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 points B on installation diagram – run waste directly behind the machine or through open base.

Power

Machine requires 3 Phase, Neutral and Earth, 400/415V, 25A/ph, 50Hz, permanent wiring via wall switch to point C on installation diagram. Wash pump rotation must be checked after installation to ensure correct direction (causes excessive noise and damage).

Ventilation

10 m³/min = 170 l/sec – refer points F on installation diagram – extraction via connected ducts or overhead canopy.

Commissioning Procedure

Connect all services as above. Turn on water and switch on power. Close machine door and switch machine on, machine will fill. When water sprays from rinse arms inside machine, switch machine off at wall. Remove lower front panel and switch commissioning switch by breaking label over same.

Installation Checklist

Complete attached Installation Checklist to ensure machine is installed and running correctly, and operator is familiar with operating procedures.

Troubleshooting

If machine doesn’t fill after switching on power, check and ensure that hot water supply tap is open, water supply pressure is not below specification and Dual

Check Valve is correctly installed (arrows on the dual check valve’s body specify water flow direction).

Performance

Hot Water Supply

An adequate supply of water at the correct temperature and pressure is essential for effective operation of your machine. Refer Installation information for detail.

Water softening is recommended in hard water areas - especially for glasswashing.

Pre-rinsing

Pre-scraping of dishes is required by Food Hygiene Regulations. The best method is to pre-rinse with warm water with a Fisher Pre-rinse Unit - or alternatively by scraping or dunking in water. Cutlery should be pre-soaked in warm water, preferably containing cutlery pre-soak compound - refer your chemical supplier.

Racking Procedures

Do not overload racks or cutlery containers, minimise 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 switch to faster cycles when it is necessary.

Detergent

Use of correct type and quantity of detergent is essential to the performance of the machine. Low foam specialty products are recommended. We strongly recommend that you use a professional dishmachine chemical supplier - and will be pleased to recommend a supplier in your region. Discuss with them the use of cutlery pre soak solution, detergent and drying agent.

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 wash ware.

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 – refer Maintenance section.

Maintenance

Regular Cleaning

1. Remove upstand 1 to drain wash tank. Remove scrap trays 2 and wash pump inlet filter 3. Clean them with water and a brush to clear grids.

2. Remove lower wash arms 4 – lift to unhook and then withdraw. Remove upper wash arms 5 – push the catch 6 up and then withdraw. Remove rinse arms 7 and 8

– push the catch 9 up and withdraw. If necessary, remove the end cap screws 10 from the wash and rinse arms. Flush arms with water using a toothpick or paperclip, if necessary, to clear jets.

Regular Servicing

Regular servicing of the dishwasher is essential to keep the machine in top working condition and get the best performance results.

Please contact your Service Provider to organize regular servicing of the dishwasher.
