Connections To Be Made By The User; Water And Gas Supply; Electric Supply; Preliminary Operations - Rancilio classe 8 User Manual

6.1. Connections to be made by the
user
Hook-up must be carried out by qualified
personnel in full accordance with federal,
state and local regulations.
6.1.1. Water and gas supply (Fig.5)
Connections must be installed close to the machine.
• Water drainage pipe 1, having a minimum internal
diameter of 30 mm, equipped with a water-trap
accessible for inspection.
• Water supply pipe 2, with a 3/8"G cut-off tap.
Make sure that the maximum supply pressure
does not exceed 6.5 Mpa; otherwise, install
a pressure reducer.
6.1.2. Electric supply (Fig.5)
The machine is supplied ready for connection according
to the required electrical specifications.
Before connecting the machine ensure that the plate
details comply with those of the electric distribution
network.
The electrical connection cable must be directly con-
nected to the connection provided according to
current legislation. Ensure that the grounding system
is efficient and in compliance with current legal re-
quirements.
The grounding system and the lightning protection
system must be realized in accordance with the pro-
visions of current legislation.
For the supply network use a cable in compliance
with standards with protective conductor (grounding
wire).
For three-phase power use a cable with 3 conductors
( 3 phases + neutral + ground).
For single phase power supply use a cable with 3
conductors (phase + neutral + ground).
In both cases it is necessary to provide an automatic
differential switch (Fig. 5) at the start of the power
cable, complete with magnetic release elements in
accordance with the identification plate details (Fig.
1). The contacts must have an opening of equal or
over 3 mm and with dispersed current protection of
30 mA.
Remember that each machine must be fitted with its
own safety elements.
WARNING:
Should the power supply cable be damaged
it is to be replaced by the manufacturer or by
its technical assistance service or by person
with equivalent qualification, in order to
prevent any risks.
6.2. Preliminary operations (Fig.6)
P O T E N T I A L - E Q U A L I Z I N G
CONNECTION
This connection, which is the one called for by several
norms, avoids electrical potential differences, building
up between any equipment that may be installed in
the same room. There is a terminal clip on the under
side of the base of the machine to which an external
potential-equalizing wire should be connected.
This connection is ABSOLUTELY NECESSARY and
must be made right after the machine is installed.
Use a wire whose cross-sectional area conforms to
the existing norms.
6.3 ANTISUCTION
INSTALLATION (Fig.7)
On the top of the boiler there is the antisuction valve.
When installing the machine make sure to remove
the plastic fork "A" and check that the pin "B" is
not blocked.
This operation is very important for the correct
working of the machine.

6.4. Connections

• Place the machine on the horizontal surface
previously prepared.
Before connecting, thoroughly wash the mains water
pipes:
• Leave the water supply taps running at full pressure
for several minutes.
• Connect to the mains water supply.
• Connect the machine to the socket.
Thoroughly wash all the water pipes of the machine:
• Leave the water supply taps running at full pressure.
• Switch on main switch 1 (Fig.8): wait until the boiler
fills up to the level set.
• Switch on boiler resistance switch 2 (Fig.8) to begin
heating the water in the boiler.
• Operate each unit in order to allow the water to
escape for about one minute; repeat the operation
twice.
• Deliver steam from the steam jets for about one
minute.
• Deliver hot water for about one minute; repeat the
operation twice.
• Switch off switches 1 and 2.
• Empty the water from the boiler: see point 10.3.1.
IMPORTANT
Should the machine not deliver water for over
24 hours, wash the internal components be-
fore beginning work, repeating the operations
as described above.
