Preparing the Pool Water
It is important that the pool's water chemistry is balanced before the SJ-Series is powered on and used. In
order for the system to be able to work, there must be a minimum level of salt in the pool water, see “Salt
Levels” below. In order to achieve normal pool operation, water chemistry needs to be balanced according to
the national standards listed under "Ideal Chemistry Levels" on page 8.
DO NOT add chemicals or salt directly to the skimmer. This may damage the Cell. If the system has already
been installed, it should not be turned on before adding salt. Additionally, leave the salt chlorinator off any
time there is a chance of recently added chemicals going through the salt Cell in a concentrated form.
For New Pools / Remodels: wait 30 days or longer if specified by your builder for plaster to cure before adding
salt.
For Biguanide (Non-Chlorine) Pools: ensure any Biguanide-based chemicals have been removed prior to startup.
Ideal Salt Levels & Pool Size
The CircuPool SJ-Series can work within a broad salinity range, from a minimum of 3500 ppm (parts per
million), to upwards of 5000 ppm. However, the ideal level for operation is around 4000-4500 ppm. To achieve
this level of salinity, use the chart on page 7, which will help you add approximately 35 lbs of salt for every
1000 gallons of water (or 4 Kilograms of salt for every 1000 Liters). If you are unsure of the number of gallons
in your pool, double-check with the following equations.
