SOLERPALAU-USA.COM INSTALLATION, OPERATION AND MAINTENANCE MANUAL
TRC1200
RISK OF FIRE, ELECTRIC SHOCK, OR INJURY. OBSERVE ALL CODES AND THE FOLLOWING:
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.
SOUND ATTENUATION
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.
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 TRC1200 is insulated with high-density fiberglass. This provides significant attenuation of radiated sound.
The inlet ducts can be significant sources of radiated sound as well. The OA and RA ducts (inlet 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 OA and RA 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.
