Safety Precautions - ProMinent DULCOMETER PH-501 Assembly And Operating Instructions Manual

SAFETY PRECAUTION
About Manual: PLEASE READ THE ENTIRE MANUAL PRIOR TO INSTALLING OR USING THIS PRODUCT. This
manual includes information on all models of Flowline Switch Tek™ Powered Level Switches: LZ12, LU10, LP15
and LO10 series. Please refer to the part number located on the sensor label to verify the exact model which
you have purchased.
User's Responsibility for Safety: FLOWLINE manufactures a wide range of liquid level switches and
technologies. While each of the these switches are designed to operate in a wide variety of applications, it is
the user's responsibility to select a switch model that is appropriate for the application, install it properly,
perform tests of the installed system, and maintain all components. The failure to do so could result in
property damage or serious injury.
Proper Installation and Handling: Because this is an electrically operated device, only properly trained staff
should install and/or repair this product. Use a proper sealant with all installations. Note: Always install the
3/4" Viton gasket with all versions of Switch Tek™ with metric threads. The G threaded version will not seal
unless the gasket is properly installed. Never over tighten the sensor within the fitting, beyond a maximum of
80 inch pounds torque. Always check for leaks prior to system start up.
Material Compatibility: The LU10 and LO10 series sensors are available in two different wetted materials.
Models L_10 1__5 are made of Polypropylene (PP). Models L_10 2__5 are made of Perfluoroalkoxy (PFA).
The LZ12 series is made of made of Ryton® (40% glass filled) and the LP15 series is made of PP. Make sure
that the model you have selected is compatible with the application liquid. To determine the chemical
compatibility between the sensor and its application liquids, refer to an industry reference such as the
Compass Corrosion Guide (available from Compass Publications, phone 858 589 9636).
Wiring and Electrical: The supply voltage used to power the sensor should never exceed a maximum of 36
volts DC (30 VDC for LZ12 series). Electrical wiring of the sensor should be performed in accordance with all
applicable national, state, and local codes.
Flammable, Explosive and Hazardous Applications: Only the LU10 ___5 series switch is rated for use in
hazardous locations. Refer to the Certificate of Compliance for all applicable intrinsically safe ratings and
entity parameters. Refer to the National Electric Code (NEC) for all applicable installation requirements in
hazardous locations. DO NOT USE THE LZ12, LP15 OR LO10 SERIES GENERAL PURPOSE SWITCH IN
HAZARDOUS LOCATIONS.
The rating for the relay is 60 VA (125 VAC max / 1A max).
Flowline's Switch Tek™ level switches are not recommended for use with electrically charged application
liquids. For most reliable operation, the liquid being measured may need to be electrically grounded.
Always install the 3/4" Viton gasket with all versions of the powered sensors with metric threads. The G
threaded version will not seal unless the gasket is installed properly.
