Removing and Replacing the Desiccant Assembly
1. Orient the turret to the Stow position.
2. Pull and tag the main breaker to disable power and steering control to the turret.
3. Support the desiccant assembly with one hand.
4. Locate a bottom retention screw that secures the desiccant assembly to the turret.
5. Push the screw head in, twist counter-clockwise a 1/4 turn, and then back off until the spring ejects the
screw.
6. Unfasten the remaining retention screws.
7. Remove the desiccant assembly from the turret.
8. Remove the replacement desiccant assembly from its vacuum-sealed bag.
9. Inspect the flat ring seal and make sure the seal is properly seated in place and has not come loose. The flat
ring seals the air exchange pathway between the desiccant assembly and the turret.
10. Place the replacement desiccant assembly into position on the turret.
11. Push inward until the breather check valves engage and the desiccant assembly sits flush.
12. Fasten the retention screws.
13. Restore power to the turret.

Removing, Refilling and Reinstalling the Desiccant Assembly

Refilling the desiccant material involves removing a filler port. The filler port is a bayonet style that can be removed
by hand. Make sure the desiccant material used for refilling has been stored in a cool dry location. Removing and
replacing the desiccant assembly involves unfastening 4 retention screws. The desiccant assembly has captive
fasteners – held by a spring loaded retention pin rather than a threaded shaft. Like a bayonet style, the screw
requires a 1/4 turn with inward pressure to release. The turret includes a breather check-valve that seals airflow
when the desiccant assembly is removed.
