WARNING
TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS, OBSERVE
THE FOLLOWING:
1. Use this unit only in the manner
intended by the manufacturer. If
you have any questions, contact the
manufacturer.
2. Before servicing or cleaning the 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.
3. To reduce the risk of fire and electric
shock, the integral damper end
switch should only be used to
switch ventilation equipment rated
Maximum 10A, 1/2 HP.
4. Sufficient 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.
5. I n 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.
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.
3. ZRT-IL is acceptable for use over a
tub or shower when installed in a
GFCI-protected circuit. If wired directly
to the fan or ZRT-IL, a single Ground
Fault Protector on the 120 VAC common
power supply must be used to protect
all devices on the same circuit.
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 heated or unheated
space, with consideration for the
potential of condensation in the ducting
or fan housing.
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 file 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.
DESCRIPTION
American Aldes patented* Zone Register
Terminals (ZRT
®)
are designed to introduce
flexibility and dynamic control to central
ventilation systems. Used in both large and
small systems, the ZRT-IL
zonally regulates
ventilation where it is required without the
need for individual fans. Each ZRT-IL is a
combination register box, control damper,
removable access plate, and optional flow
regulator(s). This unique combination
provides up to three different control
schemes without the need for expensive
pneumatic, electronic, or DDC control
systems.
The ZRT-IL can be ordered in a supply
or exhaust ventilation configuration. To
ensure the proper operation of the damper
assembly, do not exceed 1.0 in. w.g. of
differential pressure across the damper
door.
