Level Sensor 8–4
Column Leak Test
1. Cover the column hole in the switch compartment with your thumb.
2. Submerge the side of the level sensor assembly that you are testing into a container
of water that is deep enough (at least 19 inches) to submerge it up to the top of the
column at the switch compartment.
3. Look for bubbles coming out of the column.
Level Sensor Reassembly
Ensure that the inside of the two level sensor halves and the seal rim are clean and dry before
reassembly.
Note: If you are using a cordless drill or screwdriver, use one of the lowest torque settings or
damage may occur.
