combustible coolant exposed, use
all sources of ignition in such a
way that it cannot lead to a risk of
fire. All possible sources of
ignition, including cigarettes, must
be kept at a sufficient distance
from the place of installation,
repair, removal and drainage,
during which potentially
flammable refrigerant can be
released into the surrounding
space. Before the work is carried
out, the area around the
equipment must be checked to
ensure that there is no risk of
ignition. Non smoking signs must
placed also.
7) Area Ventilation
Ensure that servicing area is
outside or that it is sufficiently
ventilated before the system is
opened or when there is hot
welding work. There must be
ventilation during the period that
the work is being carried out. The
ventilation must safely disperse
any refrigerant released and
preferably emit it externally to the
atmosphere.
8) Cooling equipment checks
If electrical components are
changed, they must be fully
suitable and compatible with
original installed parts and must
have the correct specification.
The manufacturer's maintenance
and service guidelines must
always be followed. If in doubt,
consult the manufacturer's
technical service for assistance.
The following checks must be
carried out on installations that
use flammable refrigerants:
The load size must be in
accordance with the load which
the refrigerant-containing
components are installed;
The ventilation equipment and
outlets work adequately and are
not impeded;
If an indirect cooling circuit is
used, the secondary circuit must
be checked for the presence of
cooling refrigerant; The marking
on the equipment is visible and
legible. Marks and signs that are
unreadable must become.
corrected;
Cooling pipes or components
must be installed in a place where
it is unlikely that they will be
exposed to a substance that can
affect coolant-containing
components, unless the
components are made of
materials that are inherently
corrosion-resistant or suitably
protected against be corroded.
7. Checking of electrical
appliances
1) During repairs or welding
pipe parts, all electrical devices
must be disconnected from power
supply. If it is absolutely
necessary to have an electrical
supply during maintenance work,
there must be a permanently
functioning form of leak detection
at the most critical point to warn of
a potentially dangerous situation.

In particular, pay attention to
