VS300 Operations and Maintenance Manual Routine maintenance
Issue 10.0 2019-01-18 Page 3-1
Section 3: Routine maintenance
This section provides instructions for performing routine maintenance on the VS300
transmitter. This section includes the following topics:
• Scheduled maintenance
– Cleaning fan filters - see page 3-1
– Checking hardware - see page 3-2
– Battery replacement - see page 3-2
• Performing on-air checks - see page 3-3
• Replacing the exciter/control PWB battery - see page 3-4
Scheduled maintenance
Scheduled maintenance consists of performing a visual inspection of the VS300 at scheduled
intervals. The recommended minimum time between scheduled maintenance visits is 12
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 fan filters
Clean the fan filters, noting there is one on each side of the transmitter. Gently remove the fan
filter cover and guard, rinse the filters with water, then re-install the filters and guards. If a fan
filter becomes damaged, replace it as soon as possible. You can order the filter from Nautel
(part # HAS72) or obtain one from any local supplier of HVAC supplies.
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.
