SAVE THESE INSTRUCTIONS!
6. No ignition sources: No person carrying out work in relation to a refrigeration system which involves
exposing any pipe work that contains or has contained fl ammable refrigerant shall use any sources
of ignition in such a manner that it may lead to risk of fi re or explosion. All possible ignition sources
including cigarette smoking, should be kept suffi ciently far away from the site of installation, repairing,
removing and disposal during which fl ammable refrigerant can possibly be released to the surrounding
space. Prior to work taking place, the area around the equipment is to be surveyed to make sure there
are no fl ammable hazards or ignition risks. No smoking signs shall be displayed.
7. Ventilated area: Ensure that the area is in the open or that it is adequately ventilated before breaking
into the system or conducting any hot work. A degree of ventilation shall continue during the period
that the work is carried out. The ventilation should safely disperse any released refrigerant and
preferable expel it externally into the atmosphere.
8. Checks to the refrigeration equipment: Where electrical components are being changed, they shall
be fi t for the purpose and to the correct specifi cation. 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 fl ammable 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 become illegible
must 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 suitable protected
against being 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.
