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;
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.
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.
Repairs to sealed 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.
