Area ventilation
• Prior to penetrating the unit in any way to perform any required service, ensure that the area is open and
adequately ventilated. Proper ventilation, to allow for safe dispersion of any refrigerant which may be
inadvertently released to the atmosphere, should be maintained while service is being performed on the unit.
Refrigeration equipment check
• The manufacturer's service and maintenance guidelines must be followed at all times. When replacing any
electrical components, be sure to use only components which are of the same type and rating and which are
recommended/approved by the manufacturer. If in doubt, consult the manufacturer's technical department
for assistance.
• The following checks shall be applied to installations using flammable refrigerants:
- 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 shall
be corrected;
- refrigerating pipe or components are installed in a position where they are unlikely to de 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.
Electrical component check
• 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.
Repair of insulated components
• 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.
• 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 specification, damage to seals,
incorrect fitting of glands, etc.
• Ensure that the apparatus is mounted securely.
• Ensure that seals or sealing materials have not degraded to the point that they no longer serve the purpose
of preventing the ingress of flammable atmospheres. Replacement parts shall be in accordance with the
manufacturer's specifications.
