Preparation for washing and rinsing

The following preparatory work must be carried out at every startup

Open the door.

Place the screen and stand pipe in position.

Close the door.
Danger of crushing.
Close the door with both hands.

Press the on/off button to switch on the machine.
During the filling and heating phase, the light above the preselection key will flash.
When the light remains constantly lit, the machine is ready for operation.
The time required to reach operation readiness depends on supply water temperature
and the installed boiler or tank heating capacity.
If using a cold water connection, this
process takes approx.:

Manual dosing of detergent

If there is no detergent dosing pump, the detergent must be added manually to the wash-
ing water. To obtain a concentration of 2 g/l, an initial amount of 40 g and a later addition
of 30 g after each of 5 cycles should be added.
If the detergent is in powder form, the powder should be scattered evenly on the water in
the tank and dissolved after the tank has been filled. This will prevent discolouration of
stainless steel parts.
8.4

Automatic dosing

The required detergent (detergent dosing pump: option) and rinse aid is transported out
of the containers into the tank, resp. boiler, via electronically controlled dosing units. The
dosing is effected automatically acc. to the requirements arising during the wash process.
Use of unsuitable products will significantly impact the service life of the dosing equip-
ment.
We therefore recommend that detergents should have a pH value greater than 7 and
that rinse agents should have a pH value between 7 and 2.

Operation during washing and rinsing cycle

The following fundamental principles must be observed when placing the items to be
washed in the baskets:
 All hollow containers must always be loaded upside down. Otherwise the water will be
trapped inside and they will not dry to a brilliant finish.
 Plates, trays and big plates should always stand at a slight angle in the basket. The
inside faces pointing upwards.
 When using cutlery baskets, ensure that cutlery is always inserted handle down.
 Load the cutlery baskets with a mixture of spoons, knives and forks, as identical items
of cutlery can be too close together.
 Do not overload the cutlery baskets.
 Do not stack the dishes in the wash basket directly on top of each other. As the wash
water could not strike the items directly and unnecessarily long wash times would have
to be selected. Short wash times with baskets which are not overloaded are much more
economical.
