7.5 Replacing the Filters

NOTE:
When replacing external dust and water filters, prevent any dust or dirt around the filter
housing from entering the PID sensor. Dust or dirt entering the PID sensor may impede
or degrade PID sensor performance, especially in humid environments. Also, dust or dirt
that gets pulled into the pump unit may impede pump operation.
DUST AND WATER FILTER
1. Turn OFF the instrument and, while in a non-hazardous and non combustible area,
remove the battery pack.
2. Unscrew the captive screw from the clear filter housing on the back of the instrument
to access the filters.
