way valves.
(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
(4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation, close the
low-pressure knob on the vacuum pump coupling.
Stop the vacuum pump.
(6) Open the 2-way valve by 1/4 turn and then close it
after 10 seconds. Check all the joints for leaks using
