CAUTION

To reduce the risk associated with property damage due to water leakage:

• Read and follow Use Instructions before installation and use of this system;

• Installation must comply with existing state or local plumbing codes;

• Protect from freezing. Drain system when temperatures drop below 40°F (4.4°C);

• Do not install if water pressure exceeds 100 psi (689 kPa). If the system water pressure exceeds 100 psi, the installation must

use a pressure limiting valve. Contact a licensed plumbing professional if you are uncertain how to check your water pressure;

• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention;

• When water supply is shut off, shut off fuel or electric power to water heater;

• Do not use torches or other heat sources near plastic plumbing, as damage may occur;

• Take care when using pliers or pipe wrenches to tighten plastic ﬁ ttings, as damage may occur;

• On plastic ﬁ ttings, use thread sealing tape only. Never use pipe sealant or pipe dope on plastic ﬁ ttings, as damage may occur;

• Do not bend spring on ﬂ oat assembly or damage to the vent may result;

• Do not install this system in direct sunlight or outdoors without protection from precipitation.

To reduce the risk associated with property damage due to plugged water lines:

• Pay particular attention to correct orientation of control valve. Water ﬂ ow should match arrow on control valve

. The Inlet and

Outlet of other water treatment equipment products will vary depending on the control valve brand used.

IMPORTANT NOTES

• Failure to follow instructions may result in leakage and will void warranty.

SECTION 1: BEFORE INSTALLATION

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:

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

the air check in the brine well 1" before adding new salt. Perform approximately once a

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 capacity 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.

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 (H2S) 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.

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.
