Maintenance
The amount of humidity and quality of the ambient air will directly affect the time between servicing.
WARNING:
Leaving contamination on the lamp window can cause irrecoverable damage to the PID Lamp.
7.
The Electrode Stack should be inspected for visible signs of contamination, if contamination can be
seen the Stack it must be replaced. (The Electrode Stack part number 1/EA-02)
Reassembly:
8.
Place the clean PID Lamp into the PID Cell avoiding finger contact with the Window.
9.
Refit the Electrode Stack with the electrical pin holes and electrode wire racing down.
10.
Refit the Metal Spring Cover.
11.
Ensure the Electronic
Pins of the PID Cell are at
the 12 o’clock position
before inserting the PID
Cell.
The PID Cell should insert
into the connectors easily,
if significant resistance is
felt, remove the cell and
check alignment before
reinserting.
WARNING:
Irreparable damage will be caused by forcing the PID into the Sensor Holder if not correctly aligned.
NOTE: Always calibrate TVOC after servicing is carried out.
