OPERATION
Step 4
Step 5
Step 6
Move drum into position under ram
assembly, ensuring that the drum
guides on the bottom of the frame
stop the drum directly centered
under the plate.
Check to ensure the proper gasket set is
installed for the drum being unloaded.
NOTE: The larger gasket included in the
gasket set should be approx. 1⁄2” to 1”
larger than the drum diameter and the
smaller gasket should be the same size
as the drum diameter. In some drum types
such as conical drums or large diameter
pumps, all three gaskets sets should be
installed. The largest gasket should be
placed between the two smaller sizes. For
conical drums with narrow bottoms, the
small gasket should go on the bottom.
The gaskets are NOT designed to completely
seal against sides of drum. Under
normal operating conditions, there will be
some slight weeping of drum contents.
Remove the drum lid to expose product
being pumped and hook drum retainer
hooks over upper edge of the drum. If
a plastic drum liner is used, the liner
should be draped over the drum lip and
then held down with same clamp that
is used to hold the drum lid. Tighten
drum retainer hooks to secure the drum
in the down position during operation.
When adjusted and tightened properly,
the drum should not move. The hook
can be placed on a different chain link if
further adjustment is needed.
Step 7
To active or reset the DUS unit, press the
green reset button any time the E-stop has
been pushed or the air supply has been
interrupted. NOTE: It is not necessary to
reset (start) the unit before each use, only
after the air supply has been interrupted.
Note: the red E-stop button is a safety feature
that will stop the unit at any time in
operation. It is recommended you press the
E-stop any time the unit is left un-attended to
prevent accidental use of the DUS.
Step 8
When moving the ram in the down direction,
stand towards the right of the unit and grab
the ram plate support rod with your left
hand to guide the ram plate into position.
Step 9
To begin process of adjusting RAM
DOWN air supply, first set regulator
to 0 bar (0 psig). Then increase air
pressure until the ram plate comes
in contact with the surface of the
drum contents. Never exceed a
maximum of 1.7 bar (25 psig).
