NOTE: NOTE:
adequately sized and pressure rated to meet
the system's requirements.

ram down air pressure to 10 psi (0.06 MPa,
0.6 bar).
c. Touch ram jog icon and lower the ram until it
just contacts the product.
d. If the ram plate is inside the drum, inflate the
seal.
NOTE: NOTE: NOTE: To prevent damage to the seal, use

drum.

setting until the pump is primed. If necessary,
adjust the pump pressure.
f. Press the Ram Down icon.
g. Using the pressure settings for the various

pump does not prime properly with heavier
fluids. Decrease air pressure if material is
forced out around the inflatable seal.
