The SOR
®
1510 Level Switch mounts into the side of a vessel. Electric switching action is
provided by the float moving a magnet into the field of a hermetically sealed reed switch
capsule.
The unit may be mounted for either high or low liquid level alarm by rotating the switch
body to the proper position. The body wrench flats provide for ease of rotation and proper
positioning. See decal on housing.
Before Installation of the Level Switch:
Inspect the unit for any shipment damage.
Check for mechanical clearance of
the float. Float must move freely without binding throughout its stroke.
Use an acceptable thread compound when installing unit to ensure a leak-free fit and to
avoid thread galling.
To achieve required function, install the unit according to the nameplate instructions
shown here.
NOTE: If you suspect that a product is defective, contact the factory or the SOR Representative
in your area for a return authorization number (RMA). This product should only be installed by
trained and competent personnel.
