12. Maintenance
12.1. Cleaning
The exterior of this power supply may be cleaned using a damp cloth and a water/detergent
solution.
Clean air inlet and air exit as needed to prevent build up of debris using compressed air or a
vacuum.
Do not allow an excess build up of dust and debris to accumulate on the unit as the power supply
may run hotter and signal and over-temperature alarm or go into standby mode.
Failing to follow cleaning and maintenance procedures may void the warranty and reduce the life
of the power supply.
12.2. Filter Replacement (if equipped)
Turn off power supply. Unsnap black filter cover located on the back of the power supply, remove
cover and foam filter. Do not remove the four fan guard screws. Discard foam filter and replace
with a new foam filter. Ensure foam filter is properly seated in cover. Snap cover and foam filter
back onto power supply. Failure to use a Dynatronix supplied filter may reduce the life of the
power supply and void the warranty.
