8.4 Changing the desiccator
Danger! Hot surface!
Before replacing the desiccator, switch off the SPECORD
®
. Allow for a sufficient cool-
down time of the lamps. Touching the hot lamp surfaces housings may cause burns!

humidity. The desiccator is accessible, when the lamp compartment has been opened

Refer to Fig. 8-2, 5, p.33)
Especially in tropical countries, the adsorption capacity of the desiccator should be
checked regularly. The adsorption capacity of the desiccator is exhausted, if the color of
the indicator paper in the inspection window has changed from blue to pink-yellow.
For changing the desiccator, follow this procedure:
1. Open the flap of the lamp compartment by folding the lock frontward so it sticks out
vertically. Lift the flap from below by 1 to 2 mm and then pull it off to the left.
2. Using a flat tool, such as an appropriate coin, unscrew the desiccator from its
holder.
3. Remove the new desiccator from the packaging and screw it into the holder.
4. Finally, close the flap of the lamp compartment.
Used up desiccators can be reused after heating them up for five hours in a drying oven.
New desiccators are available from our Service Department (
