8. Checks to the refrigeration equipment
Where electrical components are being changed, they shall
be fit for the purpose and to the correct specification. The
manufacturer’s maintenance and service guidelines shall be
followed at all times. If in doubt consult the manufacturer’s
technical department for assistance. The following checks shall
be applied to installations using flammable refrigerants:
• That the charge size is in accordance with the room size within
which the refrigerant containing parts are installed.
• That the ventilation machinery and outlets are operating
adequately and are not obstructed.
• That if an indirect refrigerating circuit is being used,
the secondary circuit shall be checked for the presence of
refrigerant. That markings on the equipment continue 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.
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.
