Amana HRV-150D, HRV-200D, HRV-300D manual Installation Examples, Ducting Fifth Port Units

INSTALLATION EXAMPLES

It is the responsibility of the installer to ensure all ductwork is sized and installed as designed to ensure the system will perform as intended. All air movement devices have a performance curve. The amount of air (CFM) that an HRV/ERV will deliver is directly related to the total external static pressure (E.S.P.) of the system. Static pressure is a measure of resistance imposed on the blower by length of duct work/number of fittings used in duct work, duct heater etc.

Ducting Fifth Port Units

All HRV(D)’s have a fifth duct port on top of the unit. This duct port is for both defrost and the recirculation mode. A motorized damper installed in the port closes during defrost or recirculation temporarily blocking the incoming fresh air-stream, allowing the warm air from the house to circulate through the HRV. You may wish to duct this port to a common clean air room (living room or dining room) so when recirculation is activated, household odors from the kitchen, bathroom or basement won’t be introduced into the living spaces of the home environment.

RADIANT HEATED HOMES

NOTE:

The recirculation function can be accessed with a optional digital control. It allows air to move gently throughout the home without exchanging air to the outside, until needed.
