Select a location for the meter.  The inside unit is designed to be mounted on the wall using two screws 8.5'' apart.  The unit needs to be mounted within five feet of a AC power outlet.  It is recommended that the unit not be mounted in high traffic areas, as passerbys or employees may be tempted to press the ADD or RESET buttons "Just to see what happens."  The RESET button has a protection switch and the ADD button is covered with a rubber boot to help protect against this from happening.
    Select a location for the outside unit.  Proper location should be at least three feet above and one foot away from any heated surface.  In addition the location should be at least three feet away from chimneys, vents, or hot air exhaust.  When placing the unit in the vicinity of a chimney, vent, or hot air exhaust, take into account the prevailing wind direction.  It is recommended, but not mandatory, to place the unit on the prevailing wind side of the building.
    Plan the routing of the cable.  The cable path should run from the outside unit to the meter as directly as possible.  Try to keep the length of cable exposed to the elements as short as possible.  The cable used is a common 3 ply 18 gauge cable.  The cable may be cut or spliced as long as the connections are clean and protected.
