Las comprobaciones previas de seguridad deben incluir:
• Capacitors are discharged: this must be done in a safe manner to avoid the risk of sparks;
• Make sure that no electrical components or cables are exposed during refrigerant charging, recovery,
or system purging;
• Make sure there is continuity in the ground connection.
10. REPAIRS TO SEALED COMPONENTS
10.1 During repair of sealed components, all electrical supplies should be disconnected from the equipment
being worked on before removing sealed covers, etc. If it is absolutely necessary for the equipment to be
powered during maintenance, a leak detector should be permanently placed at the most critical point to
warn of a potentially dangerous situation.
10.2 Special attention should be paid to the following to ensure that working on electrical components
does not affect the enclosure to the point of diminishing protection. This includes damage to cables,
excessive number of connections, terminals out of specications, damage to gaskets, incorrect installation
of bushings, etc.
• Make sure the unit is securely mounted.
• Make sure gaskets or sealing material are not worn to the point that they do not perform their
function of preventing the entry of ammable atmospheres. Replacement parts must always meet the
manufacturer's specications.
NOTA: The use of silicone as a seal can hinder the effectiveness of some leak detection equipment. Safe
components usually do not have to be isolated before working on them.
11. REPAIR OF INTRINSICALLY SAFE COMPONENTS
Do not apply inductive or capacitance loads to the circuit without ensuring that this will not exceed the
voltage or current allowable for the equipment in use. Intrinsically safe components are the only ones that
can be worked with in the presence of a ammable atmosphere.
The tester must have the correct range. Replacement of components should only be done with parts specied
by the manufacturer. If you use other components you run the risk of refrigerant re in the atmosphere due
to a leak..
12. CABLES
On cables, check: wear, corrosion, excessive pressure, vibration, sharp edges or any other damage they may
have. The effects of time or continued vibration from sources such as compressors or fans must also be
taken into account.
13. DETECTION OF FLAMMABLE REFRIGERANTS
Under no circumstances should ignition sources be used as refrigerant leak detectors. Halide lamps (or any
other detector that uses an open ame) should not be used.
14. LEAK DETECTION METHODS
The following leak detection methods are accepted for systems containing ammable refrigerants. Electronic
leak detectors will be used to detect ammable refrigerants, but the sensitivity may not be adequate or
they may require recalibration. (Detection equipment must be calibrated in an area without refrigerant.)
Make sure the detector is not a potential ignition source and is compatible with the coolant used. The leak
detector must be set to a percentage of the LFL of the refrigerant and calibrated for the refrigerant used
and the appropriate percentage of the gas must be conrmed (25% maximum). Fluid leak detection is
compatible for use with most refrigerants, but chlorine-containing detergents should be avoided as they can
react with the refrigerant and corrode copper piping.
If a leak is suspected, all ignition sources should be eliminated or turned off. If a refrigerant leak is found
that requires welding, all refrigerant must be purged from the system or isolated (by closing valves) at a
