About the Airius Designer Series Series
The Designer Series unit is an energy-ecient air
turbine, designed to connuously move a column
of air to the oor for destracaon and air
circulaon purposes. A typical system installaon
includes a series of units mounted just below
the ceiling, evenly spaced throughout a facility,
working in concert to improve comfort and
reduce HVAC energy consumpon up to 35% or
more*. Airius fans are available in several sizes to
accommodate a wide range of ceiling heights.
* THE PERFORMANCE AND RESULTS OF THE
DESIGNER SERIES SYSTEM ARE SUBJECT TO
MANY VARIABLES SUCH AS, BUT NOT LIMITED
TO, AIRFLOW OBSTRUCTIONS, THE INTERIOR
ENVIRONMENT, EXTERIOR ENVIRONMENT,
CONDITION OF BUILDING STRUCTURE, HVAC
SYSTEM PERFORMANCE AND/OR ELECTRICAL
SERVICE AND THUS, ACTUAL RESULTS MAY
VARY.
What’s In the Box
Each unit will arrive in its own box, fully
assembled. NOTE: 120VAC versions come with
a three-prong plug, and other voltages have no
plug supplied. You will need to have a qualied
electrician either wire the desired plug on to the
power cord or hard wire directly to the power
circuit. We recommend using a plug for easy
removal during maintenance.

Safety Precauons - Read &
Save
Warning! - To prevent re, electrical shock or
injury, please observe the following:
Electrical work must be performed by a qualied
person(s) in accordance with all naonal and local
codes/standards.

white-neutral/green-yellow-earth.
Warning! To prevent electrical shock and/or
injury, unplug/disconnect unit from power source
before you move unit, service unit or remove any
part of housing.
Warning! To reduce the risk of re or electrical
shock, do not use models 10, 15 and 25 equipped
with shaded pole motors or models 45, 60
and 100 with permanent split capacitor (PSC)
motors with any unapproved solid-state speed
control device. Models 45, 60, 100 and 125 with
electrically commutated motors (labeled as EC
or EL) are capable of variable speeds with the
proper controls. Contact Airius for addional
informaon regarding variable speed controls and
opons.
Do not carry the Designer Series unit by the cord.
Do not use the cord as a handle. Do not use the
cord to aach or hang the product. Be sure to
grasp the plug, not the cord, when disconnecng
this unit from an electrical outlet.
Do not use this product if it has a damaged
cord, faulty plug or any broken housing or motor
component. If the supply cord, plug, motor
or housing is damaged, it must be serviced or
replaced by Airius, its service agents or similarly
qualied persons to avoid a hazard.
To prevent damage, which may result in re or
shock hazard, do not expose this product to rain
or direct moisture. Do not immerse product
into water or allow water to drip into the motor
housing. Do not install outdoors or in an area
open to the weather. Shut o power to a wet
motor at source before servicing.
Spinning blades may inict eye or other physical
injury. Always replace a damaged blade.
Disconnect unit from power source rst. Contact
Airius for replacement blades. Plasc blades are
rated 5VA, the highest re-resistant rang for
plascs, and they will not maintain a ame.
Cauon! Some Designer Series products have
an unguarded impeller/fan blade. Do not use
in locaons readily accessible to people or
animals. Blades may inict injury when moving or
staonary.
To reduce the risk of injury to persons, install
product so that boom of moving fan blade or
the lowest moving part is at least 8.2 . (2.5 m)
above the oor or grade level.
The motor is thermally protected; overheang
will cause the motor to stop operang. The
motor may restart once normal operang
temperatures are achieved. If motor fails to
restart, disconnect motor from electric source
and contact Airius. Do not disable this safety
device or override this safety feature; doing so
will void the warranty.
Do not use any PVC product (electrical tape) with
the fans. If installing a fan in an environment with
cung oils in the air (producon machine shop)
contact the factory for assistance at 303-772-
2633.
Do not posion product near furnaces, replaces,
stoves or other high temperature heat sources.
Do not posion Designer Series unit such
that the downward air column created by the
Designer Series will be directly bisected by
another source of air ow, such as from another
fan or from an open supply register. Do not
posion the unit close to other objects that will
interfere with fan operaon. Do not allow fan
blades to come into contact with objects that can
lock or inhibit the rotor operaon.
Service and installaon: No lubricaon is
required. Bearings are sealed. Bail adjustment
can be made with a T-30 Torx driver/wrench, or a
5/32” Hex wrench may be used. Other tools for
service: T-20 Torx (7/64” Hex) & T-25 Torx (1/8”
Hex) and a #2 Phillips screwdriver.

