Warning
TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR INJURY
TO PERSONS, OBSERVE THE FOLLOWING:
1. Usethis unitonlyinthemanner intendedby themanufacturer.
If you have any questions, contact the manufacturer.
2. Beforeservicing orcleaning theunit, switchpoweroatservice
panel and lock service panel to prevent power from being
switched on accidentally. When the service disconnecting
meanscannotbe locked,securelyfastena prominentwarning
device, such as a tag, to the service panel.
3. To reduce the risk of re and electric shock, the integral
damper end switch should only be used to switch ventilation
equipment rated Maximum 10A, 1/2 HP.
4. Sucient 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. 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 eects of excessive indoor
humidity.
6. Installation work and electrical wiring must be done by
qualied person(s) in accordance with all applicable codes
and standards, including re-rated construction.
7. 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.
3. A wall-insert fan intended for installation over a bathtub or
shower must be installed in a GFCI-protected circuit at least
5 feet (1.5 m) above the oor.
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 heatedorunheatedspace,withconsideration
forthepotentialofcondensationinthe ducting orfanhousing.
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.
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.
Clean the grille monthly (if so equipped).
Mounting
The ZRT-W is available with mounting brackets to accommodate
new or existing construction. See Figure 1.
Wiring
The ZRT-W is available with 24 VAC or 120 VAC actuator motors.
120 VAC wiring options are shown in Figures 2-4, and 24 VAC
wiring options using the Zone Terminal Fan Control Center
(Model ZTC) are shown in Figures 5 and 6.
