Can I use the E-Pro®s reverse button to open the container valve initially?
No. First, the E-Pro® valve adapter should be installed with the yoke and gasket as shown in the operating manual. Then, as per industry standards, the valve should be opened carefully by hand using the special Powell wrench per instructions in the operating manual. After a leak check has been run and passed, the reverse button on the E-Pro® actuator can then be used to jog the coupler into alignment with the opened valve stem, and the actuator can be secured on the adapter with the supplied hitch pin.
