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. 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 effects of excessive indoor
humidity.
6. Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable codes
and standards, including fire-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. ZRT
®
is acceptable for use over a tub or shower when
installed in a GFCI-protected circuit. If wired directly to the
fan or ZRT
®
, 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. 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).
