Congratulations you’re now a Saltron Retro owner. There are a few things you should know before starting your Retro. Understanding these will assist in the startup on your Retro and implementing the optimal operation.
First, start with, how big is your spa? Knowing how many gallons of water your pool holds is vital as this will assist in the determination of the amount of salt that is needed to run the Retro at a proper level between 3000 to 4000ppm.
Once you know the size of your pool, you can calculate the amount of salt needed by using a tool at https://poolchemicalcalculator.com/. You will enter the size of your pool at the top of the tool where it asks for “Pool Gallons”; enter your “Current Salt” level in the field marked as indicated and enter 3000 in the “Desired Salt” field and press Calculate. It will then provide you with the correct amount of salt needed for your pool. For example: If you have a 15,000-gallon pool and your “Desired Salt” is 3000ppm of salt, and you have not added any salt yet, then you will need to add 377 lbs of salt. That will be 9.4 of 40 lb bags of salt.
Once you’ve added the salt, you will need to wait 24 hours for it to dissolve before using the Retro in the pool.
Next, you will want to confirm that your pool water is balanced before starting your Retro. You should have 2 – 4ppm of free chlorine. We suggest shocking the pool water before beginning the Retro system. Why? Shocking the pool will provide you with the residual of chlorine that you need as well as clean the water of any pre-existing contaminants that may already be residing in the water. Also, it can takes days for the Retro to get the free chlorine up to 2 to 4ppm from 0ppm of free chlorine.
Make sure all pool chemistry is optimal before beginning the Retro:
Free chlorine 2 -4 ppm
Salt Level 3000 - 4000ppm
pH 7.2 – 7.6ppm
Total Alkalinity 80 – 120ppm
Cyanuric Acid 60 – 80ppm
Total Dissolved Solids 0 - 1500ppm (after subtracting the salt level)
Calcium Hardness 250 - 350ppm
The Retro will start its run cycle based on the time you plug it in and then for the number of hours you program in the power supply (preset for 24 hours). For example, you plug it in at 9am and schedule 8 hours. It will run every day at 9am until 5pm; unless you unplug it or adjust the hours.
The number of hours you will need to run your Saltron Retro can be determined after running the system for three days. After running the system, check the chlorine level because it varies by individual usage and pool size for the demand of chlorine. So for the first few weeks, you will need to test your water and adjust the time as necessary to ensure a proper run time.
