WASHING
1) Before starting the wash operations remove from the dishes all possible food leftovers
and grease.
2) Pre-soak cutlery and also any dishes before washing, if they have been left for some time
after being used.
3) Place the items to be washed in the baskets.
4) Make sure that the plates are turned towards the exit of the machine.
5) If the operator using the machine does not remove the racks from the exit table, a limit
switch ensures the conveyor and rinse cycle is stopped. Removing the rack from the limit
switch re starts the washing sequence.
INSTRUCTION DURING WASHING
1) Do not put your bare hands in the hot and detergent water in the tanks, as this may cause
burns and skin irritations. Should this happen rinse your hands immediately under fresh
water.
2) When the machine is functioning do not open inspection doors quickly.
3) Use only commercial non-foaming detergents for industrial dishwashers, supplied by
well-known and reputable companies.
4) Isolate the electrical supply to the machine in the case of a breakdown or defective
operation. For all repair work, rely exclusively on a Technical Assistance, approved by
the manufacturer and request that original spare parts be used.
5) At periodic intervals stop the machine, remove tank filters and remove the residues which
have accumulated. Do not remove the pump suction filters when the tank is full. For
machines equipped with the light prewash, remove and clean also the basket filter fit in
the hood.
6) If the rack advancing system has stopped due to the safety device (slip clutch) operating,
stop the machine by pressing the mushroom-shaped emergency push-button "S3" and
remove the obstruction which caused the problem.
7) Ensure the detergent and rinse aid levels, in the respective dispensers are kept topped up.
8) Make sure that water temperatures maintain their regulated values:
wash (probe 3) 50/60°C, rinse (probe 7) 75/85°C.
The non-observance of the above mentioned points may compromise the safety of the
machine and the staff.

1. Press button "S1" and turn switch "Q2" into position "O" to switch off the
machine.
2. Isolate the machine by means of the wall switch and close the water valve and steam
supply (this applies only to steam heating machines).

8. Clean the external surface of the machine with a damp cloth; do not use jets of water, as,
apart from being dangerous, damage to electric components may occur; do not use
abrasive detergents or those containing chlorine.
9. Reassemble all devices into their locations, taking care that:
• the curtains are turned with the short side towards the entry of the items being washed
• the wash nozzles are turned towards the items being washed
10.Keep doors open in order to avoid unpleasant odours, when not in use.
USEFUL ADVICE
Maintenance
IMPORTANT: Before undertaking cleaning and maintenance work, isolate the machine
from the electric supply by switching off the wall switch.
Regular check and cleaning of the nozzles is advisable. The frequency of cleaning depends
on the quantity of leftovers and foodsoiling left on the crockery, insufficient cleaning of
nozzles will give poor wash results. Do not use corrosive products such as hypochloride
sodium (bleaching products), acids in general, steel wool and steel brushes for cleaning the
machine inside and outside.
To ensure the machine is kept in a perfect hygienic condition, it is advisable to carry out the
following periodic operations.
