4.) Remove the cap from the nipple on the top of the interceptor and connect the
draw-off hose. Position the hose to drain into a suitable waste receptacle.
5.) Run hot water through the interceptor at a rate of 1.5-2.5 gallons per minute.
6.) The interceptor will fill, and then force the liquefied FOG out through the draw-off
hose. When clear water begins to discharge, the interceptor is clean.
7.) Disconnect the draw-off hose and replace the nipple cap.
8.) Re-open the shut-off valve and fill the interceptor with clean water. The intercep-
tor is now ready for normal use.
9.) Dispose of the collected FOG in a manner suitable to local authorities.
The interceptor should be opened for manual cleaning and inspection periodically,
or if the semi-automatic cleaning process becomes difficult. To clean the intercep-
tor, remove the nipple cap and bolts securing the top cover. Remove the cover and
grease accumulating cone. Evacuate the interceptor completely and remove any
accumulated FOG and debris from the interior.
Prior to replacing the cover, make sure the inlet, outlet and internal air relief are free
of obstructions, and inspect the cover gasket for damage or potential leak points.
Fill the interceptor with clean water prior to resuming use.
Extensions
An interceptor extension is used to effectively lower the level of an interceptor's
inlet and outlet, enabling piping connections further below grade. Extensions are
commonly required for recessed interceptor installation to accommodate the fall in
long piping runs, or ensure an interceptor's static water line remains below the local
frost line.
