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.
Water Supply
Hot water temperature 65°C ± 5°C
Connection 20 mm (3/4” BSP) male
Hot water consumption 350 litres per hour approximately
Pressure 200-400 KPa = 30-60 Psi
Backflow prevention Dual Check Valve fitted on Washtech models
Cold Water Supply the same pressure and connection as above
Above 400KPa 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 to points B on the installation diagram – run waste
directly behind the machine or through open base.
Power
Machine requires 3 Phase, Neutral and Earth, 400/415V, 40A/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 (excessive
noise and damage with incorrect direction).
Ventilation
15 m³/min = 250 l/sec – refer points F on installation diagram – extraction via
connected ducts or overhead canopy.
Detergent
Refer your professional chemical supplier for advice on wash and rinse chemicals
and dispensers.
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.
