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. Wash cutlery unsorted, handles down.

Cycle times are short and water consumption per cycle low – so
there is no advantage in overloading racks.

CYCLE TIMES

The XU has a 2 minute cycle.

CHEMICAL

Correct type and quantity of detergent is essential for good results.
Use good quality chemicals and regularly check containers. Discuss
the use of drying agent and cutlery pre soak solution with your
chemical supplier. Detergent concentration can be changed by
adjusting the timer (refer service manual). Rinse Fluid is factory
set to a low injection rate, and will take many cycles to prime. The
operator can adjust this via the adjusting screw on the front cover
(refer service manual).

DRYING

Single tank commercial dishwashers do not have a drying cycle.
However, the machines do rinse at high temperatures which
promotes fast drying particularly when drying agents are used.

At the end of the cycle promptly remove 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.
