Once this is complete, add the MetSorb media in the same manner. Use all of the media
provided. Depending on the capacity of the system, there will only be enough media to fill
the tank to about 1/2 to 3/4 full. This is normal. The media tank should never be filled to the
top of the tank as the remaining space, known as the “freeboard,” is necessary for the media
to have room to expand during the backwash cycle.
Once you have finished adding the media to the tank, remove the tape from the distributor
tube. Be careful not to pull upwards on the riser tube while doing this as it is important that
the distributor remain in its recess at the bottom of the tank.
Fill the media tank with water up to within a couple of inches of the top of the tank. This will
allow the media to pre-soak, thereby preventing media loss during the initial backwash.
DO NOT INITIATE A REGENERTION OF THIS SYSTEM
FOR A MINIMUM OF 2 HOURS AFTER ADDING THE
WATER TO ALLOW ADEQUATE PRE-SOAKING.
BACKWASHING BEFORE THE MEDIA IS SATURATED
MAY CAUSE A LOSS OF MEDIA AND POTENTIAL
DAMAGE TO THE CONTROL VALVE.
Attach the upper screen to the underside of the control
valve. Be sure to twist clockwise and lock it into place.
Apply a small amount of lubricant to the top inch of the
outside of the riser tube and to the tank o-ring seal.
Note: Only use food-grade silicone lubricant. A small bag of
lubricant is provided in the small parts bag. Do NOT use petroleum jelly.
The control valve can now be secured to the top of the tank. Before attaching the valve,
check to make sure that there is no debris such as gravel or media in the tank threads.
Screw the control valve onto the tank. Make sure that the riser tube inserts into the center
hole in the upper screen and the control valve as you screw down the valve. The control
valve should be hand-tightened (clockwise). Do NOT use the control valve's timer assembly
