SPECIALIST'S MANUAL

• 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.
• 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.
• Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector
prior to and during work, to ensure the technician is aware of
potentially toxic or flammable
atmospheres. Ensure that the leak detection equipment being used
