8. Checks to the refrigeration equipment:
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. The following checks
shall be applied to installations using flammable refrigerants:
-- the charge size 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;
-- 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; that no live electrical
components and wiring are exposed while charging, recovering or purging the
system; that there is continuity of earth bonding.
10. Sealed electrical components shall be replaced.
