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 Air 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 air 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 (air ow and acoustic
properties of the supply/exhaust
grilles, and compatible wall/roof caps
Method of balancing air 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 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 nal location. The
fan may be installed in a mechanical
room, crawl space or attic. It is designed
to be placed on a at surface, against
a wall or trusses, or suspended from
above. If set on a 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
con 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.
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
