Fix the belt tensioner center screw in position and turn the belt tensioner eccentric counterclockwise until the tensioner indicator passes the marked
position.
Then turn the eccentric back so that the indicator reaches the marked position in relation to actual temperature.
At the same time, ensure that the center screw remains fixed. At 20° C/68° F, the indicator should be centered in the window.
If the indicator is not in the right position, the adjustment must be repeated.
