ti � <br /> 3 � P a g e - FloGard° Perk Filter System O&M Manual <br /> _ _ _ .. . .. __.._ _ _ _ _ <br /> Maintenance Overview for FloGard�Perk Filter Systems <br /> State and Local regulations require that stormwater management systems be maintained and serviced <br /> on a recurring basis. The purpose of maintaining a clean and obstruction free Perk Filter system is to <br /> ensure the system performs the intended function of the primary design.Trash and debris,floatables, <br /> gross pollutants and sediment can build up in any stormwater system.This can cause the system to <br /> function improperly by impeding flow in and out of the system and reducing the operating efficiency of the <br /> media filters. Downstream and upstream, areas could run the risk of flooding and deleterious <br /> environmental impact. <br /> Recommended Frequency of Service <br /> It is recommended that FloGardO Perk Filter systems be serviced on a regularly occurring basis. <br /> Ultimately the frequency depends on the amount of runoff, pollutant loading, and interference from trash, <br /> debris and gross pollutants as well as proper maintenance of upstream pretreatment devices. However, <br /> it is recommended that each installation be inspected in accordance with the following guidelines: <br /> Level 1 Inspection Service—Six(6) months after unit is placed into service, or six (6) months after a <br /> Level 2 or Level 3 inspection. <br /> Leve12 Inspection Service- Six (6) months after a Level 2 inspection or twelve (12) months after a <br /> Level 3 service. <br /> Level 3 Service—As determined by findings from Level 2 inspection service reports indicating a media <br /> filter change or system repairs are required to maintain the operating efficiency of the system. <br /> Service Procedures <br /> Inlet Bay <br /> 1. The inlet manhole cover(s) and or grate(s)shall be removed and placed to one side. <br /> 2. For systems with a FloGard Plus Catch Basin Insert,the insert will be cleaned in accordance with <br /> the general specifications for maintenance of those devices. After cleaning the filter shall be <br /> removed and set aside. <br /> 3. Any debris will be removed from the inlet bay(s) and disposed of in accordance with local <br /> regulations. <br /> 4. Check and clean the area behind and under the inlet weir/bypass assembly. Remove assembly <br /> as necessary to conduct inspection. <br /> 5. Check drain down assembly and clean if necessary. <br /> 6. Re-install catch basin insert filter. <br /> 7. Re-install grate or manhole access cover. <br /> Cartridge Bay <br /> 1. Remove and place to one side the manhole access covers above the cartridge bay. <br /> 2. A Level 1 inspection service shall consist of a visual inspection from the surface level. Observe <br /> and note the condition of the cartridge bay and the cartridges, measure sediment level, if any, <br /> and note on maintenance record. Physical entry is not required unless the depth prevents the <br /> entire cartridge bay area from being observed. <br /> KriStar Enterprises,Inc. <br /> 360 Sutton Place <br /> Santa Rosa,CA 95407 <br /> (800)579-8819 <br /> www.kristar.com <br />
