AIRFLOW & ZONE CONTROL
ZONE REGISTER TERMINAL
Description
ALDES patented* Zone Register Terminals (ZRT®) are
designed to introduce exibility and dynamic control to
central ventilation systems. Used in residential applications,
the ZRT® zonally regulates ventilation where it is required
without the need for individual fans. Each ZRT® is a
combination grille, register box, and control damper.
To ensure the proper operation of the damper assembly,
do not exceed 1.0 in. w.g. of dierential pressure across the
damper door. ZRT® 6" supply models require a minimum
ow constant airow regulator.
By replacing static grilles in large central systems, the ZRT-1
model provides on-o control for on-demand ventilation.
This allows central fan downsizing and promotes energy
savings by minimizing necessary fan horsepower and
ventilation-induced heat and cooling loads on the home.
The ZRT-2 model can be used for combination low-ow
indoor air quality ventilation and on-demand high-ow
spot ventilation using the same central fan system. This
is achieved by integrating a minimum constant airow
regulator directly into the damper sub-assembly. With the
damper completely closed, the constant airlfow regulator
will allow steady, low-continuous ventilation during fan
operation. When other terminals are opened for on-
demand control of spot ventilation, the closed ZRT-2 will
maintain the set low-continuous rate through the constant
airow regulator minimum ow control. By opening the
ZRT-2’s control damper, the low-ow regulator is removed
from the air stream, allowing unrestricted maximum-boost
ventilation.
Airow rate can be set or adjusted by rotating the dial
from either side. The airow indicator will move to show
the selected CFM. The airow label has multiple dened
setpoints, but the unique adjustment mechanism of the
CAR3 allows for innite adjustability between the minimum
and maximum limits.
The ZRT® can activate fans used in central ventilation
systems.Through the use of an integral damper end-switch,
the ZRT® can trigger the remote fan to start. This provides
the distinct advantage of allowing the fan to only ventilate
specic spaces when called upon, without the need for
separate fans in each space. This is especially important
in residential bath applications using popular in-line and
multi-port fans, where low noise and a single exterior vent
penetration are desired.

Product Description
Ventergy® Series Multi-Port Ventilators (MPVS) are highly versatile,
continuous-duty rated fan units for residential and light commercial
applications. They meet ENERGY STAR eciency criteria for low energy
consumption. The most popular use for the fan is central exhaust
ventilation of bathrooms, kitchens, laundry rooms, and other rooms
where humidity is a controlling factor since the fan has a single exhaust
discharge duct directly to the outdoors.
The principal advantage of the MPVS is the elimination of standard noisy
bath fans, with the benets of quiet operation and reduced penetrations
to the exterior of the building. With the increasingly tight construction
of energy-ecient buildings, there is a growing need for mechanical
ventilation for indoor air quality. These fans are designed to serve this
purposebyprovidingeectivebathroomventilationwiththeabilitytorun
intermittently or continuously. The quiet, energy-ecient, permanent-
split-capacitor type of external-rotor motor has permanently sealed
bearings that provide many years of maintenance-free performance.
Construction
The MPVS is constructed of heavy-gauge galvanized steel to prevent
corrosion caused by moisture. The cabinet is internally lined with
acoustic, closed-cell foam insulation that acts as a vapor barrier. This
allows installation directly above living spaces or in unheated plenum
spaces without concern for noise or condensation.
Controls
The fans can be operated manually or automatically by a programmable
timer or dehumidistat. They may also be operated in conjunction with
a variable speed control.
Ducting the Fan
Theducting from this fantotheoutside ofthe buildinghasastrongeect
ontheairow,noise and energyuseofthefan.Usetheshortest,straightest
duct routing possible for best performance, and avoid installing the fan
with smaller ducts than recommended. Insulation around the ducts can
reduce energy loss and inhibit mold growth. Fans installed with existing
ducts may not achieve their rated airow.
Use ductwork of a diameter that is the same as or greater than the
diameter of the duct connectors on the fan.

Upon receipt, inspect the carton to ensure 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. ALDES North
America 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 are 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
damaged, loose, or missing parts.
A location should be chosen that will minimize the length of
duct runs and the number of elbows that are required. If more
than four (4) 90oelbows are required, 45oelbows should be
used. If insulated exible duct is used, the inner sleeve should
be fully expanded over the entire duct run. Any turns that are
necessary in the exible duct run should be made as gradually
as possible. Choose roof and/or wall caps that are of a more
open, less restrictive design. The perimeter of all ceiling and wall
penetrations for ductwork and grille(s) should be properly sealed
with caulk or a similar material to ensure that there is not an air
leakage path between the device and the wall and/or ceiling.
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 the ceiling. Alternately, the fan may be suspended using
threaded rods or chains. At least 12 inches clearance from the
access panel is needed to permit servicing the motor. Loose ll
or batt insulation can be installed over the unit if the unit’s access
doors can still be opened.

