Prior to performing any maintenance work, verify with the chemical hygiene

on the surfaces inside the hood and which cleaners are compatable with the
chemicals used in the hood.

Check sash belts for damage or wear. Replace if frayed. Apply white lithium
grease to the bearings on the sash pulley axles.

Plumbing service fittings can be serviced by removing the hood outside
end panels. If the hood is located against a wall or another hood, removable
gasketed access panels are provided (except on Isotope and Perchloric Acid

on the gasket perimeter until the gasket and panel are free.

For hoods with vapor proof lights, the lights can be accessed from the
hood interior. The globe can be unscrewed from the fixture to expose the
incandescent bulb. The fixture is rated for a maximum bulb size of 150 watts.

For hoods with explosion-proof light, the light can be accessed from the
hood interior. Remove the light panel by unscrewing the bolts at each corner.
