Maintenance
Inspection of the lamp may reveal a layer of contamination on the detection window that presents itself as a
‘blue hue.’ To check for confirmation, hold the lamp in front of a light source and look across the window
surface. Clean the window using the PID Lamp Cleaning Kit (A-31063) supplied.
USE of PID Lamp Cleaning Kit A-31063
The container of cleaning compound contains Aluminium Oxide as a very fine power
(CAS Number 1344-28-1).
A full material safety data sheet MSDS is available on request from Ion Science Ltd. The key issues are
listed below:
Always replace the lid after using the cleaning compound.
Hazard identification:
•
May cause irritation of respiratory tract and eyes.
Handling:
• Do not breathe vapor / dust. Avoid contact with skin, eyes and clothing;
•
Wear suitable protective clothing;
•
Follow industrial hygiene practices: Wash face and hands thoroughly with soap and water after
use and before eating, drinking, smoking or applying cosmetics;
• The Compound has a TVL (TWA) of 10 mg/m3.
Storage:
• Keep container closed to prevent water adsorption and contamination.
To clean the lamp:
1.
Open the vial of Aluminium Oxide polishing compound. With a clean
cotton bud collect a small amount of compound;
2. Use this cotton bud to polish the PID lamp window. Use a circular
action applying light pressure to clean the lamp window. Never touch
the lamp window with fingers;
3. Continue polishing until an audible “squeaking” is made by the cotton
bud with compound moving over the window surface (usually within
fifteen seconds);
4. Remove the residual powder using the clean end of the cotton bud.
5.
To refit the lamp, lay the electrode stack on its back and inserting the
lamp into the stack while lightly twisting.
6. Lower the PID body over the electrode stack / lamp assembly. When
located press down until the electrode stack clips into place.
