SAFETY AND POLLUTION
General considerations
The machine has been designed to reduce the risks to persons and to the environment in which it is installed, to the
minimum. To eliminate residue hazards, it is therefore advisable to become as familiar as possible with the machi-
ne in order to avoid accidents that could cause injuries to persons and/or damage to property.
a. Access to the unit
Only qualified persons who are familiar with this type of machine and who are equipped with the necessary safety
protections (footwear, gloves, helmet, etc.) may be allowed to access the machine. Moreover, in order to operate,
these persons must have been authorized by the owner of the machine and be recognized by the Manufacturer
itself.
b. Elements of risk
The machine has been designed and built so as not to create any condition of risk. However, residue hazards are
impossible to eliminate during the planning phase and are therefore listed in the following table along wqith the
instructions on how to neutralize them.
Part in question
Residue hazard
Mode
Precautions
Compressor and delivery pipe
Burns
Contact with the pipes and/or
the compressor
Avoid contact by wearing pro-
tective gloves
Turn off the machine, check
the high pressure switch and
safety valve, the fans and con-
denser
Bank and delivery pipes
Bursting
Excessive pressure
Pipes in general
Ice burns
Leaking coolant
Do not exercise tension on the
pipes
Electric cables, metal parts
Electrocution, serious burns
Defective cable insulation, live
metal parts
Adequate electrical protection
(correctly ground the unit)
Heat exchange banks
Cuts
Contact
Wear protective gloves
Do not push the hands or
objects through the fan grille
Contact with the skin
Cuts
Electric fans
c. Pollution
The machine contains R22 or R407C coolant and lubricating oil. Thus, if the appliance is scrapped, these fluids must
be recovered and disposed of in accordance with the laws in force in the country where the machine is installed.
The machine must not be abandoned when scrapped.
General recommendations about the coolant used
The cooling circuit of the machine is filled with R22 or R407C cooling gas. If it escapes, this gas will damage the
atmospheric ozone. When no longer required for use, the machine must therefore be consigned to an authorized
disposal center. Indications about the characteristics of this gas and how to act if it should accidentally escape are
given below.
Danger indication
• Low toxicity.
• Inhalation of the gas for long periods can have anaesthetic effects.
• Prolonged exposure can alter the heart rate and cause death.
• The product can cause ice burns on the eyes and/or skin.
