Unpacking and Preparation
To remove the pump, separate the packing tape
and four staples from the sides of the box, then
pull apart the two box halves.
IMPORTANT! You will need to first remove
the internal packaging before the pump can
be used. A tag will be attached to the pump
alerting you of this.
To remove the internal packaging:
1. Remove the bottom bolt that secures the
screen with either a 5/16 in socket or an
adjustable wrench.
The loop is for
securing the pump
to the restraining
cable.

4. Now remove the pump body by simultaneously twisting the valve assembly
and pulling at the same time until the pump and the body easily separates.
5. Once separated, remove the upper-and-lower protective foam packaging.
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 check-valve, 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.
Maintenance
To clean the internal components
of the pump, remove the housing
as outlined in steps 1 – 4 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.
The control rod and float can
now be removed for cleaning.
The float springs must first be
removed from the float (see
illustration below, #29).
Remove the barbed fittings to
clean the exhaust and air-inlet
valves from any debris.
To reassemble the pump, follow the above steps in reverse order.
