Hayward AquaRite® 120 Operation Manual - Page 6

Salt Level Use the chart on page 4 to determine how much salt in pounds or (Kgs) need to be added to reach the recommended levels. Use the equations below (measurements are in feet/ gallons and meters/liters) if pool size is unknown. Gallons (pool size in feet) Rectangular Length x Width x Average Depth x 7.5 Round Diameter x Diameter x Average Depth x 5.9 Oval Length x Width x Average Depth x 6.7 Liters (pool size in meters) Length x Width x Average Depth x 1000 Diameter x Diameter x Average Depth x 785 Length x Width x Average Depth x 893 The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. If the level is low, determine the number of gallons in the pool and add salt according to the chart on page 4. A low salt level will reduce the efficiency of the Aqua Rite® and result in low chlorine production. A high salt level can cause the Aqua Rite® to shutdown and may begin to give a salty taste to your pool (generally, the salt will begin to be tasted at a level of about 3500-4000 ppm). The salt in your pool/spa is constantly recycled and the loss of salt throughout the swimming season should be small. This loss is due primarily to the addition of water because of splashing, backwashing, or draining (because of rain). Salt is not lost due to evaporation. Type of Salt to Use It is important to use only sodium chloride (NaCl) salt that is greater than 99% pure. This is common food quality or water softener salt and is usually available in 40-80 lb. bags labeled "Coarse Solar Salt". It is also acceptable to use water conditioning salt pellets, however, it will take longer for them to dissolve. Do not use rock salt, salt with yellow prussiate of soda, salt with anti-caking additives, or iodized salt. How to Add or Remove Salt For new plaster pools, wait 10-14 days before adding salt to allow the plaster to cure. Turn the circulating pump on and add salt directly into the pool. Brush the salt around to speed up the dissolving process--do not allow salt to pile up on the bottom of the pool. Run the filter pump for 24 hours with the suction coming from the main drain (use pool vac if there is no main drain) to allow the salt to evenly disperse throughout the pool. The salt display may take 24 hours to respond to the change in salt concentration. The only way to lower the salt concentration is to partially drain the pool and refill with fresh water. Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together. Use the chart on page 5 to determine how much stabilizer must be added to raise the level to 80 ppm. 3 Wiring Power must be shut off at the circuit breaker before performing any wiring. Be sure to follow Local and NEC electrical codes. To provide safe operation, the Aqua Rite® must be properly grounded and bonded. Input Power For stand alone operation: Wire the Aqua Rite to the LOAD SIDE of the filter pump timer. It is very important that the Aqua Rite is powered only when the pump is running. Refer to the wiring label on the Aqua Rite as well as the diagram below to determine correct wiring connections. The Aqua Rite is shipped from the factory with the configuration jumpers in 240VAC position. If using 120VAC, move the jumpers as shown below. For Canadian models, the Aqua Rite shall be connected to a circuit protected by a class A ground fault interrupter. Be sure to connect the ground wire to the green ground screw terminal located on the bottom of the enclosure.

Bonding: A lug used for bonding is attached to the bottom of the Aqua Rite enclosure (see diagram below). The Aqua Rite must be bonded with an 8 AWG copper wire (6 AWG Canada) to the pool bonding system. Electrolytic Cell and Flow Switch: The electrolytic cell and flow switch cables are terminated with connectors which plug into the Aqua Rite, for easy attachment and removal. The door of the Aqua Rite must be open to access the cell cable connector. The flow switch plugs into a connector (similar to a telephone jack) located outside, on the bottom of the enclosure. Refer to the diagram below for the location of these connections. Flow switch connector Cutout for cell cable Bonding lug to pool bonding system 12
