anchors and screws (not included). Mount the range hood on the wall
with the two screws and anchors and tighten.

MAINTENANCE
1. Make sure to unplug the range hood to cut off the power before
maintenance to ensure safety.
2. Clean the inside and outside of the range hood with warm water
containing neutral detergent, then dry with a piece of dry cloth. Do not
scrub with rough materials such as a cleansing ball to avoid damages
to the surface. Put on gloves to avoid injury to your hands when
cleaning the inside. Cleaning can be done one to two times per month.
3. Do not crush the wind wheel when cleaning the inside of the wind track
to avoid deformation. Deformation will increase movement, resulting in
more noise and affect the absorption of oil-smoke.
4. Frequent cleaning of the filter should be performed. First press the
spring on the edge of the filter to dismantle the filter. Dip it into a strong
detergent and brush the surface with a soft brush; then hold the filter
with both hands and move it up and down in the detergent. Rinse with
clean water and allow to air dry. Reinstall the filter. Cleaning can be
done once per week. Do not clean with a combustible detergent such
as banana oil and gasoline.
