All wiring for the fume hood SHOULD be performed by a
licensed electrician and conform to all local codes. In most
cases, the hood will require the use of shielded conduit to
protect the wiring into the hood. The grounding connection
shall not be made to the terminal box cover.
The fluorescent light has been mounted outside the top liner panel and is sealed
from vapors inside the hood structure. To change the fluorescent light bulbs in
your hood, you must first remove the front panel from the hood. Next remove the
knock out plugs holding the light fixture in place. Lift fixture up and replace any
defective bulbs. Reverse order to reassemble.
