FORM 1510

The purpose of this manual is to aid in the proper installation and operation of fans supplied by Carnes. Because of the
wide variety and types of fans manufactured by Carnes, the instructions are intended to supplement good general prac­tices and are not intended to cover detailed instruction procedures.

It is the responsibility of the purchaser to assure that the installation and maintenance of this equipment is handled by qual­ified personnel experienced in such work and equipment.

Contact your local Carnes representative should you need further information.

SHIPMENT AND RECEIVING:

Prior to shipment, all fans have been thoroughly inspected and tested.
All equipment shipped from Carnes is boxed or crated to fully comply with trucking requirements. Inspect all shipments carefully for

damage. THE RECEIVER MUST NOTE ANY DAMAGE ON THE CARRIER’S BILL OF LADING AND FILE A CLAIM IMMEDIATELY
WITH THE FREIGHT COMPANY, IN THE CASE OF ANY DAMAGE. Keep a record of all equipment received, including inspection
details and date of receipt, because of the possibility of partial shipments.

If you receive damaged goods, contact your Carnes sales representative or the factory for repair or replacement service.

HANDLING:

Handle your equipment with caution. Some fans are provided with lifting lugs or holes for easy handling. Others must be handled using
nylon straps which protect the fan’s coating and housing. Spreader bars should be used when lifting large parts.

Fans should be lifted by using straps around the fan housing only. DO NOT LIFT FANS BY THE MOTOR, MOTOR BASE, PROP OR
FLANGES.

Roof ventilators should be lifted by using straps around the fan housing or base only. Spreader bars should also be used to avoid dam­age to stack caps or hoods. DO NOT LIFT ROOF VENTILATORS BY THE STACK CAP OR HOOD. On hooded units, disassemble
the stack from the hood when lifting. Upblast models may be lifted assembled.

STORAGE:

If fans are stored for any length of time, they should be stored in a clean, dry location to prevent rust and corrosion.

Outdoor storage is

not recommended

. When outdoor storage is necessary, they should be protected from the elements as best as possible. Cover the

fan inlet and outlet and keep motors dry and clean.
For extended storage (more than 3 months), motor shafts and bearings should be rotated monthly. If stored greater than 6 months,

bearing grease in motor and fan should be purged and replaced with compatible grease. Re-check belts for proper tension. Storage
records should be kept to assure proper maintenance. The factory can advise warranty centers to provide motor and bearing service if
needed.

INSTALLATION:

Roof ventilators should always be mounted to a flat, level, solid and rigid structure. Particular caution should be exercised when
installing fans on metal buildings. Be sure wall or roofs are capable of supporting the fan(s). Walls/roofs not supported correctly will
cause vibration that could cause damage or injury.

Fans mounted off ground level should be rigidly mounted to a structural platform and placed as near as possible to, or over, a solid wall
or column.

Support for suspended fans must be crossbraced for live load support to prevent side sway.
Use guy wires to help secure roof units if excessive windy conditions prevail.

1. CAUTION! This fan contains rotating parts and requires electrical service. Appropriate safety precautions should be taken dur-

ing installation, operation and maintenance.

2. WARNING! Do not install or operate this fan in environment or atmosphere where combustible or flammable materials, gasses

or fumes are present unless it was specifically designed and manufactured for use in that environment. Explosion of Fire can result.

Explosive, corrosive, high temperature, etc. conditions may require special construction, inspection and maintenance. It is neces­sary to observe the fan manufacturer’s recommendations and limitation concerning the type of material to be handled by the fan
and its application to special conditions.

3. When ventilator is designed to be mounted on a curb, the curb should be securely installed prior to fan installation.

4. A damper, if used, should be securely mounted within the curb or wall in a manner which allows free and unobstructed operation.

5. CAUTION! All electrical work must be done in accordance with local and/or national electrical codes as applicable. If you are
unfamiliar with methods of installing electrical wiring, secure the services of a qualified electrician.

6. WARNING! This product must be grounded.

7. DANGER! Make sure power is turned off and locked in the OFF

position at the service entrance before installing, wiring or

servicing fan.

8. CAUTION! Before wiring the motor, check the supply voltage against the motor nameplate voltage. High or low voltage can
damage the motor and void the motor warranty.

9. WARNING! Be sure to keep all wiring clear of rotating or moving parts.

10. WARNING! Before starting the fan, turn the wheel to assure it rotates freely. If needed, adjust the wheel/shaft/bearing/motor
position as required to achieve necessary clearances.

11. CAUTION! On belt drive units, assure belts are tensioned and aligned properly. (See Maintenance section.)

12. WARNING! Check all set screws and keys. Tighten as necessary prior to fan start-up.

13. On roof units, anchor the fan securely to the curb. Anchoring thru the vertical portion of the curb cap flange is recommended.
Use a minimum of four (4) large bolts or other suitable fasteners.

14. Due to the general nature of its applications, the basic air mover is available with protective guards and/or other devices for
required operation safety as with most installations of rotating machinery. Before operating the basic unit in any of its applica-

tions determine requirements for such guards and/or devices needed for protection against accidental contact with moving parts or

against injury to nearby personnel or critical equipment due to accidental rupture of fast moving parts.

START-UP

Lockout the power source.

Tighten all bolts and setscrews securely and, on belt drive fans, check sheave alignment and belt tension. Tighten belts if necessary.
NOTE THAT BOLTS, SETSCREWS AND BELTS SHOULD BE TIGHTENED AFTER TWO DAYS OF INITIAL OPERATION.

Clearance should be checked all around between wheel or propeller tips and the housing before starting up. The propeller should not
strike the housing.

No initial lubrication is required. Motor and fan bearings have been pre-lubricated by motor manufacturer. Arrows to show direction of
rotation and airflow are attached to the fan housings.

After the electrical connections are completed, apply just enough power to start the impeller as indicated by the directional arrows on
the unit. If the impeller is turning the wrong direction, it will not deliver rated airflow and the motor connections must be altered to cor­rect rotation.

Lock out

the power source before the installation of all accessories.
