Controller Installation and User’s Guide
IMPORTANT WARNING AND SAFETY INSTRUCTIONS
• Check the pH and sanitizer levels of the water before use.
• Periodically use an independent pH and Chlorine test kit to verify that pH
and chlorine is at a safe level. If the pH and Oxidation Reduction Potential
(ORP) or Flow Cell sensors are broken, depleted or dirty with oils, lotions,
or other contaminants, they can report inaccurate results to the system
causing incorrect water chemistry, which could harm people or equipment.
• Check the IntelliChem
®
Controller main status display each day to ensure
there are no Alarm messages. See “Troubleshooting” on page 45 for more
information.
Using CO2 for pH Control
Plaster pools and pools using salt-chlorine generators typically cause a slow pH rise which
must be managed. With the IntelliChem
®
controller muriatic acid or carbon dioxide (CO2)
is dispensed into the filter system’s return water as needed until the Flow Cell pH sensor
detects the proper pH level. Using CO2 for pH control eliminates the need to handle and
stored acid and can be a safer method. As CO2 gas is injected into the pool water, it
dissolves and creates carbonic acid. This weak acid is very efficient at lowering pH with
the added benefit of self-limiting if the CO2 is over-fed.
WARNING CHEMICAL BURN HAZARD: Make sure all pumps are
switched off at the main circuit breakers at the house before drilling into
any pipes. Securely fasten all electrical, water and chemical lines. Locate
chemical feed pumps and chemical storage tanks in a safe and secure
area.
Strictly follow the acid manufacturers safety and handling protocols
including hand, body and eye protection when transferring or handling
acid. Safety precautions should be used when handling Muriatic acid
to control pH water levels. Muriatic acid can cause serious body injury
and damage pool equipment. Extra care must be taken when installing,
maintaining and operating acid pump feed systems. Acid is dangerous to
handle and should be properly contained, transported, poured, stored,
and dispensed.
When using IntelliChem with a pool pump timer: The Association of Pool and Spa
Professionals (APSP) recommends that all water in a residential pool pass through
the filtration system at least once every 12 hours (referred to as pool water turnover).
However, many factors have an effect on actual pump and filter system run times. Pool
size, source of water, direct sun light, indoor/outdoor, screened and unscreened, filtration
system, cold or hot weather, swimmer load, rain, organic debris, algae, etc., are all factors
which contribute to either more or less pool pump and filter system run times. Because
of these differences, it is extremely difficult to set an initial run time (starting point) for the
pool pump and chlorinating system. Try initially setting the pool pump timer to 12 hours.
It will take a few days to get just the right amount pool pump operating time. When the
Chlorinator is wired with a pool pump timer (see page 6) results will vary greatly from one
pool installation to the next, so this should be discussed with either the pool builder or your
pool professional.
