Congratulations on your purchase of a RainSoft water treatment

system!

This Owner’s Manual is designed to assist with the operation, main-

tenance, and installation of your water treatment system. It is our

sincere hope that this manual is clear, concise, and helpful to you as

a new owner.

Questions? If you have any questions regarding the installation,

operation, or servicing of this system, please contact your local

RainSoft Dealer. Your local RainSoft Dealer is familiar with your

particular water conditions, and is able to address your concerns

promptly and efficiently.

Application Limitations

pH: The influent water must be between 6.8 and 9.0.

Iron: Third party testing conducted at 3.7 ppm of ferrous (clear

water) iron. If iron is present, the pH should be below 8.5.

Iron Bacteria: If iron bacteria are present, frequent service may

occur and the life of the system may be limited. By properly control-

ling the iron bacteria with chlorine or other approved methods for

bacterial reduction, the system will function properly.

Hydrogen Sulfide: Third party testing conducted at 1.1 ppm.

Manganese: Third party testing conducted at 1.68 ppm at an

average pH of 8.6; amounts over 1.68 ppm may gradually prevent

iron removal. For optimum manganese reduction, the pH should be

between 8.0 and 9.0. If iron is also present, the pH should be below

8.5.

Organic Matter (Tannins): The presence of organics above 2.0

ppm may hinder the operation of the system.

Chlorine: The presence of chlorine in the raw water supply should

be limited to a maximum of 1.0 ppm.

Operational Specifications

Plumbing: 3/4to 11/4

Drain Line: 1/2

Water Pressure: 20 psi–120 psi (137.89 kPa–827.37 kPa)

Actual Influent Flow Rate: (Water available from well pump,

service inlet, etc.) The actual flow rate must exceed 5 gallons per

minute. Failure to backwash the system at a rate of 5 gallons per

minute (for 150 Models) or 9 gallons per minute (for 250 Models)

will inhibit the filter’s ability to perform as designed.

Service Flow Rates: See the data chart on page 4 for maximum

service flow rates.

Operating Temperatures: 40°F–100°F (4.4°C–37.8°C)

Electrical Requirements: A properly grounded, alternating current

supply (110 VAC 60 Hz or 230 VAC 50 Hz) is required for operation.

Bypass Valve: The manually operated bypass valve enables the

system to be isolated from the water service line for maintenance,

service, and outdoor water use. It also maintains the continuity of

the water supply when the system is disconnected.

Important Note: This system requires the

use of the supplied 24 VAC transformer.

Helpful Tip: The maximum service flow rate

is for continuous flow, not peak flow.

Important Note: Higher pH conditions may

cause the formation of colloidal iron, which

is very difficult to remove.

Important Note: The limitation for

Hydrogen Sulfide can vary depending on

overall water quality.

For water containing only Hydrogen

Sulfide without Iron or Manganese: Low

pH improves the conversion of Hydrogen

Sulfide by aeration. If you are using an acid

neutralizer for pH correction, we recom-

mend installing the neutralizer between

the air and filter tanks of the Oxytech

system. This will allow for the most effec-

tive conversion of Hydrogen Sulfide in the

air tank.

Existing Plumbing Conditions: Plumbing should be free from lime

and/or iron buildup. Piping that contains large amounts of lime

and/or iron should be replaced.

Additional Specifications

• Do not install this system where water is microbiologically unsafe or

of unknown quality without adequate disinfection before or after

the system.

• This system must be installed in accordance with all applicable state

Installation Instructions

1. Safety Precautions

• To prevent accidents/injuries, do not hoist the system over

your shoulder; use a hand truck.

• Do not lay the system on its side.

• Wear safety glasses and work gloves during installation and

service.

2. Test the Raw Water Supply

• Test the raw water supply to ensure it meets the “Application

Limitations” on page 3.

3. Check the Well Pump Flow Rate

• With no water running in the system, open a faucet and let the

water run. When the pump motor starts, note the time and

close the faucet. When the pump motor stops, record the time

in seconds.

• Run water into a measured container (pail with markings,

gallon jug, etc.) until the pump starts. Record the number of

gallons in the container.