Safety Precauons Connued
The Designer Series unit is designed to be used
with only the electrical voltage idened on the
label located in the nozzle and on the boom of
the motor. Connecng to any other voltage could
damage the motor and create an electrical hazard
and will void warranty. If you have a queson,
please contact the factory.
Assembling Suspended Ceiling units: See
addional instrucons for kit included with this
pamphlet or located in box containing kit.
Important: Install with hanging device or fastener
rated for a minimum of 5x the weight of the unit.
Never use zip es to hang the fan. Use care when
posioning the unit. To maximize performance,
make sure the airow is unobstructed into the
top of the unit and the downward airow is
unobstructed and allowed to reach the oor.
Cleaning: Unplug unit from power source rst to
prevent electrical shock and to avoid injuries from
spinning blades. Cauon: Staonary blades can
cause injury! You may clean the plasc housing
with a warm cloth, using mild detergent only. Do
not use petroleum products, thinners, solvents,
ammonia, alcohols or other chemicals to clean

Pre-Installaon
Electrical
ELECTRICAL WORK MUST BE PERFORMED
BY A QUALIFIED PERSON(S) IN ACCORDANCE
WITH ALL NATIONAL AND LOCAL CODES/
STANDARDS.
Airius recommends installing a dedicated circuit
only to be used with the Designer Series units.
DO NOT wire the units into the lighng circuit,
as the system will cycle on and o with the lights,
greatly reducing the system’s eecveness.
Outlets are available in many conguraons,
check with the local electrical contractor to
determine the preferred type for the facility.
Outlets should generally be mounted vercally
unless a “twist/locking” type is being used.
To conrm electrical connuity, if possible, plug
the Designer Series system into an energized
outlet at oor level, similar to the outlet installed
in the ceiling, before permanently mounng the
Designer Series in the ceiling. Only energize
the fan aer hands/ngers or loose clothing are
removed from/around the fan intake.
CAUTION − Make sure the fan voltage matches
the intended power supply before installing.
Connecng the fan to the wrong voltage will void
warranty.
Mechanical
A ladder, scissor li or other suitable means of
reaching the installaon point will be required.
The Designer Series system is designed to hang
vercally 12-to-18 inches below the ceiling of
the facility with the discharge poinng to the
oor for maximum thermal equalizaon. NOTE:
The bail may be angled, as it is ratcheted for
special situaons where a vercal air column is
undesirable and an angled column would be more
eecve.
Make sure the air column will have an unimpeded
path from the discharge to the oor. If using
the fans in a grocery aisle applicaon, mount
the fan a minimum of 3 . from the edge of any
open reach in case to minimize the possibility of
introducing air into the case.

The free-hanging units are designed to hang
vercally and freely from the ceiling on hardware
capable of supporng a minimum of ve mes
the weight of the unit. Example - 1/4” (7 mm)
diameter steel bolt is rated at a 60 lb. (27 kg.)
load.
Hardware that may be used to hang the unit
includes, but is not restricted to: hooks, chains,
cables, carabiners, bridle rings, beam clamps
and bolts. Roof structure, building construcon,
electrical outlets/service and accessibility
will dene the appropriate hardware for each
installaon.
Tools Needed
T-30 Torx Driver (5/32” Hex); other tools include
T-20 Torx (7/64” Hex); T-25 Torx (1/8” Hex);
#2 Phillips Driver. All necessary tools to install
mounng hardware (varies from installaon to
installaon)
Installaon
Power Requirements
Refer to individual product data sheets or
reference the label installed within the fan nozzle.
Branch Circuit Protecon
The Designer Series fans do not include fuses for
branch circuit protecon. The branch circuit must
have a dedicated circuit breaker or similar device.
Naonal and local safety standards and electrical
codes may determine addional requirements for
installaon.
Fan Control
Refer to the installaon and operaon
instrucons for the specic fan control that was
purchased with your Airius Fan system.
In general, any model with a shaded pole or PSC
motor will be controlled over the mains power.
Any EC motor will be controlled by low voltage
0-10VDC. Airius oers several control interfaces
for manual, wireless, BACnet/IP control of EC
fans. For addional details, please reference our
website airiusfans.com
White - tachometer - 1 pulse/revoluon
Red - +10VDC
Yellow - Signal - accepts 0 to +10VDC
Blue - Common
To run an EC fan at full speed, connect the
yellow and red control wires.

