The ERV has become an integral component of the HVAC system. Figure A shows an ERV unit providing 

fresh air directly to the return air plenum of a rooftop heat/cool unit.  
In the balanced airflow system, the ERV exhaust removes stale room air (eg. from lunch room, storage or 

copy area) and returns to the space an equal amount of fresh outdoor air, making the use of an 

economizer obsolete in conjunction with an ERV.  

 
 
 
 

 

 

 

 

 

 

 

Note

 

•

 

At no time should the air handler T.E.S.P. on the return duct exceed that of the ERV. 

Caution

 

•

 

When interlocking a rooftop unit with an ERV take care to ensure the fans of both units 

operate in the correct rotation.
