5.2 Filter/Strainer
A dirty strainer screen and/or fuel filter will slow down the delivery of product. For location see Figure 2-4. If
the underground installation is new, it may be necessary replace the filter and clean the strainer screen two or
three times during the first few days of operation to remove installation debris and pipe sealant. After this, fil-
ter replacement and strainer cleaning should be performed periodically.
NOTE: Replacement fuel filters should be UL recognized. Typically, gasoline fuel filters are rated at 10
Microns and Ethanol fuel filters are rated at 1 micron.
For Ovation model dispensers with an E85 Ethanol grade(s), the recommended filter is Cim-
Tek's Bio-Tek, 1 Micron filter.
WARNING
Before removing the filter and strainer turn the power to the dispenser and submersible pump(s) off and
close the emergency shut-off valves on the dispenser being serviced. Failure to do so may result in a
hazardous condition that can result in serious injury. Loosen strainer cap or spin-on filter slightly and
allow gasoline to drain into a plastic container until pressure is relieved. Return product to the appropri-
ate underground tank.
• The fuel filter is removed by unscrewing it (the same way an oil filter is removed from a car engine).
Place a container under the filter to catch the product and sediment. To install the new filter, first apply a
film of oil to the gasket and hand turn until gasket contacts base, then tighten one half turn. Open the
emergency shut-off valve(s), turn the electrical power ON and check for leaks.
• Remove the strainer for cleaning by unscrewing the filter (or cap) and then pulling out the strainer. Place
a container under the filter or cap to catch the petroleum and sediment. Wash the screen in gasoline and
dislodge lint and other foreign particles with compressed air. Install the clean strainer and a new filter.
Open the emergency shut-off valve(s), turn the electrical power ON and check for leaks.
