Chemical Cleaning
Sensor Storage
Chlorine sensors can be refreshed with p/n A1100227,
Chlorine sensor renew solution.
Short Term: Immerse the sensor tip in tap water.
This procedure should be done over a sink. Wear
plastic or rubber gloves as the solution is acidic.
Wash hands thoroughly with lots of water if the
solution comes in contact with the skin.
1. Remove the protective cap exposing the coils
and gold tip.
2.
Immerse in cleaning solution as shown (Figure
19) for 5 to 10 minutes, or until deposits
Wet storage is good for a week or two.
CAUTION: If a wet sensor dries out in storage
there may be none repairable damage.
LongTerm: Dis-assemble the Chlorine sensor tip and pour
out the fill solution. Rinse the coils, gold tip, and membrane
module with demin water and blot dry with a paper towel.
Re-assemble the Chlorine sensor dry, and store dry with the
tip covered.
Dry storage can be used for a year or more.

disappear.
3.
Remove and rinse in Distilled or Demin water,
use wiping in the direction of the coils or a
toothbrush to speed removal.
4.
Repeat 2 & 3 until coils and tip look clean and
have a shine, then re-assemble Chlorine
sensor with new membrane and fill solution,
calibrate and check efficiency is above 50 %.
5.
Repeat 2 to 4 as necessary to get at least 50
percent efficiency. If not possible, Chlorine
sensor should be replaced.
