General Information
1. Switches should be installed rigidly so the float or floats are free to move as the liquid level changes.
2. Switches should be mounted in a tank area free of severe turbulence or protected from such turbulence by
appropriate and adequate slosh shields.
3. Vertical switch stems should be vertical for best results, but satisfactory operation is possible in most liquids
with the stem at up to a 30˚ angle from vertical.
4. Care should be taken that switches are always operated within electrical ratings.
5. Orientation for standard Vertical switches can be changed from normally open to normally closed dry or vice
versa by removing the float and reversing it in the stem, except with the LVM-41J, LVM-41K, and LVM-43R.
Cautions
1. The pressure, temperature and electrical
limitations shown for the specified level
switches must not be exceeded.
2. The pressures and temperatures must take
into consideration possible surges in the
temperature and pressure of the system.
3. The liquids used must be compatible with
the materials of construction. Specifications
of materials will be given upon request.
4. Life expectancy of the switch varies with
applications.
5. Ambient temperature changes can affect
switch set points, since specific gravities of
Maintenance
Maintenance should consist of inspection
to see that the float is free to move and
not coated with any substance, which
would change its weight or volume
significantly. If this occurs, the float
should be cleaned. This is easily
accomplished without disturbing the
installation. In addition, the stem may be
wiped down to remove any build-up.
The only repair possible in the field is
replacement of either the float or stem.
Dents or nicks on the float are usually of
no consequence to operation.
Installation
Operation is stated in the tank dry position.

liquids vary with temperature. Consult
factory for assistance.
6. Level switches have been designed to be
shock and vibration resistant. For maximum
life, both shock and vibration should be
minimized. Consult factory for assistance.
7. Excessive contaminants in fluid may inhibit
float operation, and occasional wipe down
may be necessary.
8. Level switches must not be field repaired
9. Physical damage to product may render
product unserviceable.
10. Installation in a vessel made from magnetic
materials may affect operation.
Vertical Switches:
NC Operation: SS Floats: Witness mark (round circle) down.
Plastic Floats: Magnets up.
NO Operation: SS Floats: Witness mark (round circle) up.
Plastic Floats: Magnets down.
Typical Current and Voltage Ratings
* Note: The ratings at

loads only. For
inductive loads,
maximum switch life
will be achieved if
appropriate arc
suppression is used.
