Removing
1. Remove the heater.
2. Using a Phillips screwdriver, unscrew the three screws securing the micromotor-reducer to the heater body.
3. Prying with a slotted screwdriver, remove the micromotor-reducer from the damper axis.
Installation
We install the micromotor-reducer and the heater in the reverse order. At the same time, before connecting the micromotor-reducer to the damper axis, we turn the damper to the lower position and combine the protrusion of the gearbox shaft with the recess in the damper axis.
