Description

ALDES pending* In-Line Zone Terminals

(ZRT-SDIL) and High-Pressure In-Line Zone

Terminals (ZRT-SDIL-HP) are designed to introduce

exibility and dynamic control to central ventilation

systems. Used in both large and small systems, the

ZRT-SDIL/ZRT-SDIL-HP controls ventilation where

it is required without the need for individual fans.

Each ZRT-SDIL/ZRT-SDIL-HP is a combination control

damper and constant airow regulators. This unique

combination provides the ability to select between

low-ow and high-ow ventilation rates without the

need for expensive pneumatic, electronic, or DDC

control systems.

The ZRT-SDIL/ZRT-SDIL-HP can be used in a supply

or exhaust conguration. For ZRT-SDIL models,

operating range is 0.12 to 1.2 in. w.g. (30 to 300 Pa). For

ZRT-SDIL-HP models, the operating range is 0.4 to 2.8

in. w.g. (100 to 650 Pa).

The ZRT-SDIL/ZRT-SDIL-HP allows for a selection

between a continuous, regulated low airow rate

(damper closed) or an on-demand, regulated high

airow rate (damper opened). With a motorized

damper unpowered (closed) a low-continuous

amount of regulated airow passes through the

low-ow constantc airow regulator. When power is

applied to a motorized damper, the damper opens,

and air passes through the low-ow constant airow

regulator as well as the constant airow regulator in

the powered damper.

Mounting

The ZRT-SDIL/ZRT-SDIL-HP is intended to be installed

in-line in a duct system. The unit should be installed in a

location that provides access to the motorized damper.

Wiring

ZRT-SDIL/ZRT-SDIL-HP wiring needs to meet all applicable electrical

and building codes. If the electrical connection to the damper

motor wiring box is not accessible after mounting, there needs to

be enough slack (approximately 24”) in the electrical wiring leading

to the wiring box to allow the damper assembly to be removed

through the access opening. This will allow access to the electrical

connections from the access opening.

ZRT-SDIL/ZRT-SDIL-HP models are available with 24 VAC or 120 VAC

motorized dampers (see Figure 1 and 2 on the next page).

Maintenance

All motorized components of the ZRT-PDIL/ZRT-PDIL-HP are accessible

from the outside of the motorized damper.

Warning

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY

TO PERSONS, OBSERVE THE FOLLOWING:

1. Usethisunitonlyin the mannerintendedbythemanufacturer.

If you have any questions, contact the manufacturer.

2. Beforeservicingorcleaningtheunit,switchpoweroatservice

panel and lock service panel to prevent power from being

switched on accidentally. When the service disconnecting

meanscannotbe locked,securelyfastenaprominentwarning

device, such as a tag, to the service panel.

3. Sucient air is needed for proper combustion and exhausting

of gases through the flue (chimney) of fuel-burning

equipment to prevent backdrafting. Follow the heating

equipment manufacturer’s guidelines and safety standards,

such as those published by the National Fire Protection

Association (NFPA), and the American Society of Heating,

Refrigerating and Air-Conditioning Engineers (ASHRAE), and

the local code authorities.

4. In addition to the following manufacturer’s instructions, it is

necessary to comply with federal, state, and local government

codes. Your purchase of this 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 eects of excessive indoor

humidity.

5. Installation work and electrical wiring must be done by

qualied person(s) in accordance with all applicable codes

and standards, including re-rated construction.

6. When cutting or drilling into wall or ceiling, do not damage

electrical wiring and hidden utilities.

Caution

1. For general ventilating use only. Do not use to exhaust

hazardous or explosive materials and vapors.

2. Automatically operated device. To reduce the risk of injury,

disconnect from power supply before servicing.

System Design

Satisfactory performance of a central ventilation system requires:

• Proper integration of all the components, compatible grilles,

and wall/roof caps;

• Proper duct design for friction losses;

• Consideration of acoustic and vibration properties of the fan

and its mounting;

• Acoustic properties of the grilles;

• Consideration of the mode of operation, whether continuous

or automatically controlled by dehumidistat, timer, or

occupancy sensor;

• Installation in a heatedor unheatedspace,with consideration

forthepotentialofcondensationintheductingorfanhousing.

Inspect the carton upon receipt to ensure the terminal has not

been damaged in transit. If damaged, it is the responsibility of

the recipient to le a damage claim with the carrier. ALDES is not

responsible for damage incurred during shipment.

Note: Prior to installation, inspect the terminal to ensure that

damper(s) move freely and that the constant airow regulators

have not shifted during handling. 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.

1. AIRFLOW SETTING

Airow rate can be set or adjusted by rotating the dial from either side. The airow indicator will move

to show the selected CFM. The airow label has multiple dened setpoints, but the unique adjustment

mechanism of the CAR3 allows for innite adjustability between the minimum and maximum limits.

Performance charts found in the specications sheet reect this data, with the available range (shaded)

and marked setpoints (lines). The CAR3 will maintain the airow accurately to within +/- 10% of the

indicated lines below for each marked setpoint. At the higher airow rates, the minimum pressure

required to achieve the selected airow may exceed 0.12 in. w.g.

Each diameter has a unique range for both low- and high-pressure variants. The CAR3-L (low-pressure)

is designed for systems with pressures between 0.12 and 1.2 in. w.g. (30 to 300 Pa), and CAR3-H (high-

pressure) between 0.4 and 2.8 in. w.g. (100 to 700 Pa). Factory calibration of the CAR3 is available on

request. Blue color dial = Low-Pressure / Green color dial = High-Pressure.

The CAR3 should be installed in accordance with all applicable building and mechanical codes. If

installed in a metal duct or duct collar with a exible duct connector (listed to UL 2043), the CAR3 must

be inserted at least 1.2 times the duct diameter from the exible duct and/or duct connector.

Orient the CAR3 according to the airow direction

indicated on the device. Horizontal or vertical mounting

is acceptable.

5. TROUBLESHOOTING

PROBLEM CAUSE SOLUTION

AIRFLOW TOO LOW

Insufﬁcient duct pressure. Check fan ratings. Replace fan if too small

Increase fan speed.

Excessive duct air leakage. Seal ducts with mastic or tape.

CAR3 damper

not functioning properly.

Check CFM calibration on CAR3.

Adjust to proper airﬂow value.

AIRFLOW TOO HIGH

AND/ OR NOISY

OPERATION

CAR3 too close to fan. Add manual damper to reduce pressure

across CAR3 to normal operating range.

Fan at too high a speed. Lower fan speed.

CAR3 damper

not functioning properly.

Check CFM calibration on CAR3.

Adjust to proper airﬂow value.

4. MAINTENANCE & WARRANTY

• The CAR3 needs no maintenance when used in normal conditions. The addition of antimicrobial and

anti-static additives in the material increases the longevity and reliability of the CAR3. There is no risk

of dust deposit or obstruction because the CAR3 has no airways subject to clogging. If the intended

application includes air heavily loaded with dust or grease, access to the CAR3 should be possible

through the terminal device or with an access panel or door.

• ALDES Ventilation Corporation warrants the CAR3 to be free from manufacturing defects and

guarantees the performance within specied limits for a period of seven (7) years when installed in

normal environmental air systems for general residential and commercial heating, ventilating and air

conditioning. This warranty does not include installation in industrial

applications or caustic, noxious

or otherwise hazardous airhandling equipment. This warranty

is limited to replacement of the product

only and does not extend to consequential claims.
