7. Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
8. When installing or relocating air conditioner, do not let any substance other than the specified refrigerant, eg. air etc mix into
refrigeration cycle (piping). Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
9. Auxiliary devices which may be a potential ignition source shall not be installed in the duct work. Examples of such potential
ignition sources are hot surfaces with a temperature exceeding 700ºC and electric switching devices.
10. For appliances connected via an air duct system to one or more rooms, only auxiliary devices approved by the appliance manufacturer
or declared suitable with the refrigerant shall be installed in connecting ductwork.
11. 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.
12. Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.
13.
 For R32/R410A model, use piping, flare nut and tools which is specified for R32/R410A refrigerant. Using of existing (R22)
piping, flare nut and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion
and injury.
For R32 and R410A, the same flare nut on the outdoor unit side and pipe can be used.
 Since the working pressure for R32/R410A is higher than that of refrigerant R22 model, replacing conventional piping and flare
nuts on the outdoor unit side are recommended.
 If reuse piping is unavoidable, refer to instruction “IN CASE OF REUSING EXISTING REFRIGERANT PIPING”
 Thickness of copper pipes used with R32/R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.

…At least 1.8 m (horizontal installation)
Installation height for indoor unit shall be at least 1.8 m.

7
…In laundry rooms
Do not install in laundry rooms. Indoor unit is not drip proof.
When Connecting Refrigerant Tubing
Pay particular attention to refrigerant leakages.
WARNING
 When performing piping work, do not mix air except for specified refrigerant in refrigeration cycle. It causes
capacity down, and risk of explosion and injury due to high tension inside the refrigerant cycle.
 If the refrigerant comes in contact with a flame, it produces a toxic gas.
 Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury,
etc.
 Ventilate the room immediately in the event of a refrigerant gas leakage during installation. Be careful not to allow
contact of the refrigerant gas with a flame as this will cause the generation of toxic gas.
 Keep all tubing runs as short as possible.
 Use the flare method for connecting tubing.
 Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before connecting them, then
tighten the nut with a torque wrench for a leak-free connection.
 Check carefully for leaks before starting the test run.
 Do not leak refrigerant while piping work for an installation or re-installation, and while repairing refrigeration parts.
Handle liquid refrigerant carefully as it may cause frostbite.
 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.
 Electronic leak detectors may be used to detect refrigerant leaks 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 lower flammable limit (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 suitable for use with most refrigerants but 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. Oxygen free
nitrogen (OFN) shall then be purged through the system both before and during the brazing process.
When Servicing
 Contact the sales dealer or service dealer for a repair.
 Be sure to turn off the power before servicing.
 Turn the power OFF at the main power box (mains), wait at least 5 minutes until it is discharged, then
open the unit to check or repair electrical parts and wirin
g
.
 Keep your fingers and clothing away from any moving parts.
 Clean up the site after you finish, remembering to check that no metal scraps or bits of wiring have been left
inside the unit.
WARNING
 This product must not be modified or disassembled under any circumstances.
Modified or disassembled unit may cause fire, electric shock or injury.
 Do not clean inside the indoor and outdoor units by users. Engage authorized dealer or specialist for
cleaning.
 In case of malfunction of this appliance, do not repair by yourself. Contact the sales dealer or service dealer
for a repair and disposal.
CAUTION
 Ventilate any enclosed areas when installing or testing the refrigeration system.
Leaked refrigerant gas, on contact with fire or heat, can produce dangerously toxic gas.

operating electric heater. Else, it may explode and cause injury or death.
2.
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 12.7 mm (1/2 inch).]
3. 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.)
4.
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.
5. 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.
6. The user/owner or their authorized 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.
7. A logbook shall be maintained. The results of these checks shall be recorded in the logbook.
8. In case of ventilations in occupied spaces shall be checked to confirm no obstruction.
9.
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.

environmental effects.
 The check shall also take into account the effects of aging or continual vibration from sources such as compressors or fans.

11
CAUTION
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.
 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 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 #7 must be followed
to remove the refrigerant.
7.
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. (remark: OFN = oxygen free nitrogen, type of inert gas)
 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.
8.
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.

12
CAUTION
9.
Decommissioning
 Before carrying out this procedure, it is essential that the technician is completely familiar with the equipment and all its details.

 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.
10.
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.
11.
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
