Routine Maintenance
The only regular maintenance needed by HC5-10, is the periodic substitution of the
blowers, and the cleaning of dust filters and any dust accumulated inside the amplifier.
The time between overhauling of the blowers depends upon several environmental
factors, temperature, humidity, dust pollution etc.
It’s advisable to check the unit every 6 months, and to substitute noisy blowers.
Blowers should be changed as a matter of course at least not beyond the 35000
hours of job.
