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 Balance Your Pool Water
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.
