–
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.
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.
