Installation
Installation Requirements
• A level floor position ahead of piping into water heater.
• Unit must be installed at least 10’ ahead of the inlet to a water heater to prevent damage due to
back-up of hot water.
• DO NOT install the unit in an area of direct sunlight or where freezing temperatures may occur!
(See Installation Diagrams for proper placement and plumbing connections.)
• A level floor position ahead of piping into water heater.
• Unit must be installed at least 10’ ahead of the inlet to a water heater to prevent damage due to
back-up of hot water.
• DO NOT install the unit in an area of direct sunlight or where freezing temperatures may occur!
(See Installation Diagrams for proper placement and plumbing connections.)
Nitrate Filter Location / Other Requirements
• Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
• Check for distance and proper drain installation (e.g. floor drain, washing machine standpipe).
• Determine type and size of piping required for nitrate filter connection (e.g. copper, galvanized, PVC plastic).
Note: If household plumbing is galvanized and you intend to make the installation with copper (or vice versa), obtain
di-electric unions to prevent dissimilar metal corrosion.
Note: Where the drain line is elevated above the control valve or exceeds 20 feet in length to reach the drain, use 3/4”
I.D. drain line tubing instead of 1/2” I.D. Drain line tubing is not included.
Caution: If sweat soldering copper pipe (remember to always use lead free solder and flux), cover yoke and bypass valve
with wet rags to prevent heat damage to connections and control valve! If using PVC or plastic pipe, primers and
solvent cements specifically recommended for use with potable water are required.
Note: All plumbing lines not requiring “soft” water should be connected “upstream” of the softener.
(See Typical Installation Diagrams)
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. Position filter at desired location for installation. (See Installation Diagram.)
2. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
3. Cut main line and install appropriate elbows and extensions. Inlet and outlet connections on the control valve are
3/4” FNPT.
Note: An optional 1” FNPT is available.
Caution: Raised arrows located on the sides of control valve body and bypass valve indicate proper direction of water
flow. Install inlet and outlet piping in direction of arrows.
4. Rotate handle on bypass valve to the bypass position
5. Turn the main supply line on to restore water service to the home.
6. OPEN nearest faucet to evacuate air and repressurize plumbing lines.
7. Check for leaks!
5
SIGNATURE 2 SERIES
Installation
1. Pull out clip and remove drain line assembly located on the left side of control valve. Remove drain line hose barb and
wrap threads with Teflon tape. Reinstall drain line hose barb. Caution: Hand tighten only!! Replace drain line assembly
and reinstall clip.
2. Install 1/2" I.D. drain line tubing (not included) from hose barb to an open drain. A 4” gap between the end of the drain
line and the open drain is required to prevent waste water backflow. Keep the drain line as short as possible. An
overhead drain line can be used if necessary, but should discharge below the control valve. A syphon trap (taped loop)
at the outlet of the drain line is advisable to keep the drain line full and assure correct flow during regeneration. Elbows
or other fittings must be kept at a bare minimum.
Note: Where the drain line is elevated above the control valve or exceeds 20’ in length, 3/4" I.D. drain line tubing should
be used.
1. Position brine tank on smooth, level surface near the nitrate filter resin tank. If necessary, the brine tank can be placed
at a higher level than the resin tank, but never at a lower level.
2. Install one end of 3/8” O.D. by 1/4" I.D. brine line tubing (included with unit) to compression fitting located on left side of
control valve.
3. Remove brine tank cover.
4. Remove cap from brine well.
5. Insert opposite end of brine line through outer hole in brine tank.
6. Connect brine line to push fitting on safety brine valve located inside brine well.
7. Install 1/2" I.D. drain line tubing (not included) to the overflow fitting on brine tank located just below the brine line.
8. Run the opposite end of brine tank drain line to a suitable drain.
Drain Line Connection
Brine Line and Overflow Connection
Note: The brine tank drain line is gravity flow and must discharge below the overflow fitting.
Caution: Do not “TEE” to the main drain line from control valve.
Notice: The brine overflow is provided as a back-up in the event the safety float shut-off should fail, allowing the brine
tank to overfill. This drain connection would then carry the excess water to the drain and prevent flooding of the
floor. Therefore, no liability will or can be assumed by the manufacturer of the nitrate filter should this occur.
Electrical Connection
1. Connect the power supply to the control valve and plug into a 115 volt / 60 Hz receptacle.
Note: Do not plug into an outlet controlled by a wall switch or pull chain that could inadvertently be turned off.
Installing Battery Back-Up
1. Remove the valve cover.
2. Install a 9 volt battery.
Pressurizing The System
1.Slowly rotate handle of the bypass valve to the SERVICE position.
2.Open the nearest faucet to evacuate air from plumbing lines.
3. Check for leaks!

