KEY RETENTION SYSTEM COMPONENTS

• Our fans are engineered with key features to prevent pieces of the fan from falling in the unlikely event of a catastrophic failure. Used together, these systems provide comprehensive protection of people, equipment and property.
• Install the safety cable on EVERY fan. The safety cable, if installed per Patterson Fan specifications, will prevent the fan from falling in the unlikely event that the mounting system should fail.
• The fan should never be run without a properly installed safety cable, which is supplied with every fan along with all required hardware. If the safety cable is not installed, the warranty will be voided.

MARK THE FLOOR TO ALERT PERSONNEL

• When mounting a fan in an area where materials may be elevated into its path, we recommend alerting personnel of the overhead location of fans by marking the floor.

WEIGHT CONSIDERATIONS

• If there is any uncertainty in the strength of the building structure, a professional structural engineer should perform a thorough evaluation of the building prior to purchasing the fans. Patterson Fan provides guidelines for mounting fans; however, it is the sole responsibility of the building owner and installer to ensure the safety of the mounting system, that the building structure is sound, and that the installation complies with all federal, state, and local codes.

WARNING

• If unusual oscillating movement is observed, immediately stop using the fan and contact your Patterson Sales Rep at 1-800-768-3985.

CHECK FEDERAL, STATE, AND LOCAL CODES

• Check all relevant codes to make sure that all product certifications, product listings, and building regulations are met. Code compliance is the responsibility of the installer.

WINDY CONDITIONS

• Fans should not be operated in windy conditions or installed in locations where it is frequently windy.

FAN SPACING, PLACEMENT, & CLEARANCE

SPRINKLER SYSTEMS AND FAN PLACEMENT

• In any installation where fire sprinklers are in place, the fan should not interfere with their correct operation. Fans should be located no less than 3 feet below a sprinkler, and placed in the center of nearest four sprinklers. Our industrial control panel can be connected to a fire relay system, which, in an emergency, will stop fans in case of fire.
• Prior to installing fans, review all codes applicable to sprinkler systems and fans to ensure code compliance and refer to NFPA 13 Standard from the National Fire Prevention Association. It is your sole responsibility to see that the installation is completed to code and that it is correct.

OTHER INFORMATION ON PLACEMENT AND SPACING

• If possible, avoid mounting fans directly below lights or skylights to avoid any strobe effect caused by moving airfoils. Please see chart below for recommended minimum and maximum hanging heights.
• If the building has a mezzanine, fans should be mounted so a person cannot reach a fan in any way from the upper level/deck. Make certain that fans are positioned so that the airfoil tips are at least 3 feet away from any area where a person may be able to extend outward to reach them.
• Fans should not be located directly beneath any air supply outlets or exhausting outlets. This includes air conditioning units and evaporative coolers. Such equipment can be used effectively in conjunction with HVLS fans but the discharge must be located outside of the swept area of the fan. Exhaust fan inlets or other return air points creating a negative pressure should not be within 1.5 times the diameter of the fan.

MAINTENANCE

• We strongly recommend that all equipment be included in your company’s preventative maintenance program. Prior to performing any maintenance on the fan, it MUST be disconnected from the power source by means of the separate lockable disconnect (provided).

AIRFOIL CLEANING

• Depending on the application of the fan, there can be quite a bit of dust or other particulates that cling to the fan’s airfoils. We recommend fan owners keep airfoils clean by having a maintenance person or skilled trade professional – who has experience using a lift – wipe the fan airfoils with a rag or sponge using hot water or regular cleaning solutions. Please do not use chlorine or any chemicals containing chlorine.

RETENTION SYSTEM CHECK

• Each fan must be installed with a retention system. The safety cable is attached to the motor and wraps around the building structure. The safety cable is an important part of the safety system and protects users if a catastrophic event occurs. It is critical for fan owners to ensure that it is intact and properly secured.

REPLACEMENT PARTS

• Please call your Patterson Sales Rep at 1-800-768-3985 for parts.

BAR JOIST MOUNTING

• Note: For other mounting options, please call your Patterson Rep at 1-800-768-3985.

1. Insert two bolts through one side of the bar joist mount and one beam clamp. Select the appropriate holes on the mount based on structure width; install bolts as close to bar joist as possible.
2. Place mount around bar joist and secure the remaining two bolts through the remaining beam clamp. Torque all four bolts to 32 ft-lbs.
3. Place the two top bolts of the downrod (image 3) into the bolt opening of the mount (image 4). Do not tighten completely.

MOTOR ASSEMBLY

• Note: To avoid damaging the motor during installation, do not remove protective plastic from the motor until it has been properly mounted.
• Note: If using an extended downrod, see page 11 for guy wire bracket installation before proceeding with motor assembly below.

1. Remove the two bolts on the bottom of the downrod. Slide motor shaft inside downrod so that motor leads are aligned with junction box above.
2. Line up safety ring bracket, downrod, and motor shaft bolt holes. Replace the two bolts.
3. With a level or plumb bob, make sure downrod is completely vertical. Torque all four downrod bolts (top and bottom) to 32 ft-lbs.

SAFETY RETENTION SYSTEM

• Note: This step is required. Failure to install the safety cable may void the manufacturer’s warranty.
• WARNING: Do not put too much tension on the safety cable. A small amount of slack is needed for the safety cable to properly function. Avoid sharp edges.

1. Wrap safety cable around beam or building structure.
2. Run safety cable through the holes in top of safety ring bracket and around downrod.
3. Overlap safety cable and secure with cable clamps.

GUY WIRE ASSEMBLY

WARNING: If you order an extended downrod, guy wire installation becomes required for safe fan operation.

1. During Step 2 of MOTOR ASSEMBLY, add guy wire brackets to the top bolt of the motor shaft. The guy wire brackets come with extra washers that should be placed between the guy wire brackets and safety ring bracket. Bolt should be torqued to 32 ft-lbs per Step 3 of MOTOR ASSEMBLY.
2. Using the quick links, connect the turnbuckles to the outer holes of the guy wire brackets.
3. Loosen jam nuts and extend turnbuckle.
4. Run four guy wires to ceiling structure, keeping the angle less than 45° for maximum stability. Attach guy wires to ceiling structure using provided beam clamps and thimble.
5. Remove slack and secure with cable clamps.
6. Once all guy wires are in place, use turnbuckles to take out any remaining slack. Periodically check the fan assembly with a level to ensure it remains in the vertical position. Continue adjusting by means of the turnbuckles until all cables are satisfactory. Guy wires should be taut, but not over stressed. Recheck all cable clamps for tightness.
7. Tighten all jam nuts. This step is required. Failure to install the guy wires properly may void manufacturer’s warranty and become a safety hazard.

BLADE ASSEMBLY

1. Insert wingtips into the end of the blades and lock into place with screw.
2. Remove blade bolts from tang. Loosen safety strap bolts and insert blade onto tang. Install the two blade bolts and double washer from below as shown Image 17. Torque to 16 ft-lbs.
3. Install washer and nut on top of blade bolt. Torque to 16 ft-lbs. Do not torque blade bolts and nuts at the same time.
