Troubleshooting - Acuva Eco Owner's Manual

2. Replace the inline 5-micron carbon filter after winterization or after 2000 gallons,
whichever comes first.
3. It is not necessary to regularly de-scale Acuva UV-LED water purifiers, as the small
quartz windows inside the UV device do not heat up or cause minerals to stick as
experienced with UV lamps. It is although good practice to visually inspect the inside of
the purifier annually to confirm that the quartz windows have no mineral build-up. If
scaling is observed, a quick rinse with CLR or food grade descaling solution is
recommended to remove the mineral buildup.
3.2 Winterising
:
exposed to freezing temperatures can lead to damage and water leakage.
To prevent freezing, pump a non-toxic antifreeze into the water system or flush with
compressed air. Open the point of use faucet connected to the Acuva device and pump non-
toxic antifreeze or air until you see the antifreeze or air coming out of the faucet. In the spring,
remember to flush with fresh water to clear the antifreeze before use.

water
Flashing Red light +

sound
Solid Red light +
continuous alarm
sound
No Blue light while
the faucet is open
Warning: Failure to properly winterize the device before it is
Cause
•
At low flow rates (1 lpm),
dissolved air may be released
into bubbles to give a greyish
color to the water.
•
The system is over-heated
due to the high
ambient/water temperature
or excessive operation.
•
UV LED malfunction
detected.
•
No DC power
•
The minimum pressure/flow
rate required for activating
the UV system (mentioned in
section 2.2.) is not provided.
•
This is absolutely no issue with the water
quality. The bubbles will burst quickly and
water becomes clear after about 1-2
minutes.
•
Turn-off the faucet and allow time for the
system to cool. Alarm sound will stop. The
flashing red light will continue until the
system cools down.
•
Do not use the system.
•
Turn-off the faucet. Alarm sound will stop.
The steady red light will stay on.
•
Disconnect the power and reconnect to try
and clear the fault. Make sure the power
plug is properly attached to the system.
•
If the red light persists, unplug the system
and contact customer service.
•
Check DC power.
•
Use a more powerful pump.
•
Check if the connection polarity is correct.
