After installation and linkage adjustment, operate the
motor through the thermostat or panel. Make sure that:
• The motor operates the damper or valve properly.
• The motor responds properly as input voltage is varied.
• The auxiliary switch, if used, operates at the desired
point of motor rotation.
Inspect the motor, linkage, and valve or damper to see that
all mechanical connections are correct and secure. In damper
installations, the pushrod should not extend more than a few
inches past the ball joints. Check to see that there is adequate
clearance for the linkage to move through its stroke without
binding or striking other objects. See System Instructions for
additional checkout procedures.
