Manual
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 every
month the cell be removed and inspected for
scale formation and/or debris. If cell needs to be
cleaned, see Section 6.3 for instructions.
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 in the
pool is correct and the salt LED does not go out,
see Section 7: Troubleshooting.
3. Pool Water Sample. Take water sample to local
pool store for testing.
4. Stabilizer (Cyanuric Acid). Test pool water
stabilizer (cyanuric acid) level using a test kit
or by having a water sample tested by a pool
professional. Maintain ideal range of 10 - 50 ppm.
Follow your pool professional's recommendations.
For indoor pools, it is not necessary to add
chlorine stabilizer to the swimming pool water.
5. Metals Test. It is recommended that the pool
water be tested periodically for the presence of
metals such as iron, and manganese. These
metals should not be present in the pool water. If
those metals are present, contact your local pool
professional.

CAUTION
6.3 Cleaning the Cell
WARNING
Disconnect power to the system at the main circuit
breaker before performing this procedure to avoid risk
of electric shock which can result in property damage,
severe injury or death.
WARNING
•
When cleaning the cell, wear protective
eyeglasses and gloves.
•
When mixing acid with water, ALWAYS ADD ACID
TO WATER. NEVER ADD WATER TO ACID.
The power pack has an automatic cell cleaning feature
(polarity reversing) that removes scale deposits from the
cell (see Section 5.5).
Scale will form in excessively hard water or from pool
water that is out of balance and in a scaling condition.
Following the installation of the chlorine generating
device, check the cell once a month for signs of scale.
If the cell has a tendency to scale, it is recommended
that every month the cell be removed and inspected for
scale formation and/or debris. Some filters allow debris
to pass through to the cell which could lodge between
the plates in the cell. A small amount of scale formation
is normal. If by looking through the cell it is observed that
there is excessive scale formation between the plates or
debris is present, the cell must be cleaned as follows:
1. Ensure that all power to the power pack and the
controller is disconnected/turned off at the circuit
breaker.
2. Before removing the cell for cleaning, shut off any
necessary valves to prevent any water loss.
3. Open the air relief valve to release any pressure in
the pool system.
4. Remove the terminal cap and cell leads.
5. Undo the locking ring. If required, use the locking
ring tool provided (see Figure 31).
6. Remove the cell (see Figure 32).
7. Refit the cap on the cell and invert (see Figure 33)
With protective glasses and gloves on, add one (1)
part muriatic acid to ten (10) parts water and mix.
8. Fill the cell to the top of the electrode plates with
the acid solution. A foaming action will begin,
which is caused by scale (calcium carbonate)
being dissolved from the plates. If rigorous
foaming action does not begin, the cell does
not need to be cleaned (STOP THE CLEANING
PROCESS - go to the step 10). Otherwise allow
the cell to remain in the solution until the foaming
has stopped (approximately 5 - 10 minutes).
