You
should
untwist
your
tower
wires
once
every
3-­‐4
months.
To
do
this
easily,
use
a
three
wire
style
extension
cord.
Simply
unplug
the
three
prong
connector
(yellow
connector
in
the
figure
above),
untwist
the
wire
and
plug
the
three
prong
connector
back
in.
Leave
about
3-­‐4
feet
of
coiled
wire
which
allows
for
wire
slack
in
case
the
wires
get
twisted
in
the
tower.
