5. MAINTENANCE
The Combiner does not need internal maintenance as it has a cover without ventilation
holes. As high voltage tubes are not used, the natural attraction of dust is eliminated.
Therefore, the user only needs to periodically check and clean the air filter on the front
panel.
The frequency of air filter inspection depends on how dusty the location is, and how
much it is used. We recommend monthly cleaning of the filter.
Twice yearly cleaning of the fans with a soft brush is also recommended.
To clean the filter:
a)
Remove the front grid cover with the two small screws.
Place small screws in a secure place. DO NOT LOSE THEM.
b)
Remove the filter and clean it with care.
c)
Reassemble the filter and the grid after having carefully cleaned the
mechanical structure that holds them. Dry filter before re-installing.
Note: Check the filter if an unexpected rise of temperature of the Combiner is noticed.
Note: Never operate without the filter, as dust could be deposited on the surface of the
heatsink limiting its ability to cool.
Note: To allow the most efficient heat dissipation of the Combiner circuits, large copper
parts have been used.
