CHANGING CHEMICAL CYLINDERS
31
On all F-6000 and F-5000 cylinders, a level gauge located on top of each cylinder indicates the chemical
level. Cylinders should be disconnected when one of the gauges indicates 5% or 10% if using pipe system.
Always change both A-SIDE and B-SIDE cylinders at the same time. The chemical cylinders are filled such
that both should run empty at approximately the same time. Cylinders should not be disconnected until new
cylinders have been “conditioned” (brought to proper operating temperatures).
CYLINDER DISCONNECT/RECONNECT PROCEDURE:
1. Close nitrogen ball valves and disconnect nitrogen hoses from depleted A-SIDE and B-SIDE chemical
cylinders.
2. Close the chemical ball valves on depleted A-SIDE and B-SIDE cylinders. Marked as #2 or #3 on diagram.
3. Disconnect the Stratoflex assembly from the depleted chemical cylinders.
4. Clean Stratoflex assemblies with DK 817 (do not use acetone) and lubricate with petroleum jelly or
grease. It is important to keep the disconnected Strat assemblies clean and lubricated, especially on the
threaded areas.
5. Clean chemical fittings on depleted cylinders. Replace grease in fitting on A-SIDE depleted cylinder.
6. Reconnect Stratoflex assemblies to a full set of heated chemical cylinders.
REMEMBER: Always match color-coded Strat assembly with color-coded cylinders before
connecting. A-SIDE = Red, B-SIDE = Blue. New chemical cylinders should be
brought to operating temperatures before reconnecting.
NOTE: Reconnecting follows procedures for initial connecting.
7. Make sure that all ball valves on the chemical cylinders are in the OFF position.
8. Remove hexagon shaped sealing caps from the top of new cylinders. For A-SIDE cylinder, thoroughly
remove protective grease from Stratoflex coupling and place in A-SIDE cap before connecting. Apply
a thin film of petroleum jelly to the thread area before connecting the corresponding female or male
assembly.
REMEMBER: Always match color-coded Strat assembly with color-coded cylinders before
connecting. A-SIDE = Red, B-SIDE = Blue.
10. Make sure that the fittings on the Stratoflex assemblies are clean. Clean with DK 817 solvent (do not
use acetone).
11. Connect B-SIDE Strat assembly to B-SIDE (Polyol) chemical cylinder. Connect A-SIDE Strat assembly to
A-SIDE (Isocyanate) chemical cylinder. Make sure that the ball valves are held in place and do not turn
during connection.
12. Tighten Stratoflex fittings until fully engaged. Make sure that the ball valves are held in place and do not
turn during connection.
NOTE: When fully engaged, the Strat assembly will not rotate.
13. Prepare depleted cylinders for return to FSI. (See pages 33-35)
