presence of refrigerant;
- the marking of the equipment continues to be visible and legible. Marks and symbols that
are illegible must be corrected;
- the refrigeration pipe or components are installed in a position where they are not likely
to be exposed to a substance that may corrode elements containing refrigerants, unless
these elements are constructed with materials that are inherently resistant to corrosion or
that are adequately protected against corrosion.
- Checking of electrical devices
Repair and maintenance operations on electrical components must include initial safety
checks and component inspection procedures. In the presence of a fault that may
compromise safety, no power supply shall be connected to the circuit until the fault has
been satisfactorily addressed. If the defect cannot be corrected immediately but it is
necessary to continue the operations, an appropriate temporary solution must be used.
This should be communicated to the owner of the equipment so that all parties involved
are aware of it.
Initial security checks should include:
- checking that the capacitors are discharged: this must be done in a safe way to avoid
any possibility of sparks;
- Verification that no live electrical components or wiring are exposed during charging,
recovery or purging of the system;
- verification that there is continuity of the equipotential bonding to earth.
- Repairs of hermetic components
During repairs of hermetic components, all power supplies must be disconnected from the
equipment undergoing operations before any removal of hermetic covers, etc. If it is
absolutely necessary to supply the equipment with electricity during service operations, a
continuously operating leak detection device must be located at the most critical point to
give warning in case of a potentially dangerous situation.
Particular attention should be paid to the following to ensure that when working on
electrical components, the enclosure is not altered in a way that alters the level of
protection. This should include damage to cables, excessive number of connections,
terminals that do not meet the original specification, damage to seals, incorrect
adjustment of cable entries, etc.
Make sure that the unit is mounted safely.
Ensure that the joints or sealing materials have not degraded to the point of no longer
preventing the penetration of flammable atmospheres. Spare parts must comply with the
manufacturer's specifications,
NOTE: The use of a silicone sealant can inhibit the effectiveness of certain types of leak
detection equipment. Intrinsically safe components do not have to be isolated before
undergoing a procedure
- Repair of intrinsically safe components
Do not apply inductive loads or permanent capacities to the circuit without ensuring that it
will not exceed the permissible voltage and current allowed for the equipment used.
