ROUTINE MAINTENANCE
There is routine maintenance that should performed on a periodic basis to prevent the unit from degrading in performance and cosmetic condition. Clean the exterior with a soft, lint-free cloth. Do not use alcohol, benzene, acetone-
based cleaners, or strong commercial cleaners. If the unit is exposed to a dusty environment, you can use a vacuum with a brush attachment to suck all dust and debris from the unit. Even a low pressure air compressor can be used to
remove dust from its exterior surface. Any cleaning or dusting should be done externally, preventatively.
