Permit-Required
Conned Spaces
A conned space has limited openings for
entry or exit, is large enough for entering and
working, and is not designed for continuous
worker occupancy. Conned spaces include
underground reservoirs, ground storage tanks,
elevated tanks, silos, manholes, and pipelines.
Conned Space Tips
• Do not enter permit-required conned spaces
without being trained and without having a
permit to enter.
• Review, understand and follow employer’s
procedures before entering permit-required
conned 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

The SolarBee 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 tank. As this lower layer of uid makes its
way inward with converging streamlines to the
SolarBee, the water is forced upward, toward
the surface, providing gentle mixing and
de-stratication.
The SolarBee obtains all the energy it needs
from the sun. Its solar panels provide power
to the onboard battery which energizes the
drive system’s controls and motor. Excess
solar energy is stored during the day and
used during the night allowing the SolarBee
to operate during the night without being
connected to the grid.
During operation, a visible ow can be
observed coming off the distributor dish
and spreading outward. The impeller of the
SolarBee is designed to operate at full speed
when there is sufcient sunlight and battery
charge. The rpms may drop down some
during the later night and early morning when
the battery uses up its charge after a longer
period of overcast days. In severe sunlight
limited conditions, the machine may slow
down or stop temporarily to protect the battery
from damage.

STEP 1: Locate the Dish Assembly, Floats and Float Arms. (See Figure 1 & 2)
STEP 2: Attach the Floats to the Float Arms. (See Figure 3)
STEP 3: Attach the Float Arm Assembly to the Dish Assembly with provided bolts and nylock nuts.
(See Figure 4 & 5)
STEP 4: Repeat STEPS 1 through 3 for the other two oats.
IMPORTANT! The following pages give detailed instructions on how to assemble different 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 SB500PWc collapsible unit assembly to be installed without requiring oat disassembly.
For smaller hatches, the SB500PWc 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. The oat arm assembly is
pre-attached at the factory.

The SolarBee with technology includes new features
which enhance its performance through more e󰀩cient
and durable components, improved operation
monitoring capablilities, easy component access, and a
robust frame structure.
Solar / Electronics
Photovoltaic (PV) Modules -The PV modules are
often referred to as the solar panels. The SolarBee
uses 100% solar energy to provide day/night operation.
The PV modules collect solar power to operate the
machine with excess left over to charge an onboard
12-volt, deep cycle battery. The SolarBee has an
80-watt PV modules which individually connect to the
digital controller. A bird deterrent is located directly
above the PV modules to prevent bird fouling.
The PV module is generally placed on a low prole
structure which encloses the controller and battery.
The PV module is positioned so it faces the direction of
best sunlight.
The low prole solar panel stand o󰀨ers additional
protection by providing shading while also allowing
ventilation. Keeping the temperature down inside the
digital controller and the battery at a lower temperature
which extends the life of the battery and electronics.
Deep Cycle Battery - The deep cycle battery stores
excess power from the PV module during the day and
operates the machine using the stored power during
the night and extremely overcast days.

Digital Controller - The digital controller is located
inside the the low prole solar panel stand. The
digital controller operates and monitors the SolarBee.
The digital controller is programmed with application
specic run schedule, fallback rpm, and battery charge
settings. The SolarBee's Design and Application
Engineering groups are constantly reviewing the
program to optimize operation. The digital controller
can be updated with a new program (rmware) using
a SD (Secure Digital) Card, similar to that of a digital
camera's memory stick.
All solar energy collection and motor operation are
managed by the digital controller. This component
has two primary functions: (1) To direct and divide the
power being collected by the PV module(s) between
the brushless motor and battery. (2) To serve as the
main control center that operates the brushless motor.
There are 3 PV module connections located on the
front face of the digital controller. If the supplemental
AC power accessory was purchased, a connection will
be located on the right side face. The supplemental
power connection is used only in applications where
AC grid power is desired.
The left side face of the digital controller contains the
brushless motor connection, battery connection, and
On/O󰀨 switch. The On/O󰀨 switch activates power
to the motor. When the switch is turned to the O󰀨
position, the motor will not operate. The charging
function of the controller will continue to charge the
battery even when the switch is turned o󰀨.
SCADA outputs o󰀨ering machine operation parameters
reside within the digital controller. Please contact
SolarBee if you are interested in receiving these
parameters.

Motor Controller - The motor controller is located near
the motor just below the top plate of the SolarBee. The
motor controller is sealed in line with the electrical cord
that runs to the brushless motor.
The motor controller on the SolarBee receives power
and signals from the digital controller located inside the
low prole stand. These signals are used to operate
the brushless motor at the commanded speed. The
motor controller also sends feedback signals back up
to the digital controller.
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 SolarBee.
All electronic connections on the SolarBee equipment
should only be used for the inputs or outputs that
they are labeled and designed for. If any of the leads
going into the digital controller are disconnected, be
sure when re-connecting to place them in the proper
position, following the proper power up/power down
procedures.
Wiring - All electric wiring includes corrosion-resistant,
industrial cords with molded, weather and watertight
connectors. The connectors are indexed to prevent
improper wiring. A general electrical schematic can
be found in the Maintenance and Field Adjustment
section.

Brushless Motor / Impeller
Brushless Motor - The brushless motor is located
directly below the Top Deck. 4 bolts run down through
the Top Deck and into the housing of the brushless
motor fastening it onto the machine.
The brushless motor is built to be very durable. The
housing is constructed of casted aluminum. The
brushless motor runs very quietly and smoothly. It
does not require any maintenance. A drive shaft
extends through the bottom center of the housing.
Shaft Coupling - The shaft coupling connects the
brushless motor drive shaft to the impeller shaft. The
shaft coupling is located directly below the brushless
motor.
The rotating assembly (motor, shaft coupling, impeller
shaft, impeller) can be removed from the machine
without disconnecting the shaft coupling.
