in accordance with the National Electrical Code (NEC), NFPA 70 or the Canadian Electrical Code
(CEC), CSA C22.2. All applicable local installation codes and ordinances must also be adhered to.
Improper installation will create an electrical hazard which could result in death or serious injury
to pool users, installers or others due to electrical shock, and may also cause damage to property.
Do not permit children to operate this equipment.
When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD
WATER TO ACID. When adding any chemical to the pool/spa, be sure to follow
the manufacturer’s instructions thoroughly.
DO NOT MIX SODIUM HYPOCHLORITE AND MURATIC ACID
Risk of electrical shock. Connect IntelliChem controller to a ground-fault
interrupter-circuit (GFCI). Contact a qualified electrician if you cannot verify that
the receptacle is protected by a GFCI.
BE SURE TO DISCONNECT ALL SUPPLY CONNECTIONS BEFORE
SERVICING THE INTELLICHEM CONTROLLER. AC Power may be supplied
to the relay terminals Ex_Relay1 and Ex_Relay2 from other sources. See
page 31 for details.
BEFORE USING YOUR POOL, SPA OR HOT TUB, CHECK THE
pH AND SANITIZER LEVELS OF THE WATER.
IF “CLEAR OVERFEED LIMIT” SETTING IS SET TO 24 HOURS, DO NOT
SET “FEED TIME” GREATER THAN 20 HOURS AS THIS WILL VOID NSF
CERTIFICATION.
DO NOT INSTALL THE INTELLICHEM® CHEMICAL CONTROLLER WHERE IT CAN BE ACCESSIBLE TO THE
PUBLIC.

INTELLICHEM®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.

Overview
The INTELLILCHEM®Water Chemistry Controller is a pH and ORP sensing device
that dispenses correct amount of chlorine or bromine, muriatic acid or CO2 gas.The
IntelliChem controller provides continual analysis of your swimming pool water sanitation
and pH levels, providing real-time status information to dispense the proper amount of
muriatic acid (pH reducer) and chlorine or bromine for the correct sanitization and pH
balance.The IntelliChem controller operates with or without a salt chlorine generator
to provide a self-replenishing supply of chlorine generated from salt.The IntelliChem
controller can also connect to carbon dioxide (CO2) liquid gas tanks to lower pH in
your swimming pool water.When CO2 dissolves into water it produces weak neutral
bicarbonate salts which reduces pH. CO2 is environmentally friendly and produces no
secondary pollution into the treated water by salts such as chlorides or sulfates. CO2 does
not corrode metal equipment and does not require any special piping.The IntelliChem
controller supports Pentair Aquatic Systems (“Pentair”), EasyTouch®, IntelliTouch®and
SunTouch®automation control systems for pH and ORP control.The IntelliChem controller
also supports IntelliChlor®salt chlorine generator (SCG) to help manage your pool water
sanitizer levels.
Before operating the IntelliChem controller, it’s important to test and adjust your pool
water chemistry to the recommended pool industry levels found in this manual (see
page 19). If you are using an IntelliChlor salt chlorine generator, adjust the salt levels
to the recommended levels in the IntelliChlor (SCG) Installation and User’s Guide (P/N
520589). During normal operation, no user input is required, the IntelliChem controller
will automatically sense ORP and pH levels.The current ORP and pH levels are regularly
displayed on the control panel LCD display. Use the pH Settings or ORP Settings buttons
to view or adjust supply levels.The “Auto Setup” feature provides screen prompts for
first-time setup or standard configurations such as setup reminder times, calculating feed
times, proportional limits and alarms. For details, see page 6.
Operating the IntelliChem Controller
First BalanceYour PoolWater
1. Use a Test Kit (with fresh testing reagents) to measure the pH, alkalinity,
and calcium hardness of the pool water. For greater accuracy, Pentair
recommends the AcuCheck3 Test Kit to measure pH, chlorine ppm, and
alkalinity levels (P/N 745000110). “Balanced” water has proper levels of
pH, Total Alkalinity and Calcium Hardness.This “balanced” water is neither
corrosive or scaling.The pH (0-14) value is the scale of relative acidity
or alkalinity. Recommended pH range is from 7.2 to 7.6.The IntelliChem
controller default pH value is 7.5 (see page 12).
2. Be sure the pool chlorine level is balanced. Ideal free chlorine level should
be between 1.0 - 3.0 parts per million (ppm).
3. Use the online Langelier Saturation Index (LSI) calculator to diagnose
the water balance in your pool or the IntelliChem controller built-in LSI
calculator (see page 28-31). Refer to:
http://www.pentairpool.com/pool-owner/resources/calculators/langelier/
IMPORTANT: To help keep your pool water balanced follow these steps:
Note: A Saturation Index value of 0 indicates the water is chemically in balance. If the
Index is a minus (-) value, corrosive tendencies are indicated. If the Index is a plus (+)
value, scale-forming tendencies are indicated. A Saturation Index value between +0.5
to -0.5 is considered satisfactory in a swimming pool.See Saturation Index menu
on page 28.

pH Dosage (page 1/2)
MixingTime: Select the amount of time in hours and minutes that the IntelliChem®
Controller will wait in between pH feeding. It should be set to allow sufficient mixing time
for the chemicals to become distributed throughout the pool.The pH Mixing Time is set by
Auto Setup.
Dose (byVolume/Time): Choose the feed method:“byVolume” and “by Time” are
available choices for liquid dosers, as determined by the hardware setup. If CO2 is
selected, then the available choices are “by Time” and “To Setpoint”.If pool volume is less
than 4k gallons, these units automatically get set to milliliters (ml) for better resolution.

