Page 3: Preinstallation Instructions For Dealers
PREINSTALLATION INSTRUCTIONS FOR DEALERS: The manufacturer has preset the water treatment unit’s sequence of cycles, cycle times, salt dose, exchange capacity and salt dose refill time. The dealer should read this page and guide the installer regarding hardness, day override, and time of regeneration, before installation.
Page 4 1. NORMAL OPERATION POSITION: The inlet and outlet handles point in the direction of flow indicated by the engraved arrows on the control valve. Water flows through the control valve for normal operation of a water softener. During the regeneration cycle this position provides regeneration water to the unit, while also providing untreated water to the distribution system (Fig.
Page 5: Installation
INSTALLATION: GENERAL INSTALLATION & SERVICE WARNINGS The control valve, fittings and/or bypass are designed to accommodate minor plumbing misalignments. There is a small amount of “give” to properly connect the piping, but the water softener is not designed to support the weight of the plumbing. Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere.

6. INLET/OUTLET PLUMBING: Be sure to install Bypass Valve onto main control valve before beginning plumbing. Make provisions to bypass outside hydrant and cold hard water lines at this time. Install an inlet shutoff valve and plumb to the unit’s bypass valve inlet located at the right rear as you face the unit.
Page 7: Programming Procedures
PROGRAMMING PROCEDURES: 1. Set time of day: Time of day should only need to be set after extended power outages or when daylight saving time begins or ends. If an extended power outage occurs, the time of day will flash on and off indicating that the time should be reset.
Page 8: Operating Displays And Instructions
2. Programming cont’d: STEP 4 – REGENERATION HOUR: The manufacturer has factory set 2:00 A.M. as the default. This is the hour of day for regeneration and can be reset by using + or — buttons. “AM/PM” toggles after 12. The default time is 2:00 a.m. (recommended for a normal household). Press to go to step 5.
Page 9 3. MANUAL REGENERATION: Sometimes there is a need to regenerate before the control valve calls for it. This may be needed if a period of heavy water use is anticipated or when the system has been operated without salt. • To initiate a manual regeneration at the next preset regeneration time, press and release MANUAL REGENERATION .
Page 10 ERROR 5. ERROR MESSAGE: If the word “ERROR” and a number are alternately flashing on the display record the number and contact the dealer for help. This indicates that the control valve was not able to function properly. 6. BRINE TANK MAINTENANCE AND SALT: Refill the brine tank as necessary, making sure at least 1/3 of the brine tank is full at all times.
