Scheduled Maintenance
Scheduled maintenance consists of performing a visual inspection of the NV30LT-N at scheduled
intervals. The recommended minimum time between scheduled maintenance visits is three months.
Local operating and environmental conditions may dictate more frequent visits, while in remote sites
less frequent visits may be acceptable. Experience and system reliability will determine the most
practical schedule for a specific installation.
Cleaning
At a minimum, follow the cleaning procedures listed below.
NOTE
: A site located in a dirty area using open-air cooling requires more extensive cleaning than a site
located in a clean area using closed-air cooling.
1. Check the air filters, noting there is one in the front of the transmitter and one in the back of the
transmitter. Remove the air filters, inspect them, then re-install the air filters if they are clean. If an
air filter is dirty or damaged, replace it as soon as possible. See
“Replacing an Air Filter” on
page 3.3.3 .
