Too long drying time
The actuator on a steam calorifier pulls via
a shaft a damper which opens/closes the
air inlet to the drum.
It is important that the actuator is firmly
fastened on the shaft, this is done by
locking the shaft extra tight to the actuator.
1. Unscrew one of the two hexagon head
screws in order to mark the positioning
on the shaft, the other screw must clamp
the shaft, while the marking is done.
Repeat this with screw no. 2.
2. Dismount actuator.
3. Drill a groove in the two marked spots.
This way the two screws are locked
tighter to the shaft when they are
tightened.
4. Mount the actuator and tighten the 2
hexagon head screws with 5Nm.
Note! It is a 1/8" key, not mm key
