INSTRUCTIONS FOR SETTING UP COMET FOLLOW SPOTLIGHT

Packaged in 2 boxes: one contains follow spot head, second box: the standpipe, base assembly with casters attached and yoke.

Assembling the Follow Spotlight

Screw pre-assembled threaded standpipe into hole at center of base. Attach yoke onto the threaded telescoping pipe. You are now ready to position the follow spot in the yoke. The Comet yoke has a spacer welded to the right arm. The handwheel when positioned in the yoke shall be on the same side. Tightening the wheel increases tension on up and down movement of the spotlight. Some prefer the wheel loosened for easier movement, adjust to your preference. Your follow spot is assembled and ready for use. When first igniting the lamp, you may see smoke. This is normal during burn-in. It will disappear after a few hours usage. If controls appear stiff, they will correct with use. The iris leaves, constructed of stainless steel, must be tempered. Igniting the lamp, closing the iris and letting it burn-in for 2 minutes will accomplish this. Reopen the iris fully to allow for cool down. Repeat this

procedure until iris stops smoking and leaves have turned a bluish/black color. Do not “burn-in” iris for more than 2 minutes each time, you could cause severe damage to iris leaves. Tempering should be completed after a few burn-ins. Lamping: Your Comet follow spot is supplied with a factory installed lamp. When replacement is necessary, use a cloth towel to install the new lamp. Apply slight pressure to slide lamp into position. Be sure to wipe lamp clean of any fingerprints, oil or dirt. A dirty lamp will blister and burn out prematurely. The lamp to use is the 360W FLE……Always keep a spare lamp with follow spot. The follow spot draws 4 amps. If an extension cord is needed, the standard household variety is acceptable. If you have any questions, the Altman dealer from whom you purchased this follow spot will assist you. Be sure to ask him for an Altman follow spot Brochure to learn of other models available.
