Occasionally the Fido X4 system can become dirty or contaminated with residue or envir-
onmental contaminants. The Clean System menu provides instructions on how to clean the
Fido X4 to ensure optimal performance throughout operation. There are two types of clean-
ing covered on this menu.
8.6.1.1 Power clean
Power clean is the fastest option for cleaning the sensor inlet. Power clean is an automated
function that elevates the exterior and interior temperature of the inlet to volatilize and
remove residual contamination. This process takes about 7 minutes from start to finish and
will require you to install a new sensing element once completed. For more information, see
"Replacing the Sensing Element" on p. 53.
8.6.1.2 Manual cleaning
Periodically, the Fido X4 should be cleaned manually. The manual cleaning frequency and
schedule will depend on your operational environment and throughput; however, a general
guideline is to perform manual cleaning once per week during periods of moderate to heavy
usage.
FLIR recommends that manual cleaning be performed at the beginning or end of system
operation to avoid disruptions in operational throughput.
The Clean System menu gives you access to two video tutorials on manual cleaning:
• Clean Inlet and Desorber
• Fix a Clogged Inlet
