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

liquid soap or an electronic leak device.
