Replacing the Air Filter in the Housing Base

1.

Remove the four screws from the detection module using a screwdriver and pull the 

detector module out of the housing base.

2.

Pull both filter brackets out of the housing base and remove the filter inserts. Carry out a 

visual check for contamination and replace the filter if necessary. Then put the filter 

bracket back into position.

3.

Retighten the four screws on the detector module using a screwdriver.
