Precaution for using R32
refrigerant
The basic installation work procedures are the
same as conventional refrigerant (R410A, R22)
models.
Since the working pressure is higher
than that of refrigerant R22 models,
some of the piping and installation and
service tools are special. Especially,
when replacing a refrigerant R22
model with a new refrigerant
R32 model, always replace the
conventional piping and fl are nuts with
the R32 and R410A piping and fl are
nuts on the outdoor unit side.
For R32 and R410A, the same fl are
nut on the outdoor unit side and pipe
can be used.
The mixing of different refrigerants
within a system is prohibited. Models
that use refrigerant R32 and R410A
have a different charging port thread
diameter to prevent erroneous
charging with refrigerant R22 and for
safety.
Therefore, check beforehand. [The
charging port thread diameter for R32
and R410A is 1/2 inch.]
Must always ensure that foreign matter
(oil, water, etc.) does not enter the
piping. Also, when storing the piping,
securely seal the opening by pinching,
taping, etc. (Handling of R32 is similar
to R410A.)
• Operation, maintenance, repairing
and refrigerant recovery should be
carried out by trained and certifi ed
personnel in the use of fl ammable
refrigerants and as recommended
by the manufacturer. Any personnel
conducting an operation, servicing
or maintenance on a system or
associated parts of the equipment
should be trained and certifi ed.
• Any part of refrigerating circuit
(evaporators, air coolers, AHU,
condensers or liquid receivers) or
piping should not be located in the
proximity of heat sources, open
fl ames, operating gas appliance or an
operating electric heater.
• The user/owner or their authorised
representative shall regularly check
the alarms, mechanical ventilation
and detectors, at least once a
year, where as required by national
regulations, to ensure their correct
functioning.
• A logbook shall be maintained. The
results of these checks shall be
recorded in the logbook.
• In case of ventilations in occupied
spaces shall be checked to confi rm
no obstruction.
• Before a new refrigerating system
is put into service, the person
responsible for placing the system
in operation should ensure that
trained and certifi ed operating
personnel are instructed on the
basis of the instruction manual
about the construction, supervision,
operation and maintenance of the

13
English
3. Repairs to sealed components
• During repairs to sealed components,
all electrical supplies shall be
disconnected from the equipment
being worked upon prior to any
removal of sealed covers, etc.
• If it is absolutely necessary to have
an electrical supply to equipment
during servicing, then a permanently
operating form of leak detection shall
be located at the most critical point
to warn of a potentially hazardous
situation.
• Particular attention shall be paid
to the following to ensure that by
working on electrical components, the
casing is not altered in such a way
that the level of protection is affected.
This shall include damage to cables,
excessive number of connections,
terminals not made to original
specifi cation, damage to seals,
incorrect fi tting of glands, etc.
• Ensure that apparatus is mounted

• Ensure that seals or sealing materials
have not degraded such that they
no longer serve the purpose of
preventing the ingress of fl ammable
atmospheres.
• Replacement parts shall be in
accordance with the manufacturer’s
specifi cations.
NOTE: The use of silicon sealant may
inhibit the effectiveness of some types
of leak detection equipment.
Intrinsically safe components do not
have to be isolated prior to working on
them.
4. Repair to intrinsically safe
components
• Do not apply any permanent inductive
or capacitance loads to the circuit
without ensuring that this will not
exceed the permissible voltage and
current permitted for the equipment
in use.
• Intrinsically safe components are
the only types that can be worked
on while live in the presence of a

Safety precautions

14
Safety precautions
7. The following leak detection
methods are deemed
acceptable for all refrigerant
systems
• No leaks shall be detected when
using detection equipment with a
sensitivity of 5 grams per year of
refrigerant or better under a pressure
of at least 0.25 times the maximum
allowable pressure (>1.04 MPa, max
4.15 MPa), for example, a universal
sniffer.
• Electronic leak detectors may be
used to detect fl ammable refrigerants,
but the sensitivity may not be
adequate, or may need re-calibration.
(Detection equipment shall be
calibrated in a refrigerant-free area.)
• Ensure that the detector is not a
potential source of ignition and is
suitable for the refrigerant used.
• Leak detection equipment shall be
set at a percentage of the LFL of the
refrigerant and shall be calibrated
to the refrigerant employed and the
appropriate percentage of gas (25 %
maximum) is confi rmed.
• Leak detection fl uids are also suitable
for use with most refrigerants,
for example, bubble method and
fl uorescent method agents. The use
of detergents containing chlorine shall
be avoided as the chlorine may react
with the refrigerant and corrode the
copper pipe-work.
• If a leak is suspected, all naked
fl ames shall be removed/
extinguished.
• If a leakage of refrigerant is found
which requires brazing, all of the
refrigerant shall be recovered from
the system, or isolated (by means
of shut off valves) in a part of the
system remote from the leak. The
precautions in #8 must be followed to
remove the refrigerant.
8. Removal and evacuation
• When breaking into the refrigerant
circuit to make repairs – or for
any other purpose – conventional
procedures shall be used. However,
it is important that best practice
is followed since fl ammability is
a consideration. The following
procedure shall be adhered to:
remove refrigerant -> purge the circuit
with inert gas -> evacuate -> purge
with inert gas -> open the circuit by
cutting or brazing.
• The refrigerant charge shall be
recovered into the correct recovery
cylinders.
• The system shall be purged with OFN
to render the appliance safe.
• This process may need to be
repeated several times.
• Compressed air or oxygen shall not
be used for this task.
• Purging shall be achieved by
breaking the vacuum in the system
with OFN and continuing to fi ll until
the working pressure is achieved,
then venting to atmosphere, and
fi nally pulling down to a vacuum.
• This process shall be repeated until
no refrigerant is within the system.
• When the fi nal OFN charge is used,
the system shall be vented down to
atmospheric pressure to enable work
to take place.
• This operation is absolutely vital if
brazing operations on the pipe work
are to take place.
• Ensure that the outlet for the
vacuum pump is not close to any
potential ignition sources and there is
ventilation available.
OFN = oxygen free nitrogen,
type of inert gas.

