Electrical safety

Before connecting the appliance to the mains for the ﬁrst time, make sure that the mains voltage indicated on the type plate of the appliance corresponds to the mains voltage in your home.
The electrical appliance is designed to be supplied from the mains 1/N/PE ~ 230 V 50 Hz.
The electrical safety of the appliance is only guaranteed if it is connected correctly to the mains.
Electrical equipment of protection class I is equipped with protection against electric shock by means of protective earthing of inanimate parts, which can become dangerously alive in the event of equipment failure. Always connect such devices to properly installed power outlets that are equipped with a protective earth and have a properly connected protective earth conductor.
These are all electrical devices equipped with a three-wire power supply.
Electrical equipment of protection class II is equipped with protection against electric shock by double insulation or reinforced insulation of dangerous live electrical parts. Protection class II equipment must not be equipped with means of connection protective earthing. These are all electrical devices equipped with a two-wire power supply.
Electrical protection class III devices are devices that are powered by a source of low safe voltage (battery or accumulator) and do not pose any danger to the user in the event of an electric shock.
To ensure increased safety against the risk of electric shock when using electrical appliances by laymen, it is recommended to install a residual current device (RCD) in the power supply circuit for sockets with a rated current not exceeding 20 A with a rated tripping current not exceeding 30 mA. Consult a qualiﬁed electrician to ensure the safety and correctness of the electrical installation.
Use only the power cord with the plug (mains lead) that came with the device and is compatible with the mains socket. Use of another cable may result in ﬁre or electric shock.
Always connect the appliance to an easily accessible mains socket. In the event of an operating fault, the appliance must be switched off and disconnected from the mains as soon as possible.
The power cord and mains plug must always remain easily accessible for safe disconnection of the electrical appliance from the mains.
Do not unplug the power cord by pulling on the cord. To disconnect, unplug the power cord.
If you use an extension cord, make sure that the total ampere rating of all devices plugged into the extension cord does not exceed the extension cord‘s ampere rating.
If you must use an extension cord or power supply, make sure that the extension cord or power supply is connected to an electrical outlet and not to another extension cord or power supply. The extension cord or power strip must be rated for grounded electrical plugs and plugged into a properly grounded electrical outlet.
The plug of the appliance‘s power cord must be compatible with the mains socket. Never use any adapters or modify the outlet in any other way. Do not use unsuitable and damaged sockets!
To prevent electric shock, plug the device‘s power cords into properly grounded electrical outlets. If your device has a 3-pin power cord, do not use adapters that do not have a grounding element or remove the grounding element from the plug or adapter.
Do not bend, squeeze or otherwise expose the appliance ‚s power cord /mains cord to mechanical stress or external heat sources. Damage to the power cord may result in electric shock.
If the power cord is damaged, disconnect the appliance from the mains and do not continue to use it.
If the supply cord/plug is damaged, it must be replaced by the manufacturer, its service agent or similarly qualiﬁed persons in order to avoid a hazard.
Regularly check and keep the electrical appliance as well as the power cord and mains socket. Unplug the power cord regularly and clean as needed. Contamination by dust or other substances can cause damage to the insulation condition and subsequent ﬁre.

Personal safety

This appliance is intended for use and operation by persons without electrical qualiﬁcation – by laymen, according to the instructions provided by the manufacturer.
The operation of the device includes activities such as switching the device on and off, user manipulation and setting of operating parameters, visual or auditory control of the device and user cleaning and maintenance.
This appliance may be used by children from the age of 8 and persons with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, if they have been given supervision or instruction concerning use of the appliance safely and understand the dangers involved.
Children must not play with the appliance.
Cleaning and maintenance by users must not be performed by children without supervision.
Always keep the appliance out of the reach of children during use and operation. Remember that the appliance can also be downloaded with a freely accessible mains cord.
Always take extra care when operating the appliance! Do not use an electrical appliance if you are excessively tired, under the inﬂuence of drugs or drugs that reduce attention and concentration.
Careless handling can lead to serious injuries.

Cleaning, maintenance and repairs

Carry out routine user cleaning and maintenance of the electrical appliance only as recommended. Do not use solvents or harsh cleaning items for cleaning. Dirt and visible stains from ﬁnger contact, resp. hands can be cleaned using cleaning detergents specially designed for cleaning household appliances.
Always disconnect the appliance from the mains when you are not using it, cleaning it or when the appliance has malfunctioned.
Protect electrical appliances that are cleaned after use and are not intended to be completely or partially immersed in water or any other liquid against the effects of dripping and / or splashing water and against immersion.
Electrical household appliances, like all other technical equipment, are subject to the effects of the surrounding operating environment and natural wear. Due to the fact that there is no legal framework for regular maintenance used in household appliances, the manufacturer recommends that the user have the appliance inspected and professionally cleaned at least once a year by a special service.
By doing so, it is possible to maintain safety, operational reliability and increase the service life of the equipment.
Do not disassemble the electrical appliance! The appliance operates with dangerous voltage. Therefore, always switch off the appliance and disconnect it from the mains during user maintenance. In the event of a fault, have it repaired by an authorized service center.
Before you call for service:
- Switch the appliance off and on to make sure that the fault reappears.
- If the appliance malfunctions persist after the above operations, call the nearest special service.
Never repair the electrical appliance yourself!
Unauthorized, unqualiﬁed and unprofessional intervention in the electrical appliance may result in electric shock or other serious injury.
Only entrust warranty and post-warranty repairs of the electrical appliance to a qualiﬁed technician(*).

(*) Qualiﬁed specialist: the sales department of the manufacturer or importer or a person who is qualiﬁed and authorized to carry out this type of activity with the ability to avoid all hazards.

Special safety instructions. Read carefully!
