I.1.6 Safety Information; I.1.7 Information About Use Restrictions; I.1.8 Warnings About Potentially Toxic Substances - RHOSS CMA/E 14 Gebrauchsanweisung

I.1.6 SAFETY INFORMATION
DANGER!
Always install an automatic general isolator in a
protected area near the appliance, of suitable size
and breaking capacity, with a 3mm minimum
opening distance between the contacts.
Earthing is compulsory by law to ensure the safety
of the user when the machine is running. Electrical
connections must be made in compliance with
established regulations and the wiring diagrams
supplied with the unit.
ATTENTION
Installation may only be carried out by qualified
technicians, authorised to work with air-
conditioning and refrigeration systems.
I.1.7 INFORMATION ABOUT USE RESTRICTIONS
DANGER!
CMA/E and CMA/EX are condenser units with air-
cooled condensation, and CMR/E are reverse cycle
heat pumps with air-cooled evaporation /
condensation; they are designed and constructed
exclusively for this purpose, and any use other than
that described is EXPRESSLY PROHIBITED.
DANGER!
All operations of installation, maintenance, repair,
replacement of any component, charging or topping
up of coolant and disassembly of the unit must be
carried out exclusively by trained technicians,
qualified to work with conditioning and cooling
systems.
I.1.8 WARNINGS ABOUT POTENTIALLY TOXIC
SUBSTANCES
DANGER!
Read with care the following information about the
refrigerants used.
I.1.8.1 Identification of the type of coolant used
○ MODEL CMA/E – CMR/E
• Chlorodifluoromethane (HCFC 22)
CAS No: 000075-45-6
CAS No: 200-871-9
○ CMA/EX:
• Difluoromethane (HFC32) 23% by weight
CAS No: 000075-10-5
• Pentafluoroethane (HFC125) 25% by weight
CAS No: 000354-33-6
• 1, 1, 1, 2 - Tetrafluoroethane (HFC134a) 52% by weight
CAS N°: 000811-97-2
I.1.8.2 Identification of type of oil used
The lubrication oil used in the units is mineral type for CMA/E and
CMR/E units, running on R22 refrigerant, and polyester type for
CMA/EX units running on R407c (R32/R125/R134a).
In all cases, refer to the instructions on the plate attached to the
compressor
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 producers.
I.1.8.3 Main ecological information regarding the
types of refrigerant employed
ENVIRONMENT SAFEGUARD!
Carefully read the following ecological information
and provisions.
• Persistence and degradation
Decomposes with relative rapidity in the lower atmosphere
(troposphere). Decomposition by-products are highly dispersible and
thus have a very low concentration. They have no influence on
photochemical smog (that is, they are not classified among VOC
volatile organic compounds, according to the guidelines established by
the UNECE agreement). The ozone destruction potential (ODP) of R22
fluid is 0.0055, measured against a standard ODP equal to 1 for CFC
11 (according to UNEP definitions), whereas R32, R125 and R134a
fluids (contained in CMA/EX units) do not destroy the ozone layer. The
substances are regulated by the Montreal protocol (1992 revision).
• Effects on effluent treatment
Waste products released into the atmosphere do not provoke long-term
water contamination.
• Individual protection/exposition
Use protective clothing and gloves; protect eyes and face.
• Professional exposure limits:
R22
HCFC 22 TWA 1000 ppm – 3540 mg/m
STEL 1250 ppm – 4430 mg/m
R407c
HFC 32 TWA 1000 ppm
HFC 125 TWA 1000 ppm
HFC 134a TWA 1000 ppm – 4240 mg/m
• Handling
DANGER!
The user 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 vapor. Atmospheric
concentration must be reduced to a minimum and maintained at this
minimum level, well beneath professional exposure limits. Vapor is
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 irritating and toxic decomposition
by-products. Do not allow the liquid to come into contact with eyes or
skin.
• Procedure in case of accidental coolant escape
Ensure adequate personal protection (using means of respiratory
protection) during clean-up operations. If the conditions are sufficiently
safe, isolate the source of leaking. If the amount 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.
Prevent the liquid from entering any discharge pipes, drains, sewers,
underground facilities or manholes because suffocating vapours may
form.
I.1.8.4 General toxicological information on type of
refrigerant used
DANGER!
Adhere scrupulously to the warnings and first aid
procedures indicated below.
• Inhalation
A high atmospheric concentration can cause anesthetic effects with
possible loss of consciousness. Prolonged exposure may lead to an
irregular heart beat and provoke sudden death.
Higher concentrations may cause asphyxia due to the reduced oxygen
level in the atmosphere.
• Contact with skin
Splashes of nebulized liquid can provoke 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
Splashing liquid may cause frostbite.
• Ingestion
While highly improbable, may provoke frostbite.
