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. Refer to Safety Data Sheets 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 Head Assembly. Thoroughly dry the pump
head, valves, seal rings, balls and LIQUIFRAM™ DIAPHRAGM. Reassemble head assembly
tightening screws in a crisscross pattern. Rell the pump head with the solution to be pumped
before priming the pump. (This will aid in priming.)
Liquid Compatibility
CAUTION: The evaluation performed by UL was tested with water only. LMI pumps are
EC1783 certied for NSF / ANSI Standard 61 and 372. Please check our listings with NSF
International to conrm approved chemicals and concentrations for use. Always refer to the
solution supplier and the LMI®Chemical Resistance Chart for compatibility of your specic
LMI®metering pump. Contact your local LMI®distributor for further information.
Tubing Connections
Inlet and outlet tubing or pipe sizes must not be reduced. Outlet tubing size must not be
increased. Make certain that all tubing is SECURELY ATTACHED to ttings prior to start-up
(see Section 2.3, Tubing Connections). ALWAYS use LMI®supplied tubing with your pump,
as the tubing is specically designed for use with the pump ttings. It is recommended that
all tubing be shielded and secure to prevent possible injury in case of rupture or accidental
damage. If tubing is exposed to sunlight, black UV resistant tubing should be installed. Check
tubing frequently for cracks and replace as necessary.
Vinyl Tubing
Your carton may contain a roll of clear vinyl tubing; this is only for connection to the return line
of the FASTPRIME™ Head and must not be used as discharge tubing.
Ground Fault Circuit Interrupter
WARNING: To reduce the risk of electric shock, install only on a circuit protected by a Ground
Fault Circuit Interrupter (GFCI).
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.

iii Instruction Manual
Fittings and Machine Threads
All ttings should be hand-tightened. An additional 1/8 - 1/4 turn after the tting is snug may
be necessary to provide a leak-proof seal. Excessive over tightening or use of a pipe wrench
can cause damage to the ttings, seals, or pump head. All LMI®pumps have straight screw
machine threads on the head and ttings and are sealed by the O-rings. DO NOT use PTFE
tape or pipe dope to seal threads. PTFE Tape may only be used on the 1/2” NPT thread
side of the Injection Check Valve, the stainless steel liquid end connections, or if
piping is directly connected to the pipe threads of the suction or discharge ttings.
Plumbing
Always adhere to your local plumbing codes and requirements. Be sure installation does
not constitute a cross connection. Check local plumbing codes for guidelines. LMI®is not
responsible for improper installations.
Back Pressure / Anti-Syphon Valve
If you are pumping downhill or into low or no system pressure, a back pressure / antisyphon
device such as LMI®’s Four-Function Valve (4-FV) should be installed to prevent over
pumping or syphoning. Contact your LMI®distributor for further information.
Electrical Connections
WARNING: To reduce the risk of electrical shock, the metering pump must be plugged into
a properly grounded grounding-type receptacle 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. If the supply cord is damaged, it must be
replaced by the manufacturer, stocking distributor, or authorized repair center in order to
avoid a hazard.
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.
Chemical Concentration
There is a potential for elevated chemical concentration during periods of no ow, for
example, during backwash in the system. Steps, such as turning the pump OFF, should be
taken during operation or installation to prevent this. See your distributor about other external
control options to help mitigate this risk.
Retightening Components
Plastic materials will typically exhibit creep characteristics when under pressure over a period
of time and to insure a proper t it may be necessary to retighten the head bolts periodically.
To insure proper operation, we recommend tightening the bolts to 25 inch pounds during
installation after the rst week of operation and on a monthly basis thereafter.
