User's Responsibility for Safety:
KOBOLD manufactures a wide range of
process sensors and technologies. While each of these technologies are
designed to operate in a wide variety of applications, it is the user's
responsibility to select a technology that is appropriate for the application,
to install it per these installation instructions, to perform tests of the
installed system, and to maintain all components. The failure to do so could
result in property damage or serious injury.
•
Proper Installation and Handling:
Use a proper sealant with all
installations. Never overtighten the unit within the fitting.
Never use the
housing to thread the unit into its fitting
. Always use only an
appropriate sized wrench on the hex portion of the probe. Always check for
leaks prior to system start-up.
•
Wiring and Electrical:
A supply voltage of 24 Volts AC or DC +10%/-15%
is used to power the KAL-L. The sensor systems should never exceed this
rating. Electrical wiring of the sensor should be performed in accordance
with all applicable national, state, and local codes.
•
Temperature and Pressure:
The KAL-K is designed for use in application
temperatures from -10 to 250°F, and for use at pressures up to 115 PSIG.
Operation outside these limitations will cause damage to the unit and
possible personal injury.
•
Material Compatibility:
The KAL-K sensor probe is made of nickel plated
brass. The housing is polycarbonate. Check your model number with the
wetted materials specification in Section 2.0 ‚"Specifications”, on page 1 of
this manual. Make sure that the model which you have selected is
chemically compatible with the application environment. While the switch
housing is liquid resistant when installed properly, it is not designed to be
immersed. It should be mounted in such a way that it does not normally
come into contact with liquid.
•
Flammable, Explosive and Hazardous Applications:
The KAL-L is not
an explosion-proof or intrinsically safe design. It should not be used in
hazardous areas where risk of explosion exists.
•
Make a Fail-safe System:
Design a fail-safe system that accommodates
the possibility of switch or power failure as well as operator error. In critical
applications, KOBOLD recommends the use of redundant backup systems
and alarms in addition to the primary system.
