Bases (Foundation and Isolation)

In order to assure continued alignment, a high strength, non-shrink epoxy grout is recommended to provide the desired mechanical properties for support of the fan. This type of support ensures the appropriate transmission of static and dynamic loads to the equipment foundation.

To eliminate vibration and noise from being transferred to the building, vibration isolators should be used. The fan is mounted directly on the base and must be supported for the entire length of the fan base angle. Isolators are installed between the base and the foundation.

After the fan and isolators are installed, the entire assembly must be leveled. Position the level on the base, not the fan shaft, for proper leveling. Additionally, the motor and fan shafts must be level and parallel relative to each other for proper alignment.

Belt Guards

If the belt guard is not factory mounted, then it must be field mounted. Brackets and mounting hardware are the responsibility of the installer. Mounting bracket locations vary with motor mounting position, arrangement, and fan type. The bearing supports and fan structure are used in most instances and when the motor is not mounted to the fan itself, a bracket should also be located near it. This information is intended as only a guide and actual field conditions may dictate another mounting location for the guard brackets. Refer to local codes for securing guarding.

Drain Connection

Make sure to either connect the drain or keep it plugged. Never leave the drain open to drain freely. The drain line must be installed using either a U-trap arrangement or an equivalent method (drain leg is submerged in liquid). To obtain a proper seal, the leg length must be greater than the system pressure drop.

Ductwork / Stacks

All ductwork and/or stacks must be self-supporting and independent of the fan. The fan inlet and outlet are not designed to support the connecting duct or stack. The use of flexible connectors is recommended to limit the transmission of stress to the fan. Excessive pressure applied when bolting a flange connection may cause damage to the fan housing or flange.

Rotatable Housings

It may be necessary to rotate the scroll of the fan to achieve a different discharge position than what was originally supplied. Fiberglass fan model BCSW- FRP (sizes 6-25; arr. 4 and 10, Class I, II, III, and

IV) has the flexibility to be rotated in the field. This is accomplished by removing the housing bolts, rotating the housing to a new discharge position and reinstalling the bolts.
