3.6 Inlet Port Maintenance
The inlet port must be kept clean at all times. The port incorporates a
stainless steel mesh that stops dust and lint from entering the sensor
head. In dusty environments, this mesh can become blocked with dust
and lint. Remove dust and lint manually. Replacement mesh filters are
available.
