The machine is provided with some special controls which allow following operations:
• Front panel LED test
•
Descaling boiler
• Calibration of soluble product specific weight
• Access to the special controls:
•
Switch the machine off, open the front door panel and override the sensor switch (7) by inserting the
“orange key “(8). Switch the machine on by the main switch pressing simultaneously the reset button.
•
The first 5 green LEDS will illuminate while the signals “Ready for use” and “Water empty” blink alte
rnatively
• Front panel LED test:
.
Once the “Access to the special controls” procedure has been performed, press the first upper selection
button and then one by one all buttons next to the green LEDS. At the end of the test, all red LEDS next
to the selection buttons will illuminate.
• Descaling
(for machines with water tank only):
• Fill the water tank with about 1 liter of approved descaling solution following the relevant instructions
printed on the packaging.
• Once the
“Access to the special controls” procedure has been performed, press the second upper selec-
tion button (beverage B) to activate the descaling program.
• The descaling solution (about 400 cc.)is automatically pumped into the boiler and remains here at an
ideal temperature of 40
°
C for about 15 minutes. After this time, the waste solution is discharged and
new solution is pumped into the boiler, where it will remain for 15more minutes . During this period,
remove the tank, rinse it well and fill it with fresh water. After 15 more minutes, the system is
automatically filled with fresh water and the machine turns automatically to the starting condition.
• Take the “orange key” (7) away and close the door. The machine is now ready to work.
• Calibration of soluble product specific weight:
•
At the factory the machine is set on the average specific weight of the soluble products found on the
market. However for a perfect correspondance between the programmed and the dispensed product
weights it’s possible to perform a more accurate calibration.
• Once the
“Access to the special controls” procedure has been performed, press the 4th upper selection
button (D) . The green LEDS of the last 3 products corresponding to the relative soluble product bin will
illuminate. Set a cup under the soluble product dispenser press the corresponding selection button and
calculate the average of the weights obtained after a few cycles. Enter this value into the D.A. 7P using
the 7P programmer (See “Instruction manual” Par.3.2).
