  • Page 3 Foreword The operating instructions contained herein are intended to serve as a guide for the operation of the water softener equipment. Since it is impossible to cover all operating contingencies and emergencies in a normal operating manual, the operator should read the manual and become familiar with it contents. They should also review the flow diagrams and vendor literature.

  • Page 4: Introduction

    Section 1: Introduction Long term, successful operation of any softening system depends upon the care and attention it receives. Ordinarily, water treatment systems will provide uniform performance after the initial start-up period. Total gallons between regenerations and treated water purity usually do not vary appreciably over the life of the resin as long as the incoming water does not change.

  • Page 5: Principles Of Ion Exchange

    Section 2: Principles Of Ion Exchange Ion Exchange Softening Process In order to understand the softening process of ion exchange, it is first necessary to understand the meaning of the terms which are used in the explanation. Hard Water, Cation Exchanger, and Brine are defined below and used to show how the ion exchange process works.

  • Page 6: Quality Of Effluent

    Quality Of Effluent If the hard water contains less than 500 ppm (about 30 grains) of calcium, magnesium and sodium salts, all expressed as CaCO 3 , it will be found that the effluent from a softener will contain an average of not more that 2 ppm actual total hardness (zero hardness by the soap test).

  • Page 7: Regeneration Steps

    Calculation Of Capacity - To determine the capacity of any cation exchanger, follow the procedure outlined below: From the analysis of the raw water, determine the actual total hardness as the sum of the calcium and magnesium concentrations expressed as CaCO 3 . If necessary, calculate the compensated hardness in accordance with the formula given above.

  • Page 8: Installation, Loading & Start-Up Procedures

    Section 3: Installation, Loading & Start Up Procedures Installation of Equipment 1. Before beginning installation, review the following instructions to familiarize yourself with the general placement of the equipment. 2. The operating pressure is between 30 to 100 psi. If pressure is higher than 100 psi, then a pressure regulator must be installed.

  • Page 9: Loading Of Gravel & Resin

    Loading Gravel & Resin 1. Before loading the gravel, check the lower distributor for possible damage from shipping. Making sure all laterals are in proper location. Do NOT proceed with loading if any damage is evident. 2. Once the distributor is checked out ok, plug the end of the distributor tube with a PVC cap/plug, clean rag or tape to keep the gravel and resin out of the center of the riser.

  • Page 10: Start-Up Procedures

    Start-Up Procedures 1. Once the piping and installation completed, and with the mineral in the tank, proceed with the following. 2. Open the manual by-pass valve. The manual inlet and outlet valves are to remain closed. 3. Plug electrical power of the main controller to a wall outlet (120v) 4.

  • Page 11: Operating & Regeneration Procedures

    Section 4: Operating & Regeneration Procedures 4.1 Normal System Operation The system is designed for fully automatic operation. Service runs will automatically terminate when an exhaustion end-point is reached. Although it should not be absolutely necessary to observe every regeneration, Operators should periodically witness a complete cycle to make sure that critical flow rates and steps have not gotten out of adjustment.

  • Page 12: Multi-Port Valve Operation

    Multi-Port Valve Operation (See Section 8 – Fleck 3900 Control Manual) Multi-port valve consist of Fleck 3900 multi-port double piston operated valve. The valve operates with upper and lower piston that moves on a seals and spacer assembly. The upper piston is for regeneration and the lower piston is for service.
  • Page 13 Section 5: Operator Responsibilities Operator Maintenance Long term, reliable system performance depends upon how conscientiously the equipment is operated and maintained. Operator responsibilities should include the following recommended practices: 1. Maintain Operating Logs - Operators should maintain close control of the process by monitoring system performance daily.
