This
Flexible Conduit loop was designed for use in new construction.
The conduit is a non-metallic material providing full protection
for the loop contained within. |
Preparation for Asphalt |
|
A. Determine the proper location for the loop, keeping the “T” and lead-in wire closest to the control
box. |
|
|
|
B. Arrange the flex conduit loop into a rectangle or shape and dimensions required for the job. |
|
|
|
C. The loop may be installed in the sub base (Fig 10) or simply placed on the surface and covered with a light coating of sand or dirt. |
|
|
|
D. Protect lead-in wire by means of an additional length of 1/2” flexible or rigid conduit of a non-metallic material. This conduit containing the lead-in should also be covered as above, wherever the asphalt would make contact with the conduit. |
Preparation for Concrete |
|
A.
Follow steps A & B above. |
|
|
|
B.
Do not lay the loop directly on the
rebar or wire mesh.
Maintain a
minimum of 3” away from any metal. (See Figure 11) |
|
|
|
C. When installing over rebar or wire mesh, use non-metallic stakes to suspend the loop above any metal reinforcements. |
| Note: You may opt to wait until the cement is poured and then float the loop into the cement, again maintaining a minimum 3” clearance from any metal reinforcement. |
| A. Follow steps A & B above. |
| B. Excavate to approximately one inch below the loop installation level. |
| C. Back-fill the bottom one-inch with sand and pack firmly. |
| D. Install the loop and lead and cover with sand to within 3" of the top of the trench and pack firmly. |
| E. Back fill the remainder of the trench with gravel and pack down. |
