Choose an appropriate location for the unit:
• Within an area of the house where the ambient temperature is kept between 50°F and 140°F;
• Away from living areas (dining room, living room, bedroom), if possible;
• So as to provide easy access to the interior cabinet for maintenance, and to the control panel on the side of the unit;
• Close to an exterior wall, so as to limit the length of the insulated fl exible ducts to and from the unit;
• HRV units only: close to a drain. If no drain is close by, use a pail to collect run-off;
• Away from hot chimneys, electrical panel and other fi re hazards;
• Within 6 feet of a power source (standard outlet).
Consumer Information
A. To ensure quiet operation of the ENERGY STAR certifi ed H/ERV, each product model must be installed using sound attenuation
techniques appropriate for the installation.
B. The way your heat/energy-recovery ventilator is installed can make a signifi cant difference to the electrical energy you use. To
minimize the electricity use of the heat/energy-recovery ventilator, a stand-alone fully ducted installation is recommended. If you
choose a simplifi ed installation that operates your furnace air handler for room-to-room ventilation, an electrically effi cient furnace that
has an electronically commutated (EC) variable speed blower motor will minimize your electrical energy consumption and operating
cost.
C. Installation of a user-accessible control with your product model will improve comfort and may signifi cantly reduce the product
model’s energy use.
