Answer to Question 1

Some units have a critical charge and installing gauges can lose enough refrigerant to make the system undercharged.

Answer to Question 2

When the valve is back seated, the service port is closed and the center port is open to the line port. When the valve is front seated, the line port is closed and the center port is open to the service port.
