GF 263X Series Chlorine Electrodes
Sensor Preparation
•
Chlorine sensors are shipped without internal electrolyte solution.
•
Prior to installation and supplying power, Chlorine sensors must be
fi
lled with the appropriate internal electrolyte solution.
•
Verify the correct electrolyte solution is utilized with the corresponding sensor.
•
Free Chlorine and Chlorine Dioxide sensors require different electrolyte solutions.
Avoid skin or eye contact with electrolyte solution.
Wear rubber gloves and goggles.
*Safety Data Sheets (SDS) are available online at www.gfsignet.com.
CAUTION!
DO NOT touch the gold tip or the membrane of the sensor.
Initial Fill Procedure:
When adding electrolyte, be prepared for an accidental spill.
Working near a sink is recommended.
1.
Remove the protective bottle from the end of the electrode.
2.
Remove the membrane cap from the front of the sensor.
Note:
When new sensors are shipped, the membrane cap is not tightened to
the sensor.
3
. Fill supplied syringe with electrolyte solution.
4.
Place the electrode on a level surface.
5.
Insert syringe needle fully into one of the eight electrode holes while injecting
with electrolyte solution. Slowly injecting the electrolyte solution into the sensor
to avoid introducing air bubbles. The electrode holds approximately 14
milliliters of solution. Slowly
fi
ll until solution begins to
fl
ow out of holes. Do not
allow the solution to run down the electrode and wet the electrical contacts in
the DryLoc connector.
6
. Slowly screw on the membrane cap
fi
nger tight. Do not use tools.
To avoid damage and contamination, do not touch the white membrane
surface on the membrane cap.
