5. RISK ANALYSIS AND HAZARDOUS SITUATIONS ACCORDING TO PED DIRECTIVE
N° Event Effect Risk
Actions to Eliminate
the Risk Information to minimise
the occurrence of a risk
8A
Unit exposed to
extremely corro-
sive materials.
Modi fi cation of the
mechanical and
chemical properties
of certain materials
with a risk or corrosion
rupture, pipe bursting,
leaks and cracks. Partial or complete de-
struction of the circuit,
liquid/gas/ metal parts
could be thrown out of
the unit
Protect the units against
these types of products Indications in the technical
IOM supplied
9A
Unit exposed
to explosive
materials.
Risk of explosion or
pipe bursting.
Partial or complete de-
struction of the circuit,
liquid/gas/ metal parts
could be thrown out of
the unit
Protect the units against
these types of products Indications in the technical
IOM supplied
10A
Inappropriate Heat
Transfer Fluid Corrosion, excessive
heat
Partial or complete de-
struction of the circuit.
Leaks
Usual fl uids are Water or
Water with Glycol.
Indications in the technical
IOM supplied
11A
Inappropriate
refrigerant
fl uid in
the circuit
Corrosion, excessive
heat, combustion or
explosion
Partial or complete de-
struction of the circuit,
liquid/gas/ metal parts
could be thrown out of
the unit
Only use the fl uid
speci fi ed on the unit’s
nameplate.
Indications of t he refrig-
erant
fl uid on the unit
nameplate
12A
Inappropriate oil in
the compressor Corrosion, excessive
heat,
Partial or complete de-
struction of the circuit.
Leaks
Authorized oils: Refer
to the compressor
nameplate or the
documentation.
Indication on the compres-
sor nameplate or the man-
ufacturer documentation.
13A
Working on a part
under pressure
Risk of explosion or
part bursting away
from the machine. Liquid/gas/metal parts
could be thrown out of
the unit
Isolate the section of the
circuit to be worked on
and recover the refrig-
erant before any work.
Always wear protection
goggles and gloves.
Indications in the technical
IOM supplied
14A
Brazing or
un-brazing parts
from the circuit
Strains, cracks, pipe
bursting
Partial or complete de-
struction of the circuit,
liquid/gas/ metal parts
could be thrown out of
the unit
Parts to be brazed
using best engineering
practices. Use brazing
materials approved by
LENNOX. Ensure the
circuit is leak free before
re
fi lling with refrigerant.
Indications in the technical
IOM supplied
15A
Unit exposed
to induct ive
interferences
Corrosions, cracks leaks
Ensure the unit is
earthed properly Indications in the technical
IOM supplied
16A
Unit exposed to
internal or external
vibrations
Strains, cracks,
explosions
Partial or complete de-
struction of the circuit,
liquid/gas/ metal parts
could be thrown out of
the unit
Inspect the unit regularly
Indications in the technical
IOM supplied
6. END OF THE MACHINE LIFE
At the end of the useful life of the units, please take into account the correct segregation of the waste generated. No Hazardous like:
Painted metallic parts, plastic elements, copper pipes, batteries, exchangers, liquid receivers, water pumps, fans.. And Hazardous
Materials such as batteries, electrical and electronic elements, compressors, dehydrating
fi lters, valves or refrigerant gas, etc. to be
managed with an authorized dealer.
