3.
Make sure the power switch (Figure 4, #2) is off and the
ORP selection knob (Figure 4, #9) is rotated counterclock-
wise to the lowest setting.
4.
Turn on the filter pump and then the controller power switch.
The red power light (Figure 4, #1) and indicator lights on the
controller light bar array (Figure 4, #8) will come on.
5.
Leave the system running for approximately five minutes so
the sensors can get an accurate reading from the pool.
6.
Check for leaks and correct as necessary.
G. Sanitizer Settings
Be careful when adjusting the ORP set knob. The dial is
extremely sensitive in the 600 to 800 mV range and an adjust-
ment of 50 mV could change the sanitizer level by several parts
per million.
1.
The average pool should have a sanitizer level between
1.0 and 3.0 ppm. This equates to approximately 650 mV on
the controller’s ORP light bar array. If the pool has been
balanced correctly, the lights illuminated on the ORP light
bar array should be near 650 mV. Adjust the ORP selection
knob to point at the illuminated light on the ORP light bar
array. If more than one light is illuminated, set the knob to
point in between the two lights.
To maintain a higher sanitizer level, set the selection knob
above the light shown on the light bar array. To maintain a
lower sanitizer level, set the selection knob below the light
shown on the light bar array.
2.
Allow the system to operate for 24 hours.
3.
With the filtration system running, retest the sanitizer level
using a test kit and adjust the sanitizer selection knob if
necessary. It may require two to three days to accurately set
the controller to maintain the ideal sanitizer level.
4.
If the chemistry of the pool or spa water changes (e.g. refill-
ing, significant changes in pH, build-up of total dissolved
solids, additions of other chemicals, etc.), the sanitizer
selection knob may have to be adjusted.
