Cleaning the Fan Filters

From time to time, it may become necessary to clean the fan filter.

It’s a good idea to keep the fan filter clean to ensure maximum

airflow, and cooling, through your LH Series amplifier. To clean the

fan filters, follow these simple steps:

1/ Remove the fan filter by placing your finger in the depressed

area under the fan filter frame.

2/ Clean the filter with warm water and let the filter dry thoroughly

before replacing.

3/ Replace the fan filter by aligning the frame to the top of the

panel knock-out, and then, snap the frame back in place.
