Installation
WARNING
D Wear protective clothing, gloves, and eyewear whenever possible when performing any installation operations to
avoid personal injury or property damage.
D To avoid personal injury or property damage caused by the sudden release of process fluid, be certain the service
conditions do not exceed the sensor pressure limits. Use pressure‐limiting or pressure‐relieving devices to prevent
service conditions from exceeding these limits.
D Personal injury or property damage may result from fire or explosion if natural gas is used as the supply medium and
preventive measures are not taken. Preventive measures may include, but are not limited to, one or more of the
following: Remote venting of the unit, re‐evaluating the hazardous area classification, ensuring adequate ventilation,
and the removal of any ignition sources. For information on remote venting of this controller, refer to page 7.
D If installing this into an existing application, also refer to the WARNING at the beginning of the Maintenance section of
this instruction manual.
D Check with your process or safety engineer for any additional measures that must be taken to protect against process
media.
CAUTION
If the L2sj low emission liquid level controller is installed on a vessel that is to be shipped to a different location (e.g. skid
mounted units), remove the displacer and displacer rod extensions before shipment. Failure to do so could result in
damage to the displacer rod due to vibration and impact loading during shipment. After the vessel is installed at its final
location, reassemble the displacer and displacer rod extension.
1. Be sure there are no obstructions inside the vessel that will interfere with displacer installation or operation.
2. Provide the appropriate connection in the vessel wall to match the sensor connection. Locate the vessel connection
so that the displacer will be at the desired control level.
