• 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 purification 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 specifications, 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 inflammable atmospheres. The
spare components must be compliant with manufacturer specifications.
The use of silicone-based sealants can inhibit the efficacy of some types of
leak detection equipment.
Intrinsically safe components do not have to be isolated before working on
them.
