OPERATING INSTRUCTIONS BACKGROUND Auto-Chlor is a chlorine generator for pool and/or spa sanitation. It is the workhorse of chlorine generators.
The system uses a very low concentration of salt, less than the concentration in a human teardrop, and
converts it into free chlorine that kills algae and bacteria in your pool. After killing the algae and bacteria, the
chlorine reverts back into sodium chloride. This process of purification continues, making the need to add
extra sanitizing chemicals to your pool virtually unnecessary.
The level of necessary chlorine in the pool is affected by a number of factors such as sunlight, bather load,
debris and water temperature, all of which increase sanitation and filtration demand.
Filtration
Proper filtration is critical for maintaining clean healthy water. Filtration increases clarity, and the Auto-Chlor
Chlorine Generator increases sanitation and oxidation. It is customarily required in the pool industry that all
the water in the pool pass through the filter at least one and a half (1 ½) times per day (~ 8 hours on most
pools). During very heavy usage, the filter and chlorine generator may be run continuously.
Inadequate filtration: Inadequate filtration reduces water clarity and makes more work for the generator.
Sanitation/Oxidation
The Auto-Chlor Chlorine Generator has little effect on pH, total alkalinity, or stabilizer levels. These must still
be monitored and adjusted to allow the system to have its greatest effect. If you use a good quality pool test
kit and follow the simple instructions outlined in this manual, your Auto-Chlor Chlorine Generator will help you
maintain a sparkling clean, trouble-free pool for many years with minimal effort. See the section titled
“Understanding the Chemistry” for more information.
The Auto-Chlor Chlorine Generator produces a pure form of chlorine to sanitize and oxidize your pool water.
The chlorine residual needs to be maintained at 1-3 ppm. This may be tested using a standard kit or by your
local pool store.
To generate more chlorine:
1. Turn the Control Knob to a higher setting as necessary, 10% to 100% chlorine production level. See
“Power Meter” in the next section for more details.
2. Ensure sufficient run time (at least 8 hours / 1 ½ turnovers) up to 24 hours per day.
3. Ensure salt level is correct and the Cell is clean (see “Salinity Indicator” in the next section).
4. Ensure proper water balance including pH and stabilizer levels (see “Understanding the Chemistry”
for recommended levels).
5. Point pool jets down and to the side.
* Summer weather increases demands for chlorine.
To decrease chlorine production:
1. Turn the Control Knob to a lower setting, 10% to 100% chlorine production level. (See “Power Meter”
in the next section)
2. Decrease run time as necessary.
Winterizing
Just like the pool plumbing, freezing may damage the system’s Cell and Flow Sensor. If severe or extended
periods of freezing temperatures are possible, drain all water from the pump, filter, and supply and return lines
before any freezing conditions occur.
Spring Start-up
DO NOT turn on the system until the pool water chemistry has been brought to required levels. See “Startup”
section for more information.
