The following checks should 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
should be checked for the presence of refrigerant.
• Marking to the equipment continues to be visible and legible.
Markings and signs that are illegible should 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 should include initial
safety checks and component inspection procedures. If a fault exists that
could compromise safety, then no electrical supply should 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 should be used. This should be reported to the owner
of the equipment so all parties are advised. Initial safety checks should
include:
• That capacitors are discharged: this should 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.
2. Repairs to sealed components
• During repairs to sealed components, all electrical supplies should 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
