MAINTENANCE
The following routine maintenance should be performed on a
periodic basis:
• Clean the exterior surfaces of the unit with a soft, dry, lint-free
cloth. Do not use alcohol, benzene, acetone-based cleaners, or
strong commercial cleaners. Do not use a cloth made with
steel wool or metal polish. If the unit is exposed to a dusty
environment, a low-pressure blower may be used to remove
dust from its exterior.
