Installation
Qualified or trained personnel should install the blower. Electrical rotating equipment
can result in property damage, serious injury, or death, when improperly installed.
Equipment should be installed in accordance with the National Electric Code, local
codes, and/or with the “NEMA MG2 Safety Standards for Construction and Guide for
Selection, Installation and Use of Electric Motors and Generators”.
1. Position Blower
Locate in position where ambient air temperature available for the motor cooling fan
does not exceed 90ºF or 32ºC.
Blower Systems
Blowers not in Enclosures or Part of JetTunnel™ or Premier™ Systems should be
positioned by lifting from the motor lifting eye on top of motor or the motor stand.
Do not lift the blower by the volute housing.
The blower should be located in a place where the blower intake and motor cooling fan
are not obstructed and where the filter may be easily serviced. The air intake inlet
must be a minimum of 10” or 250mm from the nearest obstruction and the motor
cooling fan is a minimum of 2” or 5cm from the nearest obstruction.
The blower is designed to rest on its motor stand or enclosure legs. The blower may
not be positioned on any other side. Contact JetAir Technologies, LLC for unusual
positioning requirements.
Bolt your JetAir Technologies blower in place to a rigid floor by the mounting legs.
Use a minimum four (4) mounting bolts. Note: The JET-3™ blower weighs ~95lbs.

V1.5 ©2009 JetAir Technologies, LLC - 6 -
Enclosed Systems
If your blower is installed in an Enclosure, locate and level enclosure and place in
location where the blower intake is not obstructed. The air intake, located on the
bottom of the enclosure, must be a minimum of 10” (250mm) off the floor and away
from any other obstruction. The high vacuum created at the intake can easily aspirate
water and debris if the enclosure is less than 10” (250mm) off the floor resulting in a
prematurely plugged or saturated filter and subsequent blower damage.
Enclosure should be positioned allowing for front panel door swing, easy controls
access and an unobstructed air passage for blower outlet on rear of enclosure.
JetTunnel™ Systems
2.Install Air Filter
Improper filtration or operating the blower without a filter will void the warranty.
Canister Filters and Panel Filters are available for JET-3™ JetAir Blowers and JET-3™
Stainless Steel Blower Enclosures respectively for normal operating environments and
HEPA applications.
Warning: Do not operate blower without filter in place or filter lid unattached
3.Install Air Components and Connect to Blower. Blower outlet
is Ø4” or Ø102mm. Contact JetAir for a variety valves, hoses, and fittings that may
suit your application.

4. Connect Incoming Line Power to the Adjustable
Frequency AC Drive
Only use a qualified electrician and follow all applicable electrical codes.
Refer to the AC drive nameplate for correct power supply requirements. Based on the
drive nameplate refer to the included Adjustable Frequency AC Drive User Manual
for all input and output wiring specifications. Be sure to follow all “General
Precautions”, “AC Supply Source Considerations”, and “Input Power Conditioning”
Sections found in the Manual, otherwise product life may be shortened and the
warranty may be voided.
Basic Connection Parameters:
a. Connects 3 Phase AC Power + Ground from Line Power to AC Drive
b. Consult AC Drive Manual for input power quality requirements
c. Input Power is dependent on AC Drive HP requirements – see AC Drive
specification
d. Wire Gage – AWG is dependent on local code and/or NEC tables and is
the responsibility of the customer to specify, procure, and install.
e. The customer is responsible for supplying stable and clean incoming
power. Depending on quality of incoming power, the customer may be
responsible for installing a Line Reactor or other power conditioning
equipment to protect the AC Drive.
f. “Delta Ungrounded” line power requires a Line Reactor
ATTENTION: National Codes and standards (NEC, VDE, BSI, etc.) and local codes
outline provisions for safely installing electrical equipment. Installation must comply
with specifications regarding wire types, conductor sizes, branch circuit protection and
disconnect devices. Failure to do so may result in personal injury and/or equipment
damage.
ATTENTION: To avoid a possible shock hazard caused by induced voltages, unused
wires in the conduit must be grounded at both ends. For the same reason, if a drive
sharing a conduit is being serviced or installed; all drives using this conduit should be
disabled. This will help minimize the possible shock hazard from “cross coupled” power
leads.
The Powerflex 70 AC Drive User Manual is available online at:

