2-7. Checks to the refrigerating 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 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.
- 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 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 properly protected against being so
corroded.
2-8. Checks to electrical devices
• Repair and maintenance to electrical
components shall include initial safety checks
and component inspection procedures.
• Initial safety checks shall include but not limit
to:-
- That capacitors are discharged: this
shall be done in a safe manner to avoid
possibility of sparking.
- That there no live electrical components
and wiring are exposed while charging,
recovering or purging the system.
- That there is continuity of earth bonding.
• At all times the manufacturer’s maintenance
and service guidelines shall be followed.
• If in doubt consult the manufacturer’s
technical department for assistance.
• 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.
• The owner of the equipment must be
informed or reported so all parties are
advised thereinafter.
