| Locate your Underground Receiver on the highest
available ground where there is no abnormal water drainage, such as exists
near a downspout. A place near the back door will give quick, easy access
in all kinds of weather.
Dig or auger a hole 6" to 8" deeper than the unit and at
least 4" wider than the Shell diameter if the hole is dug. This makes
it easier to tamp the earth around the Shell. Fill the extra depth with
gravel to form a base for good drainage.
Set the Receiver in the hole with the Step pointing in the most
convenient position for opening the Lid.
Make a level, wooden form, staked into its permanent position, to
create a concrete slab around the Receiver(s).
Place the Shell inside the hole so that it will be 1" above the
top of poured concrete. Tamp the earth tightly against the Shell. Be sure
to keep the Shell round (check by placing the Insert-Can in the Shell - it
should slip in easily).
Pour the concrete in the form and trowel a gradual slope away from the
form to the top of the Shell receiver. This will drain the water away from
the receiver. It may be necessary to work the concrete away from the
hinge. BE SURE THE HINGE WORKS FREELY BEFORE THE CONCRETE SETS UP.
Multiple cans are easily placed in a single pad or patio. It is a good
practice to install the Slab higher than the ground level to keep water
out of the receiver. |
