SELECT LOCATION
The ERV should be located in a conditioned space and in close
proximity to a fused power source. It should be easily accessible
for routine maintenance.
If ERV is installed independent of a forced-air system, unit should
be located near the center of the air distribution system. If ERV is
installed in conjunction with a forced-air system, unit should be
located next (or close to) the indoor equipment.
