Hayward Aqua Trol Above Ground Salt System! Model W3AQ-TROL-HP This model is for Hose / Pipe installations The Aqua Trol Electronic Chlorine Generator (also known as a salt chlorinator) is designed specifically for above ground pools up to 18,000 gallons. The Aqua Trol has all the same functions and features of the Aqua Rite but with a lower chlorine output. The Aqua Trol also has an integral time clock for control of the pool filtration pump. Since many above ground pools already have a single electrical outlet for the filter pump, the Aqua Trol is designed with an outlet (timer controlled) for the filter pump to plug into, the Aqua Trol then plugs into the original outlet the filter pump was using. The savings on chlorine and electrical power alone (if the pump was previously running 24 hours), will have the Aqua Trol paying for itself in just a few short years. The Aqua Trol system typically installs in less than 30 minutes and is very easy to operate. What a Little Salt Can Do No more mixing, measuring and messing around with liquid or tablet chlorine again. Now you can automatically turn ordinary salt into a self-regenerating supply of pure chlorine for both pool and spa water that's clean, clear and luxuriously soft. Electronic chlorination has become the simple, safe and affordable alternative to using harsh, chemically-produced chlorine to sanitize pools and spas. Unlike traditional chlorine treatments that require a regular routine of monitoring and replacing chlorine, electronic chlorination produces chlorine from common table salt. The key is our patented Turbo Cell, a specially designed converter connected to the control unit. As water passes through the Turbo Cell, an extremely safe electrical charge turns the salt previously added to the water into fresh sanitizing chlorine which is then dispensed evenly throughout the pool. Just a teaspoon of salt per gallon is all it takes. Installation is quick, easy and suitable for any new or existing pool. No chlorine odor, low operating costs, pays for itself, and is virtually maintenance freeelectronic chlorination is the ideal alternative to traditional factory produced chlorine for soft, silky-smooth water. Plumbing Instructions The cell and flow switch are plumbed in the return line to the pool. Install after (downstream) all the pool equipment (filter, heater, solar,etc.). The kit included in the Aqua Trol provides the necessary plumbing components for either 2" (51mm) rigid PVC piping installation or 1 - 1" (38-32mm) flexible hose installation. Hose/Pipe installations (-HP option): Install the cell and flow switch as shown in the diagrams below. Always make sure that the flow switch is downstream from the cell. When using the hose adaptors, remove the o-ring from the pipe union tailpiece and install them in the hose tailpieces. Tighten all union nuts BY HAND for a watertight seal.
