Product must be maintained and
installed in strict accordance with the
National Electrical Code and GEMS product catalog and instruction bulletin. Failure to observe this warning could result in
serious injuries or damages.
An appropriate explosion-proof enclosure or intrinsically safe interface device
must be used for hazardous area applications involving such things as
ited to)
ignitable mixtures, combustible dust
and flammable materials.
Pressure and temperature limitations
shown on individual catalog pages and
drawings for the specified flow switches
must not be exceeded. These pressures
and temperatures take into consideration
possible system surge pressures/temperatures and their frequencies.
Selection of materials for compatibility
with the media is critical to the life and
(but not lim-
operation of GEMS flow switches. Take care
in the proper selection of materials of construction; particularly wetted materials.
Life expectancy of switch contacts varies with
applications. Contact GEMS if life cycle testing is required.
Ambient temperature changes do affect
switch set points, since the specific gravity of
a liquid can vary with temperature.
Flow switches have been designed to resist
shock and vibration; however, shock and vibration should be minimized.
Liquid media containing particulate and/or
debris should be filtered to ensure proper operation of GEMS products.
Electrical entries and mounting points may
require liquid/vapor sealing if located in an enclosed tank.
Flow switches must not be field repaired.
Physical damage sustained by the product
may render it unserviceable.
All plastic NPT threads should be installed using a suitable thread sealant.

Tests Conducted with Units in a Horizontal Position
This product is suitable for Class I and Class II applications only, per the
requirements of standard EN60730 and any additional specific requirements for
a particular application or medium being sensed. Class I compliance of metal
bodied units requires a ground connection between the metal body and the
earthing system of the installation. Class I compliance of plastic bodied units in
contact with a conductive medium requires that the medium be effectively
earthed so as to provide an earthed barrier between the unit and accessible
areas. For Class III compliance, a supply at safety extra-low voltage (SELV)
must be provided. Please consult the Factory for compliance information on
specific part numbers.
