Air damper servomotor adjustment

First stage - CAM I
Cam I (Fig. 15) adjusts, using the micrometric screw, the position
of the 1st stage damper (factory calibration reference value 25°).
Second stage - CAM II and CAM III
Cam II (Fig. 15) adjusts the position of the 2nd stage damper (fac-
tory calibration reference value 50°, do not exceed 65°).
Cam III (Fig. 15) commands the opening of the 2nd stage valve
(factory calibration reference value 35°).
Cam II should always be anticipated by at least 15°.
CAM V
Cam V (Fig. 15) is positioned in the factory (factory calibration ref-
erence value 90°).
Do not tamper with this adjustment for any reason.
