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.

The GridBee is designed to circulate water by
bringing water from below and sending it out
across the top in a thin layer causing a mixing
effect. The laminar layer ows outward radially, in
diverging “stream lines” from the distribution dish.
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 GridBee, the water is forced upward, toward
the surface, providing gentle mixing,
de-stratication, and surface renewal.
The GF series GridBee requires a minimal amount
of AC grid-power. The grid provides power
to the onboard AC:DC power box and motor
controller that drive the brushless motor. The GF
Technology allows the GridBee to operate during
day and night while drawing minimal amount of
power from the grid.
During operation, a visible ow can be observed
coming off the distribution dish and spreading
outward. The motor and impeller is designed to
operate at the same full speed as the
solar-powered SolarBee models.

STEP 1: Locate the Dish Assembly and Float Arm Assembly. (See Figure 1 & 2)
STEP 2: Attach the Float Arm Assembly to the Dish Assembly with provided bolts and nylock nuts.
(See Figure 3 & 4)
STEP 3: Repeat STEPS 1 and 2 for the other two oats.
IMPORTANT! The following pages give detailed instructions on how to assemble dierent portions of the
machine; however, the order in which the components are assembled and entered into the reservoir may
need to be altered based on the hatch size and whether the reservoir will be full or empty. For instance, the
hose assembly to the base of the machine can be performed on the reservoir exterior prior to lowering the
equipment inside if the hatch has a clear opening of at least 24 inch diameter (60cm). A hatch this size or
larger will allow the collapsible unit assembly to be installed without oat disassembly required. For smaller
hatches, the collapsible unit assembly will need to be broken down into multiple components and the hose
assembly will need to be performed inside the reservoir. The following order of operations listed is based on a
wet installation and small hatch opening.

STEP 1: Locate one end of the hose section and place hose clamp over the end. Be sure that hose and
clamp are installed above the metal rib of the ange and then tighten hose clamp as tight as possible
to rmly secure hose. (See Figure 5)
STEP 2: Fasten Hose to bottom of machine by pushing hose up and all the way up above metal rib.
(See Figure 6)
STEP 3: On the other end of the hose place the other hose clamp over the end. Fasten hose to the intake
box past the metal rib of the ange and tighten hose clamp to rmly secure hose. (See Figure 7 & 8)

The GridBee utilizes high ecient brushless
motor technology which enhance its performance
through more ecient and durable components,
as well as easy component access, and a more
robust frame structure.
Electronics
Electrical Control Box - The electrical control
box is located on the exterior of the tank /
reservoir. The electrical control box converts
110VAC power to a clean 45VDC power source
which then operates the motor controller. The
control box also consists of a ground fault
interupter (GFI) switch to aid in protection of faulty
circuits or shorting of circuits. A durable 316SS
Cord Grip is used to handle all weather elements,
protecting the penetration of the electrical cable to
the motor controller on the inside of the tank.
Motor Controller - The motor controller is located
near the motor just below the top plate of the
Gridbee. The motor controller is sealed in line
with the electrical cord that runs to the brushless
motor.
The motor controller on the GridBee receives
power from the electronic control box located on
the exterior of the tank. This power is delivered
as 45VDC which is used to operate the brushless
motor at the commanded speed.
Due to the high frequency of communication
between the motor controller and brushless motor,
the two components need to be located close
to one another. This is the primary reason for
having the motor controller located directly on the
GridBee.
