Setup
Unpacking and Inspection
Check the WATER DOCTORS system components for damage or missing parts.
Where to Install the Softener
Consider the following points when determining where to install the water softener:
Place the WATER DOCTORS system as close as possible to a sewer drain.
Do not install the softener where it would block access to the water heater, or access to the main water
shutoff, water meter, or electrical panels.
Keep outside faucets on hard water to save soft water and salt.
Install the softener in a place where water damage is least likely to occur if a leak develops.
A 120V electrical outlet is needed to plug in the transformer. If the outlet is remote (up to 100 feet), use 18
gauge wire to connect.
Always connect the WATER DOCTORS system to the main water supply pipe before the water heater.
Install the WATER DOCTORS system where it will not be subject to temperatures outside of the limits
stated in the Specification section or to direct sunlight.
Hardness Setting
Municipal Water
WATER DOCTORS recommends that you call your local water company to determine your water hardness in
grains per gallon and iron in mg/l (or ppm).
Well Water
WATER DOCTORS recommends that you have your water tested professionally for accurate hardness and iron
content.

Installation
1. Turn off gas or electric supply to the water heater.
2. Turn off the water supply to pipes to be cut and drain the house water pipes.
3. Open both hot and cold faucets.
4. Move the softener assembly into installation position.
Be sure the installation surface is level and smooth.
5. Plumb IN and OUT connections to and from softener.
Be sure the incoming hard water supply is directed to the INLET port of the valve.
The valve body of the control is marked with arrows indicating the proper flow direction.
Connections are illustrated below.
Figure 2
CAUTION: If making a soldered copper installation, do all sweat soldering before connecting pipes to the bypass
valve. Torch heat will damage plastic parts.
CAUTION: When turning threaded pipe fittings onto plastic fittings, use care not to cross-thread.
CAUTION: Use Teflon tape on all external pipe threads. Do not use pipe joint compound.
CAUTION: Support inlet and outlet plumbing in some manner (use pipe hangers) to keep the weight off of the valve
fittings.
Perform steps 6-9 to install flexible drain hose.
Skip to step 10 to install rigid drain pipe.
6. Find barbed hose fitting in small parts kit. Attach barbed hose fitting to the 1/2" male NPT drain outlet.
7. Cut the length of the hose in half. One section will be used as a valve drain hose. The remaining section will
be used as an overflow hose in Step 11.

Use Step 10 to install rigid drain pipe.
10. To adapt a rigid drain pipe to the WATER DOCTORS system, do not attach barbed hose fitting to valve.
Instead, plumb rigid tubing directly to the 1/2" male NPT drain fitting.
11. Take the other half of the cut hose and attach it to the overflow adapter elbow located on the side of the
brine tank. Use a hose clamp to hold it in place. Locate the other end of the hose at the drain point as
shown in Figure 3.
12. Fully open two (2) cold (soft) water faucets near the water softener.
13. Place bypass valve in "bypass" position as shown in figure 4.
Figure 4
14. Fully open the house main water shutoff valve. Observe a steady flow from both faucets opened earlier.
15. Slowly, turn bypass valve back in the "service" position. Keep soft water faucets open.
16. After about 3 minutes, open a HOT water faucet for one (1) minute, or until all air is expelled, then close.
NOTE: If water appears cloudy or has salty taste, run the water for several more minutes, or until clear.
17. Close all water faucets.
18. Check plumbing work for leaks and fix immediately if any are found.
19. Remove the brine tank cover and add water into the tank. Although the material used in the manufacturing
of this water softener will not contaminate your water supply, the softener could become contaminated
during shipment and installation. The media inside the resin tank may also have become disturbed during
shipping. The following procedure will help re-position the media, sanitize, flush and condition your water
softener:
a) Add 1-1/2 ounces of common household bleach to the water in the cabinet (brine tank).
b) Following the directions in the 5800 LXT/SXT Service Manual. Manually advance the softener through
each step of regeneration pausing for 10 minutes in each cycle except the Fill cycle (see step c.).
c) See the enclosed Water Softener Performance Data Sheet for the Fill cycle time associated with your
model.
d) Repeat step 19a and 19c after any service has been performed on your water softener.

