aldes ZRT-SDIL Installation, Operation And Maintenance Instructions

Description

ALDES pending* In-Line
(ZRT-SDIL) and High-Pressure
Terminals (ZRT-SDIL-HP) are designed to introduce
flexibility 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 airflow regulators. This unique
combination provides the ability to select between
low-flow and high-flow 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 configuration. 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 airflow rate
(damper closed) or an on-demand, regulated high
airflow rate (damper opened). With a motorized
damper unpowered (closed) a low-continuous
amount of regulated airflow passes through the
low-flow constantc airflow regulator. When power is
applied to a motorized damper, the damper opens,
and air passes through the low-flow constant airflow
regulator as well as the constant airflow 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.
