Each LevelVent Wellhead comes with a Support Hanger Bracket and a 2" Well Cap Assembly, which consists of an insert, well cap base and well cap.
The 2" Well Cap Assembly insert has two openings which can be used to install and support a LevelVent Wellhead. The second opening can be used to take manual water level measurements while the LevelVent logger is recording downwell. When the openings are not in use, two plugs are supplied with the assembly.

To accommodate 4" wells, a separate adaptor is available for use with the 2" well cap base.
An additional 0.89" (22.6 mm) access hole allows additional monitoring equipment in the well. Use a 3/8" Allen/hex key to remove the plug from the access hole.
The steps below show how to install the LevelVent using the Support Hanger Bracket and 2" Well Cap Assembly:
Connect the Vented Cable to the Wellhead and the LevelVent logger. See Section 1.5.1 for more details.
For diagnostic purposes, you may wish to install the end of the Vented Cable with the serial number, to the Wellhead connection at surface.
Slide the well cap base onto the well casing. Do not secure it at this point.
Place the Support Hanger Bracket in the well cap base so it seats on the shoulder in the base. Place the insert into the well cap base.
There are three holes in the top of the Support Hanger Bracket that can be used to secure it in the well cap base with screws.
Remove one of the red plugs from the insert. Lower the LevelVent Logger and Vented Cable through the opening and down the well until the Wellhead seats in the insert. Remove the other red plug from the insert and take a manual depth to water measurement for your records.
Lift the well cap base with Support Hanger Bracket and insert from the well casing. Wrap the Vented Cable around the Support Hanger Bracket and slide into the cutouts to secure the cable to the bracket.
The holes in the bracket can accommodate twist ties or zip ties to secure the cable to the bracket if desired.
Lower the well cap assembly back onto the well casing. Secure the well cap base to the well casing if desired. Install the well cap. Note, you may need to remove the dust cap from the LevelVent Wellhead before installing the well cap.
