-
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.