15
English
9. Charging procedures
• In addition to conventional
charging procedures, the following
requirements shall be followed.
- Ensure that contamination of
different refrigerants does not occur
when using charging equipment.
- Hoses or lines shall be as short as
possible to minimize the amount of
refrigerant contained in them.
- Cylinders shall be kept in an
appropriate position according to
the instructions.
- Ensure that the refrigerating system
is earthed prior to charging the
system with refrigerant.
- Label the system when charging is
complete (if not already).
- Extreme care shall be taken not to
over fi ll the refrigerating system.
• Prior to recharging the system it shall
be pressure tested with OFN (refer
to #7).
• The system shall be leak tested on
completion of charging but prior to
commissioning.
• A follow up leak test shall be carried
out prior to leaving the site.
• Electrostatic charge may accumulate
and create a hazardous condition
when charging and discharging the
refrigerant.To avoid fi re or explosion,
dissipate static electricity during
transfer by grounding and bonding
containers and equipment before
charging/discharging.
10. Decommissioning
• Before carrying out this procedure,
it is essential that the technician
is completely familiar with the
equipment and all its details.
• It is recommended good practice that
all refrigerants are recovered safely.
• Prior to the task being carried
out, an oil and refrigerant sample
shall be taken in case analysis is
required prior to re-use of recovered
refrigerant.
• It is essential that electrical power
is available before the task is
commenced.
a) Become familiar with the
equipment and its operation.
b) Isolate system electrically.
c) Before attempting the procedure
ensure that:
• mechanical handling equipment is
available, if required, for handling
refrigerant cylinders;
• all personal protective equipment
is available and being used
correctly;
• the recovery process is supervised
at all times by a competent person;
• recovery equipment and cylinders
conform to the appropriate
standards.
d) Pump down refrigerant system, if
possible.
e) If a vacuum is not possible, make
a manifold so that refrigerant can
be removed from various parts of
the system.
f) Make sure that cylinder is situated
on the scales before recovery
takes place.
g) Start the recovery machine and
operate in accordance with
instructions.
h) Do not over fi ll cylinders. (No more
than 80 % volume liquid charge).

Safety precautions
i) Do not exceed the maximum
working pressure of the cylinder,
even temporarily.
j) When the cylinders have been
fi lled correctly and the process
completed, make sure that the
cylinders and the equipment are
removed from site promptly and all
isolation valves on the equipment
are closed off.
k) Recovered refrigerant shall not be
charged into another refrigerating
system unless it has been cleaned
and checked.
• Electrostatic charge may accumulate
and create a hazardous condition
when charging or discharging the
refrigerant.To avoid fi re or explosion,
dissipate static electricity during
transfer by grounding and bonding
containers and equipment before
charging/discharging.
11. Labelling
• Equipment shall be labelled stating
that it has been de-commissioned
and emptied of refrigerant.
• The label shall be dated and signed.
• Ensure that there are labels on the
equipment stating the equipment
contains fl ammable refrigerant.
12. Recovery
• When removing refrigerant from
a system, either for servicing or
decommissioning, it is recommended
good practice that all refrigerants are
removed safely.
• When transferring refrigerant
into cylinders, ensure that only
appropriate refrigerant recovery
cylinders are employed.
• Ensure that the correct number of
cylinders for holding the total system
charge are available.
• All cylinders to be used are
designated for the recovered
refrigerant and labelled for that
refrigerant (i.e. special cylinders for
the recovery of refrigerant).
• Cylinders shall be complete with
pressure relief valve and associated
shut-off valves in good working order.
• Recovery cylinders are evacuated
and, if possible, cooled before
recovery occurs.
• The recovery equipment shall be
in good working order with a set of
instructions concerning the equipment
that is at hand and shall be suitable
for the recovery of fl ammable
refrigerants.
• In addition, a set of calibrated
weighing scales shall be available
and in good working order.
• Hoses shall be complete with leak-
free disconnect couplings and in good
condition.
• Before using the recovery machine,
check that it is in satisfactory working
order, has been properly maintained
and that any associated electrical
components are sealed to prevent
ignition in the event of a refrigerant
release.Consult manufacturer if in
doubt.
• The recovered refrigerant shall be
returned to the refrigerant supplier
in the correct recovery cylinder, and
the relevant Waste Transfer Note
arranged.
• Do not mix refrigerants in recovery
units and especially not in cylinders.
• If compressors or compressor oils are
to be removed, ensure that they have
been evacuated to an acceptable
level to make certain that fl ammable
refrigerant does not remain within the
lubricant.
• The evacuation process shall be
carried out prior to returning the
compressor to the suppliers.
• Only electric heating to the
compressor body shall be employed
to accelerate this process.
• When oil is drained from a system, it
shall be carried out safely.
