INTRODUCTION

This section contains periodic maintenance and performance test information for the C7

Series. It also contains a list of test equipment required to perform various tests.

NOTE:

Check your sales order and equipment warranty before attempting to service

or repair the unit. Do not break the seals on equipment under warranty or the

warranty will be null and void. Do not return equipment for warranty or repair

service until proper shipping instructions are received from the factory.

5.3.

CLEANING AIR INLETS/OUTLETS

The air inlets and outlets should be checked every 30 days and cleaned if necessary. If the

equipment is operated in a severe dust environment, it should be checked and cleaned

more often. If dust and dirt are allowed to accumulate, the cooling efficiency will be

diminished. Using either compressed air or a brush with soft bristles, loosen and remove

accumulated dust and dirt from the air inlet panels.

Check that the fan is running smoothly. A slow running or noisy fan may indicate an

imminent fan failure. Replace immediately with a similar to insure long term reliability.

Heat is one of the biggest factors in reducing the reliability of your amplifier. Make sure the

fan has access to cool and clean airflow within the rack.
