IF YOU HAVE ANY QUESTIONS, PLEASE CALL US IMMEDI ATELY AT {561) 775 9303. THE BAFFLE PANELS ARE GENERALLY INSTALLED IN A COUNTERCLOCKWISE MANNER TO THE INSIDE SURFACE OF THE TANK WALL ALONG THE CIRCUMFERENCE AS IF LOOKING OUTWARD FROM THE CENTER. 1) EXAMINE THE PROPOSED LOCATION ALONG THE ENTIRE PERIMETER OF THE TANK AT THE PROPER ELEVATION FOR ANY INTERFERENCE OR OBSTRUCTION. 2) IE NO OBSTRUCTION EX I STS, BEGIN THE INSTALLATION BY MOUNTING THE FIRST BAFFLE PANEL AT THE PROPER ELEVATION RANDOMLY AT SOME POINT ALONG THE PERIMETER OF THE TANK WALL. USE THE FACTORY MOUNTING HOLES IN THE PANEL AS A GUIDE TO MARK THE WALL PRIOR TO DRILLING THE ANCHOR MOUNTING HOLES. REMOVE THE PANEL AND DRILL THE WALL ANCHOR HOLES {NEVER USE THE FACTORY HOLES AS A DR I LLING TEMPLATE) . INSERT THE APPROPRIATE ANCHORS INTO THE HOLES, REPLACE THE PANEL AND SECURE IT TO THE WALL WITH THE HARDWARE AS SHOWN IN THE INSTALLATION DETAIL. MOVE TO THE LEFT ANO MOUNT THE NEXT PANEL SIMILAR TO THE FIRST. IN ADDITION TO THE MOUNTING HOLES, ALSO MARK THE LAP HOLES ON THE RECESS OF THE INTEGRAL BRACKET OF THE FIRST PANEL MOUNTED USING THE FACTORY HOLES IN THE RIGHT SIDE OF THE SECOND PANEL AS A GUIDE. CONTINUE INSTALLING PANELS FROM RIGHT TO LEFT USING THE SAME STEPS UNTIL YOU REACH THE OPPOSITE SIDE OF THE FIRST PANEL INSTALLED. ACCURATELY MEASURE ANO THEN FIELD CUT THE LAST BAFFLE PANEL TO FIT THE REMAINING SPACE AND INSTALL. 3) IF AN OBSTRUCTION DOES EXI ST LIKE THE EFFLUENT BOX OR SCUM PIPE, BEGIN BY MOUNTING THE FREE END BRACKET AT THE DESIRED ELEVATION TO THE LEFT SIDE OF THE OBSTRUCTION. INSTALL THE FIRST BAFFLE PANEL TO THE LEFT SIDE OF THE FREE END BRACKET USING THE SAME METHOD AS IN STEP-1 ABOVE. LAP THE RIGHT SIDE OF THE PANEL ON TOP OF THE FREE END BRACKET. MARK THE LAP HOLES ON THE FREE END BRACKET USING THE FACTORY HOLES IN THE RIGHT SIDE OF THE PANEL AS A GUIDE. AGA IN, R EMOVE THE PANEL BEFORE DRILLING. CONTINUE INSTALLING PANELS FROM RIGHT TO LEFT UNTIL YOU REACH THE OPPOSITE SIDE OF THE OBSTRUCTION. ACCURATELY MEASURE AND THEN FIELD CUT THE LAST BAFFLE PANEL TO FIT THE REMAINING SPACE AND INSTALL.
