Installation and Operation Instructions

6.2 Turning the Heating Cable On and Off
During the winter season, turn the cable on only when weather conditions are
favorable for ice formation. A cable should only be used when:
Snow or ice on the roof melts and the ambient temperature is between 15°F
and 35°F (-9°C to 2°C)
When the temperature rises above 35°F (2°C), the cable must be discon-
nected. The cable should be kept turned off until the weather conditions
suitable for melting/freezing water reappear.
6.3 Checking the Operation and Condition of the Heating Cable
During the winter season and during snow melt, make sure that melt water
can drain off the roof. The heating part of the cable and gutters should not be
clogged with ice and snow. Icicles should not form on the edge of the roof.
If icing persists, you will need to adjust the layout of the cable to better suit the
roof conditions.
To adjust the cable wiring diagram, first unplug it from the outlet.
Then find places where there is an excess of cable length. If the cable
length is insufficient, it can be obtained in those places where there was an
excess of cable length during initial installation, or the roof covering area
can be reduced where it is not so prone to icing.
Remove the cable by opening the clamps and spacers with pliers.
Reposition and feed more cable to the correct places as needed.
During operation, the ground fault protection device may trip if the cable is
damaged or as a result of water entering the outlet.
Before setting up a ground fault protection device, disconnect the plug from
the outlet and check the entire cable for damage. Remove and discard the cable
if it shows any signs of damage or deterioration, including cuts, charred areas,
cracks, discolored surfaces, or bare wires.
Do not use a damaged cable. If you do not see damage on the cable, reset the
grounding protection device. If the device trips again and there is no other ex-
planation for this, call a licensed electrician to check the cable and circuit.
If necessary, during the winter season disconnect the power cable to check for
the presence and removal of debris, such as leaves, pine needles, seeds, etc.
from the roof, gutters, and drains. About once a month during the winter season,
disconnect the power cable and perform the same checks as in the “Pre-Sea-
sonal Check” section.
Do these inspections in suitable weather conditions.
