NOTE
The belt which is too tight or too loose may generate noise
and be harmful to the unit.
Regulating belt of rate of tension, inner fan
Refer to

, Fixed bolt of electric motor’s supporting slide
was loosened, following electric motor was drived, belt of rate
of tension will begin change.
Method of belt tensioning using belt tension indicator
Calculate the deflection in mm on a basis of 16mm per meter
of center distance .Center distance (m)×16=deflection (mm).
