2. Installation
2.1 Preparing the pool: water balance
The TRi is designed to disinfect the water in the pool by means of its salt chlorination function.
With the TRi pH module, it automatically maintains the pH value of your pool.
With the TRi PRO module, it automatically maintains the pH value and chlorine level (ACL or Redox potential) of your pool.
It is essential for the water balance of the pool to be checked and adjusted before installing this equipment. Ensuring the
water balance of the pool is correct from the start will reduce the likelihood of encountering problems in the first days
operation or during the season using the pool.
Even if it is an automatic control system, it is essential to analyze the water regularly to check the water balance
parameters.
