Note
All filling connections are 3/8 male gas type. The
drain tray is connected with a pipe of 16 mm. inter-
nal diameter.
Warning
The water mains must provide cold water for human
consumption (drinking water) at a pressure between
1.5 and 5 bar. If the pressure is greater than 5 bar,
connect a pressure reducer upstream from the
pump.
Place a tap (8) and a one-way valve (9) ) on the water
mains so that it will be possible to cut off the water
to the machine.
Connect the water mains (2) directly to the machine
inlet (6); if you want to install a softener (11), con-
nect the water mains (2) to the softener inlet and the
softener outlet to the machine entry (6).
To prevent the water from freezing, install a softener
(11) only where the room temperature is more than
5°C.
When connecting the machine cup to the sewer
drain tray to the sewer drain, avoid tight curves or
kinks and make sure that there is a sufficient incli-
nation for water to flow out of the drain.
The drain must be connected to an inspectionable
siphon that can be periodically cleaned in order to
avoid the backflow of unpleasant odours.
To avoid oxidation and damage to the machine over
time, do not use iron fittings for the hydraulic con-
nection, even if they are zinc plated.
Attention
The hydraulic connection must be made in com-
pliance with local national rules.
If an external tank is used the connection pipe bet-
ween the machine and the tank must not exceed 150
cm.
For the European Community: for both hydraulic
connection to the water mains as well as the con-
nection to the external tank, a one-way valve (9)
must be placed upstream of the machine as indica-
ted by the standards EN. 1717.
Note
All the machines are equipped with an automatic
water filling with a time control device which allows
the boiler to be filled with water within a maximum
period of time. This function keeps water from co-
ming out of the boiler valve (flooding) and prevents
the overheating of the power pump. If the period of
time does not last enough to fill up the boiler com-
pletely, switch the machine off and on again and re-
peat the above mentioned operations.
5.4. Electric connection
Before using the machine, ensure that the network
power comply with the data provided on the plate pla-
ced under the drain tray.
Connect the machine plug to the electric network.
Attention
It is recommended to install a protection
switch.
5.5. Start procedures
Switch the machine on using the main switch (A).
Before using the machine, wait for (10 minutes) or until
the pressure gauge (B) shows the good working pres-
sure (1-1,2 bar).
