Media - Over time, excessive amounts of mineral deposits will begin to buildup
on the media. Annually, scale and dirt should be washed off the entering sur-
face of the media. Remove the pad retainers and screen. (See Steps 1-3 and 6-
8 of Media Replacement Instructions.) Clean the media using a garden hose,
mild soap, and a soft bristled brush. When the media becomes too clogged
with mineral deposits and dirt that it cannot be cleaned, the pads should be
replaced. The average pad life is approximately three cooling seasons.
Select the correct replacement part numbers and order media pads from your
Distributor. Follow the instructions below and remove and replace pads as
shown in FIGURE 6.
