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 qualiﬁed with additional safety information (text or other symbols).

Safety symbols combined in accordance with ISO 3864-2:

WSA Water chiller

The unit is not suitable for operations in environments:

• excessively dusty or potentially explosive atmospheres;

• where there are vibrations;

• where there are electromagnetic ﬁelds;

• where there are aggressive atmospheres

The product label should never be removed from the unit.

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.

1.9 Limitations and prohibited use

1.10 Unit identiﬁcation

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:

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

2.1.1 Identiﬁcation of the Type of Refrigerant Fluid Used: R410A

2.1.2 Identiﬁcation of the Type of Oil Used.

2. SAFETY

• Diﬂuoromethane (HFC-32) 50% by weight CAS No.: 000075-10-5

• Pentaﬂuoroethane (HFC-125) 50% by weight CAS No.: 000354-33-6

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 inﬂuence 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.

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

Wear protective clothing and gloves, protect your eyes and face

Main Ecological Information Regarding the Types of refrigerants Fluids used.

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

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