Allow the container to stabilize for 24 hours, then weigh it. Record the weight, time
and date.

Reweigh after the recommended 48 hours. The test if most effective if the
container is not moved during this period, and if conducted in an area where
ambient temperatures are consistent.
The following calculation will provide the actual Normal Evaporation Rate.
Daily NER = Weight Loss (Step 3-Step4)
x 24 hours
Elapsed Time (Hrs.)
Compare the results of your test to the “as manufactured” NER value in the SPECIFI-
CATIONS section of this manual. A container in service should maintain an NER value
of less than two times the new specification. Any test result greater than two times the
listed value is indicative of a failed, or failing, vacuum. If NER is found to be high,
contact Taylor-Wharton Customer Service at (334) 443-8680 for disposition.
HAND VALVE REPAIR
The ball valves used on the XL-160/XL-180 may be replaced by removing fittings
and unscrewing the valve body from the container plumbing. When installing a new
valve, it is important to close the valve, and observe the presence of a small hole in the
ball that is visible through only one of the threaded openings in the valve body. This
hole is a vent that allows the valve to prevent pressure buildup due to liquid trapped in
the ball chamber when the valve is closed. When installing a replacement valve,
always check to ensure the hole faces the container when the valve is closed.
