1.6 Potential Risks
Whilst the unit has been designed to minimize any risk posed to the safety of people who will interact with it, it has not been technically
possible to eliminate completely the causes of risk. It is therefore necessary to refer to the requirements and symbolism below:
LOCATION OF
RISK
POTENTIAL RISK
METHOD OF INJURY
PRECAUTIONS
Thermal heat
exchangers.
Small stab wounds.
Contact
Avoid any contact,
use protective gloves.
Fan and fan grilles.
Cuts, eye damage,
broken bones.
Insertion of sharp objects
through the grid while the fans
are operating.
Never put objects through the pro-
tection grilles.
Internal component:
compressors and
discharge pipes
Burns.
Contact
Avoid any contact, use protective
gloves.
Internal component:
electric cables and
metallic parts
Electrocution,
severe burns.
Defect in the supply cable in-
sulation, live metallic parts.
Adequate protection of power ca-
bles, ensure correct earthing of all
metal parts.
External to unit:
unit enclosure
Poisoning,
severe burns.
Fire due to short circuit or
overheating of the supply ca-
ble external to unit.
Size cables and mains protection
system in accordance with iee regu-
lations.
Low pressure safety
valve.
Poisoning,
severe burns.
High evaporating pressure
causing a refgrigerant dis-
charge during maintenance.
Carefully check the evaporating
pressure during the maintenance
operations.
High pressure safety
valve.
Poisoning,
severe burns,
hearing loss.
Activation of the high pressure
safety valve with the refriger-
ant circuit open.
If possible, do not open the refrig-

Breakages, failures due to natu-
ral disasters or earthquake
Plan the necessary precautions both
electrical (suitable differential ma-
gneto and electrical protection of the
supply lines; greatest care during the
connections of the metal parts), and
mechanical (special anchors or sei-
smic vibrations to prevent breakages
or accidental falls ).
