Emptying 1-Ton Container Through Plug
Opening
When neither angle valve in a 1-ton container can be
used to withdraw the contents of the container, the
venting assembly of the line filling adapter can be
connected to one of the plugholes in the 1-ton container
and the contents can be withdrawn through the venting
assembly.
a. Roll the 1-ton container until one of the plugs in
the front container head is uppermost.
b. Disconnect the angle valve adapter from the
venting assembly of the line filling adapter and close
both globe valves on the venting assembly.
c. Unscrew the uppermost plug from the plughole
(a above). Keep this plug nearby so that it can be
replaced after the 1-ton container is empty.
