IMPORTANT WARNING AND SAFETY INSTRUCTIONS

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.

• 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 main status display each day to ensure there are
no Alarm messages. See “Troubleshooting” on page 46 for more
information.

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.

Using CO2 for pH Control

Plaster pools and pools using salt-chlorine generators typically cause a slow pH rise
which must be managed. With IntelliChem, 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.

IntelliChem™ Installation and User’s Guide

Overview

IntelliChem is a pH and ORP sensing device that dispenses correct amount of chlorine
or bromine, muriatic acid or CO2 gas. IntelliChem 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. IntelliChem operates with or without a salt chlorine
generator to provide a self-replenishing supply of chlorine generated from salt.
IntelliChem 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. IntelliChem
supports Pentair Water Pool and Spa® (“Pentair”), EasyTouch®, IntelliTouch® and
SunTouch® automation control systems for pH and ORP control. IntelliChem also
supports IntelliChlor® salt chlorine generator (SCG) to help manage your pool water
sanitizer levels.

Operating IntelliChem

Before operating IntelliChem, 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 Installation and User’s Guide (P/N 520589). During normal
IntelliChem operation, no user input is required, IntelliChem 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 IntelliChem “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.

First Balance Your Pool Water

IMPORTANT: To help keep your pool water balanced follow these steps:

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 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 built-in LSI calculator
(see page 24-27). Refer to:
http://www.pentairpool.com/pool-owner/resources/calculators/langelier/

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 +0.3
to -0.3 is considered satisfactory in a swimming pool. See Saturation Index menu on

page 24.

pH Dosage (for Internal and External Pumps)

pH Dosage (page 1/2)

Mixing Time: Select the amount of time in hours and minutes that IntelliChem 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 (by Volume/Time): Choose the feed method: “by Volume” 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”.

pH Dosage (page 2/2)

Dose (Volume): Displays the current dose size (0-9999) in ounces [oz] or milliliters [ml].

Set the amount of ounces (or milliliters) that IntelliChem will feed pH (acid) each time
IntelliChem calls for pH chemicals. The Dose (Volume) is set by Auto Setup wizard based
on pool volume and filter run time.

Dose (Time/Setpoint): Displays the current pH dose (feed) time. Sets the amount of time
in hours, minutes and seconds that IntelliChem will feed pH (acid) each time IntelliChem
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 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. IntelliChem 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.

To protect the pool water, IntelliChem will automatically shutdown pH and ORP feed
control and display an alarm message if IntelliChem (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 Set Point

Displays the current pH set point value. Adjust the pH set point to meet pool and spa
chemistry standards. The adjustable range is from 7.2 to 7.6 in increments of 0.1. The
default pH set point value is 7.5.

pH Sensitivity

IntelliChem 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 IntelliChem
to reach the exact set point.
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
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 will dispense only 1 ounce at a time.
This can be confusing to someone who is watching the IntelliChem because it will
appear to not be dosing the full amount; therefore, in the Advanced display mode, the
process timer will be shown as "%Dosing 0.1 oz", the "%" indicating that the dosage is
reduced due to this Sensitivity feature.

pH Alarms

IntelliChem 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.
IntelliChem 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 IntelliChem displays
the alarm message on the main screen. The Delay setting is adjusted in increments of 15
seconds.