Plug Wiring (230/277VAC)
120VAC cord is supplied with a molded three-
prong polarized/grounded plug. DO NOT
DEFEAT this SAFETY DEVICE or modify the plug
in any way.
230/277VAC no plug supplied. When ng
a plug always ensure that all relevant local
regulaons/electrical codes are understood and
followed with care - if in any doubt seek expert
guidance.
The power cord is a three-wire 18 AWG (or 16
AWG) 300VAC rated electrical cord UL rated
in North America (NA) as SJT or for CE/EU
compliance rated as HO5VV.
The three wires in the power cord are color-
coded to ensure proper wiring as follows:
BLACK or BROWN = HOT/ELECTRIFIED/LIVE
WHITE or BLUE = “N” NEUTRAL/RETURN PATH
GREEN or YELLOW-GREEN = GROUND/EARTH
The cord is aached to the fan motor via two
power leads with insulated 1/4” quick connects.
The cord is secured in the housing by a strain
relief and knoed inside the housing for
addional security.
Procedure for wiring the plug in a single-phase
electrical system:
Use CAUTION when wiring/aaching the plug
(Male Connector) to the Air Pear/Designer Series
system or when using any electrical device.
1Plug should be rated for 230VAC or 277VAC and t properly into outlet (female connector)
being used for power.
2
To avoid electrical shock, DO NOT plug device
into energized outlet unl all exposed wires
and connecng terminals are enclosed by plug
housing. See plug manufacturer’s instrucons.
3Locate the three stripped wires on the 300VAC rated power cord aached to the
unit where the outer cord insulaon jacket has
been removed. Wires are coded as follows: black
or brown is HOT/Live (the energized conductor),
white or blue is neutral “N” (the conductor used
for a return current path) and green or yellow/
green is ground/earth (the conductor to connect
to the earth).
4Using the plug manufacturer’s instrucons, locate the proper posions to aach the
color-coded wire to the color-coded or otherwise
appropriately labeled terminals on the plug.
5
Tighten all connecons. Reassemble plug
in accordance with plug manufacturer’s
instrucons.
To conrm electrical connuity, if possible, plug
the Designer Series system into an energized
outlet on the ground, similar to the outlet
installed in the ceiling, before permanently
mounng.
NOTE: The Designer Series System can be wired
directly to a juncon box but only by a qualied
electrician or similarly qualied person. Always
ensure that all relevant local regulaons/electrical
codes are understood and followed with care - if
in any doubt seek expert guidance. Check local
electrical codes. The preferred system is designed
with a plug for easy service and cleaning. An
on-o switch must be installed in the circuit to
be able to disable the power to prevent electrical
hazard when servicing the appliance.
Suggested Installaon Methods
Hardware that may be used to hang the unit
includes, but is not restricted to: Hooks, chains,
cables, carabiners, bridle rings, beam clamps and
bolts. Roof structure, building construcon and
accessibility will dene the appropriate hardware
for each installaon. Mount the fan as high in the
ceiling as possible and do not restrict airow into
the intake.
Aer ensuring the Designer Series system is
rmly aached and aer REMOVING YOUR
HANDS FROM THE UNIT, ONLY THEN is it safe
to plug the unit into the power source using the
approved plug to conrm funcon and electrical
connuity.
NOTE: Secure the power cord to the ceiling
structure as added security. The cord will act as
a safety leash and by securing it the possibility of
the plug accidentally coming out of the outlet is
greatly reduced. A 50 lb. (20 kg.) rated Zip Tie or
several wraps of mechanics wire are examples of
methods of securing the power cord.

