The fans used by CEFD's LPOD family of Outdoor Amplifiers / BUCs (Figure C-1) are designed
for long life, even in harsh environments. Still, they are mechanical devices, subject to wear, and
may need replacement after several years.
In most environments, CEFD recommends clearing the heat sinks of dust and debris
approximately once per year to ensure optimal fan life. This appendix outlines the procedures for
uninstalling the LPOD PD 1, PS 1.5, or PS 2 fan shroud, inspecting and cleaning the heat sinks,
and then re-installing the fan shroud.
Use the temperature trending data, available from the LPOD HTTP Interface 'Status | Trending
Graphs' page (Figure C-2 ) as a guide to determine if more or less frequent preventative
maintenance is required.
