PREPARATIONS
MEDIA INSTALLATION (WHEN NECESSARY)
When
larger units cannot be loaded due to weight restrictions, media will be shipped
pre-measured in separate containers. Follow the steps below for proper media loading.
a)
Remove the valve from the mineral tank.
Add bottom cone only in TO Models
b)
Temporarily plug the open end of the riser
tube to ensure that no resin or gravel falls
down into the distribution. The riser
(distributor) remains inside the tank seated in
the depression at the bottom.
Plug tube with a tape. Remove after media
is loaded.
c)
Fill support bed first.
The media will not always spill down inside
the tank and may need to be swept inside.
The large funnel (sold separately makes filling
the tank easier and neater. (Or an empty 1
gallon or 4 liter container with the bottom cut
out makes a good funnel.)
