ENGLISH
Do not use flammable liquids to clean the unit when it is running. If chlorinated hydrocarbon non-flammable fluids are used
for cleaning, safety precautions must be taken against any toxic vapours that may be released.
ATTENTION
Before removing any panels or dismantling any part of the unit, carry out the following operations:
- Isolate the unit from the electrical power supply by disconnecting the supply upstream of the power feeding line.
- Lock out the disconnect switch in the “OFF” position by fitting a padlock.
- Affix a tag to the disconnect switch handle stating “WORK IN PROGRESS - DO NOT SWITCH ON”.
- Do not set the electrical power switch to ON or attempt to start the unit if it has been tagged out with a warning sign.
Coloured tracers can be used in service-maintenance operations.
Inspect all refrigerant circuit unions including connectors, flanges, and more generally all critical points (open unions) in
order to prevent possible leakage of refrigerant gas.

R e f r i g e r a n t g a s e s
The units are charged with R410A refrigerant
Do not replace or mix one gas with another
because different gases are not mutually compatible.
To clean out a very heavily contaminated refrigerant system, e.g. after a refrigerant compressor burnout, a qualified
refrigeration engineer must be consulted to carry out the task.
The manufacturer’s instructions and local safety regulations should always be observed when handling and storing high
pressure gas cylinders.

R e f r i g e r a n t s s a f e t y d a t a s h e e t
Denomination:
R410A (50% Difluoromethane (R32); 50% Pentafluoroethane (R125)).
INDICATION OF HAZARDS
Major hazards:
Suffocation.
Specific hazards:
Rapid evaporation can cause frostbite.
FIRST AID MEASURES
General information:
Do not attempt to administer liquids or solids to persons who have lost consciousness.
Inhalation:
Move victims to the open air. Use oxygen or artificial respiration if necessary.
Do not administer adrenaline or similar substances.
Contact with the eyes:
Wash thoroughly with plenty of clean water for at least 15 minutes and seek medical
assistance.
Contact with the skin:
Wash immediately in plenty of clean water. Remove contaminated clothing immediately.
FIRE-FIGHTING MEASURES
Means of extinction:
Any.
Specific hazards:
Pressure rise.
Specific methods:
Cool containers with water spray.
MEASURES IN THE EVENT OF ACCIDENTAL LEAKAGE
Individual precautions:
Evacuate personnel to safe muster points. Provide adequate ventilation. Use personal
protective equipment.
Environmental precautions:
Evaporates.
Cleaning methods:
Evaporates.
HANDLING AND STORAGE
Handling
Technical measures/ precautions: Ensure the presence of sufficient ventilation and/or air extraction means in the
workplace.
Recommendations for safe use:
Do not breath fumes or aerosol.
Storage:
Close hermetically and store in a cool, dry and well-ventilated place. Store in its original
containers. Incompatible products: explosives, flammable materials, organic peroxide
CONTROL OF EXPOSURE/INDIVIDUAL PROTECTION
Control parameters:
AEL (8-h and 12-h TWA) = 1000 ml/m3 for each of the two components.
Respiratory protection:
For rescue and maintenance work in tanks use autonomous breathing apparatus. The
vapours are heavier than air and can cause suffocation, by reducing the oxygen available
for breathing.
Protection of the eyes:
Safety spectacles.
Protection of the hands:
Rubber gloves.
Hygiene measures:
Do not smoke.
