Packed with the Smartest Technologies
to ensure complete and effective air movement
throughout your facility
Variable Pitch Technology (VPT™)
Our innovative Variable Pitch Technology lets you adjust the blade pitch 0°~20° – up or
down – to blow air in a columnar flow or conically disperse it for a broader reach (we call it
Adjustable Air Movement). When multiple fans are arranged in an array, some may be
adjusted to blow air upwards while others blow downwards, creating a complete wave-like
movement of air within a facility (what we call Complete Facility Movement of air).
Rotatair™ Composite blades
Another innovative and advanced feature is our Rotatair blades, which we have designed
to ensure optimal performance and provide equal effectiveness in moving air up or down.
Molded from durable and lightweight composite material they are capable of higher
rotational speed (compared to other types of blades) with lower turbulence to work
efficiently in the wind of other blades.
MultiMode Smart Control
Our low voltage, simple but multi-functional Smart Controller provides five modes of
operation –
Manual Mode > The user controls the fan speed and blade pitch. EcoMode > The fan is
programmed to select the most energy efficient pitch for a given speed. DeStrat Mode >
The fan turns on and off automatically based on temperature differences between floor
and ceiling at user set speed, pitch, and direction (up/down). AutoMode > The fan selects
speed and pitch based on temperature differences, and turns on and off automatically.
The user merely sets direction (up/down). External Input Mode > The fans can also be
run by user specified external devices such as Thermostats and Timers.
Innovative Fan-sizes
Available in 15 ft, 12 ft, and 9 ft diameters, AirMotion HVLS Fans provide the air
movement of much larger fans (we calculate that our 15 ft fan can provide up to 33%
more CFM than older generation 24 ft HVLS fans, and save more energy). And the
innovative sizing allows them to be installed within most typically spaced sprinkler and
lighting setups, keeping local fire marshals and insurance underwriters happy while
avoiding counter-productive strobe lighting effects.
Energy Efficient Eco Technology
AirMotion HVLS Fans are engineered with energy efficiency as a fundamental design
imperative to ensure substantial energy savings, so you get increased comfort and
productivity while leaving a smaller carbon footprint.
Easy Installation
Low profile design, simple mounting, low voltage wall box control unit, and standard 120V
Single Phase make AirMotion HVLS Fans easy to install in most applications.

By using Variable Pitch Technology™ AirMotion HVLS Fans provide
you Adjustable Air Movement with one fan...
...and Complete Facility Movement of air with multiple fans
arranged in an array at your facility.
With three or more fans arranged in an array you get an all-encompassing air movement and mixing
throughout your facility by alternating air flow direction up and down – what we call Complete Facility
Movement of air. Typically, for cooling objectives, we recommend one fan for up to 10,000 sq ft or
more. For heat de-stratification and general air mixing objectives, we recommend one fan for up to
20,000 sq ft or more as desired.
Lower Pitch – Up
You can also get the columnar air-flow
upward with the same degree of
pitch set in reverse
Lower Pitch – Down
When set in Lower Pitch, the fan provides
you a columnar air-flow
Higher Pitch – Up
You can also get the conical air-flow upward
with the same degree of pitch set in reverse
Higher Pitch – Down
When set in Higher Pitch, the fan provides
you a more conical air-flow for broader reach,
better air mixing, and performance comparable
to much larger HVLS fans

OPERATING INSTRUCTIONS AND FUNCTIONS
04
In Manual Mode the speed and pitch are adjustable while the fan is operat-
ing, allowing the user to ‘dial in’ the optimal air velocity, direction, and speed
for the given facility conditions and air movement objectives. We call this
Adjustable Air Movement. (Please note, as the fan reaches approximately
¾’s maximum speed, the maximum pitch is limited to avoid overloading the
unit.)
In addition, the fan can be operated in EcoMode, where the fan adjusts the
pitch to what we have determined to be the most efficient angle for a given
speed.
We have a De-Strat Mode where the fans automatically turn on, and then off,
at specified temperature deltas between the fan at the ceiling and the wall
box control unit.
In AutoMode the fan comes on and off based on temperature differences,
and runs at various speeds depending on how large the temperature
difference is.
AirMotion HVLS Fans may also be connected to external inputs such as
thermostats and timers in External Mode.
For safety, our fans stop slowly upon shut down, include a timed delay to
prevent start-up while the blades are spinning if the power is interrupted,
include motor overloads, and have a field disconnect capability.
Our fans can also tie into fire safety suppression controls.

