Refer to Section 4.2 and observe the difference in the damper position
at the right in diagrams Defrost Mode 1 and Defrost Mode 2:
for Defrost Mode 1 the damper is completely closed, whereas for
Defrost Mode 2 the damper is half closed. At the factory, all ERVs are
assembled for defrost Mode 2. Therefore, if your installation is for an
ERV in a warm region (zone D as defined in Section 3), the rod must
be moved to position 1 (see figure 5).
NOTE: Before attempting to change the position of the damper rod, place
the unit on a table for easy access and remove the recovery core.
