Assessment Of Installation Site
Prior to the installation of industrial fans, the project personnel must assess and communicate any civil construction or
installation conditions, ground facilities, locations of on-site power supplies, on-site voltage, wiring distances, and the
installation locations of control boxes and fans with installation engineers.
Parts Inspection
In order to ensure that the installation process goes smoothly, it is necessary for the project team to make an inventory of
provided materials in combination with a list of required tools (not included), while checking the quantity and quality of each one.

According to the diagram, install the transition
fitting on the steel I-beam, and then lock the
fastening screws to complete the installation.
NOTE
• Illustrations are for explanatory purposes only and are not drawn to scale.
• If you are installing the fan to a building structure other than I-Beam, you may need to purchase an
additional installation bracket. Examples requiring a separate installation kit include: Z-Purlins, Solid
Beam, and Angled I-Beam.
• Extensions brackets are available to drop the fan height lower. They are available in 20 inches (500mm),
32 inches (800mm), and 48 inches (1200mm) sizes.
After confirming the installation location and ensuring all parts,
tools, and equipment are received, the next step is installing the
transition fittings. The process could be different according to
your building structure.

secure it with the tiger claw
to lock it in place.
STEP 5
The next step in the installation process includes using the
provided wire rope to form an additional safety feature ensuring
the fan is secure in the event the fan becomes unsteady due to
natural disaster or building structural age. Use the supplied tiger
claws to secure the wire rope to the beam. See the diagram
below that illustrates proper rope placement.

After the fan has been installed and secured
to the structure, the final step in the process
is to install the Honeywell Control Box to the
wall and wire it to the fan motor. Make sure
to choose a location that is not accessible to
children. The control box is used to operate
the HVLS fan, change the fan speed, or
change the direction of the fan blades. See
the diagrams below and the included
Honeywell User Manual for proper installation
and wiring procedures.
Please see the following connection
diagrams for power and control wiring.
Please refer to the Honeywell User
Manual for specific guidelines.

Used to display real-time
information, to access
and exit parameter edit
mode and to store
parameter changes.
Used to reset a
tripped drive.
When in Keypad
mode is used to Stop
a running drive.
When in keypad mode,
used to Start a stopped
drive or to reverse the
direction of rotation if
bi-directional keypad
mode is enabled.
Used to increase speed in
real-time mode or to
increase parameter values in
parameter edit mode.
Used to decrease speed in
real-time mode or to
decrease parameter values
in parameter edit mode.
Use the control box to operate the fan’s speed using the UP or DOWN keys on the control panel. Any
commissioning or fault codes will appear in the display window on the control panel.
Fan Rotation
The fan blades should rotate counterclockwise as viewed from below the fan. To maximize the energy savings
for supplemental heating and cooling systems, operate the fan year-round. The most effective method is listed
below.
Heating Season
Set the fan on the slowest speed setting to push the
hot air back down from the ceiling without causing a
draft. Additionally, lower your thermostat setting by a
few degrees to create a comfortable environment while
still saving energy costs.
Cooling Season
The fan speed can be adjusted to a higher setting to
provide a continuous breeze and constant air
movement. By increasing the thermostat’s setting by
2-7°and running the fan only when people are
present in the building, you can reduce energy costs.

NOTE
Please refer to chapter 5 in the Honeywell Control Box User Manual that is
included with your fan for detailed Control Box operation instructions.

Control Panel Codes
Fault Code No. Description Suggested Remedy
00 No Fault Not required.
Check external brake resistor condition and connection wiring.
The drive has tripped to prevent damage to the brake resistor.
The drive has tripped after delivering >100% of value in P-08 for a period of time to
prevent damage to the motor.
Check the supply voltage is within the allowed tolerance for the drive. If the fault
occurs on deceleration or stopping, increase the deceleration time in P-04 or install
a suitable brake resistor and activate the dynamic braking function with P-34.
The incoming supply voltage is too low. This trip occurs routinely when power is
removed from the drive. If it occurs during running, check the incoming power
supply voltage and all components in the power feed line to the drive.
The drive is too hot. Check the ambient temperature around the drive is within the
drive specification. Ensure sufficient cooling air is free to circulate around the drive.
Trip occurs when ambient temperature is less than -10°C. Temperature must be
raised over -10°C in order to start the drive.
E-trip requested on digital input 3. Normally closed contact has opened for some
reason. If motor thermistor is connected check if the motor is too hot.
Check communication link between drive and external devices. Make sure each
drive in the network has its unique address.
Check incoming supply phases are all present and balanced.
Check incoming power supply phases are present and balanced.
Press the stop key. If the fault persists, consult you supplier.
Check the analog input connection(s).
Press the stop key. If the fault persists, consult you supplier.
Connected motor thermistor over temperature, check wiring connections and motor.
Check / replace the cooling fan.
Drive ambient temperature too high, check adequate cooling air is provided.
Indicates a fault on the output of the drive, such as one phase missing, motor phase
currents not balanced. Check the motor and connections.
The motor parameters measured through the autotune are not correct. Check the
motor cable and connections for continuity. Check all three phases of the motor are
present and balanced.
Check the incoming Modbus RTU connection cable.
Check that at least one register is being polled cyclically within the timeout limit set in
P-36 Index 3.
Check the incoming CAN connection cable. Check that cyclic communications take
place within the timeout limit set in P-36 Index 3.
Check for short circuits on the motor and connection cable.
NOTE Following a trip, the drive cannot be immediately reset. A delay time is inbuilt,
which allows the power components of the drive time to recover to avoid damage.
Instantaneous Over current on the drive output. Excess load or shock load on the
motor.
