Level-Eye®Installation
The Level-Eye® installation should be performed before the filling
process. Only install the Level-Eye® head & wand onto an empty tank.
1. IMPORTANT! Verify all the tank contents are removed and the tank
is at atmospheric pressure.
2. Verify the wand and sealing nut are the correct sizes for the
targeted tank model.
3. Verify that the O-ring Seal is in place on the sealing nut.
4. Remove the old float rod from the knuckle on top of the tank.
5. Remove the sealing nut from the Level-Eye wand, thread the nut
into the tank knuckle, and wrench-tighten the nut. (NOTE: DO NOT
over-tighten or damage may occur.)
6. Guide the wand through the sealing nut and wrench-tighten the
compression fitting. (NOTE: DO NOT over-tighten or damage may
occur.)
7. Remove the cover from the Level-Eye and insert the provided
battery. Confirm that the LCD display turns on. (NOTE: Because
the head is not yet connected to the wand, a “no symbol” will
appear on the right side of the LCD.)
8. Attach the cover onto the Level-Eye head. Hand-tighten firmly to
fully engage waterproof seal.
9. Ensure the O-ring is in place on top of the wand.
10. Li up the wingnut on the Level-Eye base to expose Brass
Connector Jack #1.
11. Push the Level-Eye head onto the wand firmly until both Brass
Connection Jacks #1 & #2 are fully engaged with each other. (NOTE:
There should be no gap or obstruction with the connection.)
12. Hand-tighten the wingnut. (NOTE: DO NOT wrench-tighten or
irreversible damage may occur that is not under warranty!)
13. Ensure the “no symbol” is no longer displayed on the LCD
screen. This confirms a proper electronic connection of the Level-
Eye head with the wand.
14. Proceed to low and high calibrations. (NOTE: Level-Eye will NOT
provide accurate readings until the entire low and high calibration
process is complete. See reverse side for instructions.)
BATTERY PERCENTAGE
Level-Eye® is able to calculate the amount of battery power remaining
and display it by percentages on the LCD screen at any time.
To check the battery level:
1. Single press and release the “L” button to view the
battery percentage remaining. NOTE: The display
will read “bxx%” to indicate the remaining battery
life (i.e. b54%).
2. If battery level is less than 10%, a symbol will appear.

Level-Eye will not read below 100% until the liquid level dips below the
calibration point. Monitor gauge regularly according to usage for any change.
LCD displays an “L” next
to a number Normal reading “L” means “Level” and the number indicates what percentage of liquid gas is
le in the tank.
“No Symbol” is

NOTE: DO NOT perform a calibration while the No Symbol is present!
Check the brass jack connectivity between the head and the wand:
1. Loosen the wing nut at base of head and remove from wand.
2. Check brass connection jacks on both parts for debris or damage.
3. If connection is clear, wait 30 seconds and re-attach the head to the wand.

Level-Eye®Calibration
Level-Eye®calibration is a two-step process of setting the liquid level range from an empty
(low) level to a full (high) level for your specific tank size and model.
IMPORTANT! Calibration must be performed DURING the filling process to calibrate correctly.
