STEMCO Aeris SmartSense Upgrade Kit - Manual

Part# 571-1001
SmartSense Installation Page 1
Upgrading Aeris to SmartSense
DETAILS:
These instructions assume that the trailer already has a fully functional, basic Aeris Inflation System
installed.
OVERVIEW: The Aeris SmartSense system requires a dedicated ¼” airline run for each wheel end.
The airline connects from one of four labeled ports in the control box manifold to the designated
wheelend/axle entry point. Because of this requirement, each existing airline must be cut at a point
prior to the axle entry. Then the line may be spliced using a “one-to-one” DOT, brass, push-connect
fitting to a length of tubing that will reach the control box manifold port. The spliced airline must be
long enough to be routed back to the SmartSense control box and inserted into the corresponding
port (i.e. port labeled RR would be routed to the Right Rear wheelend).
1. Replace the existing control box with the SmartSense control box:
NOTE! Trailer air supply lines must be disconnected from the tractor prior to beginning this
upgrade.
a. Release pressure from the Aeris system by shutting off the control box inlet valve and
depressing the valve core on the regulator inside the control box (for about 5
seconds.) This will discharge all pressure in the Aeris airlines.
b. Remove the airline from the outlet fitting of the control box.
c. Turn on the air inlet valve to the control box to bleed down the trailer’s pressure tank
to the point where air flow has stopped.
d. Disconnect the airline from the entry side of the control box.
e. Remove the existing control box from the bracket by removing the three bolts/nuts.
f. Using new bolts, nuts & seal washers, attach the SmartSense control box to the
bracket. Note that the rubber-bonded seal washers are located inside the control
box, under the heads of the 5/16” bolts.
