CAUTION
Improper handling of device components can damage the Series 3000
device.
If a breaker bar or other tool is used for loosening the cover of the circuit board
compartment:
• Apply steady pressure to avoid chipping the paint. Chipped paint can result in
corrosion of the housing. If the paint is chipped, repaint the housing.
• Do not apply excessive torque. Excessive torque can damage the pipeline or the