• Divide the gallons of water in the container by the number of

seconds the pump ran. This number is your gallons per

second. (The number should be less than one.)

• To calculate the gallons per minute, multiply the gallons per

second by 60. Repeat this procedure at least three times to

obtain the average well pump flow rate.

4. Locate a Site for the System

• The installation site must have a level, smooth, and clean

surface (see Figure 1).

• The two tanks should be installed after the pressure tank and

as close to each other as practical.

• If the system is located outdoors, protect it from direct

sunlight; direct sunlight can damage the fiberglass and other

system components. If necessary, build a box or shed.

Important Note: The well pump flow rate

must exceed the recommended backwash

flow rate of 5 gallons per minute (150

Models) or 9 gallons per minute (250

Models) for the system to clean effectively.

Failure to properly backwash the system

will result in premature system failure.



Example: The water measurement is 6.5

gallons and the pump time is 40 seconds.

6.5 gallons/40 seconds = 0.1625 gallons per

second

0.1625 gallons per second X 60 seconds =

9.75 gallons per minute

For this example, the well pump flow rate is

9.75 gallons per minute.

Important Note: The system can only be

installed outdoors in climates that do not

reach freezing levels.

5. Fill the Filter Tank with Media

• Remove the cap plugs from both tanks.

• Pull up on the riser pipes and inspect the distributors. The filter

tank will have a screen distributor (see Figure 2) and the aeration

tank will have an open distributor (see Figure 2). WARNING! THE

RISER PIPES ARE NOT INTERCHANGEABLE.

• Close off the top of the filter tank riser pipe (see Helpful Tip).

• With the funnel provided, add fills 1– 4 to the filter tank (see

Figure 3). Before adding each fill, move the filter tank from side-

to-side to evenly distribute the media.

6. Install the Control Valves

• Lubricate the riser pipe O-rings and tank O-rings with Dow

111 silicone-based lubricant or equivalent.

• Align the filter control valve with the screen distributor riser

pipe (see Figure 4). Push down on the filter control valve and

continue to turn it clockwise until the valve O-ring seals

against the filter tank. WARNING! THE CONTROL VALVES ARE

NOT INTERCHANGEABLE.

• Align the aeration control valve with the open distributor riser

pipe (see Figure 4). Push down on the aeration control valve and

continue to turn it clockwise until the valve O-ring seals

against the aeration tank. WARNING! THE CONTROL VALVES

ARE NOT INTERCHANGEABLE.

7. Turn Off the Water and Drain the Plumbing

• Turn off the water at the meter or the pressure tank.

• Open all faucets and flush the toilets. The water will drain out

of the lowest faucet or outlet and air will enter the plumbing

system.

8. Bypass the Outside Faucet(s)

• Install plumbing pipes to bypass the outside faucet(s). If the

plumbing is not accessible, provide an untreated hose bib on

the inlet pipe.

9. Install the Check Valve

• Install the supplied 1check valve on the raw water supply

feeding the aeration tank (see Figures 5.1 & 5.2). The check valve

must be installed in vertical, upflow position with a minimum

12water column above the check valve (see Figures 5.1 & 5.2).

10. Connect the Plumbing

• Connect the check valve outlet to the aeration tank inlet (see

Figure 6).

• Connect the aeration tank outlet to the filter tank inlet (see

Figure 6). Use 1diameter pipe between the aeration tank and

filter tank.

• Connect the filter tank outlet to the house plumbing (see Figure 6).

11. Bypass Both Systems

• Move the bypass valve handles to the bypass position. The

bypass valve handles should be perpendicular to the pipes

(see Figure 7).

Helpful Tips: Do not sweat pipes with water

in them or while attached to the system;

steam will damage the plastic parts in the

valves.

Do not point the soldering torch directly at

the tanks or valves. These composite mate-

rials will last a lifetime, but cannot with-

stand the intense heat from a torch.

Avoid short connections of pipe between

the system outlet and the water heater

inlet. If you can’t avoid a short connection,

move the system to another location. As a

last resort, install a heat trap or check

valve. If this causes “water hammer”, install

a “water hammer” suppressor.