(contact JetAir for instructions if not preconfigured).
8. Failure to install proper cable or connect motor thermal switch voids warranty.
WARNING: The JET-3™ motor is a special ‘high-speed’ motor that is matched
specifically to the JetAir supplied Adjustable Frequency AC Drive (i.e., frequency
inverter or variable frequency drive) shipped with the motor. The motor must always
be powered and controlled by the JetAir supplied Adjustable Frequency AC Drive. Use
of any other AC Drive, other than the one supplied with the motor, voids warranty.
DO NOT, under any circumstance, bypass the AC Drive and connect the JET-3™ high
speed motor directly to line power. This will void the warranty and will destroy the
motor. Use only a qualified electrician only to make all connections.
Note that the Jet-3 Blower Motor is configured to run in Delta for all Jet-3 applications:
10, 15, and 20HP.
Connect customer supplied VFD Grade Cable (consult local electrical codes for proper
AWG - wire gage) between the Adjustable Frequency AC Drive and JetAir Blower Motor

AC Drive Output Power and Motor Thermal Protection Switch Connections to
Jet-3 Motor Junction Box

V1.5 ©2009 JetAir Technologies, LLC - 15 -
Connect a twisted pair of control wires (20 – 24 AWG) from the Motor Thermal
Protection Switch to terminals No. 8 and 11 on the AC Drive. This is a normally closed
circuit (N.C.) that will open when motor winding temperatures exceed a safe limit and
generate an ‘Aux Fault’ in the AC Drive (shutting the drive and blower down). When
temperatures drop to a safe level, the switch closes. Note all drive faults must be
manually cleared before the drive will restart. It is important that the Motor Thermal
Protection Switch is wired and configured in the AC Drive to protect the motor. Not
wiring the switch to the AC Drive will void the warranty on the motor.
Note and follow all Safety Precautions and Warnings.
Unauthorized customer programming of the Adjustable Frequency AC Drive voids drive
warranty.
Never reset the AC Drive to defaults using the ‘Reset to Defaults’ feature under any
circumstances without contacting JetAir first for approval – Default Nameplate
parameters will do irreparable harm to the motor.

V1.5 ©2009 JetAir Technologies, LLC - 16 -
Start-Up
Wear safety glasses and earplugs when working on the blower system, airknife, or
discharge nozzles of your JetAir Technologies Blower System.
WARNING: The Adjustable Frequency AC Drive maybe programmed to automatically
start the when line power is turned on to the Adjustable Frequency AC Drive. In this
case, the blower will start and accelerate to the programmed speed as specified for
your application. If you are not sure of the configuration, please contact JetAir
Technical Support at 805-654-7000.
1.Start Methods
Following proper connection of line power to the AC Drive and from the AC Drive to
the Blower Motor the blower is ready to start. Specific methods to Start and Stop the
blower may vary depending on the application. Typical start configurations include:
A. Start / Stop blower when power is applied or removed from the AC Drive
B. Start / Stop blower using enclosure mounted ‘on-off-auto’ switch
C. Start / Stop blower by using HIM keypad on Drive or Enclosure Door
D. Start / Stop blower using AC Drive installed Comm Card
E. Start / Stop blower using customer PLC
Frequent Start / Stop Warning: Contact JetAir immediately if you application requires
the blower to start / stop more than 3 times / hour as this requires an idle speed
option to keep the blower motor from overheating.
Consult the Powerflex 70 AC Drive Parameter listing provided and programmed into
your AC Drive. Consult the Powerflex 70 User Manual for a comprehensive list of all
input wiring options for drive and speed control. The Start method and associated
parameters were entered and tested with your Blower by JetAir prior to shipment.
The AC Drive configured with the blower is normally preprogrammed by JetAir to start
and accelerate to your specific operating speed in 30 seconds (acceleration times may
vary depending on application requirements). If you have any questions about your
configuration or wish to change control parameters, please contact JetAir for
assistance.
Changing factory programmed parameters or ‘resetting to defaults’ without consulting
JetAir may result in permanent damage to the AC Drive and Blower and may void your
warranty.
2.Check Motor Rotation
The blower should be rotating counter-clockwise while looking from the impeller side
of the blower. Check this by ‘bumping’ the motor using the Start command from the
blower and observing the rotation. Rotation of the cooling fan on the rear of the
motor may also be used. Note that correct rotation of the cooling fan is ‘clockwise’

