Procedure for using a Supercap™ Container
to Superodorize an LP-Gas Tank

1. Determine that the tank should be superodorized due to:
· a new tank being put into service
· a used tank which has been open to air being put into service
· a complaint of insufficient odor from the LP-Gas in the tank
· new downstream lines being placed in service
· other reasons determined by customer

Note: AdSpec recommends that any superodorizing be done before LP-Gas vapor piping system is purged and leak checked.

2. Select an appropriate sized Supercap™ for the LP-Gas tank:
· 500 through 1000 gallons water capacity
· 250 through 380 gallons water capacity
· 120 through 180 gallons water capacity

Note: For tanks and cylinders not in the above size ranges, please call AdSpec technical support at 800-494-7732.

3. If the tank being put into service contains air, purge or vacuum per usual practice.

4. Remove the brass plugs from the Supercap™. Save the plugs and Supercap™ shipping box.

Notes: Store Supercap™ units in a cool, well-ventilated area.
Do not remove plugs until immediately before use.
Do not use a vise or wrench on the tube section.

5. Insert into each end of the Supercap™ an Acme fitting with ¾"Male NPT by (appropriate to LP-Gas tank and delivery hose fittings).

6. Connect either end of the Supercap™ to the LP-Gas delivery hose.

7. Connect the other end of the Supercap™ to the liquid fill port of the LP-Gas tank.

8. Fill the LP-Gas tank per usual practice. The filling process will automatically burst the containment disks at approximately 70 psi and push extra PercapTM 355 ethyl mercaptan into the tank.
Note: the maximum allowable working pressure of a Supercap™ unit is 250 PSI.

9. After filling is complete, disconnect the fill hose and Supercap™, remove acme fittings from the Supercap™ and replace brass plugs. Also replace any cap on the LP-Gas tank fill port.

10. Remove the "superodorized" sticker from the Supercap™, place it on the LP-Gas tank near to the fill port, and enter date and initials.

11. Put the empty Supercap™ back into the shipping package.

12. When all Supercaps™ in a shipping box are empty, re-close the package, call the number for pickup on the return shipping label, and send to AdSpec for recycling.
