Maintenance (Continued)
2. Disconnect air volume control (AVC)
tubing and turn AVC 180°
counterclockwise. Any water in AVC
will then drain back into tank (See
Figure 21).
CLEANING DEEP WELL EJECTOR
1. Disconnect power.
2. Disconnect piping and well seal or
well casing adapter. (If pitless

4. Unscrew and remove pipe adapter
(if used).
5. Unscrew and remove the venturi.
Remove nozzle with a socket
wrench, if possible.
6. Clean nozzle as explained under
Step 8, “Cleaning Shallow Well

7. Reverse steps 1 through 5 to
reassemble.
PUMP DISASSEMBLY
1. Disconnect power to motor.
2. Disconnect wires to pressure switch.
NOTE: Mark wires for correct
reassembly.
3. Remove pressure switch tube from
barbed fitting on pump body and
