4.2
Using the machine
DIN 10510 is a German standard which describes how the washing process must
work in rack conveyor or flight type machines in order to ensure good washing results. Amongst other things, it recommends that the contact time should be
around 120 seconds for normally soiled loads. The contact time is the time which
the load spends in a wash or rinse zone with washing water containing detergent.
In principle this means the period from when the load enters the pre-wash zone
to when it is rinsed with clean water in the final rinse zone. The standard is a useful means of comparing the capacity and consumption of different dishwashers.
4.2.1 Washing
Numbers in brackets refer to the pictures in the chapter entitled "The machine’s
design".
•
•
•
Before trays are fed into the machine, they must be soaked to remove
dried-on pieces of food.
Push in the trays on the long side first through the feed opening. The belt
and the washing process will start.
For the movement of trays through the machine to continue, new trays
must be fed in all the time. For each tray that is fed in, the belt moves just
one short step and then stops. The next tray that is fed in will start the belt
again. When no more trays are fed into the machine, it will stop.
4.2.2 Storage in the tray dispenser
If washed trays are stored in the tray dispenser connected to the machine's outfeed end, a message will appear on the display when the dispenser is full of trays.
Change the dispenser. When an empty dispenser is put in place, the machine is
ready to wash again.
The machine can also be connected to a tray exchanger for two dispensers.
When one dispenser is full, the trays are automatically switched to the other and
the machine does not stop until both dispensers are full.
4.2.3 Changing the water
Numbers in brackets refer to the pictures in the chapter entitled "The machine’s
design".
For best wash results, it is important that the water in the tanks is changed if it
becomes too dirty. The water should always be changed if foam begins to form in
the chemical wash tank.
•
•
•
•
Switch the machine off by pressing button (10).
Remove the filters (19) and empty the machine by turning the level pipe
(22) a quarter of a turn.
When the tank is empty, close the level pipe and refit the filters.
Refill the machine with water.

After use
Ensure that the power supply to the machine and any dishwashing equipment
powered by the machine is switched off during manual cleaning.
HACCP is a preventive inspection system to ensure hygiene requirements are
met during the washing process and cleaning of the machine. As a result of its
design, the machine meets strict hygiene requirements. Regular, thorough cleaning is also important from a hygiene perspective. A machine that is properly
cleaned helps produce a good wash result, reduces the risk of dirt accumulating,
increases the service life of the machine and reduces the risk of emergency shutdown.
See the WEB Tool manual for the HACCP alarm options.
