Before carrying out any operation on the machine en-
sure that the plug is disconnected from the current and
that the machine is cool.
In order to avoid any electric shocks, electrical parts and
surrounding components must not:
- enter into contact with any type of liquid;
- be manipulated by humid or wet hands;
- be tampered with.
It is forbidden:
- to use the machine near flammable substances and/or
explosives and/or in an atmosphere with any risk of
fire;
- to use unoriginal spare parts;
- to carry out any type of technical modification not co-
vered in the normal procedures of diagnosis and re-
pair.
In case of fire, use carbon dioxide (CO
2
). Extinguishers.
Do not use water or powder extinguishers.
If an operation or intervention not foreseen should be
carried out, following a different procedure than that in-
dicated in the manual, please contact Lavazza technical
service before starting.
Structural damage, modifications, tampering, alterations
or improper repairs could compromise the safety of the
machine.
Attention
Any operation taken by the technician on the elec-
tronics of the machine when the machine is powe-
red, automatically invalidates any guarantee. The
technician should know that the machine is electri-
cally connected and act accordingly.
2.1. Stop functions
La macchina si arresta portando l’interruttore generale
su “0” (OFF).
2.2. Safety devices
The machine/s described in this publication, are desi-
gned in compliance with the specific standards in force
(CEI EN 60335-1) and therefore have measures of pro-
tection in all the potentially hazardous parts.
A thermal protector avoids any overheating of the
boiler.
A 150°C safety valve
ensures that the pressure in the
boiler does not exceed 2 bars.
Attention
Do not change, eliminate or by-pass the safety de-
vices in order to not cause serious risks to health
and safety.
2.3. Residual risks
The careful hazardous analysis performed, has allowed
most of the risks connected with operating and mainte-
nance machine conditions to be eliminated. Lavazza re-
minds the user that the instructions, procedures and
recommendations contained in this manual should be
strictly followed, and comply with the safety rules in
force, including the use of provided protection devices,
both integrated in the machine and individual.
This chapter illustrates the risks that the user may incur
if he does not comply with the specific safety rules as
described in this booklet.
- La machine must be connected to an earthed installa-
tion.
If it is not done, the appliance can become a source of
dangerous electrical discharges as it is no longer able
to discharge electricity to earth.
- Be careful with the hot water and steam pipes (only
LB2801 and LB2811 models).
During use the hot water pipe may overheat, thus be-
coming a source of danger.
Handle these parts carefully .
- Never direct steam or hot water jets directly on parts of
the body.
- Be careful with the outer surfaces of the brewing unit.
During normal operation, the brewing unit also over-
heats, thus becoming a source of potential hazard. Be
careful not to come into contact with the outer surfa-
ces of the brewing unit.
- Do not work on the machine when it is powered.
Before carry out any operations on the machine, di-
sconnect it from the electrical network.
- Do not use water jets for washing any part of the ap-
pliance because running water can seriously damage
electrical and electronic components.
- Never work on the hydraulic system before having em-
ptied it.
All operations regarding the hydraulic system and its
boiler have to be avoided when there is still water and
pressure in the system. You must therefore empty it
beforehand, closing the mains tap and dry-running the
brewing unit, hot water pipe, cappuccinatore or steam
pipe for a short time .
Switch the machine off.
When the pressure is at zero, completely empty the
boiler, by opening the specific valve located on the
lower part of it. If the above procedure is not correctly
