Section 10: Routine maintenance
This section provides instructions for performing routine maintenance on the Importer Plus. This
section includes the following topics:
• Checking the fans - see page 10-1
• Cleaning the fan filter - see page 10-2
Checking the fans
The Importer Plus contains three operational cooling fans (see Figure 2.4 on page 2-6). In order to
maintain your Importer Plus warranty and prevent premature component failures, check the fans
periodically.
Interval
• Every six months in typical environments.
• Every three months in dusty, humid or harsh environments.
Procedure
Take the following steps to check the fans:
1. Remove the Importer Plus’ top cover. If possible, allow the Importer Plus to continue
normal operation.
2. Verify that the three cooling fans are turning at an acceptable speed and that there are no
visible obstructions.
3. If you need to closely inspect a fan, clear an obstruction, or replace a fan, you must turn off
the Importer Plus. You should also remove the ac power connection at the back of the
Importer Plus.
