5.3 Cleaning
Milltronics MFA 4p
24 Operating Instructions, 08/2017, A5E33988839_AB
If it is necessary to clean the enclosure and circuit boards:
1. First, make sure the power is disconnected at the main breaker.
2. Use a vacuum cleaner and a clean, dry paint brush.
3. Check all electrical contacts for corrosion and arcing.
It is a good idea to periodically check the face of the probe: it should be free of material
buildup, corrosion or deformation.
The Motion Failure Alarm MFA 4p requires no maintenance: however, we recommend a
program of periodic checks.
