The FT7000 has few parts that will require regular maintenance, however it is important to service
annually to extend the life of the monitor. Unsheltered units should be serviced in dry weather to
prevent rainwater from entering the enclosure and minimize moisture exposure.
1.
Once the unit has been powered down and hazardous gases have dissipated, remove the 12 lid
screws.
2.
Open the lid, then verify the O-ring gasket is in good condition and secured into the O-ring track.
If the O-ring is loose or damaged, replace and secure using ordinary superglue.
3.
Inspect the interior of the enclosure for condensation or pooled water. The presence of water
will cause corrosion and/or failure and should be fixed immediately.
If water or condensation is present, replace O-ring, inspect cable entry threads and reapply
corrosion inhibiting grease if needed. For conduit installations, verify the conduit-sealing fitting
is filled. For non-conduit installations, verify the cable gland is tightened properly to seal against
the cable jacket. If necessary, add sealing compound to fortify water tight seal. Re-inspect after
next rain to ensure water has not entered the enclosure. If water still enters enclosure, contact
Dixon support for further assistance.
