HRV
DUCTING FIFTH PORT UNITS (R)
All SHR(D) / VHR / SER / VER Series R (1405R, 1505R, 2005R & 3005R) HRV / ERV’s have a fifth duct port on top (SHR(D)/SER) or
side (VHR/VER) 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 / ERV. 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.
INSTALLATION EXAMPLES
Example diagram only-duct configuration may change depending on model
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.

NOTE:
The recirculation function can be accessed with a optional EDF5 (5MR) intellitek control. It allows air to move gently throughout the
home without exchanging air to the outside, until needed.
