Troubleshooting; Common Problems And Solutions - Hayward AQR100 Manuel Du Propriétaire

Visit www.hayward.com or call (908)-355-7995 for helpful information on operation, maintenance
and troubleshooting your AQR100 Electronic Chlorine Generator.

Common Problems and Solutions

The AQR100's various LEDs show the operation status as well as alert the user to any problems
that may have occurred. Some indications may require a combination of LEDs to illuminate. To aid
in interpreting these indications, Hayward has created an interactive tool located at www.hayward.
com. Use this tool and the information below to identify and correct problems that may arise.
1. Possible causes of little or no free chlorine residual
•
DAILY CHLORINE OUTPUT adjustment setting is too low
•
Low stabilizer (Cyanuric Acid)
•
Filter pump time too short (8 hours for average size pools, more for large pools)
•
Salt level too high
•
Very warm pools increase chlorine demand--increase Output %, or filter run time
•
Cold water below 50ºF causes AQR100 to stop generating
•
Cold water between 50ºF - 60ºF causes AQR100 to reduce output regardless of DAILY
CHLORINE OUTPUT setting
•
Excessive scaling on Cell.
•
High level of Nitrogen in pool water.
•
"Yellow Out" or similar treatment recently used. Some yellow algae treatments will use
chlorine at a very high rate and deplete the residual free chlorine. Manually shock the
pool if indicated in the directions on the algae treatment. It still may be a matter of days
before the pool returns to "normal" and chlorine tests will show the desired 1-3 ppm free
chlorine reading.
2. LEDs not on
Depending on current conditions, there should always be at least one LED illuminated when
the AQR100 is powered. If no LEDs are on, check to make the unit is receiving power. If no
power is detected, the circuit breaker may have to be reset.
3. STANDING BY LED blinking
The AQR100 has shut down because the temperature of the pool/spa water is too high
(120ºF) or too low (50ºF). The system will not resume operation until the water temperature
returns to normal. NOTE: This condition can sometimes happen if the pool/spa temperature is
already high and the heater is running. The temperature coming out of the heater and into the
Cell could possibly be high enough to shut down the AQR100.
4. INADEQUATE WATER FLOW LED illuminated
The AQR100 has sensed a low flow or no flow condition and has stopped generating chlorine.
•
Verify that the filter pump is running and there are no obstructions or restrictions in the
pool plumbing.
•
Backwash the pool filter.
•
Increase the speed of your variable speed pump
