• If the supply cord is damaged, it must be replaced by the manufacturer, its service agent, or similarly
qualified persons in order to avoid a hazard.
• The appliance should be disconnected from its power source during service.
• Always operate the unit from a power source with the same voltage, frequency, and rating as
indicated on the product identification plate.
• Always use a grounded power outlet.
• Unplug the power cord when cleaning or when the appliance is not in use.
• Do not operate the appliance with wet hands. Prevent water from spilling onto the unit.
• Do not immerse or expose the appliance to rain, moisture, or any other liquid.
• Do not leave the appliance running unattended. Do not tilt or turn over the unit.
• Do not unplug the appliance while it is operating.
• Do not unplug the appliance by pulling on the power cord.
• Do not use an extension cord or an adapter plug.
• Do not place objects on the unit.
• Do not climb or sit on the unit.
• Do not insert fingers or other objects into the air outlet.
• Do not touch the air inlet or the aluminum fins of the unit.
• Do not operate the unit if it has been dropped, damaged, or shows signs of product malfunction.
• Do not clean the appliance with any chemicals.
• Ensure that the unit is kept far away from fire, inflammable, or explosive objects.
• The unit should be installed in compliance with national wiring regulations.
• Only use the recommended methods for defrosting and cleaning the appliance, and avoid any other
means.
• Store the appliance in a room without any continuously operating sources, such as open flames,
operating gas appliances, or operating electric heaters.
• Store the appliance in a way that prevents any mechanical damage.
• Do not puncture or burn the appliance, even after use.
• Please note that refrigerants may not have an odor.
• Protect the pipe-work from physical damage and avoid installing it in an unventilated space smaller
than 4 m².
• Ensure compliance with national gas regulations.
• Keep all required ventilation openings clear and free from obstructions.
• Store the appliance in a well-ventilated area that meets the specified room area requirements for
operation.
FOR YOUR SAFETY - WARNING
Any person involved in working on or accessing a refrigerant circuit must possess
a valid certicate from an industry-accredited assessment authority. This
certicate should conrm their competence in handling refrigerants safely, in
accordance with an industry-recognized assessment specication.
FOR YOUR SAFETY - WARNING
Servicing should only be performed as recommended by the equipment
manufacturer. Maintenance and repair tasks that require the help of other
qualied personnel should be carried out under the supervision of an individual
who is competent in handling ammable refrigerants.
2.2 SAFETY PRECAUTIONS DURING SERVICING
Please adhere to the following warnings and precautions when servicing an appliance with R32:
2.2.1 Area Checks
Before starting work on systems containing flammable refrigerants, safety checks must be conducted
to minimize the risk of ignition. Prior to performing any work on the refrigerating system, the following
precautions should be taken:
2.2.2 Work Procedure
All work should be carried out following a controlled procedure to minimize the presence of flammable
gases or vapors.
2.2.3 General Work Area
All maintenance staff and individuals working in the vicinity should be informed about the nature of the
work being carried out. It is important to avoid working in confined spaces. The work area should be
cordoned off, and measures should be taken to ensure the safety of the area by controlling flammable
materials.
2.2.4 Refrigerant Presence Check
An appropriate refrigerant detector should be used to check the area before and during work to identify
potentially flammable atmospheres. Make sure that the leak detection equipment being used is suitable
for flammable refrigerants, meaning it should not produce sparks, be adequately sealed, or be
intrinsically safe.
2.2.5 Presence Of Fire Extinguisher
If any hot work is to be performed on the refrigeration equipment or any associated parts, appropriate
fire extinguishing equipment must be readily available. It is advised to have a dry powder or CO2 fire
extinguisher positioned near the charging area.
2.2.6 Avoiding Ignition Sources
Any individual conducting work related to a refrigeration system that involves exposing pipes containing
or having contained flammable refrigerants must not use any sources of ignition that may pose a risk of
fire or explosion. All potential ignition sources, including cigarette smoking, should be kept at a
sufficient distance from the installation, repair, removal, and disposal sites where flammable
refrigerants may be released into the surrounding space. Prior to commencing work, the equipment
area should be inspected to ensure there are no flammable hazards or ignition risks. "No Smoking" signs
must be prominently displayed.
2.2.7 Ventilated Area
Before breaking into the system or performing any hot work, ensure that the area is either open or
adequately ventilated. Sufficient ventilation should be maintained throughout the duration of the work
to safely disperse any released refrigerant, preferably by expelling it externally into the atmosphere.
2.2.8 Checks On Refrigeration Equipment
When replacing electrical components, ensure that they are suitable for the intended purpose and meet
the correct specifications. Always follow the manufacturer's maintenance and service guidelines. If
there are any uncertainties, consult the manufacturer's technical department for assistance.
