• illegiblemarkingsandsignsmustbecorrected;
• thepipeorrefrigerationcomponentsmustbeinstalledinapositionwhereitis
improbable that they are exposed to substances that could corrode the components
containing the refrigerant, unless the components are manufactured with intrinsically
corrosion resistant materials or are appropriately protected from corrosive agents.
i. Check the electric devices
The repair and maintenance interventions of electric components must envision initial
safety checks and component inspection procedures.
In the case of a fault which may compromise safety, no electric power supply must
be connected to the circuit until it has been suitably repaired.
If the fault cannot be repaired immediately, but the operation must be continued, use
a suitable temporary solution.
This solution must be communicated to the owner of the plant so that all parties can
be informed.
The initial safety controls envision:
• drainingthecondensers:thisoperationmustbeperformedsafelytopreventthe
possible formation of sparks;
• noexposureofcomponentsandelectricwiringtovoltagesduringloading,repair
orpuricationofthesystem;
• thecontinuityoftheearth.
l. Repair interventions of the hermetic components
• Duringtherepairofhermeticcomponents,allelectricpowersupplylinesmust
be disconnected from the appliance running, before the eventual removal of the
hermetic covers, etc.
Whenever it is absolutely necessary to have electric power supply for the unit
during maintenance, a constantly active leak detector must be positioned in the
most critical point in order to signal a potentially dangerous situation.
• Particularattentionmustbepaidtothefollowingtoguaranteethat,inthecaseof
intervention on electric components, the housing is not altered in a way to affect
the level of protection.
This includes damage to cables, excessive number of connections, terminals not
manufacturedincompliancewithoriginalspecications,damagetothegaskets,
incorrect installation of the closing devices, etc.
• Makesurethattheappliancesaremountedsecurely.
• Makesurethatthegasketsorsealingmaterialshavenotdeterioratedtothepoint
thattheycannotbeusedtopreventtheentryofinammableatmospheres.The
sparecomponentsmustbecompliantwithmanufacturerspecications.
Theuseofsilicone-basedsealantscaninhibittheefcacyofsometypesof
leak detection equipment.
Intrinsically safe components do not have to be isolated before working on
them.
