Descaling
This procedure is designed for use with liquid
descaling "PULYDESCALER espresso".
For the descaling cycle, perform the following
steps:
If the machine is in "Water Mains", mode, it must
be switched to internal tank (see specific paragraph);
• turn on the machine and bring it to working
condition: the gauge should show a pressure of
1-1.2 bar;
• place under all coffee spouts a large pitcher and
make sure the levers of the groups (F) are closed;
• fill the tank with a solution of 125 ml of "PULY-
DESCALER espresso" and 400 ml of water at room
temperature;
• remove the upper grid
(H)
so as to gain access to
the descaling switch
(E)
;
• set the switch
(E)
in position 1; the corresponding
LED (G) lights up to indicate that the machine is
configured for the descaling;
• replace the top grid;
• perform a series of 30-second deliveries, al-
ternated by another 30 second pause on both
dispensing units, until the tank containing the
solution of detergent will be emptied completely;
• remove and wash the tank with water;
• fill it with 4 liters (tank full) of clean cold water
and put it back in place;
• perform another series of deliveries on all dis-
pensing units, until the tank will be emptied so
as to perform the complete rinsing;
• remove the upper grid (H) and return the descal-
ing switch to position
(0)
, then replace the grill.
• At this point, the procedure is complete; if you
want, you can reconfigure the machine to be
fed by the water mains; otherwise, if everything
is left unchanged, it will continue to be fed by
the inner tank.
If during the dispensing is blocked during the
procedure, check if the LED
(G)
is on. If it is off, return
the machine to working conditions by performing
these steps:
• make sure that the levers of the groups (F) are in
the closed position;
• remove and wash the tank with warm water,
then fill it with clean cold water and put it back
in place;
• return the descaling switch
(E)
to position
(0)
;
• return the machine to working condition: the
gauge should show a pressure of 1-1.2 bar;
• repeat the descaling procedure again if not com-
pleted; otherwise, it will be sufficient to carry out
the rinsing only.
