ADJUSTMENTS AND SETTINGS
The following adjustment and setting operations may be carried exclusively by qualified
and authorised personnel, paying the utmost care and attention, and taking all
precautions in the event that safety features are bypassed.
6.1
Dispenser
Before the
zeroing
operation may be carried out,
dispenser(s) and supply pipes must be filled up. The
zeroing is performed via the adjusting screws which may
be reached by removing the front panel underneath the
tank door.
•
The warranty does not cover damages resulting from improper use of the
dispenser(s) or incorrect manual feed.
•
Type and dosage of detergent and rinse agent are crucial in affecting the
appliance’s performance and service life. Use only liquid products for industrial
washing with antifoaming agents.
•
Adjustments must be made with the appliance hot and correct amount of
washing product.
6.1.1 Rinse agent dispenser
The level of rinse agent inside the container must be adequate; it must never be
completely emptied, or topped-up with corrosive or impure products. To fill up the supply
pipe and the dispenser, turn on the appliance and start the washing cycle, wait for
approx. 20 seconds and press the “On/off” button
for 8-10 times with intervals of
approximately 10 seconds. Leave it pressed to let the cycle terminate.
•
Turning the adjusting screw anticlockwise, reduces
the quantity of rinse agent released, while turning it
clockwise, increases the dosage.
•
For a rough estimate concerning the amount of rinse
agent required for the first zeroing operation, refer to
the dosage suggested by the manufacturer of the
product.
•
The screw adjustment must be refined on the basis of
the results obtained after at least three rinsing cycles,
so to let the system settle.
•
Striations on washed items and the formation of foam within the washing solution indicate an
excessive quantity of rinse agent. Items covered with water drops and long drying time, indicate
