WARNING!
For your safety, all the information in this User’s Guide must be
followed to minimize the risk of electrical shock and prevent
property damage or personal injury.
WARNING!
Extreme care should be exercised to avoid contact with live
electrical circuits. Many procedures performed during installation,
operation, testing, and maintenance of this air-dryer require the
equipment to be running, creating a situation for potential electrical
shock. It is highly recommended that you remove all jewelry before
