Desiccant Filling and Replacement
The desiccant is the drying agent of the H300P chamber. The recommended desiccant is the Regular
Drierite 8 mesh desiccant.
The H300P comes preloaded with fresh desiccant. When the desiccant is fresh, it is blue. As the desiccant
gets used up, it turns red. When the desiccant is all red, it should be replaced.
Always use gloves and a mask when handling the desiccant. Avoid inhaling the desiccant dust as it may
irritate the lungs.
To replace the desiccant follow the procedure below.
•
Turn off and unplug the H300P chamber.
•
Remove the desiccant reservoir by gently spreading the holder clamps and pulling the reservoir
away from the back of the chamber. As you pull the two connector hoses will extend.
•
Pull until the hoses will not extend farther. Do not force the hoses to extend. See Figure 2 below.
