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.
Precautions
Protective Clothing
ALWAYS
wear protective clothing, face shield, safety glasses
and gloves when working on or near your metering pump. Ad-
ditional 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, disas-
semble 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.)
Solution Compatibility
Determine if the materials of construction included in the liquid
handling portion of your pump are adequate for the solution
(chemical) to be pumped. LMI pumps are tested by NSF for
use on muriatic acid (up to 37% hydrochloric acid), and sodium
hypochlorite (up to 12.5% solution). Always refer to the solution
supplier and the
LMI Chemical Resistance Chart
for compat-
ibility of your specific LMI metering pump. Contact your local
LMI distributor for further information.
