Cleaning Impeller
1. Follow steps 1A through 1E under "Disassembly and
Assembly of Pump" on Page 8.
2. Remove diffuser and impeller from pump per instruc-
tions under "Removing Motor for Service and Replacing
Shaft Seal" on Page 9.
3. Clean impeller and reassemble impeller and diffuser per

Cleaning Shallow Well Jet
To remove debris from venturi or nozzle, proceed as follows:
1. Disassemble pump per instructions on Page 9.
2. Turn venturi counterclockwise and remove it. The noz-
zle is now exposed. Remove it using a 5/8" hex socket
wrench with extension. Turn counterclockwise. If
socket wrench is not available, insert an ice pick or sim-
ilar pointed tool carefully into the nozzle. This will dis-
lodge debris.
3. Flush out the debris by running water through the nozzle
in the same direction as the dislodging tool was inserted.
4. Reinstall nozzle and venturi. Do not overtighten!
5. Reassemble pump per instructions on Page 9.
How to Handle a Gaseous Well
In some areas well water contains gases which must be al-
lowed to escape before the water is used. This can be done
as shown in Figure 11.
A good way of delivering gas-free water is to suspend a pipe,
closed at the bottom and open at the top, surrounding the
suction pipe. Since the gases rise in the well casing, the
water sucked down through the pipe and into the suction
pipe is free of gas. This type of well must be vented to the
outside of any enclosure.
