Hayward Aqua Trol Above Ground Salt System!Model W3AQ-TROL-RJ-TLThis model is for Return Jet installations with a Twist Lock Cord 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 free electronic chlorination is the ideal alternative to traditional factory produced chlorine for soft, silky-smooth water. Plumbing InstructionsThe 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. Return Jet installation (-RJ option): Unscrew the the hose adaptor from the pool return jet fitting and, in its place, screw in the right-angle cell mounting adaptor. Note that this installation does NOT require a flow switch--however it is very important that the cell be mounted vertically directly below the return jet in order to allow the gases produced in the cell to naturally dissipate in the pool. Attach the cell to the union and then use the fittings supplied to attach the lower end of the cell to either the hose or rigid PVC pipe coming from the pools filtration system. Tighten all union nuts BY HAND for a watertight seal. Wiring Instructions Power must be shut off at the circuit breaker before performing and wiring. Be sure to follow Local and NEC/CEC electroical codes. The Aqua Trol has been designed to easily wire into typical above ground pool systems. To provide safe operation, the Aqua Trol must be properly grounded and bonded. Models with the standard 120 VAC line cord should be plugged into a GFCI receptacle. Twist lock models should be plugged into a twist lock receptacle wired to a GFCI circuit breaker. For Canadian installations: Connect to a circuit protected by a Class-A ground fault interruptor.
