READ AND SAVE THESE INSTRUCTIONS
The purpose of this manual is to aid in the proper installation and operation of fans
manufactured by Soler & Palau USA. These instructions are intended to supplement good
general practices and are not intended to cover detailed instruction procedures, because of
the wide variety and types of fans manufactured by Soler & Palau USA.

INSTALLATION, OPERATION AND MAINTENANCE MANUAL
INTRODUCTION:
DO NOT INSTALL, USE OR OPERATE THIS EQUIPMENT UNTIL THIS MANUAL HAS BEEN READ AND
UNDERSTOOD. READ AND SAVE THESE INSTRUCTIONS FOR FUTURE USE.
It is the responsibility of the purchaser to assure that the installation and maintenance of this equipment is handled by
qualied personnel experienced in such work and equipment.
Contact your local representative should you need further information.
SHIPMENT AND RECEIVING:
Prior to shipment, all fans have been thoroughly inspected and tested.
All equipment shipped from Soler & Palau USA is skidded 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 S&P representative 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 that 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, BASE,
PROP, WHEEL, 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 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 should be rotated monthly. 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 at 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 special platform and be placed as near as possible to,
or over, a solid wall or column.
Supports for suspended fans must be crossbraced for live load support to prevent side sway.
Use guy wires to help secure root units if excessively windy conditions prevail.

1. CAUTION! This fan contains rotating parts and requires special service. Appropriate safety precautions
should be taken during installation, operation and maintenance.
2. WARNING! Do not install or operate this fan in an environment or atmosphere where combustible or
ammable materials, gasses or fumes are present, unless it was specically designed and manufactured
for use in that environment. Explosion or re 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 in 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 that 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 qualied
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/
motor position as required to achieve necessary clearances.
11. WARNING! Check all setscrews and keys. Tighten as necessary prior to fan startup.
12. On roof units, anchor the fan securely to the curb. Anchoring through the vertical portion of the curb cap
ange is recommended. Use a minimum of four lag bolts or other suitable fasteners.
13. Due to the general nature of its applications, the basic air mover is available with protective guards and/or
other devices for required operating safety as with most installations of rotating machinery. Before operating
the basic unit in any of its applications 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:
Lock out the power source.
Tighten all bolts and setscrews securely. NOTE THAT ALL BOLTS AND SETSCREWS 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
wheel or propeller should not strike the housing.
No initial lubrication is required. Motors have been pre-lubricated by motor manufacturer.
Arrows to show direction of rotation and airow 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 airow and the motor
connections must be altered to correct rotation.

Lock out the power source before the installation of all accessories.
Fan electrical power can now be applied and special attention should be given to determine if motor is working
properly. At this time, with air system in full operation, with guards attached, it is well for the electrician to measure
the operating amperage of the motor and compare with the nameplate rating to determine that the motor is operating
under safe load conditions.
The fan should not need balancing, as it was balanced at the factory to meet stringent vibration levels before
shipment. However, there are several things that may cause vibration, such as rough handling in shipment and
erection, weak foundations, and alignments.
MAINTENANCE:
1. Before performing any maintenance on the fan, be sure power is turned off and locked in the OFF position at
the service entrance before servicing the fan.
2. Ventilators should be carefully checked at least once a year. For critical or rugged applications, a routine
check every two or three months is suggested.
3. All motors supplied with Soler & Palau USA ventilators carry a one (1) year warranty from date of shipment.
For repairs within the warranty period, the motor must be taken to the motor manufacturer’s authorized
service dealer. Contact your representative for additional warranty details.
4. A periodic motor check should consist of spinning the motor shaft with the power off to be sure the motor turns
freely.
5. Check sheave set screws to ensure tightness. Proper keys must be in keyways.
6. Do not readjust blade pitch or fan RPM. If sheaves are replaces, use only sheaves of identical size and type.
7. During the rst few months of operation, it is recommended that the setscrews be checked to assure they are
tight.
8. The rotating wheel or propeller requires particular attention in most applications since materials in the air
being handled can build up on the blades to cause destructive vibration; and may also corrode and/or erode
the blade metal to weaken the structure of the propeller. Regular inspection and corrective action at intervals
determined by the severity of each application are essential to good service life.
MOTORS:
The fundamental principle of electrical maintenance is KEEP THE MOTOR CLEAN AND DRY. This requires periodic
inspection of the motor. The frequency depends upon type of motor and the service.
We recommend periodic checks of voltage, frequency, and current of a motor while in operation. Such checks assure
the correctness of frequency and voltage applied to the motor, and yield an indication of the fan load. Comparison
of this data with previous data will give an indication of the fan performance. Any serious deviations should be
investigated and corrected.
Lubricate integral horsepower motors per the motor manufacturer’s recommendations. Lubrication frequency depends
on the motor horsepower, speed, and service. Use compatible greases.
1. All motors carry a one (1) year warranty from date of shipment. For repairs within the warranty period, the
motor must be taken to the motor manufacturer’s authorized service dealer. Contact your representative for
additional warranty details.
2. A periodic motor check should consist of spinning the motor shaft with the power off to be sure the motor turns
freely.

REPAIR PARTS:
3. Fan Blades – Repair of individual fan blades or propeller assemblies is not recommended. Contact factory
with blade size, number of blades, bore size, motor HP, air ow direction, rotation, fan RPM or sheave sizes
and any order/tag information that is available for replacement.
4. Misc. Parts – Not available from local trade channels should be returned for repair or replacement. Be sure to
obtain return tags or authorization before shipment.
5. Electric Motors – Repair or replacement of motors is normally performed by a repair station authorized by the
manufacturer. Contact your representative or the factory for locations nearest to you. DO NOT ship motor to
the factory without specic authorization.
