Special Conditions for safe use:
On devices supplied with 4-inch floats: to avoid build-up of static charge, do not rub with a dry cloth or clean in
any manner that would result in a charge build-up. Discharge the probe outside of the hazardous area before
putting it into service.
These devices have not been evaluated for use across a boundary wall.
The upper housing cover in the top of the enclosure is aluminum. Care must be taken to avoid ignition hazards
