1.1
UNPACKING
Remove tubing, injection check and foot valve (if included) from the pump carton. Notify delivery
carrier immediately if there are any signs of damage to the metering pump or parts.
1.2
LOCATION AND MOUNTING
a) When pumping solutions, make certain that all tubing is securely attached to the fittings. It is
recommended that tubing or pipe lines be shielded to prevent possible injury in case of rupture
or accidental damage. Always wear protective face shield and clothing when working on or near a
chemical metering pump.
b) LMI accessories used with the Series E pumps must be placed in an explosion proof enclosure or
located in an area where they will not be subjected to explosion hazard.
c) Be sure installation does not constitute a cross connection. Check local plumbing code.
A.
Locate the pump in an area that is convenient to both solution injection point and electrical supply.
LMI Series E7 metering pumps have corrosion resistant housings, but should not be subjected to
continuous high temperature (over 122° F or 50° C).
B.
Mount pump as shown below. Secure pump to shelf with 5/16” bolts through the four (4) holes in the
pump base. Shelf must be able to support 50 lbs minimum (23 kg).
C.
Figures 1 and 2 (below) show typical metering pump installation methods. Note location of injection
check valve which is most important. Refer to separate Liquid Handling Assembly Instructions
Section A regarding installation of injection check valve.

NOTE: Low temperature is 32 degrees F. If the fluid you are using has a lower freezing
temp, you may be able to pump at slightly lower temperatures.
