Attaching the Front Panel
1. After all connections have been completed, inspect and clean the machined flange joint surfaces of
both the cover and the box. Surfaces must be smooth, free of nicks, scratches, dirt or any foreign
particle build-up that would prevent a proper seal. Surfaces must seat fully against each other to
provide a proper explosion-proof joint. Clean surfaces by wiping with a clean lint-free cloth.
2. Apply a light coat of Killark “LUBG” lubricant to flange surfaces and close the cover. Install and
tighten all cover bolts to 30 ft-lbs. Make certain no cover bolts are omitted. Use only those bolts
supplied with the enclosure.
3. Reapply power to the station.
