INSTALLATION POSITION

Ductless e2 ventilation devices with heat recovery can only function in pairs operation in opposite directions.

Each fan operates 70 seconds (50 seconds for e2 short) in supply air operation, the other 70 seconds (50

seconds for e2 short) in exhaust air operation at the corresponding set flow rates. After which both air flows

directions are changed. This assures that the total of supplied ventilation volume is equal to the total exhausted

volume. If a pair of fans in this balanced push-pull operation is installed in two different rooms of a dwelling, a

sufficiently dimensioned interconnection (undercut door, etc.) between the rooms should be installed to allow

unrestricted air movement between these spaces. Please see the product page at foursevenfive.com for videos.

OPERATING CONDITIONS

Rated conditions: 5ºF to 104ºF (-15ºC to +40ºC) with relative humidity up to 65%.

During the heating period it is possible for very small amounts of condensation to form on grills if such conditions

arise. If these limitations of use are exceeded for extended periods of time, the device can be closed with the

indoor cover. Do ensure IAQ is maintained in such cases.