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
NO3 and multiply by 50.1
Example : (50 ppm NO3/62) x 50.1 = 40.4 ppm as CaCO3
Sulfate Divide ppm (mg/l) of Sulfate by 48
(SO4) and multiply by 50.1
Example : (75 ppm SO4/48) x 50.1 = 78.28 ppm as CaCo3
Step 2: Calculate the Nitrate / Sulfate ration (as CaCO3).
NO3 (Nitrate) = Ratio
NO3 (Nitrate) + SO4 (Sulfate)
Example : 40.4 ppm = .34 Ratio
40.4 ppm + 78.28 ppm
Step 3: Calculate the operating capacity per cubic foot of resin at 12 lbs. per cubic foot salting (factory setting).
Figure 3 OPERATING CAPACITY
Note: DO NOT REDUCE SALT BELOW THIS LEVEL!
Operating Capacity = 8,500 grain / cu. ft. of media
7
SIGNATURE 2 SERIES
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.
NO3 ppm as CaCO3 = grains of Nitrate
17.1
Example: 40.4 ppm NO3 as CaCO3 = 2.36 grains (or 3 grains)
17.1
Step 6: Enter meter programming mode and set system capacity (items) to answer in step 4.
Example: 12,750 grains capacity
Step 7: Program the Signature Series Control Valve for grains of nitrate calculated in step 5.
Example: 3 grains (always round the number up)
- Control Valve Operation -
1. Advance control valve to BACKWASH (cycle 1) position and allow water to run to drain for 3 to 4 minutes.
Warning : Close valve on bypass prior to selecting the backwash position. After backwash position has been
established, slightly open bypass to evacuate air from the media tank. Fully open valve when all air
is depleted. This procedure will prevent media from being uplifted into control valve.
2. Advance control valve to BRINE REFILL (cycle 4) position and allow the brine tank to fill just over the salt grid plate.
3. Advance control valve to BRINE & RINSE (cycle 2) and allow the control valve to draw water from the brine tank until it
stops. If no draw is observed, check tightness of brine line compression fittings.
4. Advance control valve to RAPID RINSE (cycle 3) position and let run to drain for 3 - 4 minutes.
5. Advance control valve to BRINE TANK REFILL (cycle 4) position and allow the control valve to automatically fill the
brine tank.
Note : Control valve will advance to service position automatically.

SIGNATURE 2 SERIES
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.
A pellet type salt is recommended, although any high quality water softener salt (such as solar salt) will suffice. The salt
level will decrease after each regeneration cycle. Consequently, the brine tank will need to be checked and replenished
periodically.
1. Fill the brine tank with water softener salt as described above. This will be approximately 250 pounds of salt.
Warning: Do not fill above level of the brine well.
2. Replace brine tank lid.
Final Check
1. Be certain the bypass valve is in the SERVICE position.
2. Make sure the power supply is connected to an uninterrupted 115 volt outlet.
3. Check that the time of day is set.
4. Double check regeneration schedule.
5. Make final check for leaks!
6. Fill out and mail warranty card.
7. Leave all manuals with unit.
Operation, Care and Cleaning
When the inlet/outlet knobs on the bypass valve are in the SERVICE position (position of bypass knobs are parallel to the
inlet/outlet piping), water is directed through the nitrate filter. Water may be bypassed by turning the inlet/outlet knobs to
the bypass position (position of bypass knobs are at right angles to inlet/outlet piping). Water to the home will bypass the
nitrate filter and be untreated.
You should manually bypass the nitrate filter if:
1. The outside lines do not bypass the nitrate filter and water is to be used for lawn sprinkling or other similar uses.
2. Servicing the nitrate filter.
3. A water leak from the nitrate filter is evident.
4. Shock treating water well and piping with chlorine or other disinfectant.
Extra Regeneration
If soft water demands are usually heavy, an extra regeneration can be initiated manually:
To Skip A Regeneration
1. For vacations, or extended periods of absence, the power supply can be disconnected from the control valve.
2. Upon return, plug in cord and reset the time of day, if 9 volt battery was not installed. If battery was installed, replace
battery.