Wall Box Control Operation and Display Details
AirMotion AltAir HVLS fans are sophisticated in design and simple to operate.
The Wall Box is easy and intuitive to operate, and the display information useful.
The following provides more details on how one can utilize the many features and
capabilities of these fans.

First Time Powering Up (and after power has been interrupted)
The fan display shows a countdown timer of 45 seconds. The display shows
the time left and flashes ‘WAIT’ until the fan can be turned on and then
operated in any mode.
To Turn the Fan On and Operate
Press the power button once. The display will show ‘ON’, the previous Mode
used (see To Change Mode), the RPM and Pitch Angle up or down last set,
and begin to adjust to those settings by showing RPM and Pitch Angle
progress as the fan comes up to selected Speed and Pitch. The display will
also show the temperature difference between the fan mounted near the
ceiling and wall box control unit mounted near the floor.
To Adjust Speed (20 ~120 RPM for the 15’ Fan)
Just turn the Speed dial clockwise to increase
RPM and counter-clockwise to decrease RPM.
The display will show the RPM selected and then
shows Speed progress until the selected RPM is
reached. The RPM may be changed at any time
while the fan is operating in any Mode (see To
Change Mode)
To Adjust Pitch (0º~20º up or down)
At center the Pitch is essentially 0º. Turn the
Pitch dial to right of center (clockwise) for
increasing Pitch Angle from 0º~20º to blow the
air upwards. Turn the Pitch dial left of center
(counter-clockwise) to increase Pitch Angle from
0º~20º to blow the air downwards. The Pitch
Angle may be adjusted at any time while the fan
is operating in any Mode (note that when
operating in EcoMode and AutoMode the fan
selects the Pitch for a given Speed, but the
direction may be changed up or down by turning
the dial right or left of center, respectively).
Manual Mode
The user sets the fan Speed and blade Pitch. Changes to both Speed
and Pitch can be made while the fan is operating.
EcoMode
The user controls Speed and Pitch direction (up or down). The fan is
programmed to select the most energy efficient Pitch Angle for a given
Speed.
De-Strat Mode
The fan is programmed to turn on automatically when built-in tempera-
ture sensors detect a difference of 15°F between the fan unit and the
Wall Box Control Unit, and turn off when the temperature difference is
reduced.
AutoMode
The fan comes on and off based on temperature differences, and runs
at various speeds and pitch angles depending on how large the
temperature difference is. The user only selects Pitch direction (up or
down).
External Mode
There is a provision for connecting External Devices to the Wall Box
Control Unit as some users may want to use a Thermostat or Timer to
turn the fan on and off.
To Change Mode (MultiMode Control capability)
Modes are selected by pressing the MODE button while the fan is operating.
There are 5 operating modes for an AirMotion AltAir HVLS Fan –
To Turn the Fan Off
Press the power button once. ‘OFF’ will display and the fan will slowly stop
spinning (showing declining RPM on the display) and return blade pitch to 0º
(showing declining Pitch Angle on the display).
The display shows the fan is ‘ON’, in Manual Mode, at 97 RPM, 14° Pitch Angle down,
and the temperature at the fan is 8°F warmer than at the wall box.

