Safety Precautions
WARNING
This appliance is filled with R32 (mildly flammable refrigerant). If the
refrigerant is leaked and exposed to an external ignition source, there is a
risk of fire.
Indoor unit and outdoor unit
The appliance shall be installed, and/or operated in a room with floor area
larger than Amin (m²) and keep away from ignition sources, such as
heat/sparks/open flame or hazardous areas such as gas appliances, gas cooking,
reticulated gas supply systems or electric cooking appliances, etc. (Refer to
Table A of Installation instructions table for Amin (m²))
Be aware that refrigerant may not contain an odour, highly recommended to
ensure suitable flammable refrigerant gas detectors are present, operating and
able to warn of a leak.
Keep any required ventilation openings clear of obstruction.
Do not pierce or burn as the appliance is pressurized. Do not expose the
appliance to heat, flame, sparks, or other sources of ignition. Else it may
explode and cause injury or death.
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 flare nuts with the R32 and R410A piping
and flare nuts on the outdoor unit side. For R32 and R410A, the same flare 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.] 24
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 certified personnel
in the use of flammable 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 certified. · 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 flames, 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
confirm 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 certified operating personnel are instructed on the
basis of the instruction manual about the construction, supervision, operation
and maintenance of the refrigerating system, as well as the safety measures to
be observed, and the properties and handling of the refrigerant used. · The
general requirement of trained and certified personnel are indicated as below:
a) Knowledge of legislation, regulations
and standards relating to flammable refrigerants; and, b) Detailed knowledge
of and skills in handling flammable refrigerants, personal protective
equipment, refrigerant leakage prevention, handling of cylinders, charging,
leak detection, recovery and disposal; and, c) Able to understand and to apply
in practice the requirements in the national legislation, regulations and
Standards; and, d) Continuously undergo regular and further training to
maintain this expertise. e) Air-conditioner piping in the occupied space shall
be installed in such a way to protect against accidental damage in operation
and service.
f) Precautions shall be taken to avoid excessive vibration or pulsation to
refrigerating piping.
g) Ensure protection devices, refrigerating piping and fittings are well
protected against adverse environmental effects (such as the danger of water
collecting and freezing in relief pipes or the accumulation of dirt and
debris).
h) Expansion and contraction of long runs piping in refrigerating systems
shall be designed and installed securely (mounted and guarded) to minimize the
likelihood hydraulic shock damaging the system.
i) Protect the refrigerating system from accidental rupture due to moving
furniture or reconstruction activities.
j) To ensure no leaking, field-made refrigerant joints indoors shall be
tightness tested. The test method shall have 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). No leak shall be detected.
1. Installation (Space) · Product with flammable refrigerants, shall
be installed according to the minimum room area, Amin (m²) mentioned in Table
A of the Installation Instructions. · In case of field charge, the effect on

has contained flammable refrigerant shall use any sources of ignition in such
a manner that it may lead to the risk of fire or explosion. They must not be
smoking when carrying out such work. · All possible ignition sources,
including cigarette smoking, should be kept sufficiently far away from the
site of installation, repairing, removing and disposal, during which flammable
refrigerant can possibly be released to the surrounding space. · Prior to work
taking place, the area around the equipment is to be surveyed to make sure
that there are no flammable hazards or ignition risks. · “No Smoking” signs
shall be displayed.
2-6. Ventilated area · Ensure that the area is in the open or that it is
adequately ventilated before breaking into the system or conducting any hot
work. · A degree of ventilation shall continue during the period that the work
is carried out. · The ventilation should safely disperse any released
refrigerant and preferably expel it externally into the atmosphere.
26
2-7. Checks to the refrigerating equipment · Where electrical components are
being
changed, they shall be fit for the purpose and to the correct specification. ·
At all times the manufacturer’s maintenance and service guidelines shall be
followed. · If in doubt consult the manufacturer’s technical department for
assistance. · The following checks shall be applied to installations using
flammable refrigerants. – The actual refrigerant charge is in
accordance with the room size within which the refrigerant containing parts

refrigerant. – Marking to the equipment continues to be visible and legible.
Markings and signs that are illegible shall be corrected. – Refrigerating pipe
or components are installed in a position where they are unlikely to be
exposed to any substance which may corrode refrigerant containing components,
unless the components are constructed of materials which are inherently
resistant to being corroded or are properly protected against being so
corroded.
2-8. Checks to electrical devices · Repair and maintenance to electrical
components shall include initial safety checks and component inspection
procedures. · Initial safety checks shall include but not limit to:- That
capacitors are discharged: this
shall be done in a safe manner to avoid possibility of sparking. – That there
no live electrical components and wiring are exposed while charging,
recovering or purging the system. – That there is continuity of earth bonding.
· At all times the manufacturer’s maintenance and service guidelines shall be
followed. · If in doubt consult the manufacturer’s technical department for
assistance. · If a fault exists that could compromise safety, then no

dealt with. · If the fault cannot be corrected immediately but it is necessary
to continue operation, an adequate temporary solution shall be used. · The
owner of the equipment must be informed or reported so all parties are advised
thereinafter.
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 specification, damage to seals, incorrect
fitting of glands, etc. · Ensure that apparatus is mounted securely. · Ensure
that seals or sealing materials have not degraded such that they no longer
serve the purpose of preventing the ingress of flammable atmospheres. ·
Replacement parts shall be in accordance with the manufacturer’s
specifications. 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 flammable atmosphere. · The test apparatus shall be
at the correct rating. · Replace components only with parts specified by the
manufacturer. Unspecified parts by manufacturer may result ignition of
refrigerant in the atmosphere from a leak.
5. Cabling · Check that cabling will not be subject
to wear, corrosion, excessive pressure, vibration, sharp edges or any other
adverse environmental effects. · The check shall also take into account the
effects of aging or continual vibration from sources such as compressors or
fans.
6. Detection of flammable refrigerants · Under no circumstances shall
potential
sources of ignition be used in the searching or detection of refrigerant
leaks. · A halide torch (or any other detector using a naked flame) shall not
be used.
7. The following leak detection methods are deemed acceptable for all
refrigerant systems
· No leaks shall be detected using detection equipment with sensitivity to
detect leakage of 5g/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 flammable 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 confirmed.
· Leak detection fluids are also suitable for use with most refrigerants, for
example, bubble method and fluorescent 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 flames 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.

Safety Precautions
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
flammability 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 fill until the working pressure is achieved, then
venting to atmosphere, and finally pulling down to a vacuum. · This process
shall be repeated until no refrigerant is within the system. · When the final
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.
28
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 fill 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 fire 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 fill cylinders. (No more than 80 % volume liquid charge).
i) Do not exceed the maximum working pressure of the cylinder, even
temporarily.
j) When the cylinders have been filled 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 fire 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 flammable 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 flammable 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 flammable
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.
