TerraSpa Installation Instructions:
Thank you for purchasing the TerraSpa shower de-chlorinator system, one of the many fine environmental products from Global Environmental Technologies. Our hope is to provide you with a high quality product, while keeping a commitment to the environment we live in. We hope you enjoy using your TerraSpa and welcome any comments or suggestions to better our products.
Your TerraSpa Shower De-chlorinator
The TerraSpa Shower De-chlorinator removes most of the chlorine present and also saves water and energy!
It makes sense to remove the chlorine from our showers as well as from our drinking water because many authorities feel that we absorb more chlorine from one shower than from drinking the same water in one day.
Chlorine and You
Chlorine is universally used to chemically purify water. Municipal water suppliers use chlorine and its derivatives to effectively destroy microorganisms in drinking water.
Chlorine is also familiar as a bleaching agent. Almost every home uses household bleach in its laundry. To be an effective bleach, it is necessary that a substance must also be able to attack organic matter. Chlorine does this very well. Our skin, hair, lungs, and eyes are also organic - and chlorine attacks these as well. Chlorine bonds with the protein in our bodies making hair dry and unmanageable, and sensitive dry skin flake and itch.
More About Chlorine
Chlorine exists in two forms - combined available chlorine and free available chlorine. Combined available chlorine is present as chloramine or other derivatives in water. Free available chlorine is the residual chlorine present as a dissolved gas, hypochlorous acid, or hypochlorite that is not combined with ammonia. It is free available chlorine that presents the most danger to humans, and it is this form of chlorine that the TerraSpa removes. NOTE: Simple OTO type chlorine tests cannot be relied upon to show the presence of free available chlorine. This type of test also shows the presence of combined chlorine. When testing for free available chlorine, an inexpensive test is the GPO type test method.
Installation
1. If desired, the month reminder dial (1) may be flipped over for easier viewing. Unscrew the two halves (2 & 3) of the shower filter and reposition the month dial in the preferred direction.
2. Remove the existing showerhead from the shower arm, but do not loosen the shower arm. If needed or desired, various adapters are available at your local home improvement store.
3. Being careful not to cross-thread the pipe connection, install the TerraSpa onto the shower arm. A few wraps of Teflon tape is recommended.
4. Re-install the showerhead onto the TerraSpa shower filter. A few wraps of Teflon tape is recommended.
5. Line up the month reminder dial with the “INSTALLED” (4) arrow as a reminder of when it was installed. This arrow is molded into the plastic near the showerhead.
6. Turn on the shower to check for leaks and let the water rinse through the filter for about one minute. You are now ready to enjoy your shower filter.
How Long Will Your TerraSpa Shower De-chlorinator Last?
In most conditions, the TerraSpa shower filter will reduce free chlorine for about one year, or 10,000 gallons, which ever occurs first. Replacement cartridges are available from Global Environmental Technologies. You may place an order online or by phone at 800.800.8377
Care of your TerraSpa Shower De-chlorinator and "Back flushing"
The ability of the TerraSpa to continue to remove chlorine will depend on the quality of the water source, the amount of chlorine and hardness, and how much the TerraSpa is used. Over a period of time, reduction of water flow may be experienced. Should this occur, the TerraSpa may be "back flushed" as follows:
1. Remove the TerraSpa from the shower arm.
Remove the showerhead from the TerraSpa.
Turn the TerraSpa around and attach the back flushing coupling (supplied) to the outlet of TerraSpa (see Fig. D).
Attach the coupling to the shower arm.
Turn on the shower and flush the TerraSpa with warm water for several minutes at full flow.
2. Remove the unit and reassemble using Teflon joint sealing tape.
The TerraSpa uses a patented filter medium to effectively remove chlorine. This filter medium is many times more effective than the carbon used in most water filters. Unlike carbon, the filter medium is more efficient in hot water. It also reduces fungus, algae, and hydrogen sulfide. Its bacteriostatic characteristics inhibit the growth of new bacteria in the TerraSpa filter.
The length of time that the TerraSpa will reduce the chlorine level in your shower water will depend on the level of chlorine present, pH, amount of water used, the hardness of the water and the care of the unit. If the unit is back flushed as required it should last a year or more under average water conditions.
Using a Flow Restricting Water Head
The TerraSpa must be attached to a showerhead that regulates the water flow rate to 2.5 gallons per minute (GPM) from water pressure as low as 15 pounds per square inch (psi) to pressures as high as (100 psi). This requirement not only results in substantial energy and water savings, but it is also crucial for the effective operation of the TerraSpa filter. Restricting the flow of water through the TerraSpa insures the proper "contact time" of the water within the filter.
DO NOT USE SHOWERHEADS WITH FLOW RATES GREATER THAN 2.5 GPM AT 60 PSI. TO DO SO WILL REDUCE YOUR TerraSpa FILTER'S ABILITY TO REMOVE CHLORINE FROM THE SHOWER WATER.
NOTICE OF LIMITATIONS
• The TerraSpa is designed for potable water systems only. Do not allow your TerraSpa to freeze, or use with water over 110 F. (43 C.) temperature. Maximum water pressure should not exceed 100 psi. Do not use in systems with high iron content using chemicals such as polyphosphates.
• The TerraSpa is not to be used for drinking purposes.