Our 15 ft diameter fan is designed to provide larger fan performance, yet with
greater versatility, while fitting into tighter spaces where obstructions and
spacing above or around the fan may be challenging. Designed for easy and low
cost installation, they can be installed in most any structure, as long as the
blades are set a minimum of 10 ft above the floor. Ideal heights are generally 15
ft or more, and we are unaware of any height limitations.
Weighing about 230 pounds, they come standard with a single point mount, but
a 4-point mounting can also be used (contact AirMotion Sciences for this option),
both of which allow for greater flexibility and simplicity in mounting. Depending
on the direction of the pitch, there will be some lift associated with the operation
of the fans – reducing weight when blowing down, and adding some weight when
blowing upwards.
LOCATING THE FAN
The fan unit is approximately 2 ft in height, from blade level to top of cover, which
allows for mounting in tighter spaces. Though not a specific limitation as they
can operate with minimal clearance, ideally having 5 ft or more above the blades
allows for optimal air movement.
We recommend making sure there is at least 3 ft of clearance above and below
blade tips, and at least one foot of clearance to the sides of blade tips.
AirMotion AltAir HVLS Fans may be mounted up to 45 ft from walls and up to 90
ft from other AirMotion Fans. They must be mounted at least 15 ft from high
heat sources such as high heat machinery and processes as well as facility
heaters.
Please contact AirMotion Sciences or your local sales rep for assistance in
optimal fan location.

Attach the Universal Beam Clamp using the four 1/2” bolts with lock nuts
and washers. Depending on the thickness of the I beam, spacers may need
to be used to ensure the upper clamp is parallel to the Upper Mount with
U-Joint Block and Bolts.
Secure the 2” square tube (8” length is standard) to the Beam Clamp by
tightening the two 3/8” X 2” bolts with lock nuts and washers which are
already loosely preinstalled in the U-Joint Block at the factory.
Carefully bring the top of the fan unit up to the bottom of the tube, connect-
ing the lower mounting built into the fan to the tube using two of the 3/8”
bolts with lock nuts and washers through the two holes at the forward (hub)
end of the fan.
Before letting the fan hang , attach the 3/16” safety cable with clamps,
first around the upper beam, then through the holes built into the top of the
fan structure. Using the two clamps provided, clamp both ends of the safety
cable together tightly. Wire ties to hold the safety cable snug are recom-
mended for neatness and to keep any stray wire from interfering with the fan
operation.
To limit fan motion, help keep it level, and as an additional safety feature,
attach the four guy wires using the clamps provided to the holes at the top of
the fan unit and to adjoining roof structures. Use 2 clamps at each end.
Check the front to back and side to side hang of the fan for uniform
levelness, using the guy wires to help make the fan unit level.
After the blades have been installed and final leveling has been achieved,
tighten all the guy wire clamps securely and snip wire ends to ensure no
loose wires can interfere with the fan’s operation.
Clamps securing guy wires to roof structures may be secured when first
installed to limit guy wire installation steps after the blades are installed to
close proximity around the fan.
Make sure the U-Bolt side of each clamp is placed on the short turn-back
side and the saddles side, where nuts are tightened, is located on the long
side of the guy wire.
Optimal Guy Wire Angles from the base of the fan are 45º-60º.
SINGLE POINT MOUNTING INSTRUCTIONS
Please refer to the diagram on the last page for our single point mounting
apparatus. All materials, hardware, and safety features are provided with
your fan, including the following –
Equipment needed for installation (besides appropriately sized tools for hardware
listed above and a level) include a scissors lift, bucket lift, a forklift, or some
other means of raising the fan up for mounting (remember this is a 230 pound
unit) and for attaching blades. More than one person may be necessary to move
the fan, however packaging has been designed to facilitate moving the unit with
a forklift.
We recommend you keep the fan in the shipping container, removing top and
sides, until it has been attached to the single point mounting apparatus as the
shipping container base has been designed to provide a secure platform to raise
the fan up for mounting.
Determine a suitable I-beam, truss, or other roof support from which to hang the
fan. AirMotion’s Universal Beam Clamp fits beams up to 10 3/4” in width and up
to 5/8” thick. Cross bracing, additional purlins or other means of support may
need to be installed to ensure a strong and rigid structure from which to hang the
fan.
Please consult with AirMotion Sciences factory representatives for specific
installation issues and unique challenges.

