2 Eko 3 Systems, Inc. carbon dioxide feed systems are unique in that CO 2 consumption is reduced by as much as 50% over conventional CO 2 feed systems. A booster pump is employed to drive a mass transfer system followed by a contact chamber all of which assure total absorption and utilization of CO 2. Natural bicarbonate buffers are generated during the mass transfer process and contact time provision. These buffers generated by the Eko 3 ph-mts provides for ph stability. Easy to install, automatic in it s operation. Powered by 110 volts and controlled by 24 VAC. The Eko 3 ph-mts feed system is easy to install. All materials necessary for installation and hook-up are included. The ph-mts can be manually controlled, but, ideally will be connected to an automatic swimming pool water chemical controller, where ph level is continually monitored and controlled at optimum level. The Eko 3 ph-mts feed system is connected to the pressure regulator of a single or dual CO 2 gas cylinder, or a more economical low pressure bulk liquid CO 2 storage system. Carbon Dioxide is the Natural and Safest ph control substance. Carbon Dioxide (CO 2 ) is the only chemical of choice for safe ph control. Carbon dioxide is an odorless, colorless, and tasteless gas, which makes up a percent of the air we breathe. Carbon dioxide molecules contain one atom of carbon and two of oxygen. The chemical formula for carbon dioxide is CO 2. Municipal water treatment plants use carbon dioxide for lowering ph. Innovations within the swimming pool industry in years past have proven that CO 2 does effectively replace Muriatic or dry acid for lowering the ph of swimming pool water, as well. Swimming Pool water treated with CO 2 is much safer for bathers, and will extend the life of equipment, and swimming pool structures. Mild carbonic acid forms when CO 2 is dissolved into water. Being a milder acid than Muriatic it is nearly impossible for even a runaway CO 2 feeder to lower pool water to dangerously low ph levels CO 2 generates a natural bicarbonate buffer that makes the water more stable and prevents the ph from fluctuating widely. With total alkalinity at the proper level, ph changes are very gradual, making ph is easier to maintain at recommended levels. Using CO 2 to adjust swimming pool ph eliminates storing and handling dangerous acids. CO 2 does not create corrosive fumes, so it has no damaging effect on equipment or electrical panels. Unlike strong acids, if CO 2 and liquid or dry chlorine were accidentally mixed, no chlorine gas would be release. This removes the possibility of chlorine gas formation in the re-circulation system or pool area. 1

3 What is ph? ph is a number used to indicate the strength of an acid or base. The number is usually on a scale ranging from 0 to 14. A ph below 7 indicates that a solution is acidic, and a ph above 7 indicates that a solution is basic. Strong acids have lower ph s then weak acids, and strong bases have higher ph s than weak bases. A neutral solution, such as pure water, is neither acidic nor basic. Its ph is 7. Without any outside influence, the ph of an isolated body of water will remain stable and not change. However, swimming pool water is exposed to several things that can push ph in one direction or the other. Some of the influencing factors include rain, make-up water, soils, sweat, urine, and chemicals such as chlorine and algaecides. The ph numerical value represents the logarithm of the reciprocal of the hydrogen icon concentration of swimming pool water. When calculating swimming pool water balance, ph has a dominant influence. Higher ph values move the balance towards the scale forming side, while lower values move the balance towards the corrosive side.

4 ph-mts Operations & Maintenance Manual, rev. #10/10/00 Operating instruction for the Eko 3 Systems Carbon Dioxide (CO 2 ) Feed Device 1. WARNING!: The cryogenic, carbon dioxide, storage tank must not be allowed to run completely out of gas. The tank must be refilled when it is 75% empty. Failure to fill the tank at this time will result in failure of the tank-heating element. 2. The regulated pressure of the CO 2 gas feed at the cryogenic storage tank must be set between twenty (20) and thirty (30) pounds per square inch (p.s.i.), maximum. 3. CO 2 gas will periodically vent from the cryogenic storage tank to atmosphere. Do not be alarmed if and when this episode takes place. On extremely hot days the cryogenic tank-heating element may be unplugged to minimize venting. 4. Operation of the ph-mts CO 2 Feed System is automatically controlled by the Strantrol System 4 water chemistry controller. With a rise in the ph of the water being treated the Strantrol System 4 will call for the reduction of ph by turning on the ph-mts booster pump and opening the electric solenoid valve within the control box of the ph-mts system. CO 2, a mild acid, will be fed through the mass transfer system (injector) into the systems contact tank with the result being a reduction in the ph of the swimming pool water. 5. The feed rate of CO 2 at the ph-mts feed system is to be set between 60 and 160 SCFH (Standard Cubic Feet Per Hour). A SCFH flow meter is provided and mounted on the control box of the ph- MTS feed system. The higher the feed rate the better. The compound, pressure/vacuum gauge supplied with the system, must indicate zero (0) pressure or preferably a vacuum of 1 or greater. Set the feed rate of carbon dioxide at the maximum sustainable, while maintaining the zero to slight vacuum reading at the compound gauge. All feed rate settings must be made while the system is in operation. 3
