I.2 WARNINGS REGARDING POTENTIALLY TOXIC
SUBSTANCES
DANGER!
Read the following information about the
refrigerants employed carefully.
I.2.1.1 Identification of the type of refrigerant fluid
used
Difluoromethane (HFC 32) 50% by weight
N° CAS: 000075-10-5
Pentafluoroethane (HFC 125) 50% by weight
N° CAS: 000354-33-6
I.2.1.2 Identification of the type of oil used
The lubricant used in the unit is polyester oil; please refer to the
indications on the compressor data plate.
DANGER!
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.
I.2.1.3 Main ecological information regarding the
types of refrigerant fluids used
Persistence, degradation and environmental impact.
Fluid Chemical formula GWP (over 100 years)
R32 CH2F2550
R125 C2HF53400
HFC R32 and R125 refrigerants are the single components which
mixed at 50% make up R410A. They belong to the hydrofluorocarbons
group and are regulated by the Kyoto protocol (1997 and subsequent
revisions) being gases that contribute to the greenhouse effect. The
index which measures how much a certain mass of greenhouse gas
contributes to global warming is the GWP (Global Warming Potential).
The standard measure for carbon dioxide (CO2) is GWP=1.
The value of GWP assigned to each refrigerant represents the
equivalent amount in kg of CO<x2/>2<x3/> released over a period of
100 years, in order to have the same greenhouse effect of 1kg
refrigerant released over the same period of time.
The R410A mixture does not contain elements that are harmful to the
ozone layer, such as chlorine;, therefore, its ODP (Ozone Depletion
Potential) is zero (ODP=0).
Refrigerant R410
A
Components R32/R125
Composition 50/50
ODP 0
GWP (over 100 years) 2000
SAFEGUARD THE ENVIRONMENT!
Fluorocarbons fluids contained in the unit can not
be dispersed in the atmosphere because they are
fluids that produce greenhouse gases.
R32 and R125 are hydrocarbons which decompose rapidly into the
lower atmosphere (troposphere). Decomposition by-products are highly
dispersible and thus have a very low concentration. They do not affect
photochemical smog (that is, they are not classified among VOC volatile
organic compounds, according to the guidelines established by the
UNECE agreement).
Effects on effluent treatment
Waste products released into the atmosphere do not cause long-term
water contamination.
Personal protection/exposure control
Use protective clothing and gloves; protect eyes and face.
Professional exposure limits:
R410A
HFC 32 TWA 1000 ppm
HFC 125 TWA 1000 ppm
Handling
DANGER!
Users and maintenance personnel must be
adequately informed about the risks of handling
potentially toxic substances. Failure to observe the
aforesaid indications may cause personal injury or
damage the unit.
Avoid inhalation of high concentrations of vapour. The atmospheric
concentration must be reduced as far as possible and maintained at this
minimum level, below professional exposure limits. The vapours are
heavier than air, and thus hazardous concentrations may form close to
the floor, where overall ventilation may be poor. In this case, ensure
adequate ventilation. Avoid contact with naked flames and hot surfaces,
which could lead to the formation of irritant and toxic decomposition by-
products. Do not allow the liquid to come into contact with eyes or skin.
Procedures in case of accidental refrigerant leakage
Ensure adequate personal protection (using means of respiratory
protection) during clean-up operations. If the conditions are sufficiently
safe, isolate the source of leak.
If the extent of the spill is limited, let the material evaporate, as long as
adequate ventilation can be ensured. If the spill is considerable,
ventilate the area adequately.
Contain the spilt material with sand, soil, or other suitable absorbent
material.
Prevent the liquid from entering drains, sewers, underground facilities or
manholes, because suffocating vapours may form.
I.2.1.4 Main toxicological information on the type
of refrigerant used
Inhalation
A high atmospheric concentration can cause anaesthetic effects with
possible loss of consciousness. Prolonged exposure may lead to an
irregular heartbeat and cause sudden death.
Higher concentrations may cause asphyxia due to the reduced oxygen
content in the atmosphere.
Contact with skin
Splashes of nebulised liquid can produce frostbite. Probably not
hazardous if absorbed through the skin. Repeated or prolonged contact
may remove the skin's natural oils, with consequent dryness, cracking
and dermatitis.
Contact with eyes
Splashes of liquid may cause frostbite.
Ingestion
While highly improbable, may produce frostbite.
I.2.1.5 First aid measures
Inhalation
Move the person away from the source of exposure, keep him/her warm
and let him/her rest. Administer oxygen if necessary. Attempt artificial
respiration if breathing has stopped or shows signs of stopping.
In the case of cardiac arrest carry out heart massage and seek
immediate medical assistance.
Contact with skin
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.
Contact with eyes
Rinse immediately using an eyewash or clean water, keeping eyelids
open, for at least ten minutes.
Seek medical assistance.
Ingestion
Do not induce vomiting. If the injured person is conscious, rinse his/her
mouth with water and make him/her drink 200-300 ml of water.
Seek immediate medical assistance.
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.

