Initial Backwash of the System
1. Referencing the instructions in the GBE Programming for Commerical Softeners and Filters, except for HF xN
Manual (P/N 01027295), cycle the control to the backwash position.
2. Cycle the control through the remaining steps and back to the home (service) position.
Installation Wrap Up
“High Efficiency Twin 1.5 Water Softeners—Flow Rate Data (gpm)” on page 66
provides the expected flow rates to the
drain during the various steps of the regeneration process.
Creating Brine
Once salt has been added to the brine tank the control valve must be manually cycled to the brine refill cycle to create the
required amount of brine for the unit’s first regeneration. Allow the valve to refill for the cycle #5 programmed time.
NOTE If the control valve is not cycled to the brine refill cycle there will be no brine for regeneration.
NOTE The salt level must be checked frequently; in some cases, after each regeneration. After the brine refill
step is finished, add salt. To ensure complete brine saturation in wet storage, maintain a salt depth of
at least 18 inches.
NOTE Use the
and the GBE Programming for Commercial Softeners and Filters (except
for HFxN) Manual (P/N 01027295) to set the HE 1.5” Twin Softener to the proper time for refilling the
brine tank with water.
Sanitize the System
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:
• At start-up time.
• 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 harm-
less 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.
If the unit uses Culligan® Sofner-gard® or other compounds containing sodium
hydrosulfate, sodium bisulfate, or any other reducing agent, disconnect the device
feeding the chemical(s) 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.
2. Pour directly into the brine chamber one-cup of common household bleach (5.25% sodium hypochlorite) for
each cubic foot of resin in the tank.
3. Manually start recharge. Allow the unit to complete the recharge cycle automatically.
NOTE If tastes and odors return frequently, even after sanitization, a continuous chlorination system may be
needed. Send a water sample to a qualified laboratory for bacterial analysis.
