and pulling at the same time until the pump and the body easily separate.

To clean the internal components
of the pump, remove the housing
as outlined in steps 1 – 3 in Packing
and Unpacking, then remove the
cotter and clevis pins from the
bottom assembly before sliding
the “T” assembly from the center
discharge tube.
Note: This packaging is provided to protect both the float and control rod from
damage during shipping. DGSI recommends that you save this packaging as
well as the box for any future shipping requirements.
To reassemble the pump, follow the above steps in reverse order. When
installing the bottom plug, it is recommended that you stand the pump upside-
down on the discharge hose-barb, then tighten the two bolts to pull the O-ring
seals into place.
