10.3.1. Renewal of water in the boiler
models CLUB PU - ME (Fig,13)
To be carried out only by qualified personnel.
● Turn off the machine and wait for the pressure in
the boiler to diminish (gauge needl on "0").
● Insert a rubber hose into the hose-end fitting (3)
(Fig.13)
● Use the wrench (1) to immobilize the fitting (2) and
loosen the hose-end fitting (3).
● Allow the water to flow out completely; then, close
the fitting (3) and remove the rubber hose.
● Refill the boiler (paragraph 7.3.).

10.3.2.Renewing the water in the boiler

models ME (excluding CLUB ME - ME).
Operation to be carried out when the machine
is on and under pressure.
● Draw the water from the boiler by pressing the
delivery control key 6 Fig.8;
● Repeat this operation several times to enable an
adequate change of water;
● Wait until the correct operating pressure has been
reached (guage needle Fig.8 on green area)) be-
fore making coffee.
10.3.3. Regeneration (Fig.14)
Model CLUB PU/S - ME
Operation to be carried out when the machi-
ne is off and cold and with the plug discon-
nected.
To be effected after the consumption of approx.15
litres of water (average hardness calculated as 35
degress on the French scale) or at least once a
month.
● Prepare a solution in a glass of water adding three
teaspoons of fine salt (the salt must be properly
dissolved).
● Drain the water-tank, see point 10.2.
● Slide the softener 1 Fig.14 off the rubber tubing 2
and turn it over.
● Pour the solution through the filter and the resin,
letting it flow down freely.
● Wait about 5 minutes, then hold the softener under
a tap and rinse it with water. When the water coming
out of the softener is no longer salty, the resins are
regenerated and the softener is ready for use once
again.
● Put the softener back on the rubber tube and
replace it horizontally on the bottom of the tank.
● On completion of this operation, the machine can
be started up again by repeating the procedure
described in paragraph 7.3.

This table has been drawn up according to a water har-
dness of 25 degress calculated on the French scale.
See the documentation included with the softener
for the instructions for use.

11. STOPPING THE MACHINE

A - Temporary stop
● Carry out cleaning and maintenance operations.
● Wind up the cable and fasten it to the machine
