Introduction

Handling

Storage

Shipment and Receiving

Handle your equipment with caution. Some fans are pro-

vided 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.

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, fans should be protected

from the elements as completely 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 longer

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: Check units for rotation. For three-phase, rotation can be changed by interchanging any two of the three line leads. If 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. 4. Electrical Input Check: Perform check of fan ampere draw and verify that motor nameplate amps are not exceeded. Take into account the service factor range if motor is nameplated above a 1.

V-Belts V-belts on these belt driven fans are oil, heat, and static resistant type and oversized for continuous duty. With proper installation and maintenance, years of operating efficiency can be added to the lifespan of the V-belt drive. The condition of V-belts and the amount of belt tension should be checked prior to start-up (see Figure 1). When it becomes necessary to adjust belt tension, do not overtension as bearing damage will occur.

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 lines (if applicable). 4.
