Unbolt the four- m6 x 20mm screws from thevelocity stack base located to the center of the baseNow separate the base from the velocity stack.

The four m6 x m20 bolts have been removed fromthe top of the velocity stack,

Pull the velocity stack base with the filter that isattached to the velocity stack.

The velocity stack with filter is now out of thepower box body.

Loosen the clamp on the filter neck in order to sep-arate the filter from the velocity stack.

Once you have loosened the filter neck clamp, con-tinue to pull the filter from the velocity stack,

The rectangular pre-filter screen is now slipped outof the channel along the body of the power box.
