Important Safety Information
READ AND FOLLOW ALL SAFETY INSTRUCTIONS
8) Checks to the refrigeration equipment: Where electrical components are being changed, they shall be
fi t for the purpose and to the correct specifi cation. 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 fl ammable refrigerants:
• The actual refrigerant 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.
• Markings on the equipment continues to be visible and legible. Markings and signs that become
illegible must 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 suitable protected
against being corroded.
9) Checks to electrical devices: Repair and maintenance to electrical components shall 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 shall be
used. This shall be reported to the owner of the equipment so all parties are advised. Initial safety checks
shall include:
• That capacitors are discharged. This shall be done in a safe manner to avoid possibility of sparking.
• That no live electrical components and wiring are exposed while charging, recovering or purging
the system.
• That there is continuity of earth bonding.
7. Repairs to sealed components
1) During repairs to sealed components, all electrical supplies shall be disconnected from the equipment
being worked upon prior to any removal of sealed covers, etc. If it is absolutely necessary to have an
electrical supply to equipment during servicing then a permanently operating form of leak detection shall
be located at the most critical point to warn of a potentially hazardous situation.
2) Particular attention shall be paid to the following to ensure that by working on electrical components, the
casing is not altered in such a way that the level of protection is affected. This shall include:
• Damage to cables, excessive number of connections, terminals not made to original specifi cation,
damage to seals, incorrect fi tting of glands, etc.
• Ensure the apparatus is mounted securely.
• Ensure that seals or sealing materials have not degraded such that they no longer serve the purpose
of preventing the ingress of fl ammable atmospheres. Replacement parts shall be in accordance with
the manufacturer's specifi cations.
Note: The use of silicon sealant may inhibit the effectiveness of some types of leak detection equipment.
Intrinsically safe components do not have to be isolated prior to working on them.
