Inspect and clean the machined flange flame joint surfaces of both the cover and box.
Surfaces must be smooth, free of nicks, scratches, dirt, or any foreign particle build-up that may
prevent a proper seal. Surfaces must seat fully against each other to provide a proper explosion-proof
joint.
2.
Clean the surfaces by wiping them with a clean lint-free cloth.
3.
Install all 12 cover bolts.
Use only the bolts supplied with the enclosure. Do not omit any bolts.
4.
Torque the cover bolts to 17 ft∙lb (23 N∙m).
