• Installation of pipe work shall be kept to a minimum and pipe work shall be protected from physical damage and shall
not be installed in an unventilated space.
• Reusable mechanical connectors and
fl
are joints shall be accessible for maintenance purposes.
WARNING
Prior to installation, ensure risk of ignition is minimised and avoid working in con
fi
ned space.
Ensure adequate ventilation is available by opening windows or doors.
●
When
fl
ared joints are reused indoors, the
fl
are part shall be re-fabricated.
●
A void installation of the air conditioner in a place where there is danger of exposure to continuously
operating open
fl
ames (for example an operating electric heaters).
●
Any person who is involved with working on or breaking into a refrigerant circuit should hold a current
valid certi
fi
cate from an industry-accredited assessment authority, which authorises their competence to
handle refrigerants safely in accordance with an industry recognised assessment speci
fi
cation.
●
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
fl
ammable atmospheres. Ensure that the leak detection equipment
being used is suitable for use with
fl
ammable refrigerants, i.e. nonsparking, adequately sealed or
intrinsically safe.
●
Presence of
fi
re extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate
fi
re
extinguishing equipment shall be available to hand. Have a dry powder or CO
2
fi
re extinguisher adjacent
to the charging area.
●
No ignition sources
All possible ignition sources, including cigarette smoking, should be kept suf
fi
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. “No Smoking” signs shall be displayed.
●
The following checks shall be applied to installations:
– 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.
●
Initial safety checks shall include:
– that capacitors are discharged, this shall be done in a safe manner to avoid possibility of sparking
– there shall be no live electrical components and wiring are exposed while charging, recovering or
purging the system;
