2. Rotate crankarm on actuator 1/8 turn back to original position. Tighten nut and bold on crankarm. This will apply extra pressure to blade seals.

on the crankarm is in the correct location. If the blades are not completely closing the ball swivel can be adjusted SLIGHTLY. An over adjustment can cause damage to the blades.

Caution: Before operating the louver, make sure the location of the ball

swivel on the crankarm allows the proper travel length.

It maybe necessary to adjust the swivel on the crankarm after the initial adjustments are made. This can be done by sliding the swivel in or out on the crankarm.

cause the blade to open more.

Sliding the swivel in on the crankarm will

cause the blade to close more.
