Powering the Heater
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 power unit terminal block.
You will eventually secure the heater cable wires underneath these screw
heads.
3. Using wire strippers or a knife, strip 3/8” (10 mm) of insulation from the
heater cable wires.
4. Feed the cable through the hole
in the power unit..
5. Bend each bare wire into a U-
shape and secure under a screw
head on the terminal block, as
shown below.
It does not matter which wire
goes to each screw as long as
only one wire goes to each screw