Suggested Installaon Methods
1Remove the Designer Series from its box, then remove the plasc protecve bag. The bail
(handle) is aached via two Torx screws. Using
T-30 Torx driver, remove the torx screws and
loosely aach the bail.
2
Swing the bail to the vercal posion and
ghten the two Torx screws.
3
The Designer Series system is designed to
hang vercally and freely 12-to-18 inches,
or as close as possible, from the ceiling on
professionally installed hardware, for models
10/15/25, capable of supporng a minimum of
ve mes the weight of the Designer Series unit,
60 lb. (27 kg.). Example - 1/4” (7 mm) diameter
steel bolt is rated at 60 lb. (27 kg.) load.
A feature of the Designer Series system is
its exibility. Hardware that may be used to
hang the unit includes, but is not restricted to:
Hooks, chains, cables, carabiners, bridle rings,
beam clamps and bolts. Roof structure, building
construcon and accessibility will dene the
appropriate hardware for each installaon.

4
Aer ensuring the Designer Series system is
rmly aached, remove your hands from the
unit.
5
It is then safe to plug the unit into the power
source using the approved plug to conrm
funcon and electrical connuity.
6
NOTE: SECURE the power cord to the ceiling
structure as added security. The cord will act
as a safety leash and by securing it the possibility
of the plug accidentally coming out of the outlet
in the future is greatly reduced. A 50 lb. (20 kg.)
rated Zip-Tie or mechanics wire are examples of
methods of securing the power cord.
The graphic to the right is an example of hanging
the Designer Series unit:

Operaon
Heang Season
Within an enclosed building space, with minimal
air movement, hot lighter air rises to the ceiling
while cold heavier air falls to the oor creang a
temperature gradient. This condion will cause
excess energy use as the HVAC system ghts
to maintain the thermostat set point typically at
5 . above oor level. This inecient condion
can also cause great thermal discomfort for the
building occupants.
The Designer Series is an energy-ecient air
turbine, designed to connuously move a column
of air to the oor. A typical Designer Series
installaon includes a series of units mounted
just below the ceiling, evenly spaced throughout
a facility, working in concert to balance the air
temperature ceiling to oor and wall to wall.
As air circulaon improves and air temperatures
balance, your HVAC system will require less
and less energy to comfortably heat the work
area, reducing the energy consumpon of HVAC
systems up to 35% or more. Once started, the
enre process of “thermal equalizaon” will take,
on average, less than 24 hours.
All Designer Series fans are designed to run
connuously, year-round, to maintain thermal
equalizaon and general air movement.
Cooling Season
We tend to think stracaon occurs only in the
heang season, but actually the condion exists
year round. As you mechanically condion the air
to combat rising outdoor temperatures, combined
with minimal air movement, a large temperature
gradient can exist.
The HVAC system will consume more energy as
it ghts the temperature gradient, hot and cold
spots and short cycling compared to a properly
mixed space. Using the Designer Series system
will help alleviate the problem through thermal
equalizaon. Keeping the thermostats sased
longer and creang air movement that produces a
cooling eect on the skin will result in the ability
to raise the thermostat set points as much as 6°
F, yielding up to an 18% energy savings during
cooling seasons.
In non-air condioned spaces, the Designer
Series system can be used for spot cooling and
general air circulaon.
All Designer Series fans are designed to run
connuously, year-round, to maintain thermal
equalizaon and general air movement. The fan
speed can be maintained the same throughout
the year or increased for the summer months to
enhance the evaporave cooling eect if people
in the space nd this to be desirable.
Maintenance
Follow these easy steps to prevent any excess
dirt buildup and preserve the life of the product:
No lubricaon is required as bearings are sealed.
Cleaning:
Cauon: Staonary blades can cause injury!
Unplug unit from power source rst
to prevent possible electrical shock and
prevent injuries from spinning blades.
You may clean the plasc housing with
a damp cloth, using mild household
detergent only.
DO NOT use petroleum products,
thinners, solvents, ammonia, alcohols
or other chemicals to clean any part of
the Designer Series unit.
Note: If fan is not operang or any parts are
broken, contact manufacturer for replacement
informaon.
Troubleshoong
The Airius products are tested before they leave
the factory, resulng in an extremely low rate of
returns. However, mechanical devices do fail, and
