Loading the Media
NOTE Do NOT attempt to load the media without having the tank in its final position. Moving the tank once
the media has been loaded will be difficult at best.
1. Cover the top of the distributor pipe with tape that will prevent media from entering the distributor.
2. Use a funnel in the opening to add 6” of water to protect the distributor.
3. Load Media per Table 1 and
and
4. Clean tank threads, remove tape and check for any foriegn materials
NOTE Minimize the amount of water added until final positioning of the tank with the control valve mounted.
NOTE For Carbon Filters, the recommended soaking time for Cullar D media is 12 hours minimum with a sub-
sequent backwash for 30 minutes to remove fine particles.

Notes for preparing Greensand filters* for service:
1. Before adding the last Cullcite (anthracite) layer backwash the existing media including the Cullsorb for 10
minutes or until the water is clear at the drain. Then stop the backwash, depressurize the system and drain the
water down to within 3 - 4 inches above the media.
2. For every cubic foot of Culsorb media to be treated mix 0.5 gallons of 5.75% Chlorine Bleach or 0.2 gallons of
12% Sodium Hypochlorite into 6.5 gallons of water. Pour the chlorine mixture into the tank and allow it to soad
for a minimum of 4 hours.
3. Re-pressurize the unit, fill with water and rinse the media until the free chlorine residual at the drain is less than
0.2 mg/L.
4. Depressurize the unit and drain down the water and add the final Cullcite (anthracite layer. Fill with water and
initiate a complete backwash and rinse cycle.
5. The unit is now ready for operation.
*Greensand filters are not WQA or IAMPO certified.
