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 Airfl ow 
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 airfl ow, 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 (airfl ow and  acoustic 
properties of the supply/exhaust 
grilles, and compatible wall/roof caps

Method of balancing airfl ows 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 fi le 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 fi nal location.  The 
fan may be installed in a mechanical 
room, crawl space or attic.  It is designed 
to be placed on a fl at surface, against 
a wall or trusses, or suspended from 
above.  If set on a fl at 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 
confi guration may exist on some derived 
models.  Refer to supplement where 
appropriate). Orient the fan so that the 
access door can be opened for service.

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