Cold Climate Precautions
If installed in an unheated space in cold climates, there is a
possibility of condensation forming in the fan housing or ducting
components. A backdraft damper installed at each grille is an
eective way to reduce the potential for condensation when
the fan is cycled on and o. Insulated ducting must be used
where exposed to cold attic or crawl space temperatures to avoid
condensation in the ducting. Condensation can also be avoided
by continuous operation of the fan.

codes. Your purchase of this ALDES North America system
represents an investment in the health and comfort of occupants,
as well as an investment in the protection of the building from the
damaging eects 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, above a drop ceiling, in a closet or in a laundry
room, to provide quiet exhaust of stale, humid, or otherwise
polluted air from bathrooms, kitchens, laundry rooms, 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, such 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 Constant Airow Regulators (CAR) 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 airow, 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 (airow and acoustic properties of the supply/
exhaust grilles), and compatible wall/roof caps
• Method of balancing airows of multi-point ventilation systems
• Consideration for potential condensation in the ducting or fan
housing (installation in an unheated space)
Duct Connections
Ducting may be exible or rigid, depending on local codes. If
permitted by code, insulated exible ducting is recommended.
To limit fan noise, at least 8 feet of insulated exible duct shall
be installed between the fan and grille(s). All exible duct
connections shall be secured with clamps or wire ties and
sealed with mastic or code-approved duct tape. All rigid ducts
are to be sealed on both ends and along the longitudinal seams
with mastic or code-approved duct tape.
Ducting shouldconform toNFPA90A and meettherequirements
of UL as a Class 0 or Class 1 duct to specication UL 181, Standard
for Factory-Made Air Ducts and Duct Connectors.

Impact of Exhaust Fans
In especially tight homes heated with naturally vented
appliances, such as gas, oil or wood-red furnaces, boilers,
stoves or replaces, the exhaust system may produce sucient
negative pressure indoors to induce the backdrafting of ue
gases. This is a common, though intermittent, occurrence, with
conventional exhaust systems, such as vented kitchen range
hoods, clothes dryers, bath fans, etc. In the case of continuous
exhaust, though often at lower ow rates, the potential for
backdrafting the ue of these appliances does exist and
represents a dangerous situation.
The International Fuel Gas Code, Appendix D provides a
Recommended Procedure for Safety Inspection of an Existing
Appliance Installation. This procedure should be followed to
determine the presence of adequate combustion air while all
exhaust fans are operating at maximum speed and all doors
and windows are closed.
In the event that backdrafting occurs, steps must be taken
to provide sucient combustion air to the furnace or boiler,
following the guidelines of the National Fuel Gas Code and all
state and local codes.
RDF 8-8MAX and RDF 12-8 RDF 8-8IP and RDF 12-8IP
Mechanical Supply Fans
Mechanical supply of outdoor air tends to reduce the
potential and frequency of backdrafting by reducing
the contributing negative pressures; however, due
to a multitude of factors, including the wide range
of exhausting appliances that may be present, the
eects of wind and building shape, the presence of
multiple chimneys, building leakage, and the use of
operable windows, no one can assure elimination of
backdraft conditions so long as atmospherically vented
combustion equipment is present in the home.
ALDES North America accepts no liability for backdraft conditions resulting from negative pressures. Nor does ALDES North America
make representation that blending supply ventilators (BVS) are adequate to prevent such occurrences.

For installations in which the fan is connected to a range hood, or if an exhaust grille connected to the fan is located near the cooking surface (as shown below),
be sure to observe the following safety warnings:
Warning
TO REDUCE THE RISK OF FIRE, USE ONLY GALVANIZED STEEL
DUCTWORK WHEN REQUIRED TO USE METAL DUCT.
NOTE: If only rigid ducting is allowed, a metal sound attenuator
shall be installed between the fan and the range hood.
NOTE: If the fan is not connected to a range hood or a grille in the
vicinity of the cooking surface, other approved ducting may be used
as described in the “Duct Connections” section of basic instructions.
Range Hood/Cooking Surface Warning
TO REDUCE THE RISK OF INJURY TO PERSONS IN THE EVENT OF A RANGE-TOP GREASE FIRE, OBSERVE THE FOLLOWING:
1. Never leave surface units unattended at high settings. Boilovers cause smoking and greasy spillovers that may ignite.
Heat oils slowly on low or medium settings.
2. Always turn range hood ON when cooking at high heat or ambeing food.
3. Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or lter. Use proper pan size.
Always use cookware appropriate for the size of the surface element.
4. SMOTHER FLAMES with a close-tting lid, cookie sheet, or metal tray, then turn o the burner. BE CAREFUL TO PREVENT
BURNS. If the ames do not go out immediately, EVACUATE AND CALL THE FIRE DEPARTMENT.
5. NEVER PICK UP A FLAMING PAN - You may be burned.
6. DO NOT USE WATER, including wet dishcloths or towels, because a violent steam explosion could result.
7. Use an extinguisher ONLY if:
1. You know you have a Class ABC extinguisher, and you already know how to operate it.
2. The re is small and contained in the area where it started.
3. The re department is being called.
4. You can ght the re with your back to an exit. Based on “Kitchen Fire Safety Tips” published by NFPA.
