The product label should never be removed from the unit.
1.10 Unit identication
Each unit has a rating plate that provides key information regarding the machine.
The rating plate may differ from the one shown below as the example is for a standard unit without accessories.
For all electrical information not provided on the label, refer to the wiring diagram.
A facsimile of the label is shown below:
Rev. A 11-2020

For further information regarding the characteristics of the refrigerant and oil used, refer to the safety data sheets
available from the refrigerant and oil manufacturers.
2.1 Warning re potentially hazardous toxic substances
2.1.2 Identication of the Type of Oil Used.
2. SAFETY
The lubricant used is polyester oil. Please refer to the information provided on the compressor data plate.
ENVIRONMENTAL PROTECTION : Read the ecological information and the following instructions carefully.
2.1.3 Persistence and degradation
2.1.4 Effects of discharges
2.1.5 Exposure controls and personal protection
2.1.6 Professional exposure limits
2.2 Refrigerant handling
The refrigerants used decompose in the lower atmosphere (troposphere) relatively quickly. The decomposed products are highly dispersible
and therefore have a very low concentration. They do not inuence the photochemical smog which is not among the VOC volatile organic
compounds (as stipulated in the guidelines to the UNECE). The constituent refrigerants of R410A, do not damage the ozone layer. These
substances are regulated under the Montreal Protocol (revised 1992) and regulations EC no. 2037/200 of 29 June 2000.
Discharges into the atmosphere of this product does not cause a long-term contamination.
Wear protective clothing and gloves, protect your eyes and face

2.3 Prevent inhalation of high vapor concentration
2.4 Procedures to be adopted in the event of accidental release of refrigerant
2.5 Main Toxicological Information Regarding the Type of refrigerant used
2.5.1 Inhalation
A high atmospheric concentration can cause anaesthetic effects with possible loss of consciousness. Prolonged exposure may lead to irre-
gular heartbeat and cause sudden death. Higher concentrations may cause asphyxia due to the reduced oxygen content in the atmosphere.
2.5.2 Contact with skin
Splashes of nebulous liquid can produce frostbite. Probably not hazardous if absorbed trough the skin. Repeated or prolonged contact may
remove the skin’s natural oils, with consequent dryness, cracking and dermatitis.
2.5.3 Contact with eyes
Splashes of liquid may cause frostbite.
2.5.4 Ingestion
While highly improbable, may produce frostbite.
Atmospheric concentrations of refrigerant must be minimized and kept to a level that is below the occupational exposure limit. Vapor is
heavier than air and can form dangerous concentrations near the ground where the ventilation rate is lower. Always ensure adequate venti-
lation. Avoid contact with open ames and hot surfaces as this can cause toxic and irritating decomposition products to form. Avoid contact
between liquid refrigerant and the eyes or skin.
Ensure suitable personal protection (especially respiratory protection) during cleaning operations.
If deemed safe, isolate the source of the leak. If the leakage is small and if adequate ventilation is provided, allow the refrigerant to evapo-
rate. If the loss is substantial ensure that measures are taken to adequately ventilate the area.
Contain spilled material with sand, earth or other suitable absorbent material.
Do not allow the refrigerant to enter drains, sewers or basements, as pockets of vapor can form.
2.6 First Aid Measures
2.6.1 Inhalation
2.6.2 Contact with skin
Move the person away from the source of exposure, keep him/her warm and let him/her rest. Seek medical assistance.
In case of contact with skin, wash immediately with lukewarm water. Thaw tissue using water. Remove contaminated clothing. Clothing may
stick to the skin in case of frostbite. If irritation, swelling or blisters appear, seek medical assistance.
Adhere scrupulously to the warnings and rst aid procedures indicated below.
2.6.3 Contact with eyes
Rinse immediately using an eyewash or clean water, keeping eyelids open, for at least ten minutes. Seek medical assistance.
2.6.4 Ingestion
Do not induce vomiting. If the injured person is conscious, rinse his/her mouth with water and make him/her drink 200-300ml of water. Seek
immediate medical assistance.
2.6.5 Further medical treatment
Treat symptoms and carry out support therapy as indicated. Do not administer adrenaline or similar sympathomimetic drugs following
exposure, due to the risk of cardiac arrhythmia.
