Do not operate your VAF series fan with a cut or frayed power cord. Do not unplug your unit by
pulling on its cord. Grasp the plug firmly and pull it out of the wall socket or power receptacle. The
plug has a safety ground pin installed that must not be removed. If the pin is damaged or missing,
have the power cord replaced at once. Visually inspect the power cord before each use. Ignoring
these safety precautions may result in a fire or an electric shock.
Never operate electrical equipment in standing water. There is a shock hazard.
Never drop the unit. Sudden and severe impact may result in damage to internal components.
Your VAF fan should never be operated with the safety grills removed. Personal injury may result.
Drop cloths or other loose fabrics can be drawn against the unit thereby restricting airflow. This
condition may cause the unit to overheat. Keep the air inlet clear of any obstructions.
Save the shipping carton in case your VAF fan must be returned for repair.
This unit should never be serviced or cleaned while it is plugged into a live electrical power source.
WARNING: Ignoring these safety precautions may result in serious personal injury.
