C. CHECKING OPERATION AND CONDITION
OF CABLE
• During the winter season and when snow or ice on roof is melting,
check to ensure a complete path is available for melt water
on the roof to get to the ground. There should be no ice buildup
above the cables, and gutters should not be clogged with ice. Icicles
should not form at the roof edge.
If icing problems persist, the cable pattern may need to be adjusted to
better suit melt/freeze conditions of your roof. Observe these condi-
tions and adjust cable pattern (see Planning Your Cable Arrangement
pages 8 – 11) when conditions are suitable (see When to Install Cable
on page 5).
To adjust your cable pattern, first unplug the cable. Then, identify areas
where there is extra cable. This may include excess cable you
during the original installation or you may be able to reduce the cabl e
in an area that is not as susceptible to ice dams. Remove the cable by
opening the clips and spacers with pliers, as needed, to rearrange and
supply more cable to the needed areas.
• During operation, the ground fault protection device may trip if
the cable is damaged or as a result of "nuisance tripping". One way in
which nuisance tripping can occur is if parts of the electrical circuitbe-
come wet. This can happen if driving rain or blowing snow enter the
electrical receptacle. Use of a weatherproof in-use receptacle may
help eliminate this (see page 7).
Before resetting the ground fault protection device and when weather
and roof ice conditions allow, unplug and inspect the entire cable for
damage. Remove and dispose of the cable if it shows any evidence of
damage or deterioration, including cuts, brittleness, charring, cracking,
discolored surfaces, or bare wires. Do not use a damaged cable. If
you cannot see damage on the cable, reset the ground fault protec-
tion device. If the device trips again and there is no other explanation
for it, call a licensed electrician to check the cable and the circuit. A
licensed electrician can determine if the cable is damaged or if there
is some other problem with your electrical system.
• As needed during winter season, unplug the cable and check for
and remove all combustible debris from roof, gutters and down
spouts, such as leaves, pine needles, seeds and windblown trash.
• About once a month during winter season, unplug the cable and
perform the same checks as outlined in the Pre-Season Check section
on page 16. Do these checks when weather and roof ice conditions
allow.

D. RESETTING CIRCUIT BREAKER/REPLACING
BLOWN FUSE
At any time during operation, if the circuit breaker trips or the
fuse blows, stop using the cable. Unplug and inspect the entire cable
for damage when conditions allow. Remove and dispose of the cable if it
shows any evidence of damage or deterioration, including cuts, brittleness,
charring, cracking, discolored surfaces, or bare wires. Do not use a damaged
cable. Even if you cannot see damage on the cable, assume it is damaged if
you cannot find another cause for the tripped breaker or blown fuse.
E. OFF-SEASON INSTRUCTIONS
The deicing cable may remain on the roof year-round. However, to avoid
overheating the cable and increasing the risk of fire or electric shock, do
not operate the cable when outdoor temperatures begin to remain above
had
50°F (10°C) (i.e., at the end of the winter season). To avoid accidentally
turning the cable on, unplug it.
VIII. REMOVING THE CABLE
The deicing cable must be removed prior to replacing roof shingles or
starting roof repair. Other roof alterations, such as additions of antennae,
flag poles, etc. in the area of the cable may require removal of the cable.
Cable may also require removal for adjustment.
To remove cable, wait for weather conditions to allow. Then, unplug the
cable. Open the clips with pliers and remove the cable. Take care when
removing cable from a downspout to avoid snagging or cutting the cable
on sharp edges.
Inspect the entire cable before replacing it on the roof. If cable is in good
condition (no evidence of cuts, brittleness, charring, cracking, discolored
surfaces, bare wires, or other damage), it may be replaced on the roof,
according to the instructions.
If a replacement deicing kit is purchased, use only the new clips provided
with it. Do not reuse the clips from the previous kit. The new cable may
not be designed for use with the old clips. If the old clips are used, the
cable may be inadequately secured or may be damaged.
Note that other models of deicing cable may have different methods of
removal. Follow the instructions provided with those cables.
