POWER REGULATOR AND WORK THERMOSTAT
• Remove the control panel and replace the component.
SAFETY THERMOSTAT
• Remove the control panel and the front panel and replace
the thermostat.
NOTE: Remove the tank front panel to access the thermostat
bulb. Take care with the capillary tube and bulb, which must
be positioned in the special seats.
3.8.3 MAINTENANCE INTERVALS
The inspection and maintenance intervals depend on the
actual machine operation conditions and ambient conditions
(presence of dust, damp, etc.), therefore precise time intervals
cannot be given. In any case, to minimise interruptions of
the service, careful and periodical machine maintenance is
advisable.
It is advisable to stipulate a preventive and scheduled
maintenance contract with the after-sales service.
3.8.4 MAINTENANCE FREQUENCY
In order to guarantee constant machine efficiency, it is
advisable to carry out the checks with the frequency given in
the following table:
MAINTENANCE, INSPECTIONS,
CHECKS AND CLEANING
FREQUENCY
Routine cleaning
Daily
General cleaning of machine and
surrounding area
Cleaning internal parts
Every six
months
Check condition, and for any deformation,
loosening or removed parts.
Control
Yearly
Check mechanical part, for any breakage
or deformation, tightening of screws.
Check readability and condition of words,
stickers and symbols and restore if
necessary.
Machine structure
Yearly
Tightening of main bolts (screws, fixing
systems, etc.) of machine.
Safety signs
Yearly
Check readability and condition of safety
signs.
Electrical connection cable and plug
Yearly
Check the connection cable (replace it if
necessary).
Extraordinary machine maintenance
Yearly
Check all gas components
The machine is designed and built for a duration of about 10
years. After this period of time (from machine commissioning)
the machine must undergo a general overhaul. Some
examples of checks to be carried out are given below.
- check for any oxidised electrical components or parts; if
necessary, replace them and restore the initial conditions;
- check the structure and welded joints in particular;
- check and replace bolts and/or screws, also checking for
any loose components;
- check the electrical and electronic system;
- check the functionality of safety devices;
- check the general condition of protection devices and guards.
ATTENTION!
Machine maintenance, checking and overhaul
operations must only be carried out by a
specialised Technician or the After-Sales
Service, provided with suitable personal
protection equipment (safety shoes and gloves),
tools and ancillary means.
ATTENTION!
Work on the electrical equipment must only be
carried out by a specialised electrician or the
After-Sales Service.
3.8.5 DISASSEMBLY
If the appliance has to be disassembled and then reassembled,
make sure the various parts are assembled in the correct
order (if necessary mark them during disassembly).
Before disassembling the machine, make sure to carefully
check its physical condition, and in particular any parts of the
structure that can give or break. Before starting disassembly:
- remove all the pieces (if present) in the machine;
- disconnect the power supply;
- enclose the work area;
- display a sign indicating that the machine is undergoing
maintenance and not to carry out manoeuvres;
- carry out the disassembly operations.
ATTENTION!
All scrapping operations must occur with the
machine stopped and cold and all the energy
sources (water, gas electricity) disconnected.
ATTENTION!
To carry out these operations, appropriate PPE
must be used.
ATTENTION!
During disassembly and handling of the various
parts, the minimum height from the floor must
be maintained.
3.8.6 DECOMMISSIONING
If the machine cannot be repaired, carry out the
decommissioning operations, signalling the failure with a
suitable sign, and request assistance of the manufacturer’s
after-sales service.
