WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK,DO NOT USE THIS
FAN WITH ANY SOLID-STATE SPEED CONTROL DEVICE
Check voltage corresponds to the one indicated on the rating plate/label plate fixed inside the hood.
Check that the domestic power supply guarantees adequate grounding.
Do not connect the hood to exhaust ducts carrying combustion fumes(boilers,fireplaces,etc.)
If the hood is used in conjunction with non-electrical appliances(e.g.gas burning appliances),a sufficient degree of aeration must be guaranteed in the room in order to prevent the backflow of exhaust gas.The kitchen must have an opening directly with the open air in order to guarantee the entry of clean air.
The minimum distance is 30 inches from the range hood to a gas cooktop,and is 25 inches to an electric cooktop.If the installation instructions for gas cooktop specify a greater distance,this must be taken into account.
In certain circumstances electrical appliances may be a danger hazard.
Do not check the status of the filters while the range hood is operating.
Do not touch the light bulbs during or right after appliance in use.
Do not operate or disconnect the appliance with wet hands.
Avoid free flame,as it is damaging for the filters and a fire hazard.
