FOR THE ELECTRICAL EQUIPMENT TO BE DISCONNECTED AND REMOVED, THE OWNER

DISCONNECT AND REMOVE ELECTRICAL DEVICE(S) WHICH WILL INTERFEREWITH THE DEMOLITION AND REMOVAL OF MECHANICAL EQUIPMENT, CONTROLS,AND PIPING AS DESCRIBED IN THE MECHANICAL DEMOLITION PLANS. REMOVEABANDONED CIRCUITRY (WIRING) AND CONDUIT BACK TO PANEL AND DISCARD.CAUTION!!! MAINTAIN EXISTING BUILDING EQUIPMENT AND SYSTEMS THAT ARETO REMAIN.

DISCONNECT AND REMOVE EXISTING ELECTRICAL CONNECTIONS TO THEEXISTING MECHANICAL AND/OR PLUMBING EQUIPMENT THAT IS TO BEREMOVED, AS INDICATED. ALL DISCONNECTS AND POWER DEVICES ARE TO BEREMOVED AND DISCARDED. REMOVE EXISTING CIRCUITRY (WIRING) ANDCONDUIT BACK TO PANEL OR SOURCE AND DISCARD. ALL UNUSED ABOVEGROUND CIRCUITRY (WIRING) AND CONDUIT ON THE EXTERIOR OF THEBUILDING SHALL BE DISCONNECTED AND REMOVED. EXISTING UNDERGROUNDCONDUIT SHALL BE CUT BELOW GRADE AND ABANDONED. ALL THRU-WALLPENETRATIONS SHALL BE FILLED WITH EXTERIOR RATED SILICONE SEALANT,COLOR TO MATCH EXISTING INTERIOR/EXTERIOR WALLS. PROVIDE BLANKCOVER PLATES FOR EMPTY GANG BOXES. COORDINATE ALL DISCONNECTIONSWITH THE MECHANICAL CONTRACTOR.
