Culligan International Water Softener CSM-600-3

At Start-up, after infrequent use (idle for one week or more) or every 3 - 6 months if on a private water supply.

A water softener in daily use on a potable water supply generally requires no special attention other than keeping the salt tank filled. Occasionally, however, a unit may require sanitization under one of the following conditions:

• After standing idle for a week or more.

• On private supplies, the appearance of off-tastes and odors, particularly if musty or “rotten egg” (caused by harmless sulfate-reducing bacteria).

NOTE If the water supply contains iron, regenerate the softener before sanitizing to remove iron from the resin.

CAUTION! HAZARD FROM TOXIC FUMES! CHLORINE BLEACH AND COMMON IRON CONTROL

CHEMICALS MAY GENERATE TOXIC FUMES WHEN MIXED.

Remove clean-out plug and inspect the flow washer area (Figure 108)

Remove any foreign material lodged in or near the flow washer(s) (Figure 109)

NOTE: AVOID USING A SHARP OBJECT WHICH MIGHT CUT OR DAMAGE THE RUBBER FLOW WASHER(S). SHOULD IT NOT BE POSSIBLE TO CLEAR THE CONTROLLER THROUGH THE CLEAN OUT PLUG, REMOVAL OF THE FLOW CONTROL NIPPLE WILL BE REQUIRED TO GAIN BETTER ACCESS TO THE FLOW WASHER AREA.

If removal of the Backwash Flow Control nipple is necessary, disconnect the flexible tubing from the compression fitting.

Carefully separate the nipple from both the drain line and the Brunermatic valve (Figure 110)
