Water Chemistry - Pool Pro CPP Series Installation & Operating Instructions Manual

7. WATER CHEMISTRY

The Pool Pro unit is designed for use with swimming pool water balanced in accordance with
the Langlier Saturation Index with a pH range of 6.8-7.8.
As previously advised, for best performance and operation of your Pool Pro unit, certain water
balances must be maintained within your swimming pool. Have your water tested regularly.
Transport the test water in an opaque container and have the test done as soon as possible for
the most accurate results. Following is a list of recommended water chemistry levels.
7.1 Chlorine
Ideal Chlorine (Free Chlorine) Levels: 2 - 3ppm (2 - 3mg/L) and no more than 4ppm (4mg/L).
Adjust the chlorine output by turning the Output Control Knob clockwise to increase and anti-
clockwise to decrease (NEVER run unit with the Meter needle in the RED). Running the unit for
longer or shorter hours can achieve the same result.
7.2 Salt
Ideal Salt Levels: 3000-3500ppm and no more than 4000ppm.
Although salt is not consumed by the chlorinator, salt is lost during backwashing, pool
overflow, splashing and on bathers that use it. The correct salt level allows for the most
efficient production levels and electricity consumption.
The salt level SHOULD NOT go below 3000ppm. Operating the unit with too little salt in the pool
will cause damage to your Cell.
Salt is the essential element by which your unit operates. Not enough salt means not
enough chlorine - this simple rule governs the total operation of your Pool Pro unit, and
insufficient salt will damage your Cell. Use Pool Pro Ultrafine Salt or Pool Pro Premium Salt to
keep optimum salt levels.
The unit will operate with good stability on higher salt levels but it is still advisable to run
at the correct level to prevent damage should the Output Control Knob be turned up by
accident. Salt levels above 4000ppm may overload the unit and cause excessive heat.
