WARNINGS
1. Do not mount MicroCel with integral damper
actuator where acid fumes or other corrosive
vapors might contact and corrode metal parts.
2. Do not mount MicroCel with integral damper
actuator where there is escaping gas or other
explosive vapors. The electrical arcing in the
actuator could cause an explosion.

a. Open for cw-to-open damper.
b. Closed for ccw-to-open damper.
CAUTION
To prevent serious control problems, do not position
cw-to-open dampers that do not have a full-open
damper stop at a setting greater than full open.
Loosen two cover mounting screws on MicroCel and
remove cover.
If damper shaft is 3/8 in. (9 mm) round or square, insert
Shaft Adapter into actuator output hub (Fig. 7) across
from Allen setscrews.
