be plugged directly into an external electrical or electronic timer for timing applications (if the
rocker switches are turned “on). To repeat: it is important that the yellow cord must be
plugged in and powered up at least 10 seconds
before
the blue or black cords are plugged in
or powered up. The yellow cord can be left plugged in all the time without significant effect
on the lamp in the
Dual TripleBright II
; however, you can unplug it if you will not be using
the light for weeks at a time. The yellow power cord has no switch in the circuit; therefore to
disconnect filament power to the lamp the cord must be unplugged. Also only the blue and
black cords should be plugged into a switched wall outlet or external timer. The
Dual
TripleBright II
is operated from 115V 60 Hz or 50 Hz electrical power. The “on-off” rocker
switches for lamp (a) and lamp (b) are behind the baffle just above the power cords where
they enter the blue
TripleBright II
housing.
Inspect the
Dual TripleBright II
to make sure there is no shipping damage. Styrofoam
“peanuts” or bubble pack might be used to protect the
Dual TripleBright II
during shipping.
All that protective material (Styrofoam “peanuts” or bubble pack must be removed to clear the
fan opening and air exit before the light is operated. Make sure you
remove the red tape
that
holds the lamps in their sockets; the tape is only used to make sure the lamps do not come
loose during shipping.
B.
INSTALLING THE Dual TripleBright II IN YOUR DISPLAY
The
Dual TripleBright II
comes with four built in external tabs that accept small chains or
wires to hold the light to the top of your display. By adjusting the length of the chains or
wires you can tilt the light to almost any direction. There also are four tapped 8-32 nuts on the
back of the unit. The
Dual TripleBright II
weighs about 11 or 12 pounds depending on the
lamps used. If the
Dual TripleBright II
is installed vertically the fan should be positioned at
the bottom so it blows cooling air up.
C. CONNECTING THE YELLOW CORD TO PERMANENT 115VAC POWER
The cord with the yellow tape is called the yellow cord and it must be plugged in first to non-
switched constant 115V 50 Hz or 60 Hz power. The yellow cord powers the filament
transformer that supplies the filament voltage. The yellow cord should be plugged in
at least
10 seconds before
the
Dual TripleBright II
is turned “on”.