V1.5 ©2009 JetAir Technologies, LLC - 17 -
Impeller rotation must be counter clockwise as
indicated on the volute as viewed from the front
intake side.
The blower must rotate counter-clockwise when viewed from the impeller or intake
side of the blower. Check rotation by ‘bumping’ the motor for a few seconds using
the Start command from the blower and then observing the impeller rotation.
Rotation of the cooling fan on the rear of the motor may also be used in the event the
intake side of the blower cannot be observed due to mechanical restrictions. Note
that correct rotation of the cooling fan is ‘clockwise’ when viewed from the backside of
the motor.
Correct motor rotation provides optimum performance. However, substantial flow and
pressure will still be achieved when running backwards despite significant efficiency
loss.
Backwards impeller rotation will also cause additional damaging vibration on high-
speed motor. Backwards running of blower will invalidate warranty.
If impeller rotation is clockwise (incorrect), then change to counter clockwise (correct)
by switching input power leads from the Adjustable Frequency AC Drive to the motor
on terminals V1 and U1 in the motor junction box. Note: switching incoming (i.e.,
line) power leads to the Drive will not affect motor rotation.
3.Connect Air Components & Filter / Check kilowatt Use
Prior to checking power consumption and running the blower at operating speed make
sure all intake and exhaust plumbing connections are in place. Higher than expected
kilowatt or horsepower usage beyond drive rating may generate a Hardware Over-
Current fault. On a new installation this typically indicates excess flow as a result of
an ‘open’ system not connected to air components on the intake and exhaust: hose,
valves, dividers, and/or air knifes.

V1.5 ©2009 JetAir Technologies, LLC - 18 -
Service Procedures
Wear safety glasses and earplugs when working on the blower system, Airknife,
JetBlast™, or any other discharge nozzles of your JetAir Technologies Blower System.
Follow all National, State, Local, and Company codes and policies when disconnecting
the electrical power at the motor, junction box, fuse box or circuit breaker before
working on your system. Take special precautions to make sure that power cannot be
turned on while you are working on the blower. Use an approved lock out / tag out
system.
Review Adjustable Frequency AC Drives Safety Precautions in User Manual. Note:
Adjustable Frequency AC Drives can retain an electrical charge for up to three minutes
after disconnecting power.
Blower units that are damaged and unable to run because of overheated motor,
impeller damage, impeller non-rotation or other problem must be factory serviced.

Filter Maintenance
General Recommendations
JetAir Technologies’ Air Filters are inexpensive and easy to change. Filters should be
changed based on the maintenance schedule below at a minimum or when inlet Filter
Change Gage indicator needle moving from the green to red zone. Customers in
unusual environments and special situations may need to change filters more
frequently. Remember to routinely maintain or change blower intake filters as the
blower warranty is voided if a blower is operated without a filter or improperly
maintained filter.
Filter Maintenance Schedule
Filtration is critical to performance, longevity, and enforcing the warranty on JetAir
Industrial Blower Systems. The following are general guidelines for standard
polyester canister filter replacements in various commercial environments. Request a
JetAir sales engineer for specific guidelines for your application and environment:
•Beverage – Soda and Juices 30 days
•Beverage – Beer 60 days
•Industrial - Oil Mist 60 days
•Industrial – Dust 90 days
•Textile - Fabric debris 120 days
Canister Filter Change Procedure
1. Change filter by removing the top filter cover knob. Then remove the filter
cover and remove the used filter off. Reverse process to install new filter.
(See page 4.)
Panel Filter Change Procedure for Stainless Steel Enclosure:
1. Change filter by opening the door of the blower enclosure and remove old
filter. Slide new filter into position along guide rails near the top of the
enclosure. Note air flow direction arrow on the side of the panel air filter.
Correct air flow is from the top of the enclosure down into the blower
compartment.
2. Make sure the access door is closed and securely fastened.
3. Inspect enclosure at blower outtake and make sure outtake gasket is in place
between the enclosure wall and blower outtake. This seal assures no air will
bypass the filter into the blower compartment.
