Purifier for
Concrete Pools
Operating Manual
We ask you to take the time
to get familiar with this manual.
We believe the more you know, the more enjoyable and healthy your
family’s swimming experience will be – and the more you will reduce the
time, effort and cost of maintaining your pool. Pool owners who switch
from chemical programs to the Nature2purification technology spend
less time maintaining their pools.
Every pool has its own characteristics of water type, amount of sunlight,
etc. Discuss with your dealer the right "recipe" of water management to fit
the particular circumstances of your pool and geographic climate.
Remember, your authorized Nature2dealer can provide professional
advice and service.

1 Installation
If you decide to install the Nature2Purifier yourself, follow these instructions. The
letters in parentheses refer to a diagram on page 5 titled Replacing the Nature2
Purifier Cartridge.
This model purifier has been equipped with an automatic flow-control device,
designed to properly regulate the correct amount of water through the cartridge.
Under normal pump and filter pressure conditions on in-ground pool systems, the
flow rate to the inlet side of the purifier is 114 to 454 L/min.
Important: : If your pump system is designed to produce flow rates greater than
303 L/min, you should remove the orange flow control diaphragm (H) from the
vessel prior to installation. If your pump system is designed to produce flow rates
greater than 454 L/min or if plumbing is greater than 51 mm, then your purifier
must be installed in a bypass configuration (see page 5).
Installation
1 Decide where to install the Nature2Purifier. It should be installed:
•on a concrete slab to support the weight of the vessel,
• after the filter on the main return to the pool,
• before or after the heater,
• before any chemical dispenser or the discharge of an off-line
chemical dispenser.
2Locate the 51 mm socket inlet (F) and outlet (J) connections on the
purifier.
3 Connect the outlet from the filter to the purifier's inlet port (F) with
standard 51 mm PVC Schedule 40" pipe*; secure the connection with a pipe glue
that is compatible with PVC.
4Connect the purifier's outlet port (J) to the pool's return line with
the same type of PVC pipe*; secure the connection with the pipe glue.
5 Allow sufficient time for the glue to dry.
6 Screw on the cap (A) until it is snug. Do not overtighten the cap. Check that
all connections are secure.
Important: Do not install the Nature2Cartridge (E) yet.
7 Start the pump, check for leaks and repair any leaks you find.
8Proceed with Start-Up instructions.
*The Nature2Purifier can be reduced to accommodate 38 mm plumbing by
reducing bushings. These bushings will have no effect on the operation of the
purifier.
2
Bypass Installation
This 51 mm (2 in) Nature2Purifier system may need to be installed in bypass to
the filtration system if plumbing size is greater than 51 mm (2 in) diameter or if
flow rates are greater than 454 L/min.
If the Nature2Purifier is to be installed below the water level of the pool,
precautions must be taken to prevent the pool from draining during installation
and during cartridge change. Valves should be installed to isolate the system
during these situations.
All PVC fittings must be attached to the Nature2base using standard PVC cement.
The purifier should be set on a firm base.
The Nature2Purifier is installed on a bypass loop after the filter and always before
a chemical dispenser, if equipped, as shown below.
To create the bypass:
1 Install a “T” in the return line to allow water to divert to the Nature2
Purifier. This “T” is then connected to the inlet of the purifier.
2 Install a control valve in the return line after the first “T” and before the
second “T”
.
3Fully open any valves (including the control valve) that were closed
to isolate the purifier.
4 Start the pump allowing water to pass through the newly plumbed system.
The control valve in the return line between the two “T”s will control the flow
through the purifier.
Note: For flows in excess of 454 L/min with the Nature2in bypass, do not exceed
a 10.3 kPa increase in filter backpressure. Once 10.3 kPa is reached in this
situation the flow is correct through the purifier.
5Check the purifier for leaks and fix or replace any fittings.
6Follow the start up procedures.

