The two compression connector nuts must be secure to seal the unit from water damage. If a fitting is not
secure, tighten it using your fingers.
To locate the two compression connector nuts, see
Figure 6 on page 9
.

Place the HRE-450 in the selected installation location, then mark the mounting screw hole locations on the
installation surface using the mounting screw guides.

Do one of the following:
•
If the installation location is wood, use a drill with a wood or metal drill bit to drill the mounting screw
holes into the wooden surface.
•
If the installation location is concrete, use a drill with a concrete drill bit that is slightly smaller than the
diameter of the anchor nuts to drill the mounting screw holes into the concrete surface. Insert the two
anchor nuts into the mounting holes and tap the anchor nuts into place with a hammer.
5
While holding the HRE-450 in place, place a washer over one of the mounting-screw holes. Then use a #2
screwdriver to screw one of the provided screws into the mounting hole.
6
Do the same with the other mounting screw.
The HRE-450 must always be mounted vertically with the stubs pointing down. This prevents
wind-driven rain and running water from entering the enclosure. Do not install horizontally.
