ORP Set: Displays the current ORP set point value.
The adjustable range is from 650 to 800 in increments
of 10. The default ORP set point value is 700. The
ORP set point is the value that IntelliChem will try to
achieve based on the active sanitizer. To adjust the
ORP set point, press the button next to ORP Set.
STATUS: Displays the current communication link
between IntelliTouch and IntelliChem via the RS-
485 cable. IChem Comm Error: Check the RS-485
communication cable is connected to the COM port
on the IntelliTouch Personality circuit board.
USING SCG: “USING SCG” displays if the IntelliChlor
salt chlorine generator is enabled. The SCG is enabled and disabled from the MENU >
SETUP > EQUIPMENT > CHLORINATOR screen.
Note: IntelliChem must also be set up to use the
IntelliChlor SCG either with the AUTO SETUP
Setup Wizard (page 6) or the Configuration/

Hardness: Recommended range is 200-400 ppm.
Levels should be tested weekly. Cyanuric Acid:
Stabilizes chlorine in water from UV degradation.
When using the IntelliChlor SCG, cyanuric acid
level should be maintained between 30-50 ppm.
Total Alkalinity: APSP’s recommended ideal range for is 80 to 120 ppm for “gunite” and
concrete pools and 125-170 ppm for painted, vinyl, and fiberglass pools. Test levels weekly
and adjust according to your pool professional’s recommendations.
Saturation Index: The saturation Index displays IDEAL (Optimum levels), CORROSIVE
or SCALING. The following are recommended pool chemistry Saturation Index levels: pH
range: 7.2 to 7.6 ORP range: 650 to 800. Alkanlinity: 80 to 120 ppm. Calcium
Hardness: 200 - 500 ppm. Cyanuric Acid/Stabilizer: 30-50 ppm.
