beginning the installation.
✦
Medium Phillips-head and Slot-tip Screwdrivers
✦
Drill with 5/32” (4 mm) or 3/16” (4.8 mm), and 9/32” (7.2 mm) or 5/16” (8 mm)
Drill Bits

Choosing Cable for the Rain Collector Heater
The Rain Collector Heater comes with a 50-foot (15 m) length of 22 gauge, two
twisted-pair cable. When using this cable, the red and white wires are joined
and used as one wire and the two black wires are joined and used as one wire.
You may use 22 gauge, two-twisted pair wire in this manner for cable lengths
up to 120 feet (36 m). If you want to use single pair cable, use the following
table to determine the minimum wire size for the desired length of cable run.
If the heater cable is routed with any
signal cable
(i.e. any cable running from a
sensor, junction box or SIM), be aware that for cable runs over 50 feet (15 m)
the heater cable’s voltage may interfere with sensor voltages in the signal. To
prevent this interference, do at least one of the following:
✦
Use twisted pair for the heater cable or the signal cable.
✦
Use shielded cable for the heater cable or signal cable (shield must be grounded).
✦
Keep the heater cable and the signal cable separated by several inches over most
of the length of the cable run.
