Internal foam packaging
3. Now remove the pump body by simultaneously twisting the valve assembly
and pulling at the same time until the pump and the body easily separate.
4. Once separated, remove the upper-and-lower protective foam packaging.
To reassemble the pump, follow the above steps in reverse order.
The control rod and
float can now be
removed for
cleaning. Remove
the barbed fittings to
clean the exhaust
and air-inlet valves
from any debris.
Additional drawings and parts lists can be found at
www.DGSI.info
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.
