DATE 18 BAYFILTER MAINTENANCE THE BAYFILTER SYSTEM REQUIRES PERIODIC MAINTENANCE TO CONTINUE OPERATING AT ITS PEAK EFFICIENCY DESIGN. THE MAINTENANCE PROCESS COMPRISES THE REMOVAL AND REPLACEMENT OF EACH BAYFILTER CARTRIDGE AND THE CLEANING OF THE VAULT OR MANHOLE WITH A VACUUM TRUCK. FOR BEST RESULTS, BAYFILTER MAINTENANCE SHOULD BE PERFORMED BY A CERTIFIED MAINTENANCE CONTRACTOR. A QUICK CALL TO AN ADS ENGINEER OR CUSTOMER SERVICE REPRESENTATIVE WILL PROVIDE YOU WITH A LIST OF RELIABLE CONTRACTORS IN YOUR AREA. WHEN BAYFILTER IS INITIALLY INSTALLED, WE RECOMMEND THAT AN INSPECTION BE PERFORMED ON THE SYSTEM IN THE FIRST SIX (6) MONTHS. AFTER THAT, THE INSPECTION CYCLE TYPICALLY FALLS INTO A BIANNUAL PATTERN GIVEN NORMAL STORM OCCURRENCE AND ACTUAL SOLIDS LOADS. WHEN BAYFILTER EXHIBITS FLOWS BELOW DESIGN LEVELS, THE SYSTEM SHOULD BE INSPECTEDAND MAINTAINED AS SOON AS PRACTICAL. REPLACING A BAYFILTER CARTRIDGE SHOULD BE CONSIDERED AT OR ABOVE THE LEVEL OF THE MANIFOLD. MAINTENANCE PROCEDURES 1. REMOVE THE MANHOLE COVERS AND OPEN ALL ACCESS HATCHES. 2. BEFORE ENTERING THE SYSTEM MAKE SURE THE AIR IS SAFE PER OSHA STANDARDS OR USE A BREATHING APPARATUS. USE LOW 02, HIGH CO, OR OTHER APPLICABLE WARNING DEVICES PER REGULATORY REQUIREMENTS. 3. USING A VACUUM TRUCK, REMOVE ANY LIQUID AND SEDIMENTS THAT CAN BE REMOVED PRIOR TO ENTRY. 4. USING A SMALL LIFT OR THE BOOM OF THE VACUUM TRUCK, REMOVE THE USED CARTRIDGES BY LIFTING THEM OUT. 5. ANY CARTRIDGES THAT CANNOT BE READILY LIFTED CAN BE EASILY SLID ALONG THE FLOOR TO A LOCATION THEY CAN BE LIFTED VIA A BOOM LIFT. 6. WHEN ALL THE CARTRIDGES HAVE BEEN REMOVED, IT IS NOW PRACTICAL TO REMOVE THE BALANCE OF THE SOLIDS AND WATER. LOOSEN THE STAINLESS CLAMPS ON THE FERNCO COUPLINGS FOR THE MANIFOLD AND REMOVE THE DRAINPIPES AS WELL. CAREFULLY CAP THE MANIFOLD AND THE FERNCO'S AND RINSE THE FLOOR WASHING AWAY THE BALANCE OF ANY REMAINING COLLECTED SOLIDS. 7. CLEAN THE MANIFOLD PIPES, INSPECT, AND REINSTALL. 8. INSTALLTHE EXCHANGE CARTRIDGES AND CLOSE ALL COVERS. 9. THE USED CARTRIDGES MUST BE SENT BACKTO ADS FOR EXCHANGE/RECYCLING AND CREDIT ON UNDAMAGED UNITS. BAYFILTER INSTALLATION NOTES 1. CONTACT UTILITY LOCATOR TO MARKANY NEARBY UNDERGROUND UTILITIES AND MAKE SURE IT IS SAFE TO EXCAVATE. 2. REFERENCE THE SITE PLAN AND STAKE OUT THE LOCATION OFTHE BAYFILTER VAULT. 3. EXCAVATE THE HOLE, PROVIDING ANY SHEETING AND SHORING NECESSARY TO COMPLY WITH ALL FEDERAL, STATE AND LOCAL SAFETY REGULATIONS. 4. LEVELTHE SUB -GRADE TO THE PROPER ELEVATION. VERIFY THE ELEVATION AGAINST THE MANHOLE DIMENSIONS, THE INVERT ELEVATIONS, AND THE SITE PLANS. ADJUST THE BASE AGGREGATE, IF NECESSARY. 5. HAVETHE SOIL BEARING CAPACITY VERIFIED BYA LICENSED/ENGINEER FORTHE REQUIRED LOAD BEARING CAPACITY. ON SOLID SUB -GRADE, SETTHE FIRSTSECTION OFTHE BAYFILTER PRE--CASTVAULT. 6. CHECK THE LEVELAND ELEVATION OFTHE FIRST SECTION TO ENSURE IT IS CORRECT BEFOREADDING ANY RISER SECTIONS. 7. IFADDITIONAL SECTION(S) ARE REQUIRED, ADD A WATERTIGHT SEALTO THE FIRST SECTION OFTHE BAYFILTER VAULT. SETADDITIONAL SECTION(S) OF THE VAULT, ADDING A WATERTIGHT SEALTO EACH JOINT. 8. INSTALLTHE PVC OUTLET MANIFOLD. 9. INSTALLTHE PVC OUTLET PIPE IN BAYFILTER VAULT. 10. INSTALLTHE INLET PIPETO THE BAYFILTER VAULT. 11. AFTER THE SITE IS STABILIZED, REMOVE ANY ACCUMULATED SEDIMENT OR DEBRIS FROM THE VAULT AND INSTALLTHE FLOW DISKS, DRAINDOWN MODULES (IFAPPLICABLE), AND THE BAYFILTER CARTRIDGES. 12. PLACE FULL SET OF HOLD DOWN BARS AND BRACKETS INTO PLACE.
