The operator must only intervene on the unit controls. He or she must not open any panels except for the one which gives
access to the control module.
The installer must only intervene on the connections between the plant and the machine. He or she must not open any
machine panels nor carry out any commands.
The following precautions should be made when approaching or working on the unit:
• do not wear jewellery, baggy clothes or any other accessory which can get caught up.
• Use appropriate protection (gloves, glasses etc.) when using an open flame (welding) or compressed air.
• If the unit is located in a closed environment, wear hearing protection.
• before disconnecting, removing tubes, filters, joints or other line parts intercept the connection tubes, empty them until
the pressure reaches that of the atmosphere.
• do not use your hands to check for possible pressure losses.
• always use tools which are in good condition; make sure the instructions have been fully understood before using them.
• make sure that any tools, electrical cables or other loose objects have been removed before closing the unit and starting
it up again.
Precautions against risks due to the refrigerant
Precautions against residual risks
Prevention from risks due to the command system
• make sure the instructions for use have been understood before carrying out any work on the control panel
• always keep the instruction manual close at hand when working on the control panel
• start up the unit only after having certified that it is correctly connected to the plant
• inform the technician promptly of any alarms which appear on the unit
• do not reset the alarms to manual restart without having first identified the cause and removed it
Prevention against residual mechanical risks
• install the unit in accordance with the provisions of the following manual
• carry out all the maintenance operations provided for by this manual regularly
Safety data R410a
Toxicity
Not important
Risks for skin touching
Splashes or sprinkles can cause chill burns. The risk of absorptions through the skin is not relevant.
Those refrigerants could take some lightly irritating effects and in liquid stage they have a strong skinning effect. In this case it
is necessary to rinse with fresh water the contaminated parts of the skin
The refrigerant in liquid stage in contact with wet clothes causes freezing and adherence to the skin. In this case it is neces-
sary to take off the contaminated clothes to avoid freezing. Contact a doctor in case of irritation of the contaminated parts.
Risks for contact with the
eyes Vapors don’t take any effect. Splashes or sprinklers can cause chill burns. In those cases it is necessary to rinse eyes with
water or with solution for ocular washings for 10 minutes. The intervention of a doctor is needed.
Risks for ingestion
Should it happen, it causes chill burns. It does not cause vomiting. The person must be kept awake. It is needed to rinse the
mouth with fresh water and to drink almost 0,25 liters. The intervention of a doctor is useful.
Risks for inhalation
High concentration of vapours in air can lead to anaesthetic effects up to a loss of conscience. Long exposures could give
rise to cardiac arrhythmia and sometimes even to death.
High concentrations can create a reduction of oxygen in air, with consequent possibility of suffocation. Should it happen the
person must be taken to the open air and let him to take a rest.
Administer oxygen if needed. In case the breathing has interrupted or become irregular, it is necessary to apply the artificial
breathing. In case of cardiac arrest a heart massage must be applied. Contact a doctor immediately.
Conditions to avoid
Use in presence of exposed flames, and of high levels of humidity.
Dangerous reactions
Possibility of violent reactions with the sodium, the potassium, the barium and with other alkaline substances, incompatible
materials and all the alloys containing more than 2% of magnesium.
Protection wearing - Behav-
ior in case of losses or
leaks
Wear protection apparel and self respirators. Insulate the source of the loss, if this operation can be done in safety condi-
tions. Small quantitative of refrigerant escaped at liquid state can be allowed to evaporate only if the room is well ventilated.
In case of great losses ventilate the room immediately. Plug
the loss with sand, soil or other absorbent material; avoid that
the liquid refrigerant can enter in water-drainages or losing pools.
Disassembly
The best procedure is the recovery and the recycle. If this is not possible the refrigerant must be conferred to an accredited
system for its destruction in order to neutralize acid and toxic by-products.
