Take these simple steps to attenuate noise from the unit:
OUTSIDE THE BUILDING
Exhaust velocity noise is the primary cause of unit-
related noise outside the building. Size the exhaust
duct and grille for less than 1000 FPM air velocity.
When practical, orient the exhaust air hood to point
away from houses or public areas.
DUCTS
Make sure the ductwork at the unit outlets is stiff
enough to resist the flexure and resulting booming
associated with system start-up and shut-off, as well
as the turbulent flow conditions at the blower outlets.
In general, provide smooth transitions from the ERV’s
outlets to the duct. The ducts connecting to the
outlets should be straight for a sufficient distance,
with gradual transitions to the final duct size.
These guidelines are consistent with SMACNA
recommended duct layout practices for efficient and
quiet air movement. Follow SMACNA guidelines.
RADIATED NOISE
The TRC1600 is insulated with high-density
fiberglass. This provides significant attenuation of
radiated sound.
The outlet ducts can be significant sources of
radiated sound as well. The FA and EA ducts
(outlet ducts) should be insulated for sound
control. This insulation should start at the unit.
At a minimum the first ten feet of duct should be
insulated. All parts of the FA and EA ducts located
in the mechanical space should be insulated for
sound control, both to minimize sound radiation out
of these ducts and also to control sound radiation
into the ducts.
AERODYNAMIC (VELOCITY) NOISE
When sound attenuation is a design concern, the
primary consideration is velocity noise at the unit’s
Fresh Air blower outlet. The average velocity at
the blower outlets is 3642 FPM when the unit is
operating at 1500 CFM.
SOUND ATTENUATION
1. Before servicing or cleaning the unit, switch
power off at disconnect switch or service panel
and lock-out/tag-out to prevent power from
being switched on accidentally. More than
one disconnect switch may be required to de-
energize the equipment for servicing.
2. This installation manual shows the suggested
installation method. Additional measures may
be required by local codes and standards.
3. Installation work and electrical wiring must be
done by qualified professional(s) in accordance
with all applicable codes, standards and
licensing requirements.
4. Any structural alterations necessary for
installation must comply with all applicable
building, health, and safety code requirements.
5. This unit must be grounded.
6. Sufficient air is needed for proper combustion
and exhausting of gases through the flue
(chimney) of fuel burning equipment that
might be installed in the area affected by this
equipment. If this unit is exhausting air from
a space in which chimney-vented fuel burning
equipment is located, take steps to assure that
combustion air supply
is not affected. Follow the heating equipment
manufacturer’s requirements and the
combustion air supply requirements of
applicable codes and standards.
7. Use the unit only in the manner intended by the
manufacturer. If you have questions, contact
the manufacturer.
8. This unit is intended for general ventilating
only. Do not use to exhaust hazardous or
explosive materials and vapors. Do not connect
this unit to range hoods, fume hoods or
collection systems for toxics.
9. When cutting or drilling into wall or ceiling, do
not damage electrical wiring and other hidden
utilities.
10. If installed indoors this unit must be properly
ducted to the outdoors.
RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:
WARNING
To avoid motor bearing damage
and noisy and/or unbalanced
blowers, keep drywall spray,
construction dust, etc., out of unit.
CAUTION
Do not remove or disable the
wiring interconnection between the
Overload Relays and the Contactors.
Without this interconnection the
motor(s) will not be protected
against overload.
CAUTION
Danger of Electrical Shock when
servicing an installed unit.
ALWAYS DISCONNECT POWER
SOURCE BEFORE SERVICING!
More than one disconnect switch
may be required.
Proper Wiring Size Selection
and Wiring Installation are the
Responsibility of the Electrical
Contractor.
