Instruction Manual
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 SDS 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. Refill the pump head with the solution to be pumped
before priming the pump. (This will aid in priming.)
Liquid Compatibility
The evaluation performed by UL was tested with water only. LMI
®
pumps are tested to NSF
50 for use on muriatic acid (40%) and sodium hypochlorite (12.5%). The pumps are certified
to NSF 61 with: sodium hypochlorite (12.5%), sulfuric acid (98.5%), sodium hydroxide (50%),
and hydrochloric acid (30%). Determine if the materials of construction included in the liquid
handling portion of your pump are adequate for the solution (chemical) to be pumped. Always
refer to the solution supplier and the LMI
®
Chemical Resistance Chart for compatibility of your
specific LMI
®
metering pump. Contact your local LMI
®
distributor for further information.
Tubing Connections
Inlet and outlet tubing or pipe sizes must not be reduced. Make certain that all tubing is
SECURELY ATTACHED to fittings prior to start-up (see Section 2.3, Tubing Connections).
ALWAYS use LMI
®
supplied tubing with your pump, as the tubing is specifically designed for
use with the pump fittings. It is recommended that all tubing be shielded 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.
