3.
Level the Gravel Support Bed. An easy way to determine the levelness of the gravel support bed is to add water
(Figure 22) to the surface of the gravel. It may be necessary to add or remove
water to insure that the water level is at or near the same height of the gravel
level. Make certain that no foreign materials are left in the tank. This includes the
bags that the gravel is shipped in.
Installing Activated Carbon Filter Media
1.
Before adding the Activated Carbon, verify that the correct type and amount of
Activated Carbon for the filter you are installing is on site. If the correct type and
amount
(Table
5) of Activated Carbon is not on site, contact the Culligan Dealer
that sold you the filter.
2.
Slowly pour in the Activated Carbon. It is recommended that a funnel be used on
those units with spin top and handhole covers, when loading Activated Carbon into the media tank. Make cer-
tain that no foreign material is left in the media tank.
3.
With the MVP controller unpowered, rotate the position dial to the Backwash (#1) position. Slowly open the inlet
isolation valve and allow the media tank to slowly fill up with water until the water level covers the mineral bed.
The freeboard dimension should be checked at this time. If the freeboard dimension is correct, rotate the posi-
tion dial to the Home (H) position at this time.
4.
Do not install the spin top, handhole or manhole cover(s) at this time. Allow 24 hours for the air to escape from
the media tank.
Installing Depth Filter Media
1.
Before loading the different types of media, verify that the correct type and amount
the filter you are installing is on site. If the correct type and amount of each media is not on site, contact the
Culligan Dealer that sold you the filter. The media must be loaded into the mineral tank in the proper order to
assure proper filter operation. It is recommended that a funnel be used on those units with spin top and hand-
hole covers, when loading each layer of media into the media tank.
2.
Layer 2 - Slowly pour in the 8-12 mesh garnet. Make certain that no foreign material is left in the media tank.
Carefully level this layer of media. With the MVP controller unpowered, rotate the position dial to the Backwash
(#1) position. Slowly open the inlet isolation valve and allow the media tank to slowly fill up with water until the
water level is just at the top of this layer of media. Close the inlet isolation valve and verify that this layer of
media is level.
3.
Layer 3 - Slowly pour in the 30-40 mesh garnet. Make certain that no foreign material is left in the media tank.
Carefully level this layer of media. Slowly open the inlet isolation valve and allow the media tank to slowly fill up
with water until the water level is just at the top of this layer of media. Close the inlet isola-tion valve and verify
that this layer of media is level.
4.
Layer 4 - Slowly pour in the 0.35-0.45mm red flint sand. Make certain that no foreign material is left in the media
tank. Carefully level this layer of media. Slowly open the inlet isolation valve and allow the media tank to slowly
fill up with water until the water level is just at the top of this layer of media. Close the inlet isolation valve and
verify that this layer of media is level.
5.
Layer 5 - Slowly pour in the 6-16 mesh carbon. Make certain that no foreign material is left n the media tank.
Carefully level this layer of media. Slowly open the inlet isolation valve and allow the media tank to slowly fill up
with water until the water level is just at the top of this layer of media. Close the inlet isolation valve and verify
that this layer of media is level.
6.
The freeboard dimension should be checked at this time. If the freeboard dimension is correct, rotate the posi-
tion dial to the Home (H) position at this time.
7.
Do not install the spin top, handhole or manhole cover(s) at this time.