SIGNATURE 2 SERIES
Control Valve Start Up
- Programming The Control Valve For “MS” Units -
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. Use this COMPENSATED HARDNESS level when programming the regeneration frequency.
1. Set regeneration day override if other than (7) days is desired. (This is particularly useful when iron is being treated to
prevent fouling of the resin.)
2. Set regeneration time, if other than 2:00 a.m. is desired.
Note : Salt settings are pre-set at the factory for the maximum shown on the capacity charts.
Warning : Do not reduce salt settings below 9 lbs. as the water level in the brine tank will not reach the grid plate.

Normal Operation
1. Home Display
a. Time Clock Softeners -Alternates between the display of Time of Day and Number of Days until the Next
Regeneration.
- Days Remaining until the Next Regeneration will count down from the entered value until it reaches
1 day remaining.
- A Regeneration Cycle will then be initiated at the next designated regeneration time.
b. 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:
• During power failures, the battery will maintain the time of day as long as the battery has power. The
display is turned off to conserve battery power during this time. To confirm that the battery is working,
press either button and the display will turn on for five (5) seconds.
• If power failure occurs while system is regenerating, the Signature 2 will motor to a shut off position
to prevent constant flow to drain. Depending upon system pressure and other factors, it is possible to
observe a reduced flow to drain during this step. After power is restored, the Signature 2 will return
and finish the cycle where it left off prior to the power interruption.
• When used without battery back-up, during a power failure, the unit stops at its current point in the
regeneration position and then restarts at that point when the power is restored. The time will be
offset by the increment of time the unit was without power, so it is necessary to reset the time of day
on the unit. No other system will be affected.
Starting Extra Regeneration Cycle
1. To Start Delayed Extra Cycle Example [ 1 ]
- If Days Remaining Until Next Regeneration does not read ‘1’, press and hold the Set/Change button for 3
seconds until the display reads ‘1’, or ‘0000’ on metered models.
- Regeneration cycle will initiate at the next designated regeneration time.
2. To start Immediate Extra Cycle First complete above step.
- With Days Remaining Until Next Regeneration at ‘1’ or ‘0000’,
- Press and hold the Set/Change button.
- After 3 seconds, the regeneration cycle will begin.
3. To Fast Cycle thru regeneration First complete above 2 steps.
Note: Press and hold the Set/Change button for 3 seconds to advance to the next cycle step. Fast Cycle is not
necessary unless desired to manually step through each cycle step. (Repeat until valve returns to the home

Utilizing Bluetooth Control
To take advantage of the Bluetooth interface this feature must be set up on a compatible Bluetooth enabled smart phones
or tablets.
Note: Valves with a revision number greater or equal to “C2.00” are only compatible with Bluetooth 4.0+ (a.k.a.
Bluetooth LE) Smartphones and tablets. If you have an Android or Apple device with a compatible Bluetooth
radio it can be used to connect to the valve. Valves with a revision number less than “C2.00” are only compatible
with Android devices and these valves use a Bluetooth 2.0 radio. In the rest of this section valves with a revision
number greater or equal to “C2.00” will be referred to as BTLE, valves with a revision number less than “C2.00”
will be referred to as BT.
(The firmware revision of the valve can be viewed on the valve display for 2 seconds after the valve is powered up.)
Unfortunately due to changing Bluetooth and Tablet / Phone manufacturing standards, not all tablets and smart phones
are compatible with all valve versions. In general, the below table should guide you in compatibility.
Android Device with BT 4.0+ Yes Yes
Android Device with older BT Yes No
Apple Device with BT 4.0+ No Yes

1. Download and install the Legacy View app from the Google Play Store, Apple App Store or
www.ChandlerSystemsInc.com
2. If your valve revision is a BTLE valve you can skip this step. Otherwise, if it is a BT valve the following steps must
be followed to pair your smart phone or tablet to the control valve.
• Open the settings menu on your smart phone or tablet and click on Bluetooth.
• Look for the softener or filter valve you want to connect to under the list of available Bluetooth devices.
• Select the device and pair (Default password is: 1234)
3. Open the Legacy View app
• Choose a valve device at any time from the list of available devices to connect to by clicking on it.
• If the valve you want to connect to doesn’t show up, or there is a problem connecting to a device you can
press the “Scan for Devices” button or the Legacy View logo at any time to refresh the list and start the
process over.
• If the valve device is a BTLE valve and it has a password other than the default password, the first time you
connect to it the app will ask you to enter the password. After entering it the first time you should not need to
enter it again unless it changes.
4. BTLE Valve devices can be updated by the App. When the app is updated from the Google Play Store or the
Apple App Store, it may contain an updated firmware program for the valve devices. These updates could contain
new features or operational improvements. It is up to the user to allow these updates to be sent to the valve device.
Uploading a new program takes approximately 1 minute.
