IMPORTANT: SECTION 1: BEFORE INSTALLATION
Congratulations! We believe your purchase of this water softener will prove to be a very wise choice. When properly installed, operated, and maintained, your
new softener will provide years of dependable service. Before starting the installation please read this manual all the way through for an overview, and then
follow the installation in proper sequence. Failure to follow instructions will void warranty.
Inspecting And Handling Your 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 your water should be made prior to the selection of your water conditioning equipment. Your dealer will generally perform this service for you,
and may send a sample to the factory for analysis and recommendations. Enter your analysis below for your permanent record.
Analysis of Your Water:
Hardness gpg Tannins (Humic Acid) ppm
Iron (Fe) ppm Hydrogen Sulfi de (H
2
S) ppm
Manganese (Mn) ppm Other ppm
pH ppm
Other ppm
IMPORTANT NOTES
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 reduce 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, 3MAPPM System is recommended for use on waters containing more than 2 ppm of iron.
