Keep hands and fingers away from the ram
plate, pump fluid inlet, and lip of the fluid
container when raising or lowering the ram
to reduce risk of serious injury from moving
parts.
NOTICE NOTICE NOTICE
To prevent pinching or damaging the seal
during tote insertion, only inflate the seal
when the top lip of the ram plate is at, or
below, the top edge of the tote.
To prevent the seal from restricting smooth
movement of the ram plate within the tote,
only inflate the seal until it makes contact
around the perimeter of the tote.

a. Connect pump outlet fittings and hose
(not supplied).
NOTE: NOTE: NOTE: Be sure all components are
adequately sized and pressure rated to
meet the system's requirements.
b. Using the ram position control switch,
lower the ram plate into the tote until it
contacts the product in the tote.
c. If the system is equipped with an
inflatable seal and the ram plate is
located far enough into the tote to
properly inflate the seal, inflate it now. If
the ram plate is not far enough into the
tote for seal inflation, wait until enough
product has been evacuated to lower the
level of the ram plate in the tote before
inflating.
d. Move the air motor control switch to the
run position. Observe that the pump
begins to operate. Adjust air motor air
pressure as needed.
e. Move the ram position control switch to
the down position. Observe that the ram
lowers as product is evacuated. Adjust
ram air pressure as needed.
f. If using an inflatable seal and it has not
yet been inflated and the ram plate has
lowered far enough into the tote, inflate
it now.
g. Using the pressure settings for the
various functions, fine-tune the
pressures as needed.
NOTE: NOTE: Increase air pressure to the ram if NOTE:
the pump does not prime properly with
heavier fluids. Decrease air pressure
if material is forced out around the
inflatable seal.
