3.0 Pre-Installation Instructions 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. Refer to MSDS precautions from your solution supplier. Water Pre-Prime All LMI pumps are pre-primed with water when shipped from the factory. If your solution is not compatible with water, disassemble the Pump...

Fittings And Machine Threads All fittings should be hand-tightened. An additional 1/8 - 1/4 turn after the fitting contacts the seal ring 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. All LMI pumps have straight screw machine threads on the head and fittings and are sealed by the seal rings or O-rings. DO NOT use Teflon® tape or pipe dope to seal threads. Teflon® Tape may only be used on the 1/2" NPT thread side of the Injection Check Valve as well as stainless steel liquid end...

Electrical Connections To reduce the risk of electrical shock, install only on a circuit protected by a ground-fault circuit-interrupter (GFCI). The metering pump must be plugged into a grounded outlet with ratings conforming to the data on the pump control panel. The pump must be connected to a good ground. DO NOT USE ADAPTERS! All wiring must conform to local electrical codes. WARNING: Do not hook a US style pump plug into a non-US (UK, Aust, NZ or Swiss) wired power system. The US style 240VAC power system has two 110VAC hot legs and one neutral. The European style system has one 240VAC...

Flooded Suction The pump is mounted at the base of the storage tank. This installation is the most trouble-free , and is recommended for very low outputs, solutions that gasify, and high-viscosity solutions. Since the suction tubing is filled with solution, priming is accomplished quickly and the chance of losing prime is reduced. When pumping downhill or into low or no pressure system, a back pressure/anti-syphon device should be installed to prevent overpumping or syphoning. Although popular for all solutions, LMI recommends flooded suction installations for all high-viscosity fluid...

Suction Lift - Wall Bracket Mount The pump may be mounted using an LMI Wall Mount Bracket Assembly (part no. 34643) directly above the solution tank. A pump mounted in this manner allows for easy changing of solution tanks or drums. Tee Injection Check Valve LMI Pump Rear Mount LMI Pump Front Mount Solution Tank 2.0 in.
