WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:

A.Use this unit only in the manner intended by the manufacturer. If you have any questions, contact the manufacturer.

B.Before servicing or cleaning unit, switch power off at service panel and lock service panel to prevent power from being switched on accidentally. When the service disconnecting means cannot be locked, securely fasten a prominent warning device, such as a tag to the service panel.

In addition to the following manufacturer’s instructions, it is necessary to comply with federal, state, and local government codes. Your purchase of this American ALDES ventilation system represents an investment in the health and comfort of the occupants, as well as an investment in the protection of the building from the damaging effects of excessive indoor humidity.

This model of centrifugal fan is designed for multiple purposes. It may be used as an in-line rectangular duct fan (Model RDF) or a manifolded, multi-port fan for multiple exhaust or supply points. It may be installed in a remote location such as an attic space, mechanical room or above a drop ceiling, in a closet or laundry room, to provide quiet exhaust of stale, humid, or otherwise polluted air from bathrooms, the kitchen, laundry, or storage rooms, via exhaust grilles and ducting to the centrally located fan, which is ducted to the outdoors. With small return grilles in bedrooms and other areas, and one duct connection

to the outdoors, as the BVS models, it may also be used as a supply ventilator or recirculating central ventilator for the introduction of outdoor air, raising the temperature of the fresh air by mixing with recirculated indoor air. When used with adjustable balancing grilles or ALDES CAR, Constant Airflow Regulators, and compatible roof/wall caps, ducting, etc., the fan is the heart of a complete pre-engineered ventilation system.

SYSTEM DESIGN:

Satisfactory performance of a central ventilation system requires the proper integration of all the components:

•Fan selection for airflow, pressure and acoustic properties, vibration characteristics and mounting method, and mode of operation (continuous, manually or automatically controlled)

•Proper duct design for friction losses, with compatible supply or exhaust grilles (airflow and acoustic properties of the supply/exhaust grilles, and compatible wall/roof caps

•Method of balancing airflows of multi-point ventilation systems

•Consideration for the potential of condensation in the ducting or fan housing (installation in an unheated space)

Upon receipt, inspect the carton to insure the fan has not been damaged in transit. If damaged, it is the responsibility of the recipient to file a damage claim with the carrier. American ALDES Ventilation Corporation is not responsible for damage incurred during shipment.

Handle the unit with care to prevent damage to the housing and other components. Store the unit indoors if possible. If outdoor storage is required, protection against moisture and dirt is necessary.

Unpack the unit, taking care to look for any loose components among the packing material. Make certain that the fan housing and the blower is free of any loose packing material or small parts.

If not removed before startup, damage and injury may result from solid objects discharged by the blower. Inspect for damage, loose or missing parts.

Install the unit in its final location. The fan may be installed in a mechanical room, crawl space or attic. It is designed to be placed on a flat surface, against

a wall or trusses, or suspended from above. If set on a flat surface, vibration isolation pads are recommended. Mounting brackets with rubber grommets are supplied to permit installation against a vertical surface or from a ceiling above. Alternatively, it may be suspended using threaded rods or chains. At least 12 inches clearance is needed from the access panel to permit servicing the motor.

MOUNTING INSTRUCTIONS (Differences in bracket type and configuration may exist on some derived models. Refer to supplement where appropriate). Orient the fan so that the access door can be opened for service.

Tools Required:

Power screwdriver with

No. 2 Philips bit.

Mounting brackets are supplied with the fan. The brackets may be mounted to the fan using the self-drilling screws and rubber grommets provided, at the locations indicated by dimple marks on the side and bottom panels of the fan. Pan head number 10 screws are provided to attach the mounting bracket to the building framing members. It may be necessary to add additional framing members to span wall studs. It is not recommended to use drywall anchors to support the fan. If installed against a concrete or masonry wall, concrete
