General information and safety regulations
3.7.4.2 Special attention to be paid during
maintenance and dismantling
During maintenance and dismantling, special attention
must be paid to the operations described below.
Always carry out the required operations using com-
pliant tools and always pay the utmost attention to
elements that could lead to tripping or cause cuts and
bruises. Always wear appropriate PPE.
Maintenance and dismantling/disposal operations
must always be carried out by qualified and specially
trained personnel.
Check that supplies, signals (where applicable) and
power have been suitably cut off and that no one can
reactivate them before completing maintenance
(including cleaning) and decommissioning. Also
check that any residual energy from the heat transfer
fluid has been discharged before proceeding with any
operation.
Operate on the machine/partly completed machinery
and on the relative piping after having emptied them
from the refrigerant gas and carry out the vacuum
operations before restarting the machine.
Restore the positioning of the protective fan grilles
once the machine maintenance is finished, as rotating
parts can cause impact, entanglement, abrasion,
shearing and suffocation.
Do not insert fingers or objects through the protective
grilles of the fans or at the sides of the air ducts.
Do not work on the machine with bare feet or without
suitable PPE, or with wet or damp hands.
Do not use water jets to wash either the inside or
outside of the machine.
Before restarting the machine, after maintenance or
cleaning operations, check that you have not left any
tools inside the machine. Check the tightening of the
movable or openable parts and reposition all the
safety devices removed, as well as check for the
absence of refrigerant fluid leaks. Also check the
correct positioning of the ballcocks and shut-off
valves.
Before carrying out any cleaning operation, discon-
nect the machine from the mains power supply.
Never use gasoline, solvents or other flammable fluids
for cleaning parts, only use approved, non-toxic and
non-flammable detergents.
Do not make any modifications or alterations to the
machine/partly completed machinery that could com-
promise its safety and without first having contacted
and obtained written authorisation from the manu-
facturer.
