Well Cap Installation Instructions (WELL-CAP-02)
For use with a HOBO® MicroRX Water Level Station (RX2103 or RX2104) or Water Level Sensor Module (RXMOD-W1)
23988-B MAN-WELL-CAP-02
Before you Begin
Follow these instructions before deploying the water level sensor with a station or in a well. If the
sensor has already been installed in a well, remove it before continuing.
Attaching the Well Cap to a Well
This cap can be installed on a standard 5 cm (2 inch) pipe, metal or PVC, without glue as shown
at right. It also fits on most threaded 5 cm (2 inch) pipes. If the cap is too loose once installed on
a threaded pipe, add a small piece of connector pipe that has both a threaded end and a smooth
end. Attach the threaded end of the connector pipe to the threaded end of the original pipe,
leaving the smooth end of the connector pipe at the top to attach the well cap. As an alternative
to a connector pipe, you can add duct tape around the threaded portion so that the cap is snug
when placed on the pipe.
Place the closed well cap on the end of the well. Use a hammer or mallet to tap the well cap firmly
in place. Attach a padlock to the latch if desired.
Installing the Water Level Sensor in the Well Cap
1. Using the half of the disk with posts, thread the water level
sensor cable under one post and over the other post as
shown below. The station and sensor are shown as reference
for proper cable routing around the posts. Adjust the
positioning of the cable as necessary to ensure there is
enough length to reach the mounted station outside the well
while deploying the sensor to the desired depth inside the
well.
2. Insert the posts (with the cable routed as shown) into the
receptacles in the other half, forming one disk when
connected.
3. Insert the two screws through the posts and use a Phillips-
head screwdriver to screw them into place.