Softener Operation
As water enters the softener, it passes over a resin bed in a special tank. The resin consists of tiny beads of a
plastic called styrene. These beads attract and hold sodium ions and exchange the sodium for hardness ions
when encountered. Over time, the resin becomes saturated with hardness ions and no longer removes
hardness materials. The softener goes into a "regeneration" to flush hardness materials to the drain and refresh
the resin with sodium. Regeneration is typically programmed to take place in the middle of the night when little
or no water is in use.
Regeneration consists of four cycles:
1. Brine Draw / Slow Rinse Position
Brine Draw is the process in which brine is drawn out of the brine cabinet and passed through the resin in a
downward direction. This rinses the resin and large amounts of sodium ions replace the hardness ions
accumulated during service. Slow Rinse. After brine is completely removed from the brine cabinet into the
resin tank the brine valve closes. Water replaces any remaining brine from the resin, flushing hardness ions
removed from the resin to drain.
2. Backwash Position
Backwash is a rapid upward flow of water that loosens the resin bed and flushes iron particles, dirt and
sediments filtered in the bed out to the drain.
3. Fast Rinse Position
Fast Rinse is a fast flow of water down through the resin tank that follows a Backwash. This flushes all
remaining brine from the tank and packs the resin bed for softening efficiency.
4. Brine Fill
Brine is water saturated with large amounts of a salt (sodium chloride). During brine fill, water flows into the salt
storage area after each regeneration and dissolves salt. During the regeneration process, hardness ions on the
resin beads are replaced or exchanged for sodium ions from the brine solution.
5. Service
When the softener is in the Service Position, water flows through the system removing hardness minerals from
your water.

Service
Cleaning Iron Out of the Water Softening System
The WATER DOCTORS system is designed to remove minerals like calcium and magnesium from household
water. WATER DOCTORS recommends periodic resin bed cleaning if your iron rating is high. Clean the bed at
least every six months, or more if iron appears in the soft water between cleanings.
Checking for a Salt Bridge
A hard crust or "Salt Bridge" can form in the lower half of the salt storage tank. This can be deceiving because
the tank will appear to have plenty of salt, but underneath, salt has hardened and when the system regenerates,
water cannot quite reach this level to be made into brine (water and salt).
Breaking a Salt Bridge
Take a wooden broom handle and carefully push it down into the salt, working it up and down. If the tool strikes
a hard object (be sure it's not the bottom or sides of the tank), it's probably a salt bridge. Carefully break the
bridge with the broom handle. Do not pound on the walls of the tank.
NOTE: Salt bridges are typically caused by high humidity or using the wrong kind of salt. In humid areas it is
best to fill with less salt, more often. Use only nugget, pellet or coarse solar salt with a purity of 99.5% or higher.
DO NOT use rock, block, granulated, and ice cream-making salts, or salt with iron-removing additives.
Cleaning the Injector and Screen
1) Turn off water supply to conditioner:
a) If the conditioner installation has a “three valve” by-pass system, first open the valve in the bypass line, then
close the valves at the conditioner inlet and outlet.
b) If the conditioner has an integral by-pass valve, put it in the by-pass position.
c) If there is only a shut-off valve near the conditioner inlet, close it.
2) Relieve water pressure in the conditioner by stepping the control into the backwash position momentarily. Return
the control to the service position.
3) Unplug electrical cord from outlet.
4) Remove the two injector cap mounting screws.
5) To replace injector and screen.
a) Pull the screen and injector throat/nozzle assembly out of the valve body.
b) Insert a new injector throat/nozzle assembly, be sure they are sealed tightly. Install a new screen.
c) Apply silicone lubricant to new injector cap seal.
6) Replace injector cap with two mounting screws.
7) Tighten screws.
8) Return by-pass or inlet valving to normal service position. Water pressure should now be applied to the
conditioner, and any by-pass line shut off.
9) Check for leaks at all seal areas. Check drain seal with the control in the backwash position.
10) Plug electrical cord into outlet.
11) Set time of day and cycle the control valve manually to assure proper function. Make sure control valve is
returned to the service position.
12) Make sure there is enough salt in the brine tank.
13) Start regeneration cycle manually if water is hard.
