EDUCTOR VALVE DISASSEMBLY AND
REASSEMBLY
All instructions in this section are keyed to Figure 3
and the accompanying parts list.
Eductor Valve Disassembly
Unscrew the hose assembly (5, Figure 1) and dis-
connect the valve assembly from the pump. Re-
move the pressure gauge (15) and disengage the
piping from the eductor valve.
Secure the valve in a vice and unscrew the venturi
(1) from the valve body (2). Remove the gasket (14)
and clean the mating surfaces.
Use a socket wrench to unscrew the eductor
nozzle (13) from the valve body.
To service the valve plug (3), remove the valve han-
dle (6) and index plate (11) by removing the hard-
ware (8, 9 and 10). Unscrew the valve cap (12) from
the valve body. Remove the gasket (5) and clean
the mating surfaces.
Remove the wave washer (4) and pull the valve
plug from the valve body. Remove the O-ring (7)
from the groove in the valve plug shaft.
Eductor Valve Reassembly
Clean the valve plug (3), valve cap (12) nozzle (13)
and valve body (2) with a cloth soaked in fresh
cleaning solvent.
Most cleaning solvents are toxic and
flammable. Use them only in a well ven-
tilated area free from excessive heat,
sparks, and flame. Read and follow all
precautions printed on solvent contain-
ers.
Inspect all eductor valve components and replace
them as required.
Apply a small amount of light oil to the O-ring (7)
and install it in the groove on the valve plug shaft.
Slide the valve plug into the valve body and install
the wave washer (4).
NOTE
Apply Never-Seez" or equivalent compound on all
eductor threads before reassembly.
Replace the cap gasket (5) and screw the cap into
the valve body until fully seated.
Position the index plate (11) on the plug shaft with
the words SHUT-OFF" at the indicator on the valve
body. Reassemble the handle (6) at the 9 o’clock
position and secure it with the attaching hardware
(8, 9 and 10).
Screw the valve nozzle (13) into the valve body until
fully seated.
Install the venturi gasket (14) and screw the venturi
into the valve body until fully seated.
Install the pressure gauge (15).
Check the operation of the valve handle for free
movement in all positions.
Reinstall the valve piping and secure it to the pump
assembly. See Figure 1 and reconnect the hose (5)
to the elbow (3).
HOSE AND REEL DISASSEMBLY AND
REASSEMBLY
Hose Disassembly
(Figure 5)
Remove the hose and reel assembly from the unit
base. See Figure 4, loosen the thumbscrew (5), re-
move the clamp (6) and unwind the hose assembly
from the reel. Reach through the hole in the side of
the reel disc (7) and use a wrench to unscrew the
hose assembly from the pipe assembly (19).
Inspect the nozzle end of the hose assembly. Dis-
assembly in the field is not recommended; howev-
er, if the nozzle or other parts require replacement,
individual parts are available.
To remove the nozzle (8), remove the screws (10)
and separate the guard (9) from the hose end.
