Welded Float Assembly Vacuum Test, Galvanic Coating and Delivery Instrucions Specifications Sheet
1. Install the 1/8 NPT plug (part and location #2) into the tank.
2. Install the plastic plug in the bottom (part and location #4).
3. Install the vacuum gauge valve assembly into the SAE port (part and location #3).
4. Thoroughly clean all dirt and debris from the o-ring groove and surrounding surfaces with isopropyl alcohol.
5. Thoroughly clean the o-ring (size 256 70 shore A durometer Buna-N o-ring) with isopropyl alcohol and apply o-ring grease Dow Corning 4 or similar.
6. Thoroughly clean the surface of the aluminum plate with isopropyl alcohol and remove all debris.
7. Install the o-ring and aluminum lid (parts and location #1).
8. Connect Firm Polyurethane Tubing (1/8" ID, 1/4" OD) to vacuum pump (supplied by vendor).
9. Ensure the quarter turn valve is open and begin pulling vacuum. The aluminum lid may need to be pressed down to establish a seal.
10. Allow the pump to pull a vacuum somewhere between 12 and 15 in-hg. Close the quarter turn valve and record the final gauge reading.
11. Allow the vessel to sit for 24 hours. If the vacuum gauge reading has fallen by more than 2 in-hg over the duration, it could indicate a leak somewhere or a problem with the weld. You may try tightening the npt plug more and trying again, or there may be a pinhole in a weld somewhere.
12. Once the vessel passes the vacuum test it can move on to spray galvanize paint.
13. Ensure that all holes the o--ring surfaces are properly masked before applying paint.
14. Use Crown Cold Galvanize Coating, 93% zinc rich, premium 7007 spray paint to fully coat the welded assembly.
15. Protect the upper flange o-ring surfaces with cardboard or foam for delivery.