Dose (Volume): Displays the current dose size (0-9999) in ounces [oz] or milliliters [ml].
Set the amount of ounces (or milliliters) that the IntelliChem controller will feed pH (acid)
each time the IntelliChem controller calls for pH chemicals.The Dose (Volume) is set by

Dose (Time/Setpoint): Displays the current pH dose (feed) time. If pool volume is less
than 4k gallons, these units automatically get set to milliliters (ml) for better resolution.
Sets the amount of time in hours, minutes and seconds that the IntelliChem controller will
feed pH (acid) each time the IntelliChem controller calls for pH chemicals.The pH dose
time is set by Auto Setup.The Dose (Time) is set by Auto Setup wizard based on pool
volume and filter run time. Dose (to Setpoint) does not have a dose amount, only a time
limit.
Limit (Time/Volume): Displays the current feed limit. Sets the maximum amount of
time/volume in hours, minutes and seconds or volumetric units that will be allowed to
feed pH chemicals. As a safety feature, the IntelliChem controller will only allow a certain
amount of pH chemicals to feed into the system in a 24 hour period. Set the maximum
amount of time in hours (0-24) that will be allowed to feed.The IntelliChem controller
tracks each dose time, and adds them together. When the maximum dose time is reached
or exceeded, the ORP feed system is prevented from feeding until the next 24 hour period
begins, or when the feed timers are cleared manually.The default pH Limit is based on a
safe limit of 2 ppm of the size of the pool, up to a 5 oz maximum.The Limit (Time/Volume)
is set by Auto Setup wizard based on pool volume and filter run time.

water, IntelliChem controller will automatically shutdown pH and ORP feed control and
display an alarm message if IntelliChem controller (or any other dispensing device) runs
non-stop for more than the selected Limit time or volume. This prevents IntelliChem from
non-stop feeding pH reducer, because of a sensor error or external problem with the pool.
This allows you to evaluate the pool chemistry before continuing with pH feeding.

pH Sensitivity
The IntelliChem®Controller can adjust the feed times for pH depending on how close the
current reading is to the set point.This helps to prevent overshooting and makes it easier
for the IntelliChem controller to reach the exact set point.Note: Low = (default) Full dose
at 0.5 pH above setpoint. High = Full dose at 0.2 pH above setpoint.
Off = Full dose at 0.005 pH above setpoint
To set the pH Sensitivity level: Press MENU - pH Menu /pH Sensitivity 
pH Alarms
The IntelliChem controller automatically displays a screen message indicating the pH level
has reached or exceeded the HIGH (7.8) or LOW (6.8) pH alarm level settings.The
IntelliChem controller will automatically set a high and low alarm for the pH level.The
Delay time is the amount of time between the detected alarm condition and when the
IntelliChem controller displays the alarm message on the main screen.The Delay setting
is adjusted in increments of 15 seconds.
Press MENU pH Menu pH Alarms /pH Alarms /

Press to select the alarm, High level and Delay Time (00:50:00).
To set the pH alarm “High” level and “Delay” time (page 1/2):
Press MENU /pH Menu pH Alarms /Low / Delay (2/2)
Press /to change pH alarms Low level and Delay Time (00:05:00).
To set the pH alarm “Low” level and “Delay” time (page 2/2):
For example:When set to LOW (full dose at 0.5 above setpoint), if pH setpoint is 7.2 and
pH reading is 7.7 or above, a full dose amount is dispensed. As the pH comes closer to
setpoint, say 7.45 (0.25 above setpoint - or- half the 0.5 pH value), the dispensed amount
will be 1/2 of the specified dosage.And, at 0.05 (1/10th of 0.5 value) above setpoint (7.25),
the dosage will be 10% of that specified in the dosage menu.In that case, if the dosage
was specified to be 10 ounces, IntelliChem controller will dispense only 1 ounce at a time.
This can be confusing because the display appears to not be dosing the full amount;
therefore, in the Advanced display mode, the process timer shows “%Dosing 0.1 oz”, the
“%”indicates the dosage is reduced due to this Sensitivity feature. In SPA Mode,
the leading“s”in “sDosing 0.1 oz” indicates the dose is further reduced by 25%.

Spa Mode is activated when the IntelliChem Controller detects that the control system has
turned on the Spa.The SPA indicator should be illuminated on the automation control panel.
Switching from a large body of water like a pool to a typically a smaller spa automatically
reduces the dispensed dosage to 25% of a normal dose.The IntelliChem’s Advanced
display precedes the Dosing message with a “s” to indicate it is in this mode.This feature is
only available if the IntelliChem Contrroller is connected to a Pentair control system.
