Connect Valve and Salt Tank Drains

CONNECT THE VALVE DRAIN HOSE

Take a length of 3/8” inside diameter drain tubing and attach one end to the drain fitting. See Fig. 16. Use a tube clamp to hold it in place. Put the other end of the tubing over a floor drain, into a laundry tub, standpipe, or other suitable drain. Check your local codes.

Leave an air gap of about 1-1/ 2'' between the end of the hose and the drain. This gap is needed so you don’t get a backflow of sewer water into the softener. Do not put the end of the hose into the drain or con- nect without the air gap.

Place and support the hose so it does not kink or have sharp bends. Secure the hose end so water pressure does not cause the hose to “whip”. Tie or wire it in place. Do not pinch the hose shut. The softener will not work if this drain hose is pinched, plugged, closed or restricted in any way. Direct drain flow down into drain from drain line as flow could possibly over shoot the drain cover.

Keep the hose lower than the drain fitting. In some homes, to get to a drain you must raise the hose and run it overhead. If you need an overhead drain, do not raise the hose more than 8' above the floor. A copper drain tube is best to use.

COPPER DRAIN TUBE: The local plumbing codes may require the use a copper valve drain tube. A cop-

per tube is also best to use for an overhead drain. Use a copper drain tube if the softener is installed outside, or in the sunlight. Heat from the sun can soften, flatten and close up some kinds of tubes.

To adapt a copper drain tube to the softener, buy a compression fitting (1/4'' female pipe threads x 1/2'' O.D. tube) and tubing from your local hardware store.

CONNECT SALT TANK OVERFLOW TUBING

1.Locate the rubber grommet, tube adaptor and tube clamp (see Fig. 16) that are in the parts bag.

2.Push the grommet into the hole in the salt tank wall so half is inside and half is outside.

3.Push the bigger end of the tube adaptor into the grommet.

4.Push one end of a length of 3/ 8'' I.D. tubing onto the tube adaptor, using the tube clamp to hold it in place.

5.Put the other end of the tubing over the floor drain.

IMPORTANT: Overflow water must run downward through the tubing. Do not raise the tubing higher than the grommet and tube adaptor. See Fig. 16.

IMPORTANT: Do not connect to the valve drain hose you installed in step 1. Both drains must have a separate hose or tube.

NOTE: Overflow drain tubing is available from Sears. See parts list in back of manual.
