7. Pull the Pressure Regulator assembly out from the panel.
8. It is recommended to use a small vice to hold the brass tee of the
Pressure Regulator in place, while removing the other fittings.
9. Using a wrench, remove the tubing elbow and the tubing T-fitting
from the Pressure Regulator.
10. Unscrew the Pressure Regulator from the brass tee.
11. Wrap PTFE tape around the threads on the brass tee, tubing
T-fitting, and tubing elbow.
12. Thread the new Pressure Regulator onto the brass tee.
13. Thread the tubing T-fitting into the opening on the new Pressure
Regulator labelled “IN”.
14. Thread the tubing elbow into the other opening in the Pressure
Regulator. Use the photo as reference for proper orientation.
Note: It any leaks are detected, ensure the fittings are properly
connected and sealed with the PTFE tape. Or, you may need
to cut a small amount of the tubing ends off to ensure a proper
seal in the fittings
18. Once successfully tested, place the panel in the Control Unit and
re-install the four hex screws. Re-install the batteries.
15. Place the new Pressure Regulator with connected fittings through
the panel, and use the panel mount collar to secure it in place.
Ensure proper orientation.
16. Push the tubing firmly back into the correct fittings. Use the photo
as reference for proper connections.
17. Before installing the panel back into the Control Unit, test it to
ensure proper connections have been made and to check for any
leaks. Turn the Pressure Regulator all the way up while testing.
