INSTALLATION

4.3 SOUND ATTENUATION

Take these simple steps to attenuate noise from the unit. 
 
4.3.1 Outside the Building
The exhaust hood is the primary source of noise outside the building. When practical, orient the 
exhaust air hood to point away from houses or public areas. 
 
4.3.2 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. 
 
4.3.3 Radiated Noise
The HE1.5XIN is insulated with high-density fiberglass. This provides significant attenuation  
of radiated sound from the unit itself.
The outlet ducts can be significant sources of radiated sound as well. The FA duct should be 
insulated for sound control. This insulation should start at the unit. At a minimum the first 10' of 
duct should be insulated. All parts of the FA and RA ducts located in a mechanical space with 
noise-generating equipment also should be insulated for sound control, both to minimize sound 
radiation out of the FA duct, and also to control sound radiation into both ducts.

5.2 FLOOR INSTALLATION

Most units are installed in a location specified by others. In general, it is preferable to install the 
unit on a flat, reasonably level surface, such as a concrete floor. When positioning the unit, it is 
not to be slid on its legs because they can be bent. 

5.1 DUCTWORK

5.1.1 Ducts to the Outside
The exhaust outlet and fresh air inlet on the outside of the building should be at least 10' apart 
to avoid cross-contamination. The exhaust outlet should not dump air into an enclosed space or 
any other structure. The inlets and outlets should be screened against insects and vermin and 
shielded from the weather to prevent the entry of rain or snow.
Ducts connecting the HE1.5XIN to the outside must be insulated, with sealed vapor barrier on 
both inside and outside of the insulation. Insulate both the Outside Air (OA) and Exhaust Air (EA) 
ducts. 
 
5.1.2 Inside Ductwork System
Ensure Good Ductwork Design 
Ductwork should be designed to allow the unit to provide the required airflow and reduce 
pressure drop for efficient, quiet operation. If the inside ducts run through unconditioned spaces 
they must be insulated with a sealed vapor barrier on both inside and outside of insulation.

NOTE: Ducts inside 

a building that are 

connected to the 

outside must be 

insulated with a sealed 

vapor barrier on both the 

inside and the outside of the 

insulation.

Tape both inner and outer 

vapor barriers of insulated 

duct to collars on duct 

adapters. This is critical to 

prevent migration of mois-

ture into insulation. Build-up 

of moisture can result in 

failure of the duct system 

and/or frost in the insula-

tion. Make sure any tears 

in the inner and outer vapor 

barriers are sealed.
