Before starting the installation we suggest reading this manual all the way through for an overview, and then follow the installation steps 
in the proper sequence. IMPROPER INSTALLATION could void the warranty. Installation should be completed by a qualifi ed plumber.

INSPECTING AND HANDLING THE WATER SOFTENER: 

Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection. 
Handle the equipment with care. Damage can result if dropped or if the brine tank is set on sharp, uneven projections on the fl oor. When 
handling, do not turn the water softener unit upside down. 

MAKE SURE YOUR WATER HAS BEEN THOROUGHLY TESTED: 

An analysis of the water should be made prior to the selection of water conditioning equipment. The dealer will generally perform this 
service, and may send a sample to the factory for analysis and recommendations. Enter the analysis below for a permanent record.

IMPORTANT NOTES

Hydrogen sulfi de (H

2

S) must be tested for at the well site. For accuracy, the sample must be drawn with the pump RUNNING, and the 

test be completed within ONE minute after the sample is drawn. 

Softeners are designed to remove hardness but can handle reasonable amounts of soluble iron if consideration is given to content when 
selecting model and regeneration settings. To treat sulfur (hydrogen sulfi de), bacterial iron, precipitated iron or very high levels of soluble 
iron requires special equipment in addition to a water softener. For best results, a Chem-Free Iron Reduction Filter is recommended for 
use on waters containing more than 2 ppm of iron.

MAINTENANCE

REPLENISHMENT OF SALT SUPPLY: 

The salt storage capacity of the brine tank is approximately 280 lbs. (127 kg). During each regeneration a specifi c amount of salt is 
consumed, thus requiring its periodic replenishment (the frequency is dependent on the regeneration schedule). Always replenish salt 
before the supply is exhausted to assure a continuous supply of softened water. 

TYPE OF SALT TO USE: 

Any type of water softener salt may be used. There are advantages and disadvantages to every type of salt. Please ask the local dealer 
for his advice. The unit is designed to compensate for the disadvantages. 

BRINE TANK CLEAN-OUT: 

To prevent service problems the brine tank should be emptied and fl ushed out with a garden hose when dirt and other insolubles ac-
cumulate. The clean-out frequency depends on the type salt used and regeneration frequency. The clean-out should be done when the 
salt level is low. Steps to follow: 
1)   Disconnect brine line at either end. 
2)   Turn brine tank upside down and discard old salt. Remove salt grid plate.
3)   Rinse out with a garden hose. 
4)   Reconnect brine line. 
5)   Add enough water to brine tank to cover the air check in the brine well 1" before adding new salt. Perform approximately once a 

year if rock salt is used; with other types of salt, approximately once every other year. 

PREVENTING IRON-FOULING OF MINERAL BED: 

If iron is present in the water supply, the softener mineral bed will eventually become iron-fouled, resulting in reduced softening capac-
ity and rust-stained fi xtures. Mixing one to two ounces of IRON-X Mineral Cleaner with every 80 lbs. of salt added to brine tank will 
minimize these problems from occurring. IRON-X is available from the dealer. 

PERIODICALLY CHECK TIME OF DAY SETTING: 

Power outages will cause TIME OF DAY timer setting to become incorrect. To reset, refer to appropriate HOW TO SET TIME CLOCK 
REGENERATION CONTROL, Section 3. 

MALFUNCTION OF UNIT: 

The water softener, under normal conditions, should provide years of trouble-free service; however, since it is a mechanical device, it 
can malfunction. (Refer to Section 4, SERVICE INSTRUCTIONS, if necessary). 

CHANGE OF OPERATING CONDITIONS: 

Should the daily water usage, or water quality change, the regeneration program settings may have to be adjusted. Consult the dealer 
if any of the above occur.
