Chamber Cleaning
Cleaning or replacing of the chamber cover should only be
carried out by suitably trained personal.
1. Remove the Detector from the mounting plate.
2. Remove the battery or batteries.
3. With a flat screwdriver unclip the three cover clip points (see
figure 9a).
4. Remove the cover (see figure 9b).
5. If the unit is a model containing a thermistor you will need
to unplug the thermistor by holding the thermistor PCB and
pulling the pins out of the sockets (see figure 9c).
6. To remove the chamber top turn the chamber anti-clockwise
approx. 15 degrees (see figure 9d).
7. Blow out or use a soft bristled brush to remove dust and dirt
from the chamber base.
8. Fit a new chamber top and clip in place by turning clock-wise
15 degrees.
9. Insert the thermistor PCB into the sockets and ensure the
thermistor is perpendicular to the chamber (see figure 9e).
10. Place the cover back on the Detector taking care to ensure
the thermistor is protruding through the cover (see figure 9f).
11. Replace the battery / batteries and reattach to the mounting
plate.
