Sanitizing Instructions - Culligan SILVER SERIES Installation And Operating Instructions Manual

Sanitizing Instructions

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 sanitation under one of the following conditions:
• The unit has stood idle for a week or more (the premises vacant or the residents on vacation).
• On private supplies, the appearance of off-tastes and odors, particularly a musty or "rotten egg" odor .
For occasional occurrences, the softener can be sanitized with household bleach as follows.
NOTICE: If the water supply contains iron, regenerate the softener before sanitizing to remove accumulated iron
from the Cullex
WARNING: HAZARD FROM TOXIC FUMES! CHLORINE BLEACH AND
COMMON IRON CONTROL CHEMICALS MAY GENERATE TOXIC FUMES
WHEN MIXED.
• IF THE UNIT USES CULLIGAN
CONTAINING SODIUM HYDROSULFITE OR SODIUM BISULFITE, OR ANY OTHER
REDUCING AGENT, DISCONNECT THE DEVICE AND MANUALLY REGENERATE THE UNIT
BEFORE SANITIZING.
• DO NOT USE THIS PROCEDURE IF THE SOFTENER SALT CONTAINS IRON CONTROL
ADDITIVES.
1. Remove the brine tank cover and the small cover on the brine valve chamber.
2. Pour directly into the brine chamber 1 cup (9-inch units) or 2 cups (12-inch units) of common household
bleach (5-1/4% sodium hypochlorite).
NOTICE: Do not use lemon scented bleaches, or similar bleaches that contain perfumes.
3. Manually start a recharge cycle. Allow the unit to complete the recharge cycle automatically.
If tastes and odors return frequently, even after sanitization, additional equipment may be required. Have a laboratory
analysis performed to determine the possible cause of the odor. Contact Household Application Engineering for
assistance. Also, have the consumer send a sample to a qualified laboratory for bacterial analysis.
