Do not install or use the air conditioner in any area where the atmosphere contains combustible gases or where the
atmosphere is contaminated. Avoid any chemicals coming in contact with your air conditioner.
Do not store anything directly on top of the air conditioner.
The appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory or
mental capabilities if they have been given supervision or instruction concerning the use of the appliance in a safe
way and understand the hazards involved. Children shall not play with the appliance. Cleaning and maintenance shall
not be made by children without supervision.
This appliance is not intended for people（including children）with reduced physical, sensory or mental capabilities, or
lack of experience and knowledge unless they have been given supervision or instruction concerning the use of the
appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with
the appliance.
Use two or more people to move and install an air conditioner.
Never operate the air conditioner without the filters in place.
Do not use the air conditioner near a bathtub, shower or wash basin, or another wet area.
Do not use means to accelerate the defrosting process or to clean, other than those recommended by the
manufacturer.
The appliance shall be stored in a room without continuously operating ignition sources (for example open flames, an
operating gas appliance, or an operating electric heater. Do not pierce or burn.
Be aware that refrigerants may not contain an odor.
–The maximum refrigerant charge amount: 12.5Oz
The appliance shall be stored to prevent mechanical damage from occurring.
Any person who is involved with working on or breaking into a refrigerant circuit should hold a currently valid
certificate from an industry-accredited assessment authority, which authorizes their competence to handle
refrigerants safely by an industry-recognized assessment specification. Servicing shall only be performed as
recommended by the equipment manufacturer. Maintenance and repair requiring the assistance of other skilled
personnel shall be carried out under the supervision of the person competent in the use of flammable refrigerants.
Before beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the
risk of ignition is minimized. Work shall be undertaken under a controlled procedure to minimize the risk of
flammable gas or vapor being present while the work is being performed. All maintenance staff and others working
in the local area shall be instructed on the nature of the work being carried out. Work in confined spaces shall be
avoided. The area around the workspace shall be sectioned off. Ensure that the conditions within the area have been
made safe by control of flammable material.
The area shall be checked with an appropriate refrigerant detector before and during work, to ensure the technician
is aware of potentially flammable atmospheres. Ensure that the leak detection equipment being used is suitable for
use with flammable refrigerants, i.e., no sparking, adequately sealed, or intrinsically safe.
If any hot work is to be conducted on the refrigeration equipment or any associated parts, appropriate fire
extinguishing equipment shall be available to hand. Have a dry powder or CO² fire extinguisher adjacent to the
charging area.
No person carrying out work about a refrigeration system that involves exposing any pipe work that contains or 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. All possible ignition sources, including cigarette smoking, should be kept sufficiently far away from the
site of installation, repair, removal, and disposal, during which flammable refrigerant can be released into the
surrounding space. Before work takes 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.
Ensure that the area is outdoors or 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.
Do not apply any permanent inductive or capacitance loads to the circuit without ensuring that this will not exceed
the permissible voltage and currently permitted for the equipment in use. Intrinsically safe components are the only
types that can be worked on while living 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. Other parts may result in the

3
ignition of refrigerant in the atmosphere from a leak.
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.
Under no circumstances shall potential sources of ignition be used in the search or detection of refrigerant leaks. A
halide torch (or any other detector using a naked flame) shall not be used.
Electronic leak detectors shall 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 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 leakage of refrigerant
is found which requires brazing, all of the refrigerants shall be recovered from the system, or isolated (using 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 breaking into the refrigerant circuit to make repairs – or for any other purpose – conventional procedures shall
be used. However, best practices must be followed since flammability is a consideration. The following procedure
shall be adhered to:
- Remove refrigerant;
- Purge the circuit with inert gas;
- Evacuate;
- Purge again 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 “flushed” with OFN
to render the unit safe. This process may need to be repeated several times. Compressed air or oxygen shall not be
used for this task. Flushing 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 the 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 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
ignition sources and there is ventilation available.
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 upright.
–Ensure that the refrigeration system is earthed before charging the system with refrigerant.
–Label the system when charging is complete (if not already).
–Extreme care shall be taken not to overfill the refrigeration system.
Before charging the system, it shall be pressure tested with OFN. The system shall be leak tested on completion of
charging but before commissioning. A follow-up leak test shall be carried out before leaving the site.
Before carrying out this procedure, the technician must be completely familiar with the equipment and all its detail.
It is recommended good practice that all refrigerants are recovered safely. Before the task is carried out, an oil and
refrigerant sample shall be taken in case analysis is required before the re-use of reclaimed refrigerant. Electrical
power must be available before the task begins.
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 the 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 the cylinder is situated on the scales before recovery takes place.

4
g) Start the recovery machine and operate it by the manufacturer's instructions.
h) Do not overfill 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 the site promptly and all isolation valves on the equipment are closed off.
k) Recovered refrigerant shall not be charged into another refrigeration system unless it has been cleaned and
checked.
Equipment shall be labeled 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.
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 is available. All cylinders to be used are designated for the recovered refrigerant and labeled for that
refrigerant (i.e., special cylinders for the recovery of refrigerant). Cylinders shall be complete with pressure relief
valves and associated shut-off valves in good working order. Empty recovery cylinders are evacuated and, if possible,
cooled before recovery occurs. The recovery equipment shall be in good working order with instructions concerning
the equipment 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 the 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 before returning the compressor to the suppliers. Only electric heating of the compressor body shall be
employed to accelerate this process. When oil is drained from a system, it shall be carried out safely.
