Installing the Rain Collector Heater
4
Earlier versions of the rain collector did not come with built-in holes for the
rain collector heater. If your rain collector does not have built-in holes you
need to drill them yourself following the instructions below. Otherwise,
skip to step 5.
Marking screw holes
3. Using a drill with a 5/32” (4mm) or a 3/16” (4.8 mm) drill bit, drill holes in
the marked locations.
4. Using a drill bit with a large enough diameter to allow your power cable to
pass through, drill a cable hole in approximately the position shown below.
For the provided 50' (15 m) cable, use a 9/32'' (7.2
mm) or a 5/16'' (8 mm)
drill bit. The precise location of the power cable hole is not critical.
