Maintenance
5.3 Vacuum detector
Fig.32
First, vacuum or blow off any loose debris on the outside of cover. Then remove the detector cover and screen
assembly by rotating a flat screwdriver in slot (both sides) and pulling it straight up. Cover may be difficult to
remove the first time.
Vacuum all areas illustrated below, and then blow off same areas with compressed air. Before reassembling
the detector, be sure all parts are free of debris.
5.4 Final steps
Replace cover and screen assembly.
Measure and record test voltage at test points RP1 & RP2. If the product is operating normally, and was
cleaned effectively, the test voltage will be less than the voltage recorded earlier. (Typical voltage for a clean
device is .9 - 1.58 Vdc.)
