NSTALLATION How to Seal Killark Box Conduit with Fiber and ® Sealing Compound to Help Protect Against Explosions (Explosion-Proof Units Only): The purpose of the procedure that follows is to build fiber rope dams on the left and right hubs of the horizontal conduit. The fiber rope damns will surround conduit wiring that is housed inside the horizontal conduit. - Page 22 NSTALLATION Figure 2: Horizontal Conduit, Cutaway Wiring Left Hub Right Hub • Insert fiber rope material down into horizontal conduit opening.

Immediately wipe off any spilled sealing compound. • Screw conduit domed-cover back onto conduit opening. NOTE: INITIAL SETUP OF SEALING COMPOUND WILL OCCUR IN APPROXIMATELY 30 MINUTES HOW- EVER, THE SEALING COMPOUND REQUIRES A MINIMUM OF 8 HOURS ABOVE 32ºF TO DEVELOP SUFFICIENT STRENGTH TO WITHSTAND EXPLOSIONS.
