Description
Model 84824 overfill warning device,
designed for double wall tanks, functions as
air supply shut-off to pump when tanks
reach near full capacity. In shut-off position,
air is diverted from pump to signal whistle to
alert full tank condition. Warning device
automatically resets when tank is emptied.
Periodical operational testing can be
performed by lifting test button about one
inch; this should shut-off air to pump and
sound signal whistle. Release button and
valve will reset itself.

Installation
1 Valve must be installed in direction that
will permit free rise and fall of float
assembly. Inspect tank interior for baffles
that can obstruct float action.
2 Back off set screw in threaded collar one
full turn; this will release collar and allow it
to rotate freely around valve body.
3 Insert valve assembly into bung opening at
top of tank. Arrow on top of valve must
point to tank area selected for float
operation.
4 Hold valve top in position while screwing
valve collar into tank. Collar is fitted to
accommodate spanner wrench for
tightening.
5 Recheck arrow to make sure valve is in
desired operating position before
tightening collar set screw. When set
screw is tightened, valve is lockedin
operating position.
6 Place filters, regulators, oilers and air
valves in front of air supply line going to in
port of valve. Never place accessories and
valves in air supply line from out port to
pump.
Maintenance
Overfill warning device is similar to fine air
tool in that effective life and performance
can be reduced by dirty air (air that has not
been filtered to remove moisture and rust
particles).
Installation of filter, regulator and oiler in
air supply line going to in port is
recommended to minimize failures in valve
and pump. Hydraulic oil or 10 WT motor oil
is recommended for use in lubricator.
Antifreeze can be substituted for oil
whenever combination of extreme cold and
wet air are present.
Overfill warning device should be tested
several times per year. Test can be
accomplished by lifting test button one inch;
this will cut off air to pump and sound signal
whistle. Release button and valve will reset.
