Routine Maintenance

of the STARLAB

While the STARLAB planetarium system is designed to stand up to repeated use, it

does occasionally need some routine maintenance to keep it operating in top form.

Here are basic maintenance procedures that should be done periodically.

Dome

The dome is made from a nylon/vinyl (no latex) composite fabric and is bonded to-

gether with specially-formulated adhesive. While the fabric is quite durable and does

not tear easily, it can get small punctures that allow light to shine through from outside

creating extra “stars” in the sky. These holes can be patched using peel-off adhesive

backed dome patches found in the accessory box. To patch the dome, inate it in a

brightly lit room and enter with a ashlight. Turn off all the lights inside the dome and

wait for any “stars” to shine through. Since the projector is not on, these “stars” are

holes. Peel and stick the patches onto the dome from the inside so they completely

cover the hole. If holes are too high to reach, simply turn off the fan and allow the

dome to deate until you can reach the holes. Do not use duct tape to patch holes.

If the dome gets dirty, it can be wiped clean with a sponge while inated with warm

soapy water. Never use cleaning uids or solvents!

Note

Never stand on a ladder or chair to patch holes. In the dark it’s easy to

become disoriented and fall.

Projector

Before cleaning the projector, make certain that it is unplugged from the electrical

outlet. Both the projector case and the clear plastic cylinder support platform can be

cleaned with glass cleaner and a soft cloth or paper towel. After repeated use, the

latitude adjustment bar may begin to sag. It can be easily tightened by using a

inch hex wrench and a  inch wrench over the nut that holds it to the metal support

bars attached to the side of the projector. Be careful not to overly tighten the nuts

because you won’t be able to adjust the latitude!

Projection Cylinders

Projection cylinders are made from lm and, while they are made to last, they need

to be handled with care. Any dents to the cylinder should be removed as soon as

possible. Dents can usually be popped out by applying light pressure on the outside

of the cylinder around the dent. Never put anything inside the cylinder because it can

scratch the images. Normal ngerprints on the outside of the cylinder will eventually

degrade the projections. It is not recommended that you try to clean the cylinders.

They should be packed up and sent back to Science First/STARLAB for periodic clean-

ing. In an emergency, cylinders can be cleaned with distilled water and a soft LINT

FREE cloth. NEVER use any type of soap, solvent or window cleaner on the cylinder!

When the outside of the cylinder is damp, it is extremely tacky and lint, dust and dirt

can easily stick to it, permanently damaging the cylinder. NEVER get water or any

other liquid inside the cylinder as it will destroy the images!
