• Marking 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, and 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 there no live electrical components and wiring are exposed
while charging, recovering or purging the system;
• That there is continuity of earth bonding.
7. Repairs to sealed components
1) During repairs to sealed components, all electrical supplies shall be
disconnected from the equipment being worked upon prior to any
removal of sealed covers, etc. If it is absolutely necessary to have an
electrical supply to equipment during servicing, then a permanently
operating form of leak detection shall be located at the most critical
point to warn of a potentially hazardous situation.
