Safety Instructions
Important Information
Please read prior to installation
Nature2® Express Cartridges have been designed to sanitize swimming pools from 5,000 to 25,000 gallons.
ATTENTION
EQUIPMENT UNDER PRESSURE
- Always turn pump off prior to installing or changing Nature2 cartridge. Your pump/filter system is operated under pressure and the pressure must be released before you begin work. Please see your pump/filter owner’s manual for further instructions.
PREVENT CHILD DROWNING
- Do not let anyone, especially small children, sit, step, lean or climb on any equipment installed as part of your pool’s operational system. Locate the components of your operational system at least 3 feet from the pool so children cannot use the equipment to access the pool and be injured or drown.
LOW CHLORINE RECIPE
- You must strictly follow the low chlorine recipe included in this manual to maintain proper water chemistry and avoid health hazards. Failure to follow these instructions can lead to sickness from bacteria and other noxious organisms.
CAUTION
PRECAUTIONARY STATEMENT
HAZARDS TO HUMANS AND DOMESTIC ANIMALS
CAUTION
In the unlikely event that a cartridge breaks, mineral media should not be
ingested by humans or animals as it may cause gastric distress.
FIRST AID
IF INGESTED : Call poison control center or doctor immediately for treatment advice.
The Nature2 Pool Sanitizer is designed only for residential swimming pools.
- The Nature2 System consists of the Nature2 technology† used in conjunction with a chlorine delivery device or 0.5 ppm of an EPA registered chlorine pool product.
† Nature2 technology consists of the minerals silver and copper.
We ask you to take the time to get familiar with this manual.
Thank you for purchasing Nature2. We believe the more you know, the more enjoyable 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 conventional chemical programs to the Nature2 System* spend less time maintaining their pools. Every pool has its own characteristics of water type, amount of sunlight, etc. The recipe included in this manual will help insure good water quality for your pool. Remember, your Nature2 dealer can provide advice and service.
DIRECTIONS FOR USE:
It is a violation of Federal law to use this product in a manner inconsistent with its labeling.
NATURE2 COMPATIBILITY
Nature2 Systems can be used with all types of pool chemical treatments
available except biguanide products and copper based algaecides.
Important: When converting a biguanide treated pool to the Nature2
System, the pool must be completely drained and refilled. Then follow the
Nature2 cartridge start-up procedure below.
Start Up
-
Before starting up a new Nature2 cartridge, clean debris and algae out of the pool and pool equipment.
Important : Do not install the new cartridge until the pool water is clean and chemically balanced. -
Balance pool water before installing Nature2 cartridge.
- pH 7.4-7.8
- Calcium hardness 200-400 ppm
- Total alkalinity 80-150 ppm
Consult with your Nature2 Dealer for specific water balance instructions.
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 Range: 7.4-7.8
| If it’s too low:| The surface of your pool can become etched.
Metal parts in the pump and plumbing will corrode.Add pH increaser.
---|---|---
How to fix:
If it’s too high:| “Scale” forms on the surface of your pool.
The water can become cloudy.
Equipment can become damaged.Add pH decreaser.
How to fix:
Element: CalciumHardness Range: 200-400ppm
| If it’s too low:| Water is less stable.
In plaster pools, the calcium is taken out of the plaster, causing the surface
to deteriorate.Add calcium hardness increaser
How to fix:
If it’s too high: How to fix:| Rough, discolored deposits
(“scale”) will form on the pool surface and inside pool equipment.
Drain or dilute the pool water.
Consult your dealer.
Element: Total Alkalinity Range: 80-150 ppm
| If it’s too low:| It provides no buffer so that you constantlyget fluctuating pH readings, which can damage equipmen and pool surfaces.
Use an alkalinity increaser.
How to fix:
If it’s too high:| White deposits (“scale”) form on the tile line.
The plaster on pool surface becomes rough or discolored.The water becomes
cloudy or milky white.
Add acid to bring alkalinity down.
How to fix:
Install the Cartridge
-
Install the cartridge after water is balanced. Refer to your Nature2 Express operating manual for additional instructions.
-
Superoxidize the pool water with chlorine according to manufacturer’s instructions to burn off contaminants and activate cartridge.
Important: Initial superoxidation with chlorine is required to burn off contaminants and activate cartridge. -
Run the circulating pump either:
• 24 hours a day for 4 days, maintaining 1-2 ppm free chlorine throughout, or
• 6 hours a day for 14 days, maintaining 1-2 ppm free chlorine throughout. -
Let chlorine dissipate to 0.5 ppm once start up period is completed.
