January 2024 6022221C - Direct Drive HVLS Fan UM 9
Introduction
Installation of the equipment must comply with local and national electrical codes and must be in
accordance with ANSI/NFPA 7-1999.
Do not use this fan until you have received proper training. Improper use could result in property
damage, bodily injury and/or death. Read and follow Operating Instructions on page <?> before
use. If you do not understand the instructions, ask your supervisor to explain them to you or call
your local distributor.
DO NOT USE THE FAN IF IT APPEARS DAMAGED OR DOES NOT OPERATE PROPERLY.
Inform your supervisor immediately.
Do not operate the fan until all personnel, building structure, and equipment are clear of all
moving parts and exclusion zones. Install guards as required.
To reduce the risk of electrical shock, do not expose to water or rain.
Support directly from building structure. Do not install the fan unit onto structure of insucient
strength. Consult a professional engineer or registered architect. Improper installation of the fan
could result in death or serious injury.
Before service, inspection, or cleaning, make certain the power is disconnected and properly
locked out.
If the fan does not operate properly using the procedures in this manual, BE CERTAIN TO
REMOVE POWER FROM THE UNIT AND LOCK-OUT THE DISCONNECT ON THE POWER
CIRCUIT. Call your local distributor for service.
Keep your body clear of moving parts at all times.
All electrical troubleshooting and repair must be done by a qualied technician and meet all
applicable codes.
If it is necessary to make troubleshooting checks inside the VFD box with the power on, USE
EXTREME CAUTION. Do not place ngers or un-insulated tools inside the enclosure. Touching
wires or other parts inside the enclosure could result in electrical shock, death, or serious injury.
Variable Frequency Drive (VFD) fan controllers contain high voltage capacitors. Before working
on the fan controller, ensure isolation of the main voltage supply and verify voltage has bled o
prior to beginning work. Failure to do so may result in death or serious injury.
If you have problems or questions, contact your local distributor for assistance.

Introduction
To reduce the risk of injury to persons, install fan so that the blades are at least 3.05m (10’)
above the oor.
Installation work and electrical wiring must be done by qualied person(s) in accordance
with all applicable codes and standards.
When cutting or drilling into wall or ceiling, do not damage electrical wiring and other hidden
utilities.
Exercise caution and common sense when powering the fan. Do not connect the fan to a
damaged or hazardous power source. Do not attempt to resolve electrical malfunctions or
failures on your own.
When service or replacement of a component in the fan requires the removal of disconnection of
a safety device, the safety device is to be reinstalled or remounted as previously installed.
Risk of re, electric shock, or injury to persons during cleaning and user-maintenance.
Disconnect the fan from the power supply before servicing.

January 2024 6022221C - Direct Drive HVLS Fan UM 17
Installation Considerations
Failure to maintain exclusion zones outlined in this section could result in fan failures, including
blade separation, which could result in death or serious injury.
DO NOT operate fans when physical obstructions or HVAC air ows extend into exclusion zones.
Regularly inspect fans to ensure exclusion zones remain clear of interference before operating
the fan.
All fan blade parts must be greater than 3’ from all obstructions including lights, cables, sprinklers,
and other building components and greater than one half (1/2) fan diameter from any wall to the end
of the blade.
ROOF ANGLES
For roof angles in excess of 20°, consult the factory. The extension lengths shown are minimum
recommendations only, based solely o󰀨 roof pitch and fan diameter. Other considerations, such as
placement of lights, sprinkler systems, HVAC systems, etc., must be evaluated when determining
extension requirements. The fan blades must be at minimum 10’ above the oor.

CLEARANCE FROM HVAC EQUIPMENT
For applications near HVAC equipment, such as di󰀨users, radiant heaters, exhaust fans, louvers, etc.,
the HVLS fan must be installed at minimum distances. Refer to the gures below. Fans located above
HVAC equipment must have a minimum clearance of greater than or equal to 1 fan diameter. See
Figure 2.

CLEARANCE FROM SOLID OBSTRUCTIONS
For applications near solid obstructions, the HVLS fan must be installed at minimum distances.
Fans located near solid obstructions, such as walls racks or columns greater than 1FT wide, should
have a minimum distance of one half (1/2) fan diameter from the end of the blade.
Fans located above solid obstructions, such as racks, walls, etc. must have a minimum distance of
greater than or equal to 1/2 fan diameter above the obstruction. The obstruction below must also be
less than or equal to 1/4 fan diameter inside the fan blade arc. See Figure 4.
