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
Thermal heat
exchangers.
Fan and fan grilles.
Internal component:
compressors and
discharge pipes
Internal component:
electric cables and
metallic parts
External to unit:
unit enclosure
Low pressure safety
valve.
High pressure safety
valve.
Entire unit
Entire unit
POTENTIAL
RISK
Small stab wounds.
Cuts, eye damage,
broken bones.
Burns.
Electrocution,
severe burns.
Poisoning,
severe burns.
Poisoning,
severe burns.
Poisoning,
severe burns,
hearing loss.
External fire
Explosion, injuries,
burns, poisoning,
folgoramento for natural
disasters or earthquake.
METHOD OF INJURY
Contact
Insertion of sharp objects
through the grid while the
fans are operating.
Contact
Defect in the supply ca-
ble insulation, live metal-
lic parts.
Fire due to short circuit
or overheating of the
supply cable external to
unit.
High evaporating pres-
sure causing a refgrig-
erant discharge during
maintenance.
Activation of the high
pressure safety valve
with the refrigerant circuit
open.
Fire due to natural dis-
asters or combustions of
elements nearby unit
Breakages, failures due
to natural disasters or
earthquake
5
PRECAUTIONS
Avoid any contact,
use protective gloves.
Never put objects through the protection grilles.
Avoid any contact, use protective gloves.
Adequate protection of power cables, ensure
correct earthing of all metal parts.
Size cables and mains protection system in ac-
cordance with iee regulations.
Carefully check the evaporating pressure dur-
ing the maintenance operations. Use all personal
protective equipment required by the law. PPE
must also protect against gas leaks from the
safety valve. The outlet of these valves is di-
rected to avoid causing damage to persons or
goods.
If possible, do not open the refrigerant circuit
valve; carefuly check the condensing pressure;
use all the personal protective equipment re-
quired by law. PPE must also protect against gas
leaks from the safety valve. The outlet of these
valves is directed to avoid causing damage to
persons or goods.
Provide the necessary fire-fighting equipment
Plan the necessary precautions both electrical
(suitable differential magneto and electrical pro-
tection of the supply lines; greatest care during the
connections of the metal parts), and mechanical
(special anchors or seismic vibrations to prevent
breakages or accidental falls ).
