Bromine Generator. Cal Spas Portable Spa

Bromine Generator

The bromine generator automatically generates and releases free bromine into the spa water. You will still need to test for bromine and occasionally adjust it to return the bromine level to the baseline.

Start-up/Operating Instructions

Be certain that you start with a clean spa. It should be free of contaminants and other residues that can accumulate on the sides and/or around the jets. It is also important to only use spa cleaning products that have

no phosphates

or phosphonic acids since phosphates will deplete free bromine and are super-food for algae. Always start your spa with a clean filter before filling with water.

If the water source is “well water” or a non-municipal water source, have your water tested for Total Dissolved

Solids (TDS) and metals. Water with high TDS is likely to have higher metal content and will need a metal remover to decrease the metals and ensure a successful start. This test can be done by your local spa dealer.

The ideal range for your start-up TDS is between 50 and

200 ppm - mg/L. If TDS from your source water is above

500 ppm, a metal remover is strongly recommended.

DO NOT FILL THE SPA WITH SOFT WATER.

3. Determine the level of “NaBr” (Sodium Bromide) required for your spa size. NaBr should be added at a rate of 1.2 lbs per 100 gallons or approximately

1300-1500 ppm.

Example:

For a 500 gallon spa add approximately 6 lbs of NaBr.

gallons = 6lbs NaBr.

1.2 lbs x (5) 500

1. Using your PURE FILL Spa Pre-Filter, fill your spa with water to the recommended level (six inches below the lip of the spa) and DO NOT FILL WITH WATER FROM A

“RESIDENTIAL WATER SOFTENER.”

4. Turn the jets on high speed. Sprinkle the NaBr across the surface of the water to evenly distribute the NaBr in the spa and circulate for 30 minutes.

2. Before starting the system, balance your water chemistry to ensure a successful start up. Ideal ranges are as follows:

5. Test the Sodium Bromide concentration with the

Tru-Blu NaBr test kit. The correct amount of NaBr will secure a reading of between 1300-1500 ppm.

Ideal Range

6. Adjust the filtration time to circulate for 8 hours every

24 hours on a 2 speed pump.

Use the phosphate test kit included with your system.

Bromide residuals will be significantly reduced if phosphate levels are high. If phosphates are detected, purchase a phosphate remover and follow the directions accordingly.

Any

phosphates in your spa will reduce bromine levels.

7. For a spa between 300-500 gallons, start at a power level of “6” and then press the “boost” feature. This will accelerate the production of bromine for 8 hours. Wait for proper bromine levels before entering the spa.

8. Always keep your bromine level between 3-5ppm. Test the bromine level after 24 hours and adjust the power setting accordingly. An occasional heavier bather load may require the “boost” feature.
