The chlorine level is 2.
too low but the pool
water looks fine.
TYPICAL SOLUTION
The chlorine setting has been fine, but a temporary
boost of chlorine is needed to adjust for rain or a
temporary bather increase. Press the BOOST button
to temporarily elevate the chlorine production level to
100% for 24 hrs. The chlorine output will revert to the
original setting after 24 hrs.
The chlorine setting has been fine, but a temporary
(or longer) Super Boost of chlorine is needed to
adjust for heavier rain or bather increase. Press and
hold the BOOST button for 8 seconds to temporarily
elevate the chlorine production level to 100% for
72 hrs. The chlorine output will revert to the original
setting after 72 hrs.
Check pool chemistry parameters. (See "Water
Balance and Chemistry Recommendations" on page
7 in the "Owner's Quick Start" section of manual.) The
Cyanuric acid level may be low and the chlorine is
being consumed quickly by the UV from the sun.
The chlorine output needs to be increased.

Use the UP arrow key to increase the chlorine
output setting.

Increase the pump run time so the Digital
Nano/Nano+ is generating chlorine for a longer
period of time.
Consult your local pool service professional and test
for high phosphate levels. Use a product such as Lo-
® ®
Chlor Lo-Phos to reduce phosphates.
If the water temperature is 55°F (10°C) or colder, the
®
Pool Pilot has automatically turned the Chlorine
output down to 1% to avoid over-chlorination.
Bacteria and algae activity is greatly reduced at these
temperatures, so, this should not be a problem. Hand
dose additional chlorine if necessary.
Obtain an independent salt reading to check the Pool
®
Pilot reading. Add salt, if needed, and re-calibrate
®
the Pool Pilot salt display.
Check the "Max temp" in the Setup Menu. If higher
than the Shutoff temp., unit may be going into a
cooling mode. Shade, or relocate unit to an area less
affected by direct sunlight or other sources of heat
external to the unit.
Possible Digital Nano/Nano+ fault.

Press BOOST. Wait 10 seconds for the unit to
start the Boost cycle.

Press MENU. Select "Test Pool Pilot"; record
the Volts and Amps when displayed. If the Volts
are less than 4.0 and the Amps are less than 1.5,
contact the factory for assistance.
The test kit reagents or strips may be old or have
been exposed to sunlight. Replace the kit or reagents
and retest.
There is too much chlorine in the pool. The chlorine is
bleaching the test kit reagents.

Dilute the water sample with distilled water and
retest. Lower the chlorine output setting with the
DOWN arrow button if the chlorine level is too
high.
