Permit-Required
Conned Spaces
A conned space has limited openings for
entry or exit, is large enough for entering and
working, and is not designed for continuous
worker occupancy. Conned spaces include
underground reservoirs, ground storage tanks,
elevated tanks, silos, manholes, and pipelines.
Conned Space Tips
• Do not enter permit-required conned spaces
without being trained and without having a
permit to enter.
•Review, understand and follow employer’s
procedures before entering permit-required
conned spaces and know how and when
to exit.
•Before entry, identify any physical hazards.
•Before and during entry, test and monitor for
oxygen content, ammability, toxicity or
explosive hazards as necessary.
•Use fall protection, rescue, air monitoring,
ventilation, lighting and communication
equipment according to entry procedures.
•Maintain contact at all times with a trained
attendant either visually, via phone, or by
two-way radio. This monitoring system
enables the attendant and entry supervisor
to order you to evacuate and to alert
appropriately trained rescue personnel to
rescue entrants when needed.
Refer to 29 CFR 1910.146 for complete
regulations set by OSHA. Refer to your state's
regulations if your state established and operates
their own safety and health programs approved
by OSHA.
Protect Yourself
It is important that you comply with all relative
OSHA and local regulations while installing
and performing any maintenance to the mixer
circulation equipment.
Key OSHA Compliance Standards that must
be followed (and not limited to) are:
• 1910.146 Permit-required conned spaces
• 1910.147 Lockout/Tagout
• 1926.500 Fall Protection
Fall Protection Tips
•Identify all potential tripping and fall hazards
before work starts.
•Look for fall hazards such as unprotected
oor openings/edges, shafts, open hatches,
stairwells, and roof openings/edges.
•Inspect fall protection and rescue equipment
for defects before use.
•Select, wear, and use fall protection and
rescue equipment appropriate for the task.
•Secure and stabilize all ladders before
climbing.
• Never stand on the top rung/step of a ladder.
•Use handrails when you go up or down stairs.
•Practice good housekeeping. Keep cords,
welding leads and air hoses out of walkways
or adjacent work areas.
Refer to 29 CFR 1926.500 for complete
regulations set by OSHA. Refer to your state's
regulations if your state established and operates
their own safety and health programs approved by
OSHA.
Lockout Tagout
When the On/O switch is in the "ON" position,
the mixer may start up at any time if not already
operating. The mixer's On/O switch can be
locked out by placing a pad lock thru the door latch
of the controller after the switch has been turned
to the "OFF" position. The On/O switch is to be
used as the emergency stop.

pliers. (See Figure 1)
ANCHORING
For oating congurations additional anchoring systems may
be required, such as mooring or tethering, to keep the unit
in position within the pond or basin. In some applications,
suspending the unit from and structure above will work, just
be sure to use the dedicated lifting eyelets or eyebolts.

OPTIONAL FLOAT BALL ATTACHMENT
For attaching oat balls, locate the 1' oat chains and slide
through the oat pipe and add stop bolt at the top after
measuring out desired manifold submergence depth. The
oat ball will sit approximately 1/2 of the way submerged in
water. Be sure to tighten the stop bolt to prevent the chain
from sliding down through the pipe of the oat ball. (See

BASIC OPERATION
The AP Unit is designed to circulate water by bringing
water from below and sending it out across the top in a
thin layer causing a mixing eect.
The air diuser creates thousands of tiny bubbles
which produces a "Low Pressure Zone" that creates
an uplift suction ow through the intake draft tube, and
a slight mound at the water surface, producing gentle
ow radially outward from the AP Unit.
The water layers ow outward radially, in diverging
“stream lines” from the unit. As it does, vertical ow is
induced in between the water being drawn below and
the water above. At the level of the ow intake, water
is drawn from all corners of the pond. As this lower
layer of uid makes its way inward with converging
streamlines to the AP Unit, the water is forced
upward, toward the surface, providing gentle mixing,
de-stratication, and surface renewal.
The AP Unit requires a minimal amount of supplied air.
The air is supplied to the AP Unit with the optional air
feed hose that connects to air manifold.
It is acceptable to use the AP Unit on an as needed
or required basis. This will allow for reduced power
consumption and will benet in energy savings. This
will require the AP Unit to run on a timer or local
SCADA system.
Refer to air supply manufacturer for recommended
duty cycle and other operational recommendations and
constraints.

Figure 1: Typical Deployment (Not to scale) Air unit should be located away from water. Model May Vary.
Machine Deployment
1. Lay out hose from air unit location to edge of water. Air unit should be located a safe distance away from
waters edge.
2. Attach end of air hose to AP machine.
3. Attach anchor chain to unit at the desired distance from the surface with quick link. If anchor chain is longer
than needed, you do not need to cut it to length.
4. Attach air hose to air unit.
5. Deploy machine in desired spot by rst lowering in machine and then lower the machine slowly using the
anchor chain to the desired depth.
6. Plug in air unit and ensure that air is coming out of the machine. You should see ow coming out of the
machine after 15 seconds.
Adjusting Intake Depth
To adjust the intake depth you must adjust the anchor chain. The anchor chain is connected to the top of
the unit and the oat(s). To raise the intake depth, shorten the anchor chain and to lower the intake depth,
lengthen the anchor chain. To set intake depth, the anchor chain should be 30” less than desired intake
measurement.

UNIT CLEANING
The AP Unit is designed to provide continuous
operation with little to no maintenance. However,
in some locations signicant debris within the
pond may eventually get caught on the unit either
restricting the ow pattern at the manifold or
through the intake housing.
Debris may get caught in the air manifold, either
being too large to pass through or resistant to
sliding up the manifold housing. Often debris will
eventually work it's way loose and pass through
the unit or may be pulled through as other debris
passing through the unit will pull or slide snagged
debris through. If signicant debris is causing the
unit to clog, occasional maintenance and cleaning
may be required.
If required, debris should be carefully removed
from the manifold and be wiped clean from any
scum buildup on the outside of the pipes that
may contribute to preventing debris from passing
through the unit.
Figure 1: Debris Passing Through AP Unit.
WINTER CONDITION RECOMMENDATIONS
For locations where there may be public access or recreation such as ice shing, snowmobile trac,
or other activities on the water body during winter, Ixom strongly recommends removing the AP
Unit from the water body or, at minimum, turning the unit o in the late fall before freeze up. If
the unit isn't removed, but is at least turned o, the area around the unit would then freeze in solid as
the rest of the lake does, decreasing the chance of a serious accident near the machine.
If these recommendations are not followed, the AP Unit will cause thin ice several meters
around the vicinity, creating a very large hazardous area.
