The term "device" or "product" in the warnings and in the description of the manual refers to:
Air dehumidifier.
2.1. Electrical safety
a) The plug of this device must fit into the outlet. Do not modify the plug in any way. Original plugs and matching outlets reduce the risk of electric shock.
b) Avoid touching grounded parts, such as pipes, heaters, ovens, and refrigerators. There is an increased risk of electric shock if your body is grounded and touches the device while exposed to direct rain, wet pavement, or while working in a damp environment. If water enters the device, there is an increased risk of damage to the unit and electric shock.
c) Do not touch the device with wet or damp hands.
d) Do not use the cord in an unintended manner. Never use it to carry the device or to pull the plug out of the socket. Keep the cord away from heat sources, oil, sharp edges or moving parts. Damaged or tangled cords increase the risk of electric shock.
e) If you cannot avoid using the product in a wet environment, use a residual current device (RCD) to connect it to electrical mains. Using an RCD reduces the risk of electric shock.
f) Do not use the device if the power cord is damaged or shows signs of wear. A damaged power cord should be replaced by a qualified electrician or the manufacturer's service department.
g) To avoid electric shock, do not immerse the cable, plug, or the device itself in water or other liquid. Do not use the appliance on wet surfaces.
h) CAUTION – DANGER TO LIFE! When cleaning or using the appliance, never immerse it in water or other liquids.
i) Use only power sources that are grounded.

a) Keep the work area tidy and well lit. Disorder or poor lighting can lead to accidents. Be foresighted, watch what you are doing and use common sense when using the unit.
b) Do not use the device in a potentially explosive atmosphere, for example in the presence of flammable liquids, gases or dust. The unit produces sparks that can ignite dust or fumes.
c) If you find any damage or irregularities in the operation of the unit, immediately turn it off and report it to an authorized person.
d) If you have any doubts as to whether the product is working properly or if it is damaged, contact the manufacturer's service department.
e) Repairs to the device may only be carried out by the manufacturer's service. Do not attempt to repair the product on your own!
