L "bird" cage secured to top of influent air pipe <br /> M Record hours of operation by checking cumulative hour meter on blower or at <br /> electrical panel <br /> N While the blower is running, verify that air is being pulled in through the air <br /> intake pipe and through groundwater This is done by measuring air flow through <br />' the fresh air intake If neither air flow, vibration or bubbling is heard, re-check <br /> parameters H B) through J) and parameters in III If problems persist, contact EA <br /> and IEG® If air is passing through the water, vibration of the air intake pipe will <br />' be observed, and a vigorous bubbling action will be heard by placing the ear <br /> against the air intake pipe <br /> O Verify proper functioning of support pump by stopping and starting pump Place <br /> the ear to the intake pipe and this will allow you to hear when the pump is turned <br /> on and off <br />' 3. Inspection of System: <br /> The UVB system will be removed for inspection a minimum of once every six months for <br />' the firstear <br /> Y � <br /> A After UVB system is removed, it will be checked for iron and scaling build-up, <br /> any build-up or clogging of the screen holes should be removed Remove iron <br /> and scaling build-up on UVB component parts by pressure washing stripping <br /> reactor, and reaming out sieve plate holes, if there is a significant reduction in the <br /> operating parameters of the system <br /> B When all the parts of the UVB system are removed, the packer lines and cables <br /> will be checked for twisting and tightness, and corrections made if necessary <br />' (floating UVB system only) <br /> C When a fixed or floating UVB system is removed, the well will be sounded and <br />' checked for sediment build-up, and any sediment covering more than 15 percent <br /> of the Iower screen will be removed Contact EA and IEG' for best method to <br /> remove sediment <br /> 1 <br />' WP61 73942 WP1096 TX 2 2 <br />
