In the case that residuals are present, check that:
• the washing jets are clean
• there is detergent
• the pump suction filter is clean
• the positions of the objects in the rack are
correct.
DISHES POSITIONING
It is suitable to place dishes, inside the plastic
basket with the concave side facing upwards.
Place mixed cutlery in a vertical position into the
suitable container minding not to cram them and
with handgrips towards the bottom (see drawing).
CLEANSING AGENTS
Choice of the suitable cleansing agent is an
essential condition if you want to obtain
extremely good washing results as regards
hygienic results. It is then important to consider
some points. First of all only highly alkaline and
chlorine-active antifoam products, especially
made for industrial dish-washing machines, must
be used and they must be produced by well-
known reliable Firms. Mean concentration of the
cleansing agents in powder must be 1,5÷2,5 g/lt.
Mean concentration of liquid cleansing agents
must be 2÷4 g/lt.
In order to avoid scales and corrosions, put the
cleansing agent above water level on the nearest
area of the sucking pump filter, in this way it will
immediately dilute and will not deposit on the
tank bottom.
RINSING ADDITIVES
To grant a perfect rinsing, a quick drying and to
avoid calcareous sediments on glasses and cups
you must add a surfactant on water (Brightener).
Your cleansing agent supplier will be able to
suggest the most suitable product. Your machine
is equipped with a rinse aid dispenser. Mean
concentration used is 0,15 g/lt.
REGENERATING
(for machines with Water softener)
If the glass washer is equipped with a Water
softener it is possible to
regenerate
the resins.
When this operation is needed, the
“D”
lamp blinks
slowly.
To perform the REGENERATION operation, lift
the overflow out of the tank and close the door .
Push the
"B"
button fot three seconds until the
"D"
lamp is lighted. After twenty (20) minutes the
"D"
lamp is OFF.
The regeneration of resins has been completed
automatically and the machine is ready to operate
again.
After 45 washing cycles, this signaling is implicit.
According to the water hardness, it is possibile to
modify the programming of the regeneration. See the
corresponding table in the installer section.
SALT CONTROL
When it is necessary to add salt in the container, the
“D”
lamp blinks quickly.
This operation is programmed to be performed every
10 regeneration cycles.
Unscrew the plug of the salt container at the
bottom of the tank and put 1 kg coarse salt tablets
in it. Clean the gasket and screw the plug.
After having added the salt into the container, perform
the REGENERATION operation by following the
instructions indicated in the previous paragraph.
Attention!
The lack of salt in the container damages the
machine because of limestone, besides a defective
washing of glasses and dishes.
These damages are not covered by the warranty.
DRAIN PUMP INSTRUCTION
(only for machines with drain pump)
The drain pump starts up automatically just
during the washing cycle
to discharge the
exceeding water coming from the rinsing cycle.
At the end of the working day, in order to
completely discharge the tank,
it is necessary
to perform the following operations:
1. Open the door of the dishwasher
2. Remove the overflow pipe from the tank;
3. Afterwards push button
“R” for 3 seconds.
(the lamp
"H"
is lighted).
The discharge will stop automatically after 5
minutes. The control lamp will stop flashing.
Reinstall the flow over and shut the door.
