IMPORTANT SAFETY INSTRUCTION
WARNING
For using R32 refrigerant
shall be available to hand. Have a dry powder
or CO2 re extinguisher adjacent to the
charging area.
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 ammable refrigerant shall
use any sources of ignition in such a manner
that it may lead to the risk of re or explosion.
All possible ignition sources, including
cigarette smoking, should be kept suciently
far away from the site of installation, repairing,
removing and disposal, during which
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 that there are
no 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 preferably expel it
externally into the atmosphere.
8. Checks to the refrigeration equipment:
Where electrical components are being
changed, they shall be t for the purpose
and to the correct specication. 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 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
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
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 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
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.
SEALED ELECTRICAL COMPONENTS
SHALL BE REPLACED
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.
2. Particular attention shall be paid to the
following to ensure that by working on
electrical components, the casing is not
altered in such a way that the level of
protection is aected. This shall include