2 Balance the Water
To find out if your pool water is balanced: • take a water sample to your dealer to be tested regularly, or • ask your dealer to recommend a pool test kit for water balance.
Element: pH If it’s too low: The surface of your pool can become etched. How to fix: Add pH increaser.
Range: 7.2-7.8 Metal parts in the pump and plumbing will corrode.
If it’s too high: “Scale” forms on the surface of your pool. How to fix: Add pH decreaser.
The water can become cloudy.
"Scale" forms on your pool equipment.
Element: Calcium Hardness If it’s too low: Water is less stable. How to fix: Add calcium hardness increaser.
Range: 200-300 ppm In plaster pools, the calcium is taken out of the plaster,
causing the surface to deteriorate.
If it’s too high: Rough, discolored deposits (“scale”) will form on the How to fix: Drain or dilute the pool water.
pool surface and inside pool equipment. Consult your dealer.
Element: Total Alkalinity If it’s too low: It provides no buffer so that you constantly get fluctuating How to fix: Use an alkalinity increaser.
Range: 80-120 ppm pH readings, which can damage equipment and pool surfaces.
If it’s too high: White deposits (“scale”) form on the tile line. How to fix: Add acid to bring alkalinity down.
The plaster on pool surface becomes rough or discolored.
The water becomes cloudy or milky white.
3 Start Up
Before starting up a new Nature2Cartridge, clean debris and algae out of the pool and equipment.
Important: Do not install the new cartridge until the pool water is chemically balanced.
1 Balance pool water before installing purifier cartridge.
•pH 7.2-7.8
• Calcium hardness 200-300 ppm
• Total alkalinity 80-120 ppm
Consult your Nature2Dealer for specific water balance instructions.
2 Install the cartridge after water is balanced.
3 Shock the pool to burn off contaminants and to activate the cartridge. Follow label instructions of shock product being used.
4Run the circulating pump either:
•24 hours a day for 4 days, maintaining 1-3 ppm free available chlorine, or
•6 hours a day for 14 days, maintaining 1-3 ppm free available chlorine.
5Let free available chlorine residual drop but not below a minimum of 0.6 ppm once start-up period is completed.
Low-Chlorine Recipe
(0.6 ppm free available chlorine minimum)
Ingredients:
• Nature2Purifier
•Chlorine granules, tablets, liquid or generator
•pH and total alkalinity adjusting chemicals
• Calcium hardness increaser, if needed
•Water test kit
• Cyanuric acid
Once the 4-day or 14-day start-up period is done, allow the free available chlorine residual to drop but not below
0.6 ppm, then:
When: What to do:
Every day Run pump and filter at least 6 hours every day.
Once a week Balance pH and total alkalinity.
Twice a week Check chlorine residual, add chlorine to maintain a minimum of 0.6 ppm free
available chlorine.
As needed • If water is hazy, superchlorination. Follow product label instructions.
• After heavy use or rainstorm, superchlorination is recommended.
• Add cyanuric acid (stabilizer) to maintain 50 ppm.

5 Provide Filtration/Circulation
To manage: You need to:
Circulation Follow the manufacturer’s directions for keeping the circulating pump in good working order and operate it at least six hours a day.
Consult your Nature2dealer for optimum run times.
Filtration Check the pool’s filter periodically and clean it as recommended by the manufacturer.
Algae may be caused
by insufficient levels
of oxidizer and/or
inadequate water
circulation.

Replacing the Nature2
Purifier Cartridge
Use the month indicator ring (M) on the top of the unit to identify the date on
which the cartridge should be replaced.
A cartridge lasts six months from the date of installation under normal operating
conditions.
To replace the cartridge:
1 Shut off your pool’s pump and filter.
2 Close any valves between the filter and pool to prevent draining the pool.
3 Unscrew the locking ring (A) by twisting counterclockwise until the ring is
free of the housing base.
4 Lift out the old cartridge and, if necessary, lubricate the O-ring (B).
Important: Use only a silicone-based, high viscosity grease. Do not use a
petroleum-based because it will damage it will damage the Nature2Purifier and
invalidate warranty.
5 Insert the new cartridge.
6Set the cap and locking ring in place and screw the ring clockwise until it
is snug. Do not overtighten.
7 Position the month indicator ring (M) on the cap so that the current
month is visible in the installation window.
8 Open any valves that were closed to isolate the Nature2Purifier.
9Restart your pool’s pump. Check for leaks and fix any leaking fittings.
10 Follow the start up procedures described on page 3.
5
Winterizing Your Pool
Use these steps as a guide. Consult your dealer for specific information on your area.
Warm Climate
1Reduce the number of hours the pump runs since the cooler weather
decreases the spread of algae and other pollutants.
2 There is no need to shock the pool during cool weather unless the water
becomes cloudy (as may occur after a winter storm). See Cloudy Water in
Troubleshooting section.
Cold Climate
1 Check total alkalinity and pH of pool to make sure that they are in
proper balance.
2 Vacuum the pool bottom to remove any debris or other potential contaminants.
3 Shock the pool to clear the water.
4 Add a winter algaecide following manufacturer’s instructions.
Important: Do not use a winter algaecide with copper in it. This will void the
Nature2no-stain warranty.
5 Backwash the filter.
6Drain part of the pool water. The amount to drain varies from one part of
the country to another. Consult your dealer for advice.
7Winterize the purifier as follows:
•Unscrew the locking ring (A) and remove cap from the purifier base.
•Remove the winter drain plug (E) and drain the water completely out of the base
of the purifier.
•Lift out the purifier cartridge and dispose of it.
• Set the cap O-ring (B), the cap and locking ring in place and screw it tight.
• Store the purifier with your pool equipment, indoors if possible.
8Winterize the pipes with pool antifreeze following manufacturer’s instructions.
9Drain the water out of all equipment (pump, filter, etc.).
10 Store all baskets, hoses and cleaning equipment, indoors if possible.
11 Cover the pool with a winter cover.
