ALITA DIAPHRAGM CHANGE-OUT INSTRUCTIONS
1.
Remove plastic air filter cover. (See Figure 24).
2. Flip pump upside down and unscrew 6 screws on the corners and long side of the pump. Flip pump over and proceed to
lift upper housing. (See Figure 25).
3. Rotate and slide out of the detection pin knob on top of the pump core. This moves the detection pin out of way when you
are pulling the magnetic bar out of the pump. (See Figures 26 and 27).
4. Pick any side, unscrew the 4 corner screws that secure the diaphragm housing to the pump's core frame.
For AL-150/200,
ignore all the screws not at the 4 corners.
(See Figure 28).
5. (See pointing arrow in Figure 28) Unclamp and pull the rubber elbow away from -the discharge port of the diaphragm
housing. Carefully use a small flat bladed screw driver to unbond / uncouple the rubber tube from the discharge port then
pull it away. (See Figure 29).
6. Next pull the diaphragm housing away. (See Figure 30).
7. Unscrew the hex nut at the center of the diaphragm and proceed to pull the diaphragm from the magnetic bar. (See Figure
31).
8.
If it is difficult to pull the diaphragm from the magnetic bar, use the handle of the screw driver as a hammer and nail down
the protruded rod screw of the magnetic bar from the diaphragm plate. (See Figures 32 and 33).
9. Repeat #5 and #6 on this guide for the diaphragm module on the other side of pump. Then grab on the diaphragm frame
than slide and pull the magnetic bar from pump core. (See Figure 34).