• Do not enter the pool if the free available chlorine residual is over 3 ppm.
Recipe
There is one (1) recipe for maintaining clean, clear, sanitized water with
minimum time and effort.
This recipe provides the easiest and most economical way to care for your
Nature2 pool.
Low-Chlorine Recipe
Ingredients:
- Nature2 Cartridge
- Chlorine granules, tablets, liquid or generator
- pH and total alkalinity adjusting chemicals
- Calcium hardness increaser, if needed
- Water test kit
Once the 4-day or 14-day start-up period is done, allow the free available chlorine residual to drop to 0.5 ppm (by reducing the amount of chlorine you add) then:
| When: | What to do: |
|---|---|
| Every day | Run pump and filter at least six (6) hours every day. |
| Once a week | Balance pH and total alkalinity. |
| Twice a week | Check chlorine residual; add chlorine to maintain at least a 0.5 |
ppm range using the chart below.
As needed| If water is hazy, superoxidize with chlorine according to
manufacturer’s instructions. Additional shocking is recommended following
rainstorms or heavy bather load. Do not re-enter the pool if the free
available chlorine residual is over 3 ppm.
Add the following amounts of chlorine per 10,000 gallons of water to increase free chlorine by 0.5 ppm.
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 (6) hours a day.
Consult your Nature2 dealer for optimum run times.
Filtration| Check the pool’s filter periodically and clean it as recommended by the manufacturer.
Nature2 Cartridge Replacement Intervals
Use the month indicator ring on the top of the cartridge to identify the date on which the cartridge should be replaced. Always turn pump off prior to installing or changing Nature2 Express cartridge. Your pump/filter is operated under pressure and the pressure must be released before you begin work. Please see your pump/ filter owner’s manual for further instructions.
A cartridge lasts six (6) months or one (1) season, whichever is shorter. The cartridge should not be used longer than six (6) continuous months.
Winterizing Your Pool
Use these steps as a guide. Consult your dealer for specific information in your area.
Warm Climate
- Reduce the number of hours the pump runs since the cooler weather decreases the spread of algae and other pollutants.
- There is no need to superoxidize 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
-
Check total alkalinity and pH of pool to make sure that they are in proper balance.
-
Vacuum the pool bottom to remove any debris or other potential contaminants.
-
Superoxidize the pool with chlorine according to manufacturer’s instructions to clear the water.
-
Add a winter algaecide following manufacturer’s instructions.
Important : Do not use a winter algaecide with copper in it. This will void the Nature2 no-stain warranty. -
Backwash the filter.
-
Drain part of the pool water. The amount to drain varies from one part of the country to another. Consult your dealer for advice.
-
Remove the Nature2 cartridge and discard with household trash.
-
Winterize the pipes with pool antifreeze following manufacturer’s instructions.
-
Drain the water out of all equipment (pump, filter, etc.).
-
Store all baskets, hoses and cleaning equipment, indoors if possible.
-
Cover the pool with a winter cover.
Disposal
After six (6) months of use, discard Nature2 cartridge in household trash. Do
not save the cartridge for re-use.
The cartridge is manufactured with the mineral media sealed inside. In the
unlikely event a cartridge breaks, remove it and vacuum out any media
introduced into the pool.
Troubleshooting Guide
| Problem| What to look for
---|---|---
Cloudy water
Frequently caused by improper start up. See section on Start Up and Install
the Cartridge.| Poor filtration| Slow filter turnover rates.
Algae growth| Hazy pool water; may have slightly green appearance.
Unbalanced water| 1. High hardness 2. High TDS (total dissolved solids) 3.
High pH 4. High total alkalinity
Algae
Algae may be caused by insufficient levels of oxidizer and/or inadequate water circulation.
| Green algae| Pea green color; attaches to pool walls; and sometimes colors
the entire body of water.
Black algae| Black spots on pool walls.
Mustard algae| Yellow or brown film on steps or walls.
Note: Regular algaecide treatments are recommended for outdoor pools that
experience persistent algae problems. Do not use algae treatments containing
copper.
Stains| Blue/green| Copper or iron from pool equipment corrosion or
water supply.
Red/brown| Iron or manganese from equipment corrosion or water supply.
Black| Manganese in water supply.
Metal tarnishing| High native mineral content in water; unbalanced water.
Scale| Crusty deposits on pool surfaces| High pH and high total
alkalinity.
High TDS (total dissolved solids) or high hardness levels.
