Valve Installation and Start-Up Procedures

Installation Instructions

1. Place the softener tank where you want to install the unit.

NOTE: Be sure the tank is level and on a rm, clean base.

2. Perform all plumbing according to local plumbing codes.

3. Cut the 1.05” or 32mm distributor tube ush with the top of the tank (A). — Deburr the outside of the tube (B) after cutting. — Lubricate the o-ring (C) with non-petroleum based grease. . Lubricate the distributor 0-ring seal and tank 0-ring seal. Use only non-aerosol silicone lubricant.

5. Load media and place the control valve on the tank.

6. All soldering MUST be done on any connections requiring soldering prior to connecting the main control valve. The main control valve will by damaged if it is connected at the time of soldering.

7. Apply Teon tape to all threaded ttings.

8. On units with a bypass, place in Bypass position. — Turn on the main water supply. — Open a cold soft water tap nearby and let water run a few minutes or until the system is free of foreign material (usually solder) resulting from the installation. Close the water tap when water runs clean.

9. Make plumbing connections to valve.

10. Plug the valve into an approved power source.

NOTE: Make all electrical connections according to codes.

11. Place the bypass In Service position. Cycle the valve to the Backwash position, and let the water ow slowly into the mineral tank until the air is purged from the unit.

12. Add water to the brine tank until the top of the air check is covered. Manually step the valve to the Brine Draw Position, and allow the valve to draw water from the brine tank until it stops.

NOTE: The air check will check at approximately the midpoint of the screened intake area.

13. Manually step the valve to the Brine Rell Position, and allow the valve to return to In Service automatically. 1. With the valve In Service, check that there is at least 1” of water above the grid in the brine tank, if used.

15. Fill the brine tank with salt.

16. Allow the control to run automatically. Setup is now complete.

Time Clock or Day of the Week Regeneration Valves

In normal operation the Time of Day Display may be viewed at all times. The control operates for a preset number of days between Regeneration cycles. When the number of days since the last Regeneration reaches the preset number of days, a Regeneration cycle initiates at the preset Regeneration Time. Program the number of days between Regeneration cycles and the Regeneration time using the 7000 Control Start-Up Procedures.

Flow Meter Equipped Valves – General

Flow meter equipped valves calculate the volume of water that the system can treat between Regeneration cycles based on the system capacity which is preset by the system manufacturer in a Master Programming Mode and the feed water hardness which is programmed in the Start-Up procedure safety factor (Master Mode only). The remaining system capacity displays in gallons or liters. The display has a range of 0 to 9999 (gallons or liters). If the remaining capacity exceeds 9999 liters when in the Metric Mode, then the display changes to millions of liters and a letter t is displayed as the rst digit. The display then has a range of t1.0 (1,000,000) to t1.9 (1,900,000).

Flow Meter Equipped Valves – Immediate Regeneration Mode

The Time Of Day display alternates with the Volume Remaining display in gallons or liters. The Meter dot ashes in direct relation to the water ow rate through the unit. As treated water is used, the Volume Remaining display counts down from a maximum value to zero and initiates a Regeneration cycle immediately.

Page 6

7000 Control Operation and Settings

Flow Meter Equipped Valves – Delayed Regeneration Mode

In Normal operation the Time Of Day display alternates with the Volume Remaining display. The ow dot ashes in direct relation to the water ow rate through the unit. As treated water is used, the Volume Remaining display counts down from a maximum value to zero. If the reserve is reached, a Regeneration queues. The display shows all dashes if the entire volume is depleted before the scheduled Regeneration time. At the preset Regeneration Time, a Regeneration cycle initiates.

Control Operation During Regeneration

In Regeneration the display shows the Regeneration status two ways:

• When the valve advances to the next position, the display ashes the number of that next position followed by three dashes.

• Once the valve reaches a position the display shows that position and number of minutes left in that Regeneration step.

NOTE: If the step time exceeds 100, the leading digit ashes.

• Once all Regeneration steps are complete, the valve returns to In Service and resumes normal operation. NOTE: Pressing the Extra Cycle Button during a Regeneration cycle immediately advances the valve to the next cycle step position and resumes normal step timing.

