Basic information on the small machine
Each machine is manufactured according to state of the art technology.
Operation is safe.
Dangers could arise from this model if it is incorrectly operated by
unsuitable operating staff or if it is not used for the purpose intended.
Liability
We accept no responsibility for damage to the appliance and other
objects caused by operating faults or by failure to observe the operating

and all product liability.
4.1 General description of the model
4.1.1 Type
Square basket appliance with stationary basket.
4.1.2 Wash principle
The appliance has one wash and one final rinse cycle.
The temperature regulator maintains the wash temperature. A
centrifugal pump moves the water from the wash tank into the wash
nozzles. The water jets hit the items to be washed from different
directions. This guarantees an even wash.
The washing cycle is followed by the fresh water final rinse. The items
are rinsed via a separate nozzle system with hot fresh water (dish
washers approx. 80 - 83° C, glass washers approx. 62 - 65° C). This
also heats the items for the subsequent drying process. At the same
time the final rinse water is used to regenerate the wash water, thus
reducing the level of contamination of the wash water.
4.1.3 Detergent dosing
Liquid alkaline detergent is automatically added by a built-in dosing unit.
The detergent is moved from the container into the wash tank by means
of a hose line. The exact dosing of the detergent is guaranteed by a
time switch.

Operating instructions Basic small machine information

4.1.4 Rinse aid dosing
Liquid rinse aid is added into the final rinse system by an integrated
dosing unit. The exact dosing of the rinse aid is guaranteed by a time
switch
The instructions for operating and adjustment of the dosing units can be
found in the ”Service Instructions“.
4.2 Use for the purpose intended
The small machine must only be used for the purpose intended.
The dish washing machine is intended for washing dishes and cutlery.
The glass washing machine is intended for washing drinking glasses.
4.3 Improper use
Small machines and especially switch boxes and other electrical-
technical components must not be sprayed with a water hose or a high-
pressure hose.
Do not place any solvents or other easily flammable substances in the
washing-up area, as this increases the danger from explosions
The water in the washing-up area is not drinking water! Do not use the
water from the wash-up area for food preparation or drinking!
Do not place anything on the open door of the appliance, especially no
heavy loads, as the machine could tip over.
The door must be opened very carefully during the wash cycle to reduce
the risk of wash water splashing out of the appliance.
Steel pan scrubbers must not be used for pre-scouring or for cleaning
the items to be washed.
Do not wash any metal items which are not made of stainless steel in
the machine.
The entry of metal particles (especially iron, tinplate, copper) MUST be
prevented.
The appliance must not be used to transfer waste water from other
sources into the drain (warning: risk of corrosion and blockage).
Only use suitable products for cleaning the stainless steel surfaces.
These must not attack the material, form any deposits, nor cause any
discolorations.

2.4 Operation during washing and rinsing cycle
The relevant lights indicate when the appliance is ready for operation. (see also
illustrations in chapter 2.1)
The following fundamental principles must be observed when placing the items
to be washed in the baskets:
 All hollow containers must always to be loaded upside down. Otherwise the
water will be trapped inside and they will not dry to a brilliant finish.
 Plates, trays and serving dishes should always stand at a slight angle in
the basket with their 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 cannot 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.
2.4.1 Start the wash cycle
Program start key
 Place the items in the basket.
 Place the basket in the appliance, ensuring that it is correctly centred.
 Close the door.
 Press the program start key.

The wash time can differ from the set program time if the boiler heating capacity
is not sufficient for heating up the fresh water to the pre-set boiler temperature
during the program time. In this case the automatic wash time extension will be
activated.
2.4.2 Remove the washed items
 When the light goes out, open the door and remove the basket.
3 Shutting the machine down
OFF-key
Program start key
 Press the ”0“-key (OFF-key). The machine is switched off when all the lights
are out.
 Press the program start key to drain the tank.

Operating instructions Care and Maintenance
FV 40.2
- 6 -
 The cleanliness of final rinse nozzles must be checked weekly and if
necessary clean under running water.
The inserts for final rinse nozzles must be inserted with the prongs facing the
direction of the water flow.
4.5 Maintenance of stainless steel surfaces
The appliance is made of high-quality stainless steel. Nevertheless, under
certain conditions corrosion may appear.
To maintain stainless steel surfaces permanently free from corrosion
 use only cleaning products which are properly suited.
Use only products which do not attack the material, build up a film or cause
discoloration.
4.6 De-scaling
If the appliance is operated with hard water, scale can build up in the boiler and
wash tank, making it necessary to de-scale the tank interior, the tank heating
equipment, the boiler heating equipment, the items to be washed.
Use only products suitable for industrial dishwashing machines to de-scale the
appliance. When using these products please observe the manufacturer’s
instructions.
After de-scaling:
 Flush the de-scaling product completely out of the appliance. 1 or 2 rinse
cycles with fresh water are necessary to achieve this.

5 Machine with built-in AktivClean water softening
device.
5.1 General
The built-in ActivClean water softening device operates automatically. All that is
necessary is to replenish the salt from time to time. The regeneration water is
fed directly into the drain. It is not necessary to drain the tank during the
regeneration process.
The temperature of the feed water must not exceed 50° C.
5.2 Adjustment of water hardness
The water softening device is pre-set to 30°Gh in the factory. When the service
engineer installs or commissions the appliance he should adjust this value
depending on the actual water hardness. Should there be any further changes
in the water hardness, this parameter must be adjusted accordingly as set out
in the Short Programming Instructions.
