Installing the Insulation Blanket
1. Fit the insulation blanket against the side of the Rain Collector cone, pushing it as far
inside the cone as it will go.
If fully inserted correctly, the blanket should extend all the way to the top of
the cone, leaving a space of approximately 5/16" (8 mm) at the bottom to
accommodate the base.
2. Re-attach the Rain Collector cone (with insulation blanket) to the base.
P
OWERING THE
Running the Cables
Run the heater cable from the Rain Collector to the location at which you plan
to plug in the wall transformer/power unit. To prevent fraying or cutting of
the cable, secure it so that it does not whip about in the wind. Use cable clips or
weather resistant cable ties to secure the cable underneath the eaves of your
house/building, or in a location similarly shielded from rain. Make sure the
cable is secure by placing clips or ties approximately every 3-5 feet (1-1.6 m).
Do not use metal staples or a staple gun. Metal staples, especially when
installed with a staple gun, have a tendency to cut the cables.
Note: If your cable run extends more than 50 feet (15 m), keep the heater cable and the Rain Collector
cable separated by at least a few inches, as discussed in "Choosing Cable for the Rain Collector
Heater" on page 3.
Attaching Cable to Power Unit
1. Remove the base of the power unit by removing the four screws in the base.
2. Loosen the screw heads on the terminal block.
You will eventually secure the heater cable wires underneath these screw
heads.