Control Operation During Programming

The control enters Program Mode with the valve In Service. While in Program Mode the control continues to operate normally, monitoring water usage and keeping all displays up to date. Control programming is stored in memory permanently. There is no need for battery backup power.

Control Operation During a Power Failure

During a power failure all control displays and programming are stored for use upon power re-application. An inaccurate or ashing Time of Day display indicates that a power outage has occurred. During power failure the control:

• Is fully inoperative and any calls for Regeneration are delayed.

• Upon power re-application, resumes normal operation from the point that it was interrupted.

• Does not monitor the volume of water used during a power outage.

• In Delay Regeneration types, the reserve capacity is set to 1/3 the capacity.

Manually Initiating a Regeneration

A Regeneration cycle may be initiated manually (referred to as an Extra Regeneration Cycle). There are two options when starting an Extra Regeneration Cycle:

• Press and release the Extra Cycle Button: — Flow Meter - Immediate Regeneration controls immediately go into a Regeneration cycle. — For Time Clock and Flow Meter - Delayed Regeneration controls, the In Service dot begins to ash immediately and a Regeneration occurs at the pre-programmed Regeneration time.

• Press and hold the Extra Cycle Button for ve (5) seconds: — For Time Clock and Flow Meter - Delayed Regeneration controls, the control immediately begins the Regeneration cycle.

7000 Control Start-Up Procedures

Set Time of Day

• Press the Set Up and Set Down buttons to set time of day. — Metric = 2 hour clock — US = 12 hour clock with PM indicator light

Enter Control Programming Mode

— Press and hold both the Set Up and Set Down buttons for 5 seconds to enter Programming Mode. When the program mode is entered, the program dot turns on.

The 7000 controller performs 5 basic types of Regeneration systems. The type of system is selected by the system manufacturer and set in the Master Programming Mode. Basic systems are:

• Time Clock

— The control operates for a preset number of days between Regeneration cycles. On the day that a Regeneration cycle is required the system regenerates at the preset Regeneration Time.

• Meter Immediate

— The control regenerates immediately when the remaining capacity (volume of water that can be treated before a Regeneration is required) drops to 0.

• Meter Delayed

— The control regenerates on the day that the remaining capacity drops to less than the reserve volume. Regeneration starts at the preset Regeneration Time.

• Meter Delayed - Variable Brining

— The control regenerates on the day that the available volume of softened water drops to or below the reserve volume. Regeneration starts at the set Regeneration Time. With the variable brining option activated, the time setting for Cycle 1 is automatically calculated based on the volume of treated water at the time of regeneration. Cycle time 1 will not exceed the original time setting and is never less than 1 minute.

• Day of the Week

— The control regenerates at the scheduled Regeneration Time on the day(s) of the week which are set by the user.

The Current Day of the Week display will alternate with the Time of Day when the control is In Service. The Day of the Week display will increment each day at 12:00 A.M. (Midnight).

1. Feed water hardness (Display Code H).

NOTE: The feed water hardness setting only displays when the system is set to operate as a Meter Immediate or Meter Delayed system type.

— Press the Set Up or Set Down buttons to set the amount of feed water hardness in grains/gallon (U.S.) or degrees (metric). The system automatically calculates treated water capacity based on the feed water hardness and the system capacity preset in the Master Programming mode. “Calc” is displayed during calculations.

Example: Range: 4 – 199 U.S. and metric

— To program 9 grains / gallon (U.S.) or 9 degrees (metric) [ H -- 9] — Press the Set Up and Set Down buttons to adjust this value. — Press the Extra Cycle button once to advance to the next step.

2. Regeneration Time (No display Code)

NOTE: The Regeneration Time setting does not display in Meter Immediate Regeneration Mode since the system regenerates immediately when the available capacity reaches 0.

Identify the Regeneration Time display by observing a non-ashing colon between two sets of numbers. Set the desired time of day for Regeneration to occur.

Example: 2 o’clock A.M. regeneration time: [ 2:00 ] (P.M. Indicator Dot Off)

— Press the Set Up and Set Down buttons to adjust this value. — Press the Extra Cycle button to exit the programming mode or press and hold the Set Up and Set Down buttons simultaneously for ve (5) seconds to enter the Extended Setup Programming Mode.
