Installation and

Start-Up Procedures

Each water conditioner includes 8’ of drain line.
1. Placement
Place your appliance in desired location. Turn off electricity and water

supply to water heater. Make sure inlet/outlet and drain connections

meet the applicable local codes. Check arrows on valve to be sure

water flows in proper direction.
See Figures 1, 2, & 3
CAUTION: DO NOT PLUMB APPLIANCE IN BACKWARD.
2. Connecting Water Lines
Lift and remove the valve cover. Attach the water lines to the in and

out connections. Do not over tighten connections on the plastic

threads. Check inlet connection and outlet connection to be certain

water flows in the proper direction. (As you face the front of the

appliance, the inlet is on the left and the outlet is on the right.) See

Figure 2
3. Drain Line
The drain line must be a minimum of

⁄

" I.D. tubing and should make

the shortest run to a suitable drain. The drain line may be elevated

up to 8 feet from the discharge on the appliance as long as the water

pressure in your system is 40 psi or more. If drain line is 25’ or lon-

ger, increase drain line to

⁄

" I.D. Also, the end of the drain line must

be equal in height or lower than the control valve. See Figure 1.
4. Flushing
Before placing your appliance in service, it is very important to flush

the cold water lines of any debris. Turn on water supply, open the

nearest cold water tap and let the water run for 2 to 3 minutes until

the water flows clear. Then put the by-pass in the Service position.

See Figures 4 through 6.
5. Check Leaks
Close faucet and check for leaks. If leaks are found, turn off main

water supply and open the nearest cold water faucet to depressurize

lines. Close faucet to eliminate siphoning action. Repair leaks. Turn

on water supply and electricity to water heater.
Place the bypass valve in the Service position. See Figure 6.
6. Connect Overflow Line
The overflow line is used to direct excess water to a floor drain if the

brine tank fills with too much water, or the appliance malfunctions.

The overflow line must end at a drain that is at least 3" lower than the

bottom of the overflow fitting. It is a gravity line and cannot be run

overhead. See Figure 7.

7. Complete The Installation
Open a cold water tap and allow the appliance to flush for 20

minutes or until approximately 72 gallons has passed through the

appliance per NSF requirements.
8. Plug In Transformer
See Figure 8.
9. Water Testing
The water conditioner, like any other appliance, requires correct

installation and setting for optimum performance. To ensure proper

settings, you need to obtain an accurate water test.
Do this as follows:
For municipally supplied or “City” water, call your water utility compa-

ny. Ask them the hardness, iron content and pH levels of your water.
For well water, have a sample of your untreated water tested for

hardness, iron and pH. To find a facility to test your water sample,

check your Yellow Pages under Water Analysis or Water Testing.
If you feel you have an abnormal amount of iron, be sure to use salt

with an iron-cleaning additive.
10. Adding Water & Salt
Be sure to remove any packaging or installation materials before

adding salt. Next, add no more than 3 gallons of water to the brine

cabinet. Then add salt to the brine cabinet, wait 2 hours then push

the REGENERATE button and hold for 5 seconds. A regeneration

cycle will begin and continue for approximately 27 minutes. After the

first regeneration, your appliance will automatically refill the correct

amount of water in the brine cabinet. See Figure 9.
11. Refill Salt
Refill Salt when the salt level drops below the water level in the brine

cabinet. Always keep salt above water level. See Figure 9.
CAUTION! Failure to install, operate and maintain your water

treatment appliance as instructed will VOID the product limited

warranty.
