e instruction book is an integral and essential part of the product and must be consigned to the new user also in the case of transfer or succession of ownership.

It must be stored with care and consulted carefully, as all of the warnings provide important safety indications for installation, use and maintenance stages.

is instructions manual provides technical information for installing Immergas appliance. As for the other issues related to appliance installation (e.g. safety

in the work site, environment protection, injury prevention), it is necessary to comply with the provisions specied in the regulations in force and principles

of good practice.

In compliance with legislation in force, the systems must be designed by qualied professionals, within the dimensional limits established by the Law. Installation

and maintenance must be performed in compliance with the regulations in force, according to the manufacturer's instructions and by professionally qualied

sta, intending sta with specic technical skills in the plant sector, as envisioned by the Law.

Improper installation or assembly of the Immergas appliance and/or components, accessories, kit and devices can cause unexpected problems to people, animals

maintaining, or dismantling the unit in order to eliminate uncertainty and reduce risk.

In these instructions symbols have been used (described in the following paragraphs) to draw the attention of operators and users to the

operations that have a higher risk and which must be performed safely.

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:

BANNED

A black symbol inside a red circle with a red diagonal indicates an action that should not be performed.

WARNING

A black graphic symbol added to a yellow triangle with black edges indicates danger.

ACTION REQUIRED

A white symbol inserted in a blue circle indicates an action that must be done to avoid a risk.

Thegraphicsymbol“warning”isqualiedwithadditionalsafetyinformation(textorothersymbols).

Safety symbols combined in accordance with ISO 3864-2:

1.7 General Description of Symbols Used

Safety symbols combined in accordance with ISO 3864-2:

GENERAL RISK

RECOVER OR RECYCLE MATERIAL

1.8 Safety symbols used

1.9 Limitations and prohibited use

The machine is designed and built exclusively for the uses described in “Limitations of use” of the technical manual.

Any other use is prohibited because it may pose a potential risk to the health of operators and users.

The unit is not suitable for operations in environments:

• excessively dusty or potentially explosive atmospheres;

• where there are vibrations;

•wherethereareelectromagneticelds;

• where there are aggressive atmospheres.

R134A

HFC-134a TWA 1000 ppm

2.1.1 Identication of the Type of Refrigerant Fluid Used: R134a:

Tetrauoroethane(HFC134a)100%byweightCASNo.:000811-97-2

2.1 Warning re potentially hazardous toxic substances

2. SAFETY

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.

2.1.2 Identication of the Type of Oil Used.

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.

Main Ecological Information Regarding the Types of refrigerants Fluids used.

2.1.3 Persistence and degradation

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inuencethephotochemicalsmogwhichisnotamongtheVOCvolatileorganiccompounds(asstipulatedinthe

guidelines to the UNECE). The constituent refrigerants of R407C (R32, R125 and R134a), 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.

2.1.4 Effects of discharges

2.1.5 Exposure controls and personal protection

Discharges into the atmosphere of this product does not cause a long-term contamination.

Wear protective clothing and gloves, protect your eyes and face

2.1.6 Professional exposure limits

2.2 Refrigerant handling

Users and maintenance personnel must be adequately informed about the possible risks of handling potentially toxic substan-

ces. Failure to follow such instructions can cause damage to personnel or to the unit.

2.3 Prevent inhalation of high vapor concentration

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 ventilation. 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.

2.4 Procedures to be adopted in the event of accidental release of refrigerant

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 evaporate. 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.

2.5 Main Toxicological Information Regarding the Type of refrigerant used

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.Administeroxygenifnecessary.Attemptarticialrespiration

if breathing has stopped or shows sings of stopping. If the heart stops, perform external heart massage. 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.

2.5.1 Inhalation

A high atmospheric concentration can cause anaesthetic effects with possible loss of consciousness. Prolonged exposure may lead to irregular heartbeat
