. Switch the appliance off. Clean the appliance, including removal and replacement of all filters. Replenishing and priming of rinse aid and detergent. Page 7
