A: While the motor is thermally protected and permanently lubricated, the bearings are not sealed.
A: We would advise you to not use the speed control switch.
A: We do not have sound ratings on this fan.
A: The unit cannot be adjusted to compensate for the pitch or slope of a roof as with a wind turbine. As I recall, the manufacturer provided information regarding how to mount the unit and the recommended maximum amount of angle or slope of the roof where it is to be installed, perhaps from the manufacturer's website. I opted for the optional rheostat control switch instead of the thermal switch & found that it works very well. The unit is very quiet when in operation.
A: Yes, it is. It can be mounted on a roof with a maximum pitch of 15/12.
A: Yes, that is the correct installation.
