USING A DIMMER - To easily start, stop, and adjust the rotation speed, plug your TwinSpin II into a
dimmer. Most types (even inexpensive household dimmers) will work, although speed range and
resolution may vary. Electronic dimmers slightly clip the top and/or bottom of the speed range, but
offer good resolution. The best results are produced by autotransformers.
TURN-ON and HANG-UPS
When the patterns in your TwinSpin are new, you must burn them in before rotating for the first
time. Do this by placing TwinSpin II (with the patterns mounted) in the fixture. Run the lamp at full
for approximately two minutes. Do not rotate the TwinSpin II. If you do not burn them in before
rotating, the patterns will most likely jam. If your patterns catch on each other, or if the retaining
ring is not properly secured and slips, the TwinSpin II may jam and stop turning. Turn off motor as
soon as possible to prevent freezing. Remove the unit to correct the problem, reassemble, then
resume operation.
REMOVING TWINSPIN II FROM THE FIXTURE
It is best to allow your fixture and patterns to cool naturally before removing the TwinSpin II from
the fixture. Pulling it out 'hot' will cause warping and possible tearing of the patterns due to the quick
temperature change. Lift the TwinSpin II straight out of the iris slot. Take care that the handle of the
pattern holder behind it doesn't press against the patterns and dent them.
REMOVING PATTERNS FROM THE TWINSPIN II
To remove a pattern from the TwinSpin II, use a small pocketknife blade or flathead screwdriver.
With the tool, pry the notched end of the retaining ring out of the groove, IN toward the center, and
UP. Pop the ring out of the groove, and remove ring and pattern with your fingers. Tip: hold ring
lightly with finger to prevent flyaway.

QUICK CHANGES
If you are under pressure and need to change hot patterns in your TwinSpin, be prepared with a hot
pad or gloves. The elements will be too hot to handle. It is helpful to have an extra set of rings
handy.
SPIN DESIGN
TwinSpin II provides four design options. You may rotate a single pattern, two of a kind, or two
different designs. The fourth option is to use one or two rotating patterns to animate a 'still' which is
placed in the pattern holder. Check out the Shadow Play Catalog for the hundreds of Great American
Patterns available.
CAUTION
TwinSpin II is not intended for continual use in conventional 1000W ellipsoidal spotlights. For
continuous operation applications we suggest the new cool beam units such as the ETC Source IV or
the Altman Shakespeare.
