2. Safety Precautions

It is imperative to read and understand all safety instructions before installing, operating, or maintaining the unit. Failure to comply with these instructions may result in electric shock, fire, serious injury, or property damage.

2.1. General Safety Warnings

• DANGER: Before touching electrical terminals, turn off the power switch.
• DANGER: When removing service panels, there is a risk of accidentally touching live components.
• DANGER: During installation or service operations, never leave the unit unattended after removing service panels.
• DANGER: Do not touch water lines during or immediately after use, as high temperatures may cause burns. Wait for water lines to return to normal temperature or wear protective gloves.
• DANGER: Never touch switches with wet hands. Contact between wet hands and switches can cause electric shock.
• DANGER: Before touching electrical components, turn off all powered parts of the unit.
• WARNING: Tear and discard plastic packaging bags to prevent children from playing with them, as plastic bags can pose a suffocation risk.
• WARNING: Securely install packaging materials that may cause injury, such as nails or other metal or wood parts.
• WARNING: Installation operations must be performed by dealer personnel or other qualified persons in compliance with this manual's instructions. Do not install the unit yourself. Incorrect installation can lead to water leaks, electric shock, or fire.
• WARNING: For installation, use only specified accessories and components. Failure to use specified components can cause water leaks, electric shock, fire, or the unit to fall from its mounting position.
• WARNING: Install the unit on a support that can bear its weight. Incorrect installation can cause injuries due to the appliance falling.
• WARNING: Electrical connections must be performed by qualified personnel, in compliance with current laws and regulations and this manual's instructions, using a separate circuit. Insufficient power supply or incorrect electrical connections can cause electric shock or fire.
• WARNING: Install an automatic circuit breaker with ground fault protection in accordance with current laws and regulations. Failure to observe this measure can cause electric shock or fire.
• WARNING: Check the safety of all electrical cables. Use specified cable types and protect wires and connection terminals from water and other external agents. Incomplete connections or fittings can create fire hazards.
• WARNING: For electrical connection, arrange wires so that the front panel can be securely fastened. Failure to apply the front panel can cause terminal overheating or create risks of electric shock or fire.
• WARNING: At the end of installation operations, check for refrigerant leaks.
• WARNING: Never directly touch refrigerant leaks, as contact can cause severe cold injuries. Do not touch refrigerant pipes during or immediately after use as they may be very hot or cold. Wait for pipes to return to normal temperature or wear protective gloves.
• WARNING: Do not touch internal components (pump, auxiliary heater, etc.) during or immediately after use. Contact with internal components can cause burns. Wait for components to return to normal temperature or wear protective gloves.

2.2. Important Considerations

• Connect the unit to ground. Ground resistance must comply with current laws and regulations.
• Do not connect the ground wire to gas or water pipes, lightning rods, or telephone system ground wires. Incorrect grounding can cause electric shock.
• Gas pipes: A gas leak can cause fire or explosion risks.
• Water lines: Rigid vinyl pipes do not create an effective ground.
• Lightning rods or telephone system ground wires: A lightning strike could cause an abnormal rise in electrical threshold.
• Install the power cable at least 1 meter (3 feet) away from televisions or radio devices to avoid interference or disturbances.
• Do not wash the unit. Humidity can cause electric shock or fire risks. The appliance must be installed in accordance with national electrical connection regulations. If the power cable is damaged, it must be replaced by the manufacturer, its representative, or other qualified persons to avoid dangerous situations.
• Do not install the unit in the following locations:
  • Environments exposed to mineral oil mists, sprays, or vapors. Plastic components may deteriorate and detach, or water leaks may occur.
  • Environments where corrosive gases (like sulfuric acid gas) are produced. Corrosion of copper pipes or soldered components could cause refrigerant leaks.
  • Environments with machinery emitting electromagnetic waves. Electromagnetic waves can disturb the unit's control system, causing the unit to fall from its mounting position.
  • Environments exposed to flammable gas leaks, with suspensions of carbon fibers or flammable dust, or where volatile flammable materials like gasoline or paint thinners are handled. These types of gases can create fire hazards.
  • Environments where the air is strongly saline, e.g., near coastlines.
  • Environments exposed to marked voltage fluctuations, such as factories.
  • Vehicles or ships.
  • Environments with acidic or alkaline vapors.
• The appliance is suitable for use by children aged 8 and above and persons with reduced physical, sensory, or mental capabilities or lack of experience/knowledge, provided they are adequately supervised or have received instructions on safe use and understand related hazards. Children must not play with the unit. Cleaning and maintenance operations must not be performed by unsupervised children.
• Supervise children to ensure they do not play with the appliance. If the power cable is damaged, it must be replaced by the manufacturer, its representative, or a qualified person.
• DISPOSAL: Do not dispose of the product as unsorted waste. The used unit must be disposed of and collected separately as differentiated waste. Do not dispose of electrical appliances with household waste; use your municipality's collection points. Contact the local authority for information on the differentiated collection system. Appliances disposed of in public landfills can release hazardous substances that, if absorbed by soil and groundwater, can enter the food chain with harmful consequences for health.
• Electrical connections must be performed by professional technicians in accordance with national regulations and the electrical diagram. A multipolar switch with a contact distance of at least 3 mm at all points and a residual current device (RCD) with a nominal voltage greater than 30 mA must be integrated into the fixed wiring in compliance with current electrical connection regulations.
