Installation Requirements
A level floor position ahead of piping into water heater.
Unit must be installed at least 10 feet ahead of the inlet to a water heater to prevent damage due to back-up hot water. A
thermal expansion tank is also recommended. Follow your local plumbing codes.
DO NOT install the unit in an area of direct sunlight or where freezing temperatures may occur!
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 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: Below installation is after the pressure tank.

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.
2. The filter material is shipped separately from the mineral tank with the exception of gravel. The 20# gravel is already
in the filter tank. The tank must be loaded with material after tank has been placed at the desired location.
A. Remove the tank cap from the media tank.
B. Use a cork or tape to place over top of distributor tube to prevent material from entering tube while filling.
C. Place media funnel provided 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. The required quantity & type of media is listed in the filter specifications.
F. After installing filter media, add the included pack of aeration balls.
G. After filling the tank with material, use a garden hose or several buckets to fill the tank with water.
Note: 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.
H. Remove funnel and clean filter media from tank threads.
I. Remove cork or tape from distributor tube.
J. Replace tank cap on mineral tank.
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.
- Drain Line Connection -
1. Pull out clip and remove drain line assembly located on the left side of control valve. Remove drain line hose elbow
and wrap threads with Teflon tape. Reinstall drain line hose elbow. Replace drain line assembly and reinstall clip.
Caution: Hand tighten only!
2. Install 1/2" I.D. drain line tubing (not included) from hose elbow 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.

- Electrical Connection -
1. Connect the power cord and plug power supply 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

Normal Operation
1. Home Display
- 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 Regeneration Day
Override Value until it reaches 1 day remaining.
- A Regeneration Cycle will then be initiated at the ne t designated regeneration time.
2. Battery Back-Up (Uses a standard 9-volt alkaline battery.)
- Installing the battery
- Features of Battery Back-Up
Maintains the Time of Day during power failures.
Notes: 1) During power failures, the display is turned off to conserve battery power. However, to confirm that the battery
is working, press either button and the display will turn on for five (5) seconds.
2) If power failure occurs while system is regenerating, the valve will motor to a shut off position to prevent
constant flow to drain. Note: 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 valve will return and finish the cycle where it
left off prior to the power interruption.
3) When used without battery back-up, the unit acts like a standard valve. When a power failure occurs, the unit
stops at its current point in the regeneration position and then restarts at that point when the power is restored.
However, the time will be offset by the increment of time the unit was without power.

backwash cycle occurs. If the Number of Days between ir Draw Cycles is set to
a higher number of days than the Number of Days between Backwash Cycles, it
will have no effect. In order to turn off all cycles, both the Days between Backwash

Set Up Procedures
1. Move the bypass valve slowly to the Service position or open the main valve and allow water to flow to the mineral
tank.
2. When the water stops flowing into the tank, open a treated water tap and allow air to be released from the lines. Allow
several minutes during this time to follow steps on valve for setting the time. Once time of day is set, go back to main
menu. Then close the tap. Open the bypass valve or main valve completely. The days for backwash and air draw are
already programmed.
Anytime media (other than very fine mineral on initial startup) is apparent in the service lines, it usually indicates one of
the following problems:
A. The unit is plumbed in backward allowing the media to be carried in the service line.
B. The distributor tube inside the tank is not seated inside the valve or is damaged in some way.
C. If the media flows to the drain during backwash, after a reasonable period of soaking, check the drain line flow
control to be sure that excessive water is not going to the drain allowing mineral to siphon out of the tank.
3. Hold down set/change button for five (5) seconds. (A “1” will appear), release and repeat. The unit will now enter
backwash. Allow the unit to perform an entire cycle. This will rinse media and charge up the air chamber.
4 Once unit is back in service, clean water will be available, approximately “60” minutes. Any water used during a
cycle will be untreated.
- Final Checkout -
1. Be certain that the bypass valve is in Service position or main valve is completely on.
2. Check electrical supply to be certain the cord is connected to an uninterrupted 115 volt outlet.
3. Be certain the warranty card is filled out and mailed in.
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.
