Cleaning or Replacing the PID
Note: The cleaning procedure is not normally needed. Clean the PID sensor module, the lamp
and the lamp housing only when one of the following has happened:
1.
The reading is inaccurate even after calibration.
2.
The reading is very sensitive to air moisture.
3.
A chemical liquid has been sucked into the unit and damaged the unit.
Use of the external filter helps to prevent contamination of the sensor.
Cleaning or Replacing the 4R+ PID
1.
Gently lift out the PID module with your fingers.
2.
If the module requires replacement (because the lamp does not illuminate, or the module
has been used past its expiration date), place a new module into the slot, being careful to
match the indexing keys. The sensor can only go into its slot one way. Refer to step 11 for
alignment information.
3.
If you want to open the sensor module to inspect and clean the lamp and sensor
electrode panel, you must use the special tool (P/N: G02-0306-003). The special tool's
"C"-shaped end has small "teeth" inside. Slide the tool so that the teeth slip into the notch
between the module's cap and body:
4.
Gently pry up the cap using a rocking motion:
