Installation
Step 2 - Mount the Optical Air Eliminator
Depending on the strainer being used, the optical air elimina-
tor may be fastened to the strainer/air eliminator in any of four
90° rotational increments. Select the most suitable orientation
for ease of final installation of wiring and vent piping.
Fasten the optical air eliminator to the strainer using the
four bolts and washers. Tighten the bolts to a torque of 27
lbf-ft (37 Nm).
These retrofit instructions will show a system using a
Hi-Cap strainer/air eliminator; however, the optical air
eliminator may also be installed on other LC strainer as-
semblies used for refined petroleum products.
Step 1 - Remove Old Air Eliminator and Baffel Cup
After the internal pressure has been relieved from the system
and the assembly drained of liquid, remove the four bolts
and washers used to fasten the old air eliminator to the top
of the strainer. Inspect the O-ring and replace if necessary.
Step 3 - Connect the Vent Piping/Tubing
This connection is ½” NPT. Remove the pipe thread protector
and then connect the piping/tubing to the vent port. This pip-
ing typically connects directly to an overflow tank on a truck.
Step 4 - Wire the Solenoid and Sensor to the Register
Wiring instructions begin on Page 9.
