3.2 Probe Installation in Underground Tanks
1. Refer to Figure 3-2. Install a manhole of at least 18 inches (45.7
cm) diameter around an unused fitting in the top of the tank.
This manhole must be large enough to accommodate a
weatherproof junction box.
If this fitting is not in the center of the tank, additional measurements
are required for probe compensation.
2. When using 4-inch (10.2 cm) floats, install a 4-inch (10.2 cm)
diameter riser pipe in the fitting. This pipe must be 19 to 60
inches (48.3 to 152.4 cm) long, enough to allow the cable from
the probe to reach a weatherproof junction box. Adjust
accordingly for 2-inch (5.1 cm) floats.
3. Install a weatherproof junction box near the riser pipe. The box
must be large enough to accommodate ½-inch (12.7 mm)
conduit.
4. Install the ½-inch NPT bushing (supplied with each probe) in the
weatherproof junction box.
