General safety precautions

Warning
Do not remove the power cable while the unit is running or with wet hands. Doing so may result in
electric shocks and fires.
Do not remove the protective grilles or insert hands or objects into the sockets or where the air
comes through.
Do not use any sprays or insecticides on the units. Doing so may result in a fire.
Do not modify the units. Do not attempt to repair the units yourself. Any incorrect or unsuitable
intervention may result in fires, electric shocks or leakage of water or refrigerant.
Caution
Do not pull, stretch or deform the power cable in any way. Doing so may damage the unit or
cause an electric shock.
Don't share the socket with other electric appliances, or use a broken cord. Doing so may cause
electric shocks or fires.
After switching on the air conditioner, do not switch it off for at least 5 minutes. This prevents oil
from returning to the compressor.
Do not use liquid detergents or corrosive products to clean the air conditioner. These may cause
damage or electric shocks.
The air conditioner is only designed for climate control in indoor environments with surface areas and conditions of use ap­
propriate for the installed capacity. Never use it for other purposes.
The air conditioner may only be installed, plumbed in and wired by installers who meet the technical and professional re­
quirements to install and maintain such systems.
This type of indoor unit does not use an electric heater. You cannot install an electric heater or an electric stove at the instal­
lation site.
Periodically check the conditions of installation of the unit. Have the system checked by qualified personnel.
In the event that the power cable is damaged, it must be replaced. Use a type of cable featured in the manual only. The
cable must be replaced by trained, qualified personnel only.
Clean the dust on the plug regularly.
All-pole switch must be installed in the fixed wiring and the distance between contacts should be no less than 3.0 mm.
If your air conditioner is permanently connected to the fixed wiring and have a leakage current that may exceed 10 mA, a
leakage protector must be installed in the fixed wiring.
The power supply circuit should have leakage protector and power switch with a capacity of more than 1.5 times the maxi­
mum current.
If you are not using the air conditioner for an extended period of time, turn off the power switch to save electricity.
If you are not using the air conditioner for an extended period of time, take out the batteries from the remote control.
Use the omnipolar switch or plug to switch off the air conditioner and disconnect power in the event of air conditioner mal­
functioning. If the problem persists, contact your local assistance service.
Do not turn the air conditioner on or off using the power switch or plug.
Do not stand or put things on top of the outdoor unit.
1.3

Electrical wiring

General
Only a qualified installer or qualified service person is allowed to carry out the electrical work of the in­
door and outdoor units. Under no circumstances must this work be done by an unqualified individual
since failure to carry out the work properly may result in electric shocks and/or electrical leaks.
The appliance must be installed in accordance with national wiring regulations. Capacity shortages in the
power supply circuit or an incomplete installation may cause an electric shock or fire.
Precautions
If a power supply cable comes with the appliance and it turns out to be damaged, it must be replaced by
the manufacturer, its after sales service or persons with similar qualifications in order to avoid danger.
48
Danger
Before any wiring work on the electrical circuit, switch off the power supply, check
that no voltage is present and secure the circuit breaker with a circuit breaker lock­
out.
