PREPARING THE FIXTURE
Before inserting patterns or a TwinSpin™ in your fixture, it is important to align the lamp. Position it in the reflector so that the circle of light is as smooth and even as possible. When the field of light is truly flat, it will appear a tiny bit darker in the center (this is an optical illusion).

When the lamp is positioned too far into the reflector, the center of the field will look hot. When the lamp is positioned too far back out of the reflector, the center will be dull and shadowed and the outer rim will look bright and harsh. 'Hot spots' cause premature warping of the patterns and may damage delicate designs.

INSERTING PATTERNS IN THE TWINSPIN ™
With TwinSpin lying on a flat surface, center a pattern in the shallow well on the lip of the circular opening. Then secure with a retaining ring.

• Begin by pushing one end of the ring into the groove in the corner of the lip. Hold firmly in place with your finger, pressing the ring against the pattern.
• Holding the ring firmly, work the ring around until it is all in place .
• Finally, allow the hooked end to snap into place. To avoid pinching your finger, hold a small screwdriver straight against the wall of the lip near where the notched end will land. You may press the ring down gently with your finger to make sure it is tight all the way around. Turn TwinSpin™ over and repeat on other side.

TIP
When using older warped patterns, be sure they are bent away from each other in the TwinSpin™ so they can't catch on each other while rotating.

INSERTING TWINSPIN IN THE FIXTURE
First, be sure that the lamp is properly aligned. Then slide the TwinSpin™ straight down into the iris slot just in front of the pattern holder. Be sure it is seated straight and as far down as it will go. Secure the TwinSpin™ cord so it does not contact the fixture housing.

CONTROL USING LINE VOLTAGE - You can plug your TwinSpin transformer directly into any 120V AC line and the patterns will rotate at full speed.

USING A DIMMER - To easily start, stop, and adjust the rotation speed, plug your TwinSpin™ 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. Use the optional in-line speed control to adjust speed, if so equipped.

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™ (with the patterns mounted) in the fixture. Run the lamp at full for approximately two minutes. Do not rotate the TwinSpin™. 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™ 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 FROM THE FIXTURE
It is best to allow your fixture and patterns to cool naturally before removing the TwinSpin™ 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™ 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
To remove a pattern from the TwinSpin™, 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™ 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™ 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.
