5.3.4 PA Module Cleaning Procedure
The PA module heatsinks are designed for high efficiency and therefore do not have
large openings for airflow. As a result, it is common for the modules to collect dirt over
time. The modules should be cleaned with compressed air on a schedule to be
determined on site, depending on the air system, filtering, humidity etc. (at least once a
year).
THE PA MODULES ARE DESIGNED TO HANDLE VERY HIGH TEMPERATURES AND
MAY BE EXTREMELY HOT. DO NOT TOUCH THE MODULE SIDES WITH BARE
HANDS AFTER THE TRANSMITTER HAS BEEN RUNNING, ESPECIALLY IN HIGH
AMBIENT TEMPERATURE ENVIRONMENTS.
Tools required:
Air compressor or
Vacuum cleaner with hose & nozzle attachment
Dry paintbrush
STEP 1 Remove PA module from transmitter.
DO NOT ATTEMPT TO THE CLEAN PA MODULES WITH COMPRESSED WHILE
THEY ARE STILL INSTALLED IN THE TRANSMITTER. THIS WILL FORCE DUST
DEEPER INTO THE TRANSMITTER.
