Failure to comply even partially with installation instructions may void the warranty. Positioning Unpack machine, check for damage and complete delivery. Install machine on sound waterproof self-draining floor and use adjustable feet to level machine. Allow room for detergent to one side of machine or in adjacent cupboard. 20litre container requires about 450H x 250W x 350D, but smaller containers are available from many suppliers. Benchwork Refer Bench Details diagram. Corner installation is not recommended for this model. We recommend sink smaller than rack with guide to prevent rack falling into sink. Align sink with dishrack path as shown. Water Supply Hot water temperature Connection Flow rate minimum Consumption per cycle Backflow prevention Pressure 65°C ± 5°C 20 mm (3/4" BSP Male) 20 litres per minute 3.5 litres approximately DCV = Dual Check Valve fitted standard 200-400 KPa = 30-60 Psi. Above this range fit pressure limiter. Don’t use small diameter plastic supply lines especially below this range when optional rinse booster pump may be required. FLUSH supply line before connection. Poor quality supply or excessive water hardness may affect performance or damage machine – filtration and/or softening is recommended. Waste 40 mm gravity drain – refer point B on installation diagram – run waste directly behind the machine or through open side panels or base. Power Machine requires 3 Phase, Neutral and Earth, 400/415V, 25A/ph, 50Hz, permanently wired via wall switch mounted adjacent to machine. Wash pump rotation must be checked after installation to ensure correct direction (causes excessive noise and damage). Installation Checklist Complete attached Installation Checklist to ensure machine is installed and running correctly, and operator is familiar with operating procedures. Troubleshooting If the machine doesn’t fill after switching on the power, check and ensure that the hot water supply tap is open, water supply pressure is not below specification and Dual Check Valve is not faulty and correctly installed (arrows on the dual check valve’s body specify water flow direction).

Installation Read the Operator Manual. Correct installation, including an adequate supply of water at the correct temperature and pressure is essential for effective operation of your machine. Refer installation instructions for details. Drain hose outlet height is important on some models. Always install on a sound self-draining floor. Water softening is recommended in hard water areas - especially for glasswashing Pre-rinsing Pre-scraping of dishes is required by hygiene regulations. The best method is to pre-rinse with a pre-rinse spray unit or alternatively by scraping or dunking in water. Cutlery Procedures Pre-soak cutlery in warm water, preferably containing cutlery pre-soak compound - refer your chemical supplier. Do not overfill cutlery containers. Cutlery should be loose with handles down. Sort after washing rather than before. Cutlery of only one type nests together and obscures wash water. Racking Procedures Do not overload racks, minimize the overlap of crockery. Cycle times are short and water consumption per cycle low - so there is no advantage in overloading racks. Cycle Times For multi-cycle machine use the longest cycle whenever possible. Note that water consumption does not increase with longer cycles. Only choose shorter, faster cycles when necessary. Detergent Use of correct type and quantity of low foaming detergent is essential to machine performance. Ask a professional chemical supplier to recommend the best types and concentrations of detergent, rinse fluid and cutlery soak for your situation. Note that detergents are hazardous. Poorly formulated detergents, particularly those containing chlorine, can shorten the life of dispensing systems and the machine itself. Dishwashing Procedures for best results Drying Single tank commercial dishwashers do not have a drying cycle. However, the machines do rinse at high temperatures which promote fast drying particularly when drying agents are used. We recommend prompt removal of the rack from the machine - leave the rack on the bench for 2 to 3 minutes before emptying. This time will be reduced with correct use of drying agent (rinse fluid) which reduces water surface tension and allows water to drain quickly from washware. For advice on drying agents and injectors refer to your chemical supplier. Daily Cleaning It is essential that the machine is drained and cleaned at the end of each day. Drain the machine then remove, clean and replace filters as per the operating instructions. Regularly check the wash and rinse jets and clean them if necessary – see below. Regular Cleaning Remove scrap trays1 and wash pump inlet filter2, where fitted, and rinse or brush clean. Remove wash and rinse arms by undoing the central thumbscrews3. If necessary, remove the end cap screws4 from the wash arms and the end screws5 from the rinse arms and flush the arms with water and/or use a toothpick or paperclip to clear jets. Note: arms and filters vary with model and may appear different from this illustration e.g. those models with plastic wash arms have removable jets for ease of cleaning Regular Servicing Regular servicing of the dishwasher is absolutely essential to keep the machine in top working condition and obtain the best performance. Please contact Moffat or your Authorised Service Provider to organize regular servicing of the dishwasher - discuss a Preventative Maintenance Agreement for optimum performance and long machine life. Note : these are general instructions to assist in getting the best performance from Washtech dishwashers – some comments and / or illustrations may not apply to every unit. Operating Instructions Start up Fit drain upstand, wash pump filter, scrap trays and shut door. Turn wall power switch on and select any cycle (1, 2 or 3). Power light glows red and machine fills automatically. Wash Ready light (water symbol) glows amber when wash tank is ready. Rinse Ready light (tick symbol) glows amber when the machine is up to required temperature and ready to run. Operation Select required cycle (1, 2 or 3 for 2, 4 or 6 minutes cycle accordingly). Try cycle 3 initially and switch to faster cycles only if necessary. Load rack into machine and close door to start the machine. Cycle light glows green while machine operates. When Cycle light goes out, cycle is complete. Open door and remove rack. After removing rack from maching, DO NOT shut door as machine will start again. NOTE: Machine will not operate unless Ready lights are on. Shut down every night Turn machine and wall power switches off. Remove drain upstand to drain wash tank. Remove scrap trays and wash pump filter and rinse clean. Replace drain upstand, filter and scrap trays.
