Filter Tank

The filter tank internal components should be visually inspected annually or
whenever back washing does not reduce the pressure of the filter tank to the
starting media gauge pressure. On CL filters, remove the access port on top of the
tank to inspect internal components.
Note: Always use care and follow proper shutdown procedures. Inspect the over
drain assembly for any debris blockage or damage and clean or replace if necessary.
Remove and inspect the media. CL filters have hand access ports located on the side
of the tank for easy media removal under drain inspection. Over a period of time,
foreign matter may become embedded in the media pack that will not back wash.
Contaminated media should be discarded. Unscrew the under drain laterals and
inspect for blockage or damage. Clean or replace if necessary. Refill tank with the
proper amount of new media, following the media loading instructions found in Table
6.
