DISASSEMBLY
1. Remove the two self-tapping cover-locking screws.
2. Depress pump handle and remove cover.
3. Slide plastic front face up and out of slots on pump body, then
slide forward until it is clear of outlet pipe.
4. Depress pump handle slightly until sides are parallel with
pump body, then lightly push end of outlet pipe towards the right
side of the pump body until it is released from the pump handle.
5. Lay the pump handle over behind pump body.
6. Remove the outlet pipe assembly by lifting it straight upwards.
7. Turn D-4000 pump body upside down and catch internal parts
as they come out. Caution should be exercised so as not to
drop or loose any parts.
8. Should any internal parts remain in stainless steel tube, using
a straightened wire clothes hanger, insert through the bottom
end of pump tube and push out the other end.
NOTE. The bottom valve assembly may be pushing against a
large spring, piston body and an O’-Ring. Apply a steady
pressure. As the internal parts appear at the top of the pump
body remove them with your fingers.
9. To disassemble the valve assembly, begin with the bottom
valve assembly. Pull the bottom valve top away from the spring.
Do not loose the large stainless steel ball.
10. Pull apart the piston body from the piston presser with your
fingers, being careful not to loose the stainless steel ball or the
O-Ring
These pieces should also be cleaned with warm water and then
reassembled.
11. Any parts of the D-4000, which have not already been
cleaned, may be done at this time.
REASSEMBLY:
12. Holding D-4000 pump body vertical, drop the ball and
bottom valve top into the pump tube.
13. Drop the stainless steel spring into the pump tube with the
smaller end of the spring up.
14. Place the outlet pipe assembly with the piston body, small
stainless steel ball, O-Ring, and piston presser into the pump
tube. It may require some lubrication to work properly (e.g. lotion
soap).
15. Position the outlet pipe so that it is facing the right side of the
dispenser. Bring the pump handle over so that it is resting on the
top of the outlet pipe. With one hand on the outlet pipe, slightly
depress the outlet pipe as you turn it toward the front of the
dispenser thereby engaging the pump handle.
16. Slide the plastic front face over the end of the outlet pipe.
Push up on the bottom of the plastic front of the pump body.
Slide the plastic front face down and into place.
17. Holding the pump handle down, replace the aluminum cover.
18. Release the pump handle and insert the two self tapping
screws into the drilled holes in the bottom of the cover and pump
body.
19. The D-4000 is now ready to be reinstalled on the wall
bracket and put back into operation.
NOTE: As when new, it will take several pumping strokes to prim the unit before it starts to discharge soap.
