Close the(6) Drain Valve. <br /> 2. Connect the(11)Vacuum Pump to the(4) Push-in Fitting <br /> 3. Apply a 85%Vacuum gradually <br /> 4. Stop the(11)Vacuum Pump and close(2) Ball Valve <br /> 5. Open the(12) Ball Valve to restore the atmospheric pressure before the(2) Ball Valve. <br /> 6. Disconnect the(11)Vacuum Pump <br /> 7. Record Vacuum and Time. REFER to Previous tip about gases pressure variation Vs. <br /> Temperature changes, better interpret ate Vacuum Differences. <br /> 8. Record the Vacuum value after one hour.The test is successful if no variations are <br /> detected. <br /> ATTENTION: With The vacuum Test there is no cha>Ice to locate a possible <br />
