- Page 3 PRECAUTIONS The following precautions should be taken when working with LMI metering pumps. ® Please read this section carefully prior to installation. Protective Clothing ALWAYS wear protective clothing, face shield, safety glasses and gloves when working on or near your metering pump. Additional precautions should be taken depending on the solution being pumped.
- Page 4 Fittings and Machine Threads All fittings should be hand-tightened. An additional 1/8 - 1/4 turn after the fitting is snug may be necessary to provide a leak-proof seal. Excessive overtightening or use of a pipe wrench can cause damage to the fittings, seals, or pump head. Most LMI pumps have straight screw machine threads on the head and fittings and are ®...
- Page 5 Line Depressurization To reduce the risk of chemical splash during disassembly or maintenance, all installations should be equipped with line depressurization capability. Using LMI ’s Four-Function Valve ® (4 FV) is one way to include this feature. Over Pressure Protection To ensure safe operation of the pump it is recommended that some type of safety/pressure relief valve be installed to protect the piping and other system components from failing due to excessive pressure.
