Simple maintenance can be performed by the user
to help keep the equipment operational. The fol

lowing routine maintenance is designed to prevent
problems before they occur. See the
Trouble -

section, for recommendations for re-
storing the equipment to operation after an error
condition has occurred.
Preventative maintenance is recommended after
the first 250 hours of operation, and every three
months or 250 hours thereafter. If the equipment
environment is dirty or dusty, preventative mainte

nance should be performed more frequently.

To ensure adequate cooling and maximum ef -
ficiency of the internal cooling fans, the amplifier’s
front and rear grills should be cleaned periodically.
To clean the amplifier grills and filter, complete the
following steps:
1. Disconnect the amplifier from its power source
via external mechanical disconnect or breaker.
2. The front grill is secured to the amplifier front
panel by magnets. Pull out on the grill to re
-
lease it from the front panel.
3. Remove the filter located behind the front grill.
4. Using a vacuum cleaner, vacuum the front ven -
tilation grill, the grill filter, and the back ventila -
tion exit grill.
5. Using a damp cloth, clean the amplifier front
panel and the rear ventilation grills. Also use
the damp cloth to clean the front grill and filter.
If necessary, these can be immersed in warm,
soapy water.
6. Dry the front panel, filter, and grills with a clean
cloth or allow to air dry. IMPORTANT: All parts
should be completely dry before reconnect -
ing or restarting the amplifier.
7. Reinstall the filter and replace the amplifier
front grill.
Before you begin, make sure your ampli-
fier is disconnected from the power
source. The amplifier’s AC input must be
completely disconnected from the power
source via external mechanical discon -
nect or breaker.
