General Residential Installation Check List
WATER PRESSURE: A minimum of 25 pounds of water pressure is required for regeneration valve to operate
effectively.
ELECTRICAL FACILITIES: An uninterrupted alternating current (A/C) supply is required. Please make sure your
voltage supply is compatible with your unit before installation.
EXISTING PLUMBING: Condition of existing plumbing should be free from lime and iron buildup. Piping that is built up
heavily with line and/or iron should be replaced. If piping is clogged with iron, a separate iron filter unit should be
installed ahead of the water softener.
LOCATION OF SOFTENER AND DRAIN: The softener should be located close to a clean working drain and
connected according to local plumbing codes.
BY-PASS VALVES: Always provide for the installation of a by-pass valve if unit is not equipped with one.
CAUTION: Water pressure i s not to exceed 120 p.s.i., water temperature is n ot to exceed 110°F, and th e unit cannot
be subjected to freezing conditions.
Installation and Start-up Procedures
1. Place the softener tank where you want to install the unit, making sure the tanks are level and on a firm base.
2. During cold weather it is recommended that the installer warm the valve up to room temperature before operating.
3. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain should be a
minimum of 1/2″. Backwash flow rates in excess of 7 gpm or length in excess of 20′ require 3/4″ drain line.
4. The 1″ distributor tube (1.050 O.D.) should be cut flush with top of each tank. Note: Only use silicone lubricant.
5. Lubricate the distributor
6. Solder joints near the drain must be done prior to connecting the Drain Line Flow Control fitting (DLFC). Leave at
least 6″ between the DLFC and solder joints when soldering pipes that are connected on the DLFC. Failure to do
this could cause interior damage to DLFC.
7. Teflon tape is the only sealant to be used on the drain fitting.
8. Make sure that the floor is clean beneath the salt storage tank and that it is level.
9. Place approximately 1″ of water above the grid plate. If a grid is not utilized, fill to the top of the air check in the salt
tank. Do not add salt to the brine tank at this time.
10. On units with a by-pass, place in by-pass position. Turn on the main water supply. Open a cold soft water tap
nearby and let run a few minutes or until the system is free from foreign material (usually solder) that may have
resulted from the installation. Once clean, close the water tap.
11. Place the by-pass in service position and let water flow into the mineral tank. When water flow stops, slowly open a
cold water tap nearby and let run until the air is purged from the unit.
12. Plug the valve into an approved power source. Once the valve is powered it will drive to the Service Position.

15. Manually initiate a regeneration cycle and allow water to run to drain for 3 to 4 minutes. Next, manually step the
valve through a regeneration cycle checking valve operation in each step.
A. Initiating Regeneration (Depending on the timer regeneration type you have one or two (2) Options):
1. Press and Release the Extra Cycle Button. With Immediate Regeneration Timers the control will go into
regeneration immediately. With Delayed Regeneration Timers the Service Arrow will begin to flash
immediately and a regeneration will occur at the preset regeneration time (i.e. 2:00 a.m.)
2. Press and Hold for 5 seconds the Extra Cycle Button. The control will go into regeneration immediately.
B. Control Operation During Regeneration:
1. During regeneration the control will display the regeneration step number the valve is advancing to, or has
reached, and the time remaining in that step.
For Example:
(Valve is advancing to Regeneration
Step #1)
(#1 flashing)
(Regeneration arrow on)
2. When the first cycle step is reached, a red LED will turn on to indicate the current regeneration cycle step.
For Example:
(Regeneration Step #1 has
been reached)
(10.0 minutes remain in Step #1)
3. Pushing the Extra Cycle Button during a regeneration step will immediately advance the valve to the next
regeneration step position.
4. Pushing the Up or Down Set Button during a regeneration step will adjust the time remaining in that current
regeneration step. Programmed Regeneration Steps will not be changed.

Control Operation (Cont’d.)
Control Operation During A Power Failure
During a power failure all control displays will be turned off and regeneration cycles delayed. The control will otherwise
continue to operate normally until line power is restored or battery backup power is lost.
1. If battery backup power is never lost during a power outage, the control will continue to operate normally, without
the loss of data, until line power is restored.
2. If battery backup pow er is lost during a power outage, the control will store the current Time Of Da y, Volume
Remaining, Regeneration Cycle Status, and various diagnostic displays. These stored displays will then be used
upon line power restoration until updated ones are created. To indicate this type of failure, the control will flash the
current Time Of Day Display to indicate that this display and the V olume Remaining Display may not be correct.
Control Operation During Regeneration
In regeneration the control will display what regeneration step number the valve is advancing to, or has reached, and
the time remaining in that step. Once all regeneration cycle steps have been completed the valve will return to service
and resume normal operation.
1. First the Regeneration Arrow turns on. Then the display below is viewed to indicate that the valve is advancing to
the first regeneration cycle step.
Backwash
For Example:
(Valve is advancing to
Regeneration Step #1)
(#1 flashing)
2. When the first cycle step is reached, the display becomes as shown below, A red LED will also turn on to indicate
the current regeneration cycle step.
For Example:
(Regeneration Step #1 has
been reached)
(10.0 minutes remain in Step #1))
3. Pushing the Extra Cycle Button during a regeneration cycle will immediately advance the valve to the next cycle
step position and resume normal step timing.
4. Pushing the Up or Down Set Button during a regeneration cycle will adjust the time remaining in a regeneration
cycle step. Actual Regeneration Cycle Step programming will not be changed.

Control Operation (Cont’d.)
Control Operation During Programming
The control will only enter the Program Mode with the valve in Service and operating on line po wer. While in the
Program Mode the control will continue to operate normally monitoring water usage and keeping all displays up to date.
Control programming is stored in memory permanently with or without line or battery backup power.
Lockout Input Operation
The Lockout Arrow will turn on whenever a Lockout Signal is being received by the control. Any requests for
regeneration will be delayed until this signal is removed. Regeneration will then proceed normally.
Keypad Operation
Extra Cycle Button
Pushing this button will initiate a regeneration cycle independently of actual valve conditions.
1. With immediate regenerati on valves this extra regeneration would occur immediately.
2. With delayed regeneration valves this extra regeneration would occur at the set Regeneration Time. A regeneration
cycle can be forced to occur immediately by pushing and holding in this button for 5 seconds.
Program Button
This button is used by the installer to program those settings indicated on the front panel by red LEDs.
Up Set Button
This button is used to set the current time of day, adjust time remaining in a regeneration cycle step, and in valve
programming. The Up Arrow Button will increment a display setting.
Down Set Button
This button is used to set the current time of day, adjust time remaining in a regeneration cycle step, and in valve
programming. The Down Arrow Button will decrement a display setting.
Low Battery Indicator
When the control is operating on line power this red LED will turn on whenever the
used for memory backup needs to be replaced. The battery is stored inside the top cover. In the event of a power
outage, the battery will maintain current operating data for approximately 24 hours at maximum batt ery capacity.
