1. Close the pressure builder input (V-7) and output (V-6) Valves.
2. Allow the unit to vaporize the liquid that is in the pressure builder and closed off lines. It may require an hour
or longer to vaporize all the residual liquid and vent the gas through the safeties.
3. After all the liquid is vaporized, there will still be pressure on the lines that will not be vented through the safety.
Slowly loosen a fitting on both blocked lines a ¼ turn at a time until the line is able to bleed off the remaining
pressure.
4. Loosen the fittings connecting the pressure builder to the tubing.
5. Next, remove PCV-1 and associated tubing from the vessel by loosening the female connector that attaches the
tubing to the safety nipple.
6. Remove the Pressure Builder from the support brackets and install the Super Pressure Builder.
7. Using the new fittings provided in the kit and the current PCV-1, assemble the components according to the
drawing supplied in the kit. Use Teflon tape or another suitable thread sealant when threading the fittings into
the connections.
8. Open the pressure builder input (V-7) and output (V-6) Valves.
