Valve seat adjustment can be made if air/gas begins to leak. Care should be taken
when adjusting as only slight movement is necessary to stop the leakage; excessive

CAUTION: Avoid excessive Teflon tape which may inhibit proper
operation.
Trip Cam Operating Lever Orientation
The LS200 series level switches are shipped with the trip cam orientation set for normal
operation, or vent on rising level. If the application requires a vent on falling level, the trip cam
operating lever can be moved to the alternate position as indicated in the diagram below.
Gently depress the cam and rotate to the other lever position. Make sure the cam returns to
the full height position with the cam lever resting fully in the grove.
