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 HMF2 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. HMF2 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.
