4.3. Electrical Connection:
The unit is designed for hard-wired installation. If a plug-in option is desired, a compatible power plug (sold separately) must be installed by a qualified electrician.

6.3. General Cleaning:
Wipe the exterior of the range hood with a soft cloth and mild detergent. Avoid abrasive cleaners or scouring pads that could damage the finish.