locations so as not to interfere with the operation of the fan , the blades may
be connected (refer to Connecting the Rotatair™ Blades). Power should not be
turned on to the fan until the blades are connected and all mounting and
installation steps are complete.
Local electrical codes may require a separate power supply shut off. Consult
your electrical installer for your specific facility requirements.
Please Refer to Operating Instructions section for fan operation.
ELECTRICAL CONNECTION
Your AirMotion AltAir HVLS Fan has been designed for simple electrical installa-
tion. Until all connections are made and the fan is completely assembled, make
sure the power is off and the circuit breaker on the Fan Power Module is in the
‘OFF’ position.
Materials provided with your fan include –
In its standard configuration the fan comes set up for use with 120V single-
phase power. As such, a power cord with a 3 pronged 20 amp plug may be used
with any 120V single phase 20 amp outlet (contact AirMotion Sciences if your
electrician cannot provide this).
In all cases, power must be brought directly to the fan. Each fan is tailored to the
specific power source so that connection is made through the top of the Fan
Power Module by connecting the appropriate power line wires to the pigtails with
cap screws already set up. For example, in 120V Single Phase, Black is Line (hot
power), White is Neutral (neutral power), and Green is Safety Ground. For
208/240 three phase, there are three Black pigtails for Line 1, Line 2, and Line
3, plus Green for Ground. For 480V connections are made directly to screws on
contactor (customer provides disconnect as circuit breaker not included in this
power configuration).
The fan is supplied with 100 ft of low voltage 4-strand control wire to connect the
Fan Power Module to the Wall Box Controller. Longer lengths (user provided) may
be used. Once connected to the Fan Power Module, the control wire will need to
be run down and connected to the low voltage (12V) wall box control unit. Be
certain the low voltage wire is adequately wire-tied to roof and building supports
so as not to interfere with the operation of the fan.

One at a time, mount the blades (with leading edge facing counter-clockwise
when looking up at the fan) to the shaft on the hub. Using the ¼” x 1-3/4” bolts
with Nyloc nuts, insert the bolts upwards with nuts on the top side. Tighten the
Nyloc nuts securely.
Securely attach the loop of the free end of each of the Blade Safety Straps
(which are preinstalled on the hub at the factory) to the 1st blade bolt closest to
the hub using the 6 ¼” Fender Washers and the 6 remaining Nyloc nuts. The
Blade Safety Straps should move freely under the washers so as not to interfere
with the pitch angle of the fan blades.
It may be found to be easier to alternate opposite blade mounting to balance the
weight of the blades during the mounting process.
Once all blades are on, some adjustment may be necessary of the guy wires (or
Unistrut™ if 4 point mounting system is used) to ensure fully level hanging (refer
to related mounting instructions).
Double check to make sure that all connections are tight and that nothing will
interfere with the operation of the fan.
At this point the power may be turned on and the circuit breaker switched to the
‘ON’ position. Your fan is now ready to operate for years to come!
RECOMMENDED PERIODIC MAINTENANCE
Other than periodic cleaning of the blades and performing safety checks of
mounting and fasteners, which we recommend be performed on at least an
annual basis, AirMotion AltAir HVLS fans are virtually maintenance free. The
gearbox, motors, and bearings are lubed for life.
CONNECTING THE BLADES
Note – It is recommended that power and wall box connections be made prior to
installing fan blades, but make sure the circuit breaker provided on the fan unit
is in the ‘OFF’ position and do not turn power on until all fan and blade installa-
tion steps are complete.
AirMotion AltAir HVLS fans are configured to run in a counter-clockwise rotation.
Accordingly, the leading (thicker) edge of the blades needs to point in a counter-
clockwise direction looking up at the fan. As the blades are symmetrical so
that they can equally effectively move air up or down, there is no top or bottom to
the blades.
All materials, hardware, and safety features are provided with your fan to
install the blades, including –
