Lo Flow - OFF scrolls across the display
Possible cause:
Flow sensor lead is not connected or poor contact is made.
Solution:
Connect sensor lead to terminal marked ‘sensor’ on cell.
Possible cause:
Flow sensor is detecting insufficient or no water flow through cell.
Solutions:
• Check that pump is operating and actually pumping water.
• Are skimmer and pump baskets clean?
• Are valves in the correct positions?
• Is the filter restricting the flow? If so, backwash filter.
• Is the pool level high enough?
• Is the pump sucking air?
• Is the skimmer door obstructing the water flow?
• Is the inlet to the cell blocked with debris? If so, clean and
investigate filter problem. Water is bypassing filtration medium.
• Is the pump losing prime?
• Has the solar system just powered up? On start up, the dis
placed air in the system may switch cell off briefly.
• Were you in the process of backwashing or vacuuming to
waste?
Chlorine output display reads a lower value than that which was set
Possible cause:
Salt level is too low for the unit to operate at full power but not low
enough for a warning message to scroll across the display.
Solution:
Add more salt.
Possible cause:
Fluctuations in main voltage.
Solution:
No action required, since effect on output is negligible.
No chlorine residual in swimming pool
Possible cause:
Chlorinator is not operating sufficient hours per day.
Solution:
Check time clock ON/OFF periods and adjust accordingly.
Possible cause:
Cell electrode is coated with a mineral or metal coating.
Solution:
Clean electrode as described in this manual.
Possible cause:
Percent Chlorine output setting is too low.
Solution:
Increase percent Chlorine output setting.
Possible cause:
Cyanuric acid (Stabilizer) level in pool is insufficient.
Solution:
Increase levels as specified.
Possible cause:
Heavy usage of pool.
Solution:
Use the BOOST function regularly or shock pool using an
approved oxidizing agent as per the manufacturers instructions.

CHLORINE PRODUCTION AND CONTROL
A free chlorine residual of 1.5ppm to 3.0ppm should be maintained. This level will
alter with respect to bather load, debris falling into the pool and the pools water
temperature. These factors alter the demand for chlorine as will the water
balance and filtration’s effectiveness. (Refer to equipment manufactures
specifications with regard to maximum chlorine level permissible.)
The percent of chlorine output is displayed on the control box and may be altered
using the UP/DOWN buttons. This allows you to increase or decrease the chlo-
rine production without altering the operation time.
Testing for chlorine levels is very important and should be performed regularly
by pool owners and periodically cross referenced by using the services of a pool
water professional. See your local pool shop or service person.
The sample of water to be tested should be taken at arms depth away from the
pool returns. This avoids highly chlorinated water, which has travelled directly
from the chlorinator cell and ensures the reading will be a true representation of
the pools residual level.
Testing for chlorine production rather than the pools chlorine residual, is
performed by taking a sample directly at the pool return. This water is directly
from the cell and should indicate a higher chlorine level than that obtained in the
pool residual test. (Note: This test must be done while the unit is set to 100%)
The chlorine output may be altered In three ways:
1. Increasing or decreasing the operating time. Depending on the pool and
model chosen, the daily operating time may be from 4 to 12 hours per day.
(There are exceptions to this, some pools run 24 hours)
2. Increasing or decreasing the output percentage. This allows for a finer
control over the chlorine level.
3. Linking the unit to a Redox (ORP) probe device. The probe senses the
chlorine level in the pool and will switch the chlorinator on and off to maintain
the recommended level.
(Highly recommended for use in indoor pools and
spa’s) Call your AquaPower Dealer to purchase
Note: It may be necessary to periodically shock the pool water in high
demand situations. Consult with your pool professional regarding how to
shock.
