Information on Servicing
Where electrical components are being changed, they shall be fit for the purpose
and to the correct specification. At all times the manufacturer’s maintenance and
service guidelines shall be followed. If in doubt, consult the manufacturer’s
technical department for assistance.
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:
During repairs to sealed components, all electrical supplies shall be disconnected

If it is absolutely necessary to have an electrical supply to equipment during servicing,
manner to avoid
possibility of sparking;
le charging,
recovering or purging the system;
The following checks shall be applied to installations using FLAMMABLE
REFRIGERANTS:
ich the refrigerant
containing parts are installed;
y and are not
obstructed;
dary circuit shall be
checked for the presence of refrigerant;
Markings and
signs that are illegible shall be corrected;
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.
