Answer to Question 1

Some operate around 1000 rpm while others may operate around 800 rpm. The fan blades are designed to move air at a certain speed. If the fan blade is spinning faster than it was designed for, it will not operate as efficiently. Increasing the rpm does not mean that you are going to increase the airflow. In most cases the current draw and the temperature of the condenser fan motor will increase causing the motor circuit to open on its thermal load. The worst case scenario is that the motor will be burned out. If this were to occur in a system where there are no compressor pressure switches the compressor could be damage beyond repair.

Answer to Question 2

Some service valve wrenches use a ratchet mechanism. They may have a lever for reversing the rotation of the wrench; they can have up to four fixed sizes of square openings. The handles on service valve wrenches can be flat or offset.
