Introduction

Handling

Storage

Shipment and Receiving

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 hood when lifting. Upblast models may be lifted assembled.

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

sion. Outdoor storage is not recommended. When outdoor storage is necessary, fans should be protected from the

elements as completely as possible. Cover fan inlets and outlets and keep motors dry and clean.

For extended storage (more than 3 months) motor shafts and bearings should be rotated monthly. If stored longer

than 6 months, bearing grease in the 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 war-

ranty 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 roof is capable of supporting the fan(s). Fans mounted on walls or roofs and 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 be placed over or as near as possible to a solid wall or column.

WARNING: Especially check three-phase units for rotation. For three-phase, rotation can be changed by interchanging any two of the three line leads. If the unit is checked on temporary wiring, it should be rechecked when permanently installed. Motor burn-out or tripped overload protection devices are usually the result of wrong rotation. 5. Electrical Input Check: Perform check of fan ampere draw and verify that motor nameplate amps are not exceeded.

9. Check sheave setscrews to ensure tightness. Proper keys must be in keyways. 10. Do not readjust fan RPM. If sheaves are replaced, use only sheaves of identical size and type. 11. If the unit is to be left idle for an extended period, it is recommended that the belts be removed and stored in a cool, dry place to avoid premature belt failure. 12. The standard pillow block bearings on belt driven ventilators are factory lubricated and are provided with external grease fittings.

Bearing Replacement Fan bearings on belt driven fans should not need to be replaced for many years if the previous recommendations are strictly adhered to. However, use the following procedure when bearing replacement is necessary. 1. Gain access to the fan bearings. Remove the bearing cover, if any. 2. Loosen the belts by shifting the motor. 3. Remove the propeller or wheel and disconnect the remote lube tubes (if applicable). 4.
