2103 Modem Module Section 6 Maintenance

6.3 Desiccant

The 2103 Modem uses desiccant to protect the internal components from moisture damage. The cartridge is filled with indicating silica gel, which is blue or yellow when dry. As the desiccant becomes saturated, the color changes from blue to pink, or from yellow to green. Replace the desiccant before the entire length of the cartridge turns pink or green.

6.3.1 Replacing the	The desiccant is contained in a cartridge located on the left side
Desiccant	of the 2103 Modem. To remove the cartridge, unscrew the collar
	and slide the cartridge out of the 2103 Modem. The clear tube
	reveals the silica gel desiccant inside.
Collar	To replace the silica gel desiccant:

	1.	Hold the cartridge upright with the collar at the top.
	2.	As shown in the margin, push the collar off the cartridge.
	3.	Empty the saturated silica gel beads or granules.
	4.	Fill the tube with new (Isco P/N 099-0011-03) or reacti-
		vated (see section 3.3.2) silica gel desiccant.
	5.	Press the collar onto the tube.
	6.	Slide the cartridge into the 2103 Modem. Tighten the collar
		to seal the cartridge in place.
Cartridge
6.3.2 Reactivating the	Silica gel beads and granules of desiccant can be reactivated.
Desiccant		CAUTION
		CAUTION
	Desiccant may produce irritating fumes when heated. Observe
	the following precautions:
	•	Use a vented oven in a well ventilated room.
	•	Do not remain in the room while the regeneration is taking
		place.
	•	Use the recommended temperature. Avoid heating the
		desiccant at higher than recommended temperatures.

There is the potential of irritating fumes coming from the desiccant during reactivation. Because of this, we urge you to use caution, and to heat the desiccant in a well ventilated room. Material Safety Data Sheets are in the back of this manual.

The desiccant’s ability to remove moisture may lessen with each saturation/reactivation cycle, resulting in a need for more frequent service. After several cycles, the desiccant may no longer be effective as it saturates too quickly. At this point, replace the desiccant.