accessibility of refrigerant and electrical
connections.
The unit is designed for outdoor installation. The unit must be installed
in compliance with the minimum recommended technical spaces,
bearing in mind the access to the water and electrical connections. The
unit should be correctly levelled and positioned on a supporting surface
capable of sustaining its full weight. It must not be installed on brackets
or shelves.

IMPORTANT!
Incorrect positioning or installation of the unit may
amplify noise levels and vibrations generated
during operation.
The following accessories are available to reduce noise and vibration:
KSA - Anti-vibration mountings.
When installing the unit, bear the following in mind:
non-soundproofed reflecting walls near the unit may increase the
total sound pressure level reading near the appliance by as much as 3
dB(A) for every surface;
install suitable anti-vibration mountings under the unit to avoid
transmitting vibrations to the building structure;
piping should be supported in a rigid and solid structures. If the pipes
are routed through walls or panels, insulate with elastic sleeves. If, after
installation and start-up of the unit, structural vibrations are observed in
the building which provoke such strong resonance that noise is
generated in other parts of the building, refer to a qualified acoustic
technician for a complete analysis of the problem.

II.2.2 REFRIGERANT CONNECTIONS
IMPORTANT!
It is very important for the cooling connections to
be implemented with great care by specialised
personnel.
II.2.2.1 Preparation of cooling lines
The refrigerant piping for the connection to the evaporator section must
be made of copper pipes for refrigeration systems of the type EN
12735, electrolytic, annealed, degreased and deoxidized. Also make
sure that there are no impurities or humidity in the piping which could be
extremely harmful for the cooling circuit. The cooling lines must also be
insulated individually covered in closed cell fireproof expanded material
at least 9 mm thick.
The table below shows the maximum equivalent lengths of the
connection pipes with the evaporator section and the relative diameters.

(*) The equivalent lenghth can be roughly obtained by adding 1.2
m for each bend and 1 m for each change of cross-section to the
straight pipes
Fig. 10
The maximum difference allowed between the machine and the
evaporating section is 8 m, and the maximum equivalent length of the
line connection is 25 m.
Bigger height differences are possible provided siphons are included
every 6 m on the gas line. The siphons must have a height appropriate
to the section of the pipe. In the installation of the pipes should operate
with care and with the aid of bending of the type suitable to the diameter
of the pipe, to avoid possible deformations. Bend the tubes by cutting
the insulation in order to free up the tube and then carefully reposition
the insulation if removed, joining the joints with tape or mastic suitable
and fix the pipes by means of brackets. The horizontal suction line must
be sloped towards the compressor at least 1% is that the compressor is
on top is that it is lower than the evaporating section. The exit of the
evaporator section must be realized a siphon to allow the oil drag
towards the compressor (Fig. 10).
II.2.2.2 Refrigerant charge
DANGER!
The refrigerant gas in the machine may be at an
elevated pressure. Use appropriate personal
protective equipment during installation,
maintenance and repair.
The units are supplied with a charge of refrigerant (R410A) indicated on
the serial number plate.
