6.1.1. Safety Signs
To conduct correct maintenance and cleaning operations, it is indispensible to take into consideration the indications reported below.
During interventions, it is necessary to signal machine intervention using specific signs (these signs are positioned in such a
manner to prevent any undesired intervention on the machine).
During the interventions only authorised staff can access the work area.
ATTENTION:
DANGER:
All the materials with environmental impact which must be eliminated after maintenance interventions must be disposed of according to norms in
force.
ATTENTION:
In any case, to conduct all the maintenance and cleaning operations reported below on the machine, the following Individual
Protection Devices are necessary:
6.1.2. Verification of Material Availability
With an advance of at least 60 days from the fixed date for maintenance interventions, conduct a detailed examination of the
necessary material:
1.
check the material is in the warehouse,
2.
if necessary, ask the manufacturer's Technical Office for the missing pieces, at least 30 days in advance.

6.2. Emergency system

DANGER::
DANGER:
.
If a functioning fault or anomaly occurs on the electronic central unit and immediate replacement is not possible, the EMERGENCY
SYSTEM can be used to maintain the unit operational until the central unit is replaced. To use this system, having sectioned the
machine, proceed as follows:
1.
Remove all bridges on the L terminals and the common ones on the board relays (terminals 25-28- 33-36-38);
2.
As reported in the diagram in Figure 6, connect a thermostat between terminal L, the NO terminals (terminals 32,37) and the NC
terminal (terminal 34) of the relays on the compressor, defrosting and fans (COMP, DEF and FAN).
3.
Then make a bridge between the L terminals and the NO terminal of the ON/OFF relay (terminal 26 for power supply of the
tolerance on the carter, door and drainage where present).
4.
Connect the Blocksystem FS again to the power line and set the thermostat to the desired temperature.
DANGER:
ATTENTION:
When installing the new central unit, restore all the connections described in points 2, 3, 4 and 5.
5.
the maintenance and cleaning operations must only be conducted by expert and specialist staff that have
read and understood all the indications reported in this Use and Maintenance Handbook.
only dismantle the parts of the machine actually necessary to conduct the specific maintenance operation.
Furthermore, before re-delivering the machine to operators, it is necessary to verify its integrity and
functionality.
to dispose of materials with high environmental impact, if necessary, appoint specialist structures.
for the machine, only operators correctly trained and informed on the risks present can intervene on the
machine and only having fully read this use and maintenance handbook. The manufacturer declines all
responsibility for any damage to property and/or persons deriving from improper interventions conducted
by unqualified, untrained or unauthorised staff.
before conducting any planned cleaning interventions, ensure the machine is sectioned from the power
supply, and any hot surfaces have cooled.
what we've described is a temporary connection! As soon as possible contact the vendor or directly contact
the manufacturer to replace the non-operating board.
during the entire emergency phase, defrosting is excluded, therefore we recommend you reduce opening
the coldroom to a minimum.
