5.9 Dual scale pressure gauge (Fig.
13)
(where expected)
The machine is equipped with dual scale pres-
sure gauge by which you can check the following
pressures:
Boiler manometer (Fig. 13 - A)
range 0~3 bar (0~0,3 MPa)
The boiler manometer indicates the boiler pres-
sure.
Pressure gauge (Fig. 13 - B)
range 0~15 bar (0~1,5 MPa)
The pressure gauge indicates the pump maximum
pressure during operation. When the motor pump
is stopped the manometer indicates the water
supply pressure (R version) or "0" (S version).

6 - MAINTENANCE

To allow the machine to work correctly, follow the
maintenance instructions provided below.

6.1 Safety rules

Do not subject the machine to water jets.
Disconnect the machine from the electrical power
by turning the electrical power network omnipolar
knife-switch lever to the resting position 0. Remove
the plug and close the water interception tap
before carrying out maintenance and/or cleaning
work. If the machine is malfunctioning, do not
attempt to repair it alone and call the technical
assistance service immediately. If the electrical
power cable has been damaged, turn off the
machine immediately, turn off the water and call
the technical assistance service. Do not replace

6.2 Cleaning the machine

These recommendations are indicative.
Maintenance and cleaning frequency depends on
machine use.
After each use
1) Clean the steam nozzle.
2) Clean the filter holder and filters
Daily
1) Clean the cup holder grill and drain tank
2) Clean the machine body
Weekly
1) Clean the unit seal with the brush provided (Fig.
07).
2) Clean the water tank (S VERSION).
3) Wash the unit as follows: attach the filter holder
to the unit with the blind filter provided (Fig. 10;
pos. 17) and start up distribution several times.
Monthly
1) Submerge the filter holders and filters in boiling
water for a few minutes to dissolve coffee grease,
use a cloth or sponge to remove residue.
Do not use solvents, detergents or
abrasive sponges for washing and
cleaning. Clean the machine body with
a cloth dampened in water and/or
neutral detergents, carefully drying surfaces before
reconnecting the machine to the power supply.
Use water to clean the cup holder grill and drain
tank. Use water and neutral detergents to clean the
tank after removing it. When finished rinse
thoroughly. Replace the tank and insert the silicon
tubes making sure that the suction pipe touches
the bottom.
6.3 Safety thermostat - Manual re-
arming
Warning!
The operation described below
is only relevant to an installing
technician who is authorised by
the manufacturer.
While the machine is working, the boiler resist-
ance may overheat and, cutting off power, sets
off the safety thermostat that prevents any further
damage to the boiler. To restore normal opera-
