IMPORTANT SAFETY INSTRUCTION
(Continued)
8. Checks to the refrigeration equipment:
Where electrical components are being
changed, they shall be t for the purpose
and to the correct specication. At all times
the manufacturer’s maintenance and service
guidelines shall be followed. If in doubt consult
the manufacturer’s technical department for
assistance.
The following checks shall be applied to
installations using ammable refrigerants:
• The charge size is in accordance with the
room size within which the refrigerant
containing parts are installed.
• The ventilation machinery and outlets are
operating adequately and are not obstructed.
• If an indirect refrigerating circuit is being
used, the secondary circuit shall be checked
for the presence of refrigerant.
• Marking to the equipment continues to be
visible and legible. Markings and signs that
are illegible should be corrected.
• Refrigeration pipe or components are
installed in a position where they are unlikely
to be exposed to any substance which may
corrode refrigerant containing components,
unless the components are constructed of
materials which are inherently resistant to
being corroded or are suitably protected
against being so corroded.
9. Checks to electrical devices:
• Repair and maintenance to electrical
components should include initial safety
checks and component inspection
procedures. If a fault exists that could
compromise safety, then no electrical supply
shall be connected to the circuit until it is
satisfactorily dealt with. If the fault cannot be
corrected immediately but it is necessary to
continue operation, an adequate temporary
solution should be used. This should be
reported to the owner of the equipment, so
all parties are advised.
• Initial safety checks should include:
• That capacitors are discharged: this
shall be done in a safe manner to avoid
possibility of sparking.
• That there no live electrical components
and wiring are exposed while charging,
recovering or purging the system.
• That there is continuity of earth bonding.
SEALED ELECTRICAL COMPONENTS
SHALL BE REPLACED
INTRINSICALLY SAFE COMPONENTS
MUST BE REPLACED
CABLING
• Check that cabling will not be subject to wear,
corrosion, excessive pressure, vibration, sharp
edges or any other adverse environmental
eects. The check shall also take into account
the eects of aging or continual vibration from
sources such as compressors or fans.
DETECTION OF FLAMMABLE
REFRIGERANTS
•
Under no circumstances, should potential sources
of ignition be used in the searching for or detection
of refrigerant leaks. A halide torch (or any other
detector using a naked ame) should not be used.
• The following leak detection methods are
deemed acceptable for systems containing
ammable refrigerants. Electronic leak detectors
shall be used to detect ammable refrigerants,
but the sensitivity may not be adequate, or
may need re-calibration. (Detection equipment
should be calibrated in a refrigerant-free area.)
Ensure that the detector is not a potential source
of ignition and is suitable for the refrigerant
used. Leak detection equipment should be set
at a percentage of the LFL of the refrigerant and
shall be calibrated to the refrigerant employed
and the appropriate percentage of gas (25 %
maximum) is conrmed.
• Leak detection uids are suitable for use with
most refrigerants but the use of detergents
containing chlorine shall be avoided as the
chlorine may react with the refrigerant and
corrode the copper pipework.
