With all the variables mentioned above, it may take you
a couple weeks to fi nd the right production rate for your
pool.
To adjust the output level, follow these steps:
1. Turn the power pack on by pressing the
button.
2. Press the buttons to reach the desired output
level. The minimum setting is 10%. The output can
be adjusted in increments of 10% up to 100%. This
controls the amount of run time for the cell.

5.5 BOOST/LOW Mode

The BOOST mode can be used to maximize chlorine
output for a short period of time. To activate BOOST
mode, press the and
boost will turn off after 24 hours. To turn off BOOST
mode manually, press the
The LOW mode can be used to minimize chlorine output
while activated. To activate LOW mode, press the
and buttons simultaneously. The LOW mode will
stay on indefi nitely. To turn off LOW mode, press the
button

5.6 Polarity Reversal

The Jandy Pro Series chlorine generating device is a
reversible polarity cell which means that the cell will
periodically switch its polarity to help prevent any build
up of calcium on the cell plates. This is sometimes
referred to as the automated cell cleaning feature. During
the transition between changing its polarity there is a
brief period when the cell will not produce any chlorine.
Once it has changed polarity, it will continue to make
chlorine.
'CLEANING' will be displayed on the screen during
NOTE
the 'WAIT' period. The output level indicator will remain
as set during the cleaning period.
Section 6. Maintenance
Instructions
Before servicing the Jandy Pro Series chlorine
generating device please ensure you have read and
understood the Important Safety Instructions section.
Always test the chlorine levels of your pool
IMPORTANT
before each use. During heavy usage where bather load
is increased, chlorine levels may deplete quickly and
require more adjustments. Monitor the chlorine closely,
and take appropriate measures in order to maintain the
recommended 1 - 3 ppm free chlorine residual.

6.1 Weekly

1. Chlorine Test. Test pool water chlorine level
with a reliable test kit. Maintain an ideal range
by adjusting the chlorine output level on the
power pack (see Section 5.4) or if necessary, by
Jandy Pro Series TruClear
®
buttons simultaneously. The
button.
Chlorine Generating System
™
supplementing the chlorinator with additional dry
or liquid chlorine. The recommended free chlorine
level is 1 - 3 ppm. See section 4.5 for instructions
on collecting a water sample.
Never use glass containers in the pool area. Broken
NOTE
glass becomes diffi cult to see under water.
2. pH Level Test. Test the pH level of your pool with
a test kit. If necessary, adjust to maintain a pH level
of 7.4 - 7.6 (see Section 4.3).
Never use dry acid to adjust pH in arid geographic
areas with excessive evaporation and minimal
dilution of pool water with fresh water. A build up of
by products can damage the electrolytic cell.
3. Total Alkalinity Test. Test pool water for total
alkalinity with a test kit. Take steps necessary to
maintain an alkalinity of 80 - 120 ppm (see Section
4.3).
4. Calcium Hardness. Test pool water for calcium
hardness level using test kit or by having a water
sample tested by a pool professional. Adjust as
necessary to maintain a calcium hardness of 175 -
400 ppm (see Section 4.3).

6.2 Monthly

1. Check the cell. It is recommended that the cell
be inspected every month for scale and/or calcium
deposits. Light colored, crusty deposits known
as scale will form in excessively hard water or
from pool water that is out of balance. Following
the installation of the Jandy Pro Series chlorine
generating device, check the cell once a month
for signs of scale. Hold the plate bundle to a light
source so the light can be seen between the plates.
If the light is easily seen through the plates and/or
a small amount of scale is visible, the cell does not
need to be cleaned. Reinstall.
On the other hand, if the light is barely visible
through the plates or the light is totally blocked by
scale, then the cell needs to be cleaned. See Section
6.3 for instructions.
Excessive cleaning can shorten the life of your cell.
NOTE
2. Salt Level Test. Use salinity test strips, a TDS/
salinity meter, or another reliable method to test the
salinity of the pool water. Once the existing salinity
has been established, use Table 1 to determine the
amount of salt to add to reach the desired level.
Be conservative when adding salt as it is easier to
add more if needed than it is to dilute if there is too
much salt. If the salinity level of the pool is correct
and the salt LED does not go out, see Section 7.
