Material Safety Data
Components Material PENTAFLUOROETHANE (HFC-125) DIFLUOROMETHANE (HFC-32)
CAS Number 354-33-6 75-10-5
% 50 50
Inhalation of high concentrations of vapour is harmful and may cause heart irregularities, unconsciousness,
or death. Intentional misuse or deliberate inhalation may cause death without warning. Vapour reduces
oxygen available for breathing and is heavier than air. Liquid contact can cause frostbite.
At flame temperatures, this material can decompose to hydrogen fluoride which can be lethal at much lower
concentrations.
Overexposure to the vapours by inhalation may include temporary nervous system depression with
anaesthetic effects such as dizziness, headache, confusion, incoordination, and loss of consciousness.
Higher exposures to the vapours may cause temporary alteration of the heart's electrical activity with
irregular pulse, palpitations, or inadequate circulation. Gross overexposure may be fatal. Skin contact with
the liquid may cause frostbite.
Individuals with preexisting diseases of the central nervous or cardiovascular system may have increased
susceptibility to the toxicity of increased exposures.
Carcinogenicity Information
None of the components present in this material at concentrations equal to or greater than 0.1% are listed
by IARC, NTP, OSHA or ACGIH as a carcinogen.
If inhaled, immediately remove to fresh air. Keep person calm.
If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
Skin Contact Flush area with lukewarm water. Do not use hot water. If frostbite has occurred, call a physician.
Eye Contact In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a physician.
Ingestion Do not induce vomiting. Give plenty of water in sips
Notes to Physicians
THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO ARRHYTHMIAS. Catecholamines
such as adrenaline, and other compounds having similar effects, should be reserved for emergencies and
then used only with special caution.
Flash Point : No flash point
Flammable Limits in Air, % by Volume:
LEL : None per ASTM E681
UEL : None per ASTM E681
Autoignition: Not determined
Cylinders may rupture under fire conditions. Decomposition may occur.
Contact of welding or soldering torch flame with high concentrations of refrigerant can result in visible
changes in the size and colour of torch flames. This flame effect will only occur in concentrations of product
well above the recommended exposure limit, therefore stop all work and ventilate to disperse refrigerant
vapours from the work area before using any open flames.
R-410A is not flammable in air at temperatures up to 100 deg C (212 deg F) at atmospheric pressure.
However, mixtures of R-410A with high concentrations of air at elevated pressure and/or temperature can
become combustible in the presence of an ignition source. R-410A can also become combustible in an
oxygen enriched environment (oxygen concentrations greater than that in air). Whether a mixture
containing R-410A and air, or R-410A in an oxygen enriched atmosphere becomes combustible depends
on the inter-relationship of 1) the temperature 2) the pressure, and 3) the proportion of oxygen in the
mixture. In general, R-410A should not be allowed to exist with air above atmospheric pressure or at high
temperatures; or in an oxygen enriched environment. For example: R-410A should NOT be mixed with air
under pressure for leak testing or other purposes.

Low pressure liquid refrigerant enters the evaporator and is evaporated and superheated by the heat energy absorbed
from the chilled liquid. Low pressure vapour enters the compressor where pressure and superheat are increased. The
high pressure vapour is fed to the air cooled condenser coil and fans where heat is removed. The fully condensed
and subcooled liquid passes through the expansion valve where pressure is reduced and further cooling takes place
before returning to the evaporator.

3. Transportation, Handling and Storage
Delivery and Storage
To ensure consistent quality and maximum reliability,
all units are tested and inspected before leaving the
factory. Units are shipped completely assembled
and containing refrigerant under pressure. Units are
shipped without export crating unless crating has been
VSHFL¿HGRQWKH6DOHV2UGHU
If the unit is to be put into storage, prior to installation,
the following precautions should be observed:
Ensure that all openings, such as water connections,
are securely capped.
The unit should be stored in a location where there is
minimal activity in order to limit the risk of accidental
physical damage.
To prevent inadvertent operation of the pressure relief
devices the unit must not be steam cleaned.
It is recommended that the unit is periodically inspected
during storage.
Inspection
Remove any transit packing and inspect the unit to
ensure that all components have been delivered and
that no damage has occurred during transit. If any
damage is evident, it should be noted on the carrier’s
freight bill and a claim entered in accordance with the
instructions given on the advice note.
Major damage must be reported immediately to your
local Johnson Controls representative.
Moving the unit
Prior to moving the unit, ensure that the installation site
is suitable for installing the unit and is easily capable
of supporting the weight of the unit and all associated
services.
The unit should be lifted using lifting lugs and a spreader
