Turning Off The Machine; Water Replacement - Wega ALE Series Use And Maintenance Manual

6.9.3 Gas heating (where included)
Turn the power switch (A) to position 1;
open the gas valve (B) on the mains;
hold down the push button (C) and, at the same time,
press the on button (D). Once the flame ignites, hold
down knob (C) for a few seconds, to allow proper
activation of the thermocouple;
then check through the window (E) that the flame
has ignited;
wait for the operating pressure indicated on the
pressure gauge to reach a working value of 1-1.2 bar.
B A
6.9.4 Electric heating (if included)
Proceed as indicated in the previous paragraph;
after checking that the flame has ignited, turn the
main switch (A) to position 2. In this way the boiler
heating element is powered and operating pressure
will be reached more quickly;
wait for the operating pressure indicated on the pres-
sure gauge to reach the working value of 1-1.2 bar.
Do not operate the gas system when the boiler is empty.

Water replacement

6.11
During the installation of the machine, the Qualified
Technician must replace the water contained in the hy-
draulic circuits by following these steps:
when installation is complete, the appliance has to
be started, brought to the nominal working condi-
tion and left for 30 minutes in the "ready to operate"
condition;
afterwards, the appliance has to be turned off and
emptied of the first water introduced in the whole hy-
draulic circuit, to eliminate possible initial impurities;
then, the appliance must be once again loaded and
brought to the nominal working conditions;
after reaching the "ready to operate" condition, the
following has to be performed:
- for each coffee unit, carry out continuous dispens-
ing, in order to release at least 0.5 liters of the cof-
fee circuit. In the case of several dispensing points
matched with the same exchanger/coffee boiler,
divide the volume on the base of the number of
the dispensing points;
- release the whole volume of hot water inside the
boiler (3 liters for 1GR, 6 liters for 2GR, 8 liters for
3GR, 11 liters for 4GR), by performing a continu-
ous dispensing from the appropriate nozzle. In
the case of several dispensing points, divide the
volume on the base of the number of the dispens-
ing points;
- continuously release steam for at least 1 minute
for each steam dispensing point.
If the machine remains inactive for a time longer than 1 week, the
Qualified Technician must renew 100% of the water contained in
the hydraulic circuit, as indicated above.
Before using the machine, perform dry runs with the filter
holder attached for a few seconds to release any air which may
be in the circuit, so that the dispensing groups are completely
heated;
before using the machine, dispense a few servings of coffee to
test the grinding and to check the operating pressure of the
machine;
during dispensing of coffee, do not remove the filter holder
from the brewing.
