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.)
Filter Media Installation

6
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.
• All plumbing lines not requiring “soft” water should be connected “upstream” of the softener, if installed. (See Typical
Installation Diagrams.)
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.
Installation

Installation Procedure
- Water Supply Connection 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 raw water to be manually routed around the filter.
1. Position filter at desired location for installation. If a water softener is to be installed, the filter should be positioned first
and then the softener. (See Installation Diagrams.)
2. The filter material is shipped separately from the mineral tank. The tank must be loaded with material after tank has
been placed at the desired location.
A. Remove the control valve by unscrewing from the tank. (Do not fill through dome hole, if installed.)
B. Use cap provided to place over top of distributor tube to prevent material from entering tube while filling.
C. Place media funnel (part # U-1006) in hole on top of tank.
D. Pour several gallons of water in the tank. (Fill tank about 1/3 full.)
E. Pour in the required filter media. No gravel is required. The required quantity of media is listed in the filter
specifications.
Note: If rebedding an existing unit and the system utilizes a standard tube & basket style distributor, a
“D” gravel underbedding will be required.
F. After filling the tank with material, use a garden hose or several buckets to fill the tank with water.
This will permit the filtering media to become soaked while preparing the installation and will prevent the control
valve from being plugged with floating material on initial backwash.
G. Remove funnel and clean filter media from tank threads.
H. Remove cap from distributor tube.
I. Replace control valve on mineral tank. Do not use Teflon tape or paste on valve threads, as the valve to
tank o-ring seals this joint.
Caution: Be extremely careful to position distributor tube into control valve distributor tube pilot hole.
3. Turn OFF main water supply and OPEN nearest faucet to relieve pressure.
4. Cut main line and install appropriate elbows and extensions.
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. It is recommended that a vacuum breaker be
installed on the inlet plumbing.

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.
- Pressurizing The System -
2. Slowly rotate handle of the bypass valve to the SERVICE position.
3. Open the nearest faucet to evacuate air from plumbing lines.
4. Check for leaks! If water is observed leaking from bypass, o-rings on valve body may not be seated properly. Exercise
bypass valve.
5. After air is evacuated from plumbing lines, turn off faucet.
- Initial 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 handle on bypass prior to selecting the backwash position. After backwash position has been
established, slightly open valve on bypass to evacuate air from the media tank. Fully open bypass valve
when all air is depleted. This procedure will prevent media form being uplifted into control valve.
2. Advance control valve to RAPID RINSE (cycle 3) position and allow water to run to drain for 3 to 4 minutes.
3. Advance control valve to SERVICE (cycle 0) position.

- Drain Line Connection -
1. The drain line flow control assembly is pre-assembled for your convenience. Should you choose to hard plumb the
drain line, please remove the barb fitting. The flow control housing can be removed by removing the clip and pulling
straight out on housing.
Note: When re-installing the drain line flow control housing, be sure you hear and feel the O-Ring pop into place before
inserting the clip.
2. Install 1/2” I.D. drain line tubing (not included) from hose barb to an open drain. A 4” gap between 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 backwash. 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 feet in length, 3/4” I.D. drain line tubing
should be used.

3. REGISTER YOUR PRODUCT at www.watersoftinc.com
4. Leave this manual with the homeowner.
Important Notice - The plumbing system, piping, pressure tank, hot water tanks, softeners, etc. that have been exposed
to iron bearing water may need to be cleaned of the precipitated iron that has been collected in them or iron bleed thru
may be a problem. We suggest all tanks be drained and flushed thoroughly.
- Programming The Control Valve -
1. Set time of day.
2. Set a.m. or p.m.
3. Set number of days between backwash. (This generally will be every 4 to 6 days.)
1. Set regeneration time if other than 12:00 a.m. is desired.

Normal Operation
1. Home Display
a. Alternates between the display of Time of Day and Number of Days until the Next Backwash.
(Metered Softeners will alternate between time of days and gallons remaining until next regeneration)
- Days Remaining until the Next Backwash will count down from the entered value until it reaches
1 day remaining.
- A Backwash Cycle will then be initiated at the next designated regeneration time.
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 Isobar 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 Isobar
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.
