Pool Water Chemistry, Conditions And Precautions - Pentair INTELLICHLOR IC15 Installation And User Manual

This section describes the start-up procedure and operating instructions for IntelliChlor
Generator (SCG).

Pool Water Chemistry, Conditions and Precautions

1. New Pool Water: A recently filled or newly-refinished pool may contain undesirable matter. This
undesirable matter could interfere with SCG's ability to chlorinate properly. Make sure the water is
tested by a pool professional and properly balanced before switching on the SCG.
WARNING - Salt is an inherently corrosive material. While the levels of salt required for proper operation of
the IntelliChlor Salt Chlorine Generator are relatively low when compared to sea water and other salt solutions,
placing any amount of salt in your pool increases the likelihood of corrosion or other deterioration of pool
equipment and any surfaces used in and around your pool. Metal parts (including steel pools) and certain
natural and man-made surfaces are particularly susceptible to corrosion and deterioration when used in and
around salt water pools. Pentair Water Pool and Spa ("Pentair") does not represent or otherwise guarantee that
the proper use of the IntelliChlor Salt Chlorine Generator will prevent corrosion or other deterioration of pool
equipment and any surfaces used in and around your pool. Consult your experienced pool professional, who
should be able to advise you on the proper material selection, installation techniques for those materials, and
the proper use, care and maintenance of those materials for your specific pool type and location in order to
minimize the corrosion and deterioration that is inherent in and around salt water pools.
2. Super Chlorination burns out the swimmer waste that has combined with chlorine. This frees the
chlorine for sanitizing. This is accomplished by raising the chlorine level quickly and dramatically.
When the chlorine level is raised to ten (10) times the amount of combined chlorine (usually 5 to 10
ppm) the pool water is said to have been super chlorinated. As pool water is continuously passed
through the SCG while the unit is powered on, all pool water inside the SCG is being super
chlorinated. When the IntelliChlor Salt Chlorine Generator is used on pools, the pool water sparkles
is less likely to contain chloramines.
Note: On initial start-up of a pool, it is best to super chlorinate using an outside source, i.e.,
use a shock treatment available at your local pool supplier.
3. Chloramines should not be present in pool water. Chloramines are formed when ammonia (which is
found in urine and sweat) combine with free chlorine. This ties up the free chlorine in your pool and
does not allow the chlorine in your pool to disinfect. Chloramines also burn the eyes and are foul
smelling. Super Chlorinate to remove chloramines at the initial start-up of the pool and as needed to
maintain proper levels of free chlorine.
4. Cyanuric acid is needed in outdoor pools to help to stabilize and maintain proper levels of chlorine.
90% of unstabilized chlorine is destroyed by the UV radiation from the sun within two hours.
Cyanuric acid stabilizes chlorine in water from UV degradation. When using the SCG, the cyanuric
acid level should be maintained between 30-50 ppm. See Table 2, on page 14. NOTE: DO NOT USE
CYANURIC ACID IN INDOOR POOLS.
5. Total Dissolved Solids (TDS): Adding salt to pool water will raise the TDS level. While this does
not adversely affect the pool water chemistry or clarity, the pool water professional testing for TDS
must be made aware salt has been added to the IntelliChlor system. The individual performing the
TDS test (see page 20) may then subtract the salinity level to arrive at a TDS level that would be
compatible to a TDS reading for a non-salt water pool.
