Congratulations, you are now the owner of a O'Clair pH First, which allows
you to regulate the pH of your pool simply and easily.
The pH First measures the pH value between 0.0 (acidic) and 14.0 (alka-
line) using a pH sensor on the filtration system, which constantly analyzes
the water in your pool.
Depending on the value measured, the pH First dosing pump injects the
amount of product needed to maintain the balance of the water in the pool.
The pH First will function with either acid or alkaline dosing.
