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.
