Setup checklist
2.
Find a surface with a slope of less than 8%.
3.
Set up supports so the crossbars are 49 in (1.25 m) apart. Check that the supports are aligned
properly to prevent twisting of the box.
Check the supports for damage and loose connectors
before setting up the model.
4.
One of the supports has an opening for the reservoir – be sure to place this support at the box’s
downstream end with the opening for the reservoir facing downstream. Labels on the supports
display arrows that indicate correct placement and orientation. Use these arrows as a guide for
proper support setup and reservoir placement.
5.
Insert the standpipe in the drain assembly from the underside of the box so that the standpipe
extends at least 2 in (50 mm) inside the box.
6.
Place the box on the supports. Before adding any weight to the box, be sure that the support ribs
on the box’s underside rest directly on the supports, and that there are no gaps greater than 0.25 in
(6 mm) between the support crossbars and the box support ribs.
7.
Place the reservoir under the standpipe and place the pump in the reservoir, lying on its side. Check
the pump filter for fine debris.
8.
Fill the reservoir with 27 gal (102 L) of water using the graduations on the inside of the reservoir.
Do
not exceed 27 gal (102 L).
9.
Place the sediment trap on the aluminum struts in the reservoir. Be sure the sediment trap sits
directly beneath the standpipe.
10.
Connect the tubing and flow outlet. Attach the flow outlet to the box. Place the Energy Dissipater
Unit under the outlet. The innermost cylinder of the EDU must align with the mouth of the flow
outlet and the EDU’s Y-shaped opening should face downstream.
11.
Fill the box with modeling media.
12.
Fasten the brick power supply to the leg of the downstream support. Plug the model’s power cord
into the GFCI provided with the model and plug the GFCI into a wall outlet.
Never plug the model’s
power cord directly into a wall outlet.
13.
Attach the Electronic Flow Controller to the box.
14.
Connect the power supply to the flow controller. Connect the controller to the pump. Match the
color-coded connectors. Adjust the knob on the controller to desired flow rate.
15.
Begin experiments and demonstrations.
