Emergency overview Colorless, volatile liquid with ethereal and faint sweetish odor. Non-
flammable material. Overexposure may cause dizziness and loss
of concentration. At higher levels, CNS depression and cardiac
arrhythmia may result from exposure. Vapors displace air and can
cause asphyxiation in confined spaces. At higher temperatures, (>
250°C, 482°F), decomposition products may include Hydrofluoric
Acid (HF) and carbonyl halides.
EXERE01 2150EN 5 (61)

Potential health hazards First aid measures
SKIN
Irritation would result from a defatting action on
tissue. Liquid contact could cause frostbite.
Promptly flush skin with water until all chemical is
removed. If there is evidence of frostbite, bathe with
lukewarm water. Do not use hot water, and do not
rub. If water is not available, cover with a clean,
soft cloth or similar covering. Get medical attention
if symptoms persist. Treatment of overexposure
should be directed at the control of symptoms and
the clinical conditions.
EYES
Liquid contact can cause severe irritation and
frostbite. Mist may cause irritation.
Immediately flush eyes with large amounts of
water for at least 15 minutes. In case of frostbite,
water should be lukewarm, not hot. Lift eyelids
occasionally to facilitate irrigation. Get medical
attention if symptoms persist.
INHALATION
The refrigerant is low in acute toxicity in animals.
When oxygen levels in air are reduced to 12–
14% by displacement, symptoms of asphyxiation,
loss of coordination, increased pulse rate and
deeper respiration will occur. At high levels, cardiac
arrhythmia may occur.
Immediately remove to fresh air. If breathing has
stopped, give artificial respiration. Use oxygen as
required, provided a qualified operator is available.
Get medical attention immediately. DO NOT give
epinephrine (adrenaline).
INGESTION
Ingestion is unlikely because of the low boiling point
of the material. Should it occur, discomfort in the
gastrointestinal tract from rapid evaporation of the
material and consequent evolution of gas would
result. Some effects of inhalation and skin exposure
would be expected.
Ingestion is unlikely because of the physical
properties and is not expected to be hazardous. DO
NOT induce vomiting unless instructed to do so by a
physician.
DELAYED EFFECTS
None known
Not applicable
Flammable properties Fire fighting measures
Material itself is not flammable. Its autoignition
temperature is 750°C, 1,382°F.

UNUSUAL FIRE AND EXPLOSION HAZARDS
The refrigerant is not flammable at ambient
temperatures and atmospheric pressure. However,
this material will become combustible when mixed
with air under pressure and exposed to strong
ignition sources. Contact with certain reactive
metals may result in formation of explosive or
exothermic reactions under specific conditions (for
example very high temperatures and/or appropriate
pressures).
SPECIAL FIRE FIGHTING PRECAUTIONS AND
INSTRUCTIONS: Firefighters should wear self-
contained, NIOSH-approved breathing apparatus
for protection against possible toxic decomposition
products. Proper eye and skin protection should
be provided. Use water spray to keep fire-exposed
containers cool.

Exposure controls, personal protection, and accidental release measures
Type Preventive measures
GENERAL Always wear recommended personal protective equipment. Where
contact with liquid is likely, such as in a spill or leak, impervious boots
and clothing should be worn.
ENGINEERING CONTROLS Provide local ventilation at filling zones and areas where leakage is
probable. Mechanical (general) ventilation may be adequate for other
operating and storage areas. Equip the installation site with any gas
alarms and/or gas protection required by local rules and regulations.
SKIN PROTECTION: General work clothing and gloves (leather)
should provide adequate protection. If prolonged contact with liquid
or gas is anticipated, insulated gloves constructed of PVA, neoprene
or butyl rubber should be used. Any contaminated clothing should be
promptly removed and washed before reuse.
PERSONAL PROTECTIVE
EQUIPMENT
EYE PROTECTION: or normal conditions, wear safety glasses.
Where there is reasonable probability of liquid contact, wear chemical
safety goggles.
DISPOSAL CONSIDERATIONS Not a hazardous waste
WARNING: DO NOT vent to the atmosphere. To comply with
provisions of the U.S. Clean Air Act, any residual must be recovered.
Contains greenhouse gas which may contribute to global warming.
The refrigerant should not be mixed with air above atmospheric pressure for leak
testing or any other purpose.
IN CASE OF A SPILL OR OTHER RELEASE
● Always wear recommended personal protective equipment.
● Evacuate unprotected personnel.
● Protected personnel should remove ignition sources and shut off leak, if without
risk, and provide ventilation.
● Unprotected personnel should not return until air has been tested and determined
safe, including low-lying areas.
● Spills and releases may have to be reported to federal and/or local authorities.
● Regarding reporting requirements refer to the Material Safety Data Sheet of the
refrigerant manufacturer.
1.2 Transportation and storage
The heat pump is top-heavy and may tip over if not handled properly.
Transport and store the heat pump in a vertical position.
Be careful when lifting the heat pump. Use appropriate lifting tools.
EXERE01 2150EN 7 (61)

Preparations for storage, transfer, and lifting
1. Check that the way is free from obstacles.
2. Use appropriate vehicle for transport.
3. At installation site check that you have proper means and resources for lifting and
placing the pump.
Storage
Before transporting to the final installation site and commissioning phase, the heat
pump must not be stored longer than needed. If the heat pump must be stored longer
than one month, the manufacturer must be informed. The heat pump must be stored in
a dry place where the temperature is at least +5 °C.
