- Page 4 Installation Note: Due to the Nitrate System abilities to remove bi-carbonate (alkalinity) from the water, a dramatic reduction in pH of the treated water may be experienced. If this occurs, a whole house or upflow filter with neutralizer or Neu-Cor media may be required. Installation Requirements •...
- Page 5 Installation Installation Procedure Water Supply Connections and Bypass Valve To allow for filter servicing, swimming pool filling or lawn sprinkling, a manual bypass valve has been installed at the factory. The bypass allows water to be manually routed around the filter. 1.
- Page 6 Installation -Brine Line and Overflow Connection- Note: Your brine tank comes with two brine lines. Black is for outdoor installation. Opaque is for indoor installation. Feed one end of brine line to brine line connection on Inside the brine tank, remove the cap from the top of the brine well.
- Page 7 Installation How To Calculate Regeneration Frequency Note: The quantity of both nitrate and sulfate must be known for proper regeneration calculation. Step 1: Convert Nitrate (NO3) and Sulfate (SO4) to Calcium Carbonate (CaCO3). Nitrate Divide ppm (mg/l) of Nitrate by 62 and multiply by 50.1 Example : (50 ppm NO3/62) x 50.1 = 40.4 ppm as CaCO3...
- Page 8 Installation Step 4: Calculate the grains capacity for the system being installed. Example : MN15 = 1.5 cu. ft. x 8,500 grains / cu. ft. = 12,750 total grains capacity Step 5: Calculate total grains of nitrate. ppm as CaCO = grains of Nitrate 17.1 Example:...
- Page 9 Installation Filling The Brine Tank With Salt To expect a high level of performance and reliability, a salt manufactured specifically for water softeners must be used. Salt of this grade is virtually free from dirt and other particulate that would eventually cause the nitrate filter to malfunction.
- Page 10 Control Start-Up Procedure Put unit in bypass using the handles behind the control valve. Start a regeneration by pressing and holding the set change button for 3 seconds. The display may show zeros or a 1, repeat holding the set change button. Display on unit should read 1-10 (Step 1-10 min).
- Page 11 Programming the Control Valve - Programming The Control Valve - 1. Set time of day. 2. Set a.m. or p.m. 3. Set water hardness in grains per gallon (gpg). Note: If the water contains iron and / or manganese, multiply the total parts per million (ppm) by “four” (4) and then add to the grains per gallon (gpg) of hardness.
- Page 12 Programming the Control Valve Normal Operation 1. Home Display Metered models alternate the Time of Day and Gallons left until the next regeneration. The meter will count down to zero (0000) and then regenerate at the scheduled time set. 2. Battery Back-Up (Uses a standard 9-volt alkaline battery.) Features of Battery Back-Up: •...
- Page 13 Master Programming Mode Master Programming Mode To enter Master Programming Mode, press and hold both buttons for 5 seconds. Note: All Master Programming functions have been preset at the factory. Unless a change is desired, it is NOT necessary to enter Master Programming Mode. 1.
- Page 14 Utilizing Bluetooth Control For simplified set up and control, please install the Legacy View on a compatible Bluetooth 4.0+ enabled smart phone or tablet. 1. Download and install the Legacy View app from the Google Play Store, Apple App Store 2.
- Page 15 Set Up Utilizing Bluetooth App Change Time of Day (Press “SET” to set time automatically based on device). For Filters: Set Backwash Frequency This sets the amount of day between backwash cycles Set Regeneration Time Example: For 2a.m., just type 2, choose a.m., and press ‘OK’ Note: If you have a filter and a softener the valves should be set to regenerate at different times.
