IMPORTANT SAFETY INSTRUCTIONS
WARNING
Checks to the area
•Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary
to ensure that the risk of ignition is minimised. For repair to the refrigerating system, the following
precautions shall be complied with prior to conducting work on the system.
Work procedure
•Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or
vapour being present while the work is being performed.
General work area
•All maintenance staff and others working in the local area shall be instructed on the nature of 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.
Checking for presence of refrigerant
•The area shall be checked with an appropriate refrigerant detector prior to 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. non-sparking, adequately sealed or
intrinsically safe.
Presence of fire extinguisher
•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 ignition sources
•No person carrying out work in relation to a refrigeration system which 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, 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.
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.
Checks to the refrigeration 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 are installed.
−The ventilation machinery and outlets are operating adequately and are not obstructed.
−If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence
of refrigerant.
−Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall
be corrected.

8
EN
−Refrigeration 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 suitably protected
against being so corroded.
Checks to electrical devices
•Repair and maintenance to electrical components shall include initial safety checks and component
inspection procedures. If a fault exists that could compromise safety, then no electrical supply shall be
connected to the circuit until it is satisfactorily dealt with. If the fault cannot be corrected immediately
but it is necessary to continue operation, an adequate temporary solution shall be used. This shall be
reported to the owner of the equipment so all parties are advised.
•Initial safety checks shall include:
−Capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking.
−No live electrical components and wiring are exposed while charging, recovering or purging the
system.
−Continuity of earth bonding.
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.
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.
•Other parts may result in the ignition of refrigerant in the atmosphere from a leak
Cabling Check
•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 ageing or continual
vibration from sources such as compressors or fans.
Detection of flammable refrigerants
•Under no circumstances shall potential sources of ignition be used in the searching for or detection of
refrigerant leaks. A halide torch (or any other detector using a naked flame) shall not be used.
Leak detection methods
•The following leak detection methods are deemed acceptable for systems containing flammable
refrigerants.
•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.

9
EN
•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.
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 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 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 ignition sources and there is ventilation available.
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 minimise the amount of refrigerant contained in them.
−Cylinders shall be kept upright.
−Ensure that the refrigeration 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 overfill the refrigeration system. Prior to recharging the system it
shall be pressure tested with OFN. 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.
Decommissioning
•Before carrying out this procedure, it is essential that the technician is completely familiar with the
equipment and all its detail. 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 reclaimed 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 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.

10
EN
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 refrigeration system unless it has been
cleaned and checked.
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
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. Empty 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.

from the base pan if the water level gets high
enough. The water is then picked up by the fan
and expelled through the condenser, making the
air conditioner more efficient.

MAINTENANCE
WARNING
•Before cleaning or performing maintenance,
disconnect the power supply and wait until the
fan stops.
Air Filter
Check the air filter at least twice a month to see
if cleaning is necessary. Trapped particles in the
filter can build up and block the airflow, reducing
cooling capacity and causing an accumulation of
frost on the evaporator.
Cleaning the Air Filter
1 Remove the air filter from the front grille by
pulling the filter forward and then up slightly.
2 Wash the filter using lukewarm water below
40 °C (104 °F).
3 Gently shake the excess water from the filter.
4 Dry the filter in the shade.
5 Insert the filter into the Front grille.
Cleaning the Air Conditioner
•Wipe the front grille and inlet grille with a cloth
dampened in a mild detergent solution.
•Wash the cabinet with mild soap or detergent
and lukewarm water, then polish using liquid
appliance wax.
NOTE
•To ensure continued peak efficiency, the
condenser coils (outside of unit) should be
checked periodically and cleaned if clogged
with soot or dirt from outside air.
•For repair and maintenance, contact a LG
Electronics Customer Information Center.
