.Turn off the water to the unit.
.Disconnect the unit from your plumbing.
.Carefully unscrew the valve off the top of the
tank.
.Inside of your tank is plastic tubing known as
the “riser tube”. The riser tube sucks up the water from the bottom of the
tank during normal operation, and forces water to the bottom of the tank
during the backwash operation.
.After removing the control valve from the tank,
remove the riser tube from inside the mineral tank.
.Lay the tank on its side, or lay over trash can,
to remove media. Rinse the inside of the tank clean with a garden hose.
.Discard old resin. Save old gravel.
.Make sure your media tank is standing straight up.
.Put a piece of tape over the top of the riser
tube to prevent media from entering the tube while you are loading the media.
.Put the media funnel included with your system in
the top of the media tank with the riser tube still inside and centered. The
gravel goes into the tank first. When pouring in the gravel, make sure the
riser tube is firmly on the bottom of the tank.
.Once you add your media, if the riser tube is
pulled out of the gravel, it is impossible to put it back in without removing
the other media from the tank.
.Pour the resin/media into the funnel, slowly
letting it fall down inside the media tank around the riser tube. If you have
a twin alternating system, divide the resin/media equally between the two
tanks.
.When you have poured all of the resin/media into
the media tank, it should be approximately 3/4 full.
.Remove the funnel and then the tape from the top
of the riser tube.
.Brush any loose resin/media off the top opening
of the tank.
.Clean the top edge with a cloth so the O-ring can
seal securely to the valve base.
.Look at the bottom of your control valve and you
will see an upper basket Inside of the basket, the valve has O-rings that will
seal on the riser tube. Tilt the valve over on top of the media tank making
sure the top of the riser tube inserts inside the opening of the upper basket.
Guide the riser into the O-ring seal and tighten gently.
.Screw the valve back onto the top of the tank.
.Reconnect your plumbing to your unit.
.Turn the water to the unit on and check for
leaks. Leave all faucets turned off inside the house, and open a single faucet
(such as an outside faucet) letting the water run for 3-5 minutes. This rinses
the new resin/media off inside the tank, and any particles or color will rinse
out through the one open faucet, and not throughout your home plumbing system.
